Overall Evaluation of Data and Potential Usability Issues

The following is a summary of the site investigationassessment objectives

bull To collect preliminary waste characterization data for the sludge present in disposal lagoons (Areas I and II) at the site

bull To gain an increased understanding of the sludge characteristic which are needed to determine disposal options

bull This sampling event is a preliminary phase to develop a privately funded cleanup alternative for the site The data are not intended for risk assessment purposes and therefore are not subject to rigorous QAQC requirements

All of the field samples exhibited significant concentrations of dioxin and furans As a result some analyte concentrations were reported above the instrument calibration range and some analyte concentrations saturated the instrument detector These problems could lead to improper

peak integrations and analyte quantitation The reported results should be considered minimum values Since all of the positive results are included in TE calculations TE values for the samples must be considered estimated values as well The Toxicity Equivalency (TE) values ranged between 56 and 4600 ppt

The laboratory did not perform dilutions as per clients instructions Therefore the reported results have limited use as the results are estimated

Samples AR01-SS02 and AR02-TP03 arrived broken at the laboratory and therefore the corresponding locations were resampled on October 31 2000 The samples AR01-SS02 AR02shyTP03 and AR02-TP03D were received in the laboratory on November 4 2001

One of the objectives of this project was to determine whether or not the waste generated at the site should be classified as an F021 listed hazardous waste as specified in 40 CFR 26831 All of the sampled analyzed contained hazardous constituents ie TCDD TCDF PeCDD PeCDF HxCDD and HxCDF at or above the 1 ppb (ugKg) standard in Subpart D 26840

Data Completeness (CSf Audit - Tier I)

The following data or information in the data package had discrepancies andor were missing

Preservation and Holding Times

All of the samples were received at temperatures gt 4degC ( 8degC and 10degC respectively) therefore all of the results were estimated (J) and (UJ) According to Method 1613 preservation criterion solid and semi-solid samples must be kept in the dark at lt 4degC from the time of collection until receipt at the laboratory

The following table summarizes the clean-up standard recoveries that did not meet Method 1613 acceptance criterion of 35-197

Standard Action Affected Samples Recovery

Positive NDs Detects

C14 -TCDD 291 J UJ AR01-SS03

Professional judgement was used to estimate all of the non-labeled congener results (J UJ) since low recoveries may indicate interferences during the clean-up process resulting in biased results

Ms Christine Clark March 23 2001 Page 6 B-01-03-Z-04

Revised April 6 2001

Sample Ouantitation

All of the samples from this SDG had significant concentrations of analytes As a result some samples had analyte concentrations which were outside the calibration range of the instrument These analyte concentrations are flagged OLR on Form Is and estimated (J ) on the Data Summary Table The following sample results were reported outside the calibration range

AR01-SS01 1234678-HpCDD AR01-SS02 OCDD AR01-SS03 OCDD AR02-TP03 123678-HxCDD AR02-TP03D 1234678-HpCDF AR02-TP04 123678-HxCDD AR02-TP05 123678-HxCDD 123789-HxCDD 1234678-HpCDF

Additionally some samples had analyte concentrations which saturated the instrument detector These analyte concentrations are flagged MC on Form Is and they are estimated (J) on the Data Summary Table The following sample results were affected

AR01-SS01 OCDD AR02-TP03 1 234678-HpCDD OCDD 1 234678-HpCDF OCDF AR02-TP03D 1234678-HpCDD OCDD OCDF AR02-TP04 1234678-HpCDD OCDD 1234678-HpCDF OCDF AR02-TP05 1234678-HpCDD OCDD OCDF

The accuracy of the quantitation is unknown when the reported concentrations are outside the calibration range of the instrument or when there are indications of a saturated detector Also since all of the positive results are included in TE calculations including analytes flagged as OLR or MC TE values for the samples must be considered estimated values

The laboratory did not perform sample dilutions as per clients instructions

2378-TCDD Toxicity Euivalents (TE and Isomer Secificit

All TE values are calculated by the ESAT data validator using the validated data The data validation process may alter the laboratorys reported TE values Region I TE calculations include the data validation results for blanks sample dilution and reported EMPC values These calculated values are reported on the Data Summary Tables The TEF values provided in Table 10 of EPA Method 8290A Rev 1 January 1998 are the ones published in EPA6253-89016 Interim Procedures for Estimating Risks Associated with Exposure to Mixtures of Chlorinated Dibenzo-p-Dioxins and Dibenzofurans (CDDs and CDFs) 1 989 Update Part II page 1 3 and are the ones used in these calculations

Ms Christine Clark March 23 2001 Page B-01-03-Z-04

Revised April 6 2001

System Performance

No major trends were noted Data validation indicated that poor field duplicate precision and ion ratio of the internal standards outside method acceptance criteria were due to the interferencecontribution from the high concentrations of native analytes in the samples and not poor laboratory performance

VI COLUMN PERFORMANCE RESOLUTION CHECK (Method I6I3B amp 8290A)

Date ID

Was the chromatographic resolution of the TCDDTCDF isomers and the in the CC3 or CS3 solution far DB-5 columns calculated for each 12 hour period ^mdash^^

Valley -TCDD -TCDD (QC Limit s 25)

Valley -TCDF -TCDF (QC Limit s 50)

For DB-225 columns

Valley -TCDD -TCDD (QC Limit lt 25)

Valley -TCDF -TCDF (QC Limit i 50)

ACTIONS

A If the GC resolution criteria do not meet specifications the positive hits will be qualified as J All tetras and hexas (for both dioxin and furans) will be qualified The heptas are not believed to be affected OCDD and OCDF are not affected as there is only one isomer in each group No action is taken for non-detects

B The criteria for chromatographic resolution must be met for all standards and the reviewer must use professional judgement on the severity of the problem and its effect on the final results

ACTIONS

A If the GC resolution criteria do not meet specifications the positive hits will be qualified as J All tetras and hexas (for both dioxin and furans) will be qualified The heptas are not believed to be affected OCDD and OCDF are not affected as there is only one isomer in each group No action is taken for non-detects

B The criteria for chromatographic resolution must be met for all standards and the reviewer must use professional judgement on the severity of the problem and its effect on the final results

ACTIONS

A If the GC resolution criteria do not meet specifications the positive hits will be qualified as J All tetras and hexas (for both dioxin and furans) will be qualified The heptas are not believed to be affected OCDD and OCDF are not affected as there is only one isomer in each group No action is taken for non-detects

B The criteria for chromatographic resolution must be met for all standards and the reviewer must use professional judgement on the severity of the problem and its effect on the final results

VI COLUMN PERFORMANCE RESOLUTION CHECK (Method I6I3B amp 8290A)

Date ID

Was the chromatographic resolution of the TCDDTCDF isomers and the in the CC3 or CS3 solution far DB-5 columns calculated for each 12 hour period ^mdash^^

Valley -TCDD -TCDD (QC Limit s 25)

Valley -TCDF -TCDF (QC Limit s 50)

For DB-225 columns

Valley -TCDD -TCDD (QC Limit lt 25)

Valley -TCDF -TCDF (QC Limit i 50)

ACTIONS

A If the GC resolution criteria do not meet specifications the positive hits will be qualified as J All tetras and hexas (for both dioxin and furans) will be qualified The heptas are not believed to be affected OCDD and OCDF are not affected as there is only one isomer in each group No action is taken for non-detects

B The criteria for chromatographic resolution must be met for all standards and the reviewer must use professional judgement on the severity of the problem and its effect on the final results

VI COLUMN PERFORMANCE RESOLUTION CHECK (Method I6I3B amp 8290A)

Date ID

Was the chromatographic resolution of the TCDDTCDF isomers and the in the CC3 or CS3 solution far DB-5 columns calculated for each 12 hour period ^mdash^^

Valley -TCDD -TCDD (QC Limit s 25)

Valley -TCDF -TCDF (QC Limit s 50)

For DB-225 columns

Valley -TCDD -TCDD (QC Limit lt 25)

Valley -TCDF -TCDF (QC Limit i 50)

ACTIONS

A If the GC resolution criteria do not meet specifications the positive hits will be qualified as J All tetras and hexas (for both dioxin and furans) will be qualified The heptas are not believed to be affected OCDD and OCDF are not affected as there is only one isomer in each group No action is taken for non-detects

B The criteria for chromatographic resolution must be met for all standards and the reviewer must use professional judgement on the severity of the problem and its effect on the final results

VI COLUMN PERFORMANCE RESOLUTION CHECK (Method I6I3B amp 8290A)

Date ID

Was the chromatographic resolution of the TCDDTCDF isomers and the in the CC3 or CS3 solution far DB-5 columns calculated for each 12 hour period ^mdash^^

Valley -TCDD -TCDD (QC Limit s 25)

Valley -TCDF -TCDF (QC Limit s 50)

For DB-225 columns

Valley -TCDD -TCDD (QC Limit lt 25)

Valley -TCDF -TCDF (QC Limit i 50)

ACTIONS

A If the GC resolution criteria do not meet specifications the positive hits will be qualified as J All tetras and hexas (for both dioxin and furans) will be qualified The heptas are not believed to be affected OCDD and OCDF are not affected as there is only one isomer in each group No action is taken for non-detects

B The criteria for chromatographic resolution must be met for all standards and the reviewer must use professional judgement on the severity of the problem and its effect on the final results

VI COLUMN PERFORMANCE RESOLUTION CHECK (Method I6I3B amp 8290A)

Date ID

Was the chromatographic resolution of the TCDDTCDF isomers and the in the CC3 or CS3 solution far DB-5 columns calculated for each 12 hour period ^mdash^^

Valley -TCDD -TCDD (QC Limit s 25)

Valley -TCDF -TCDF (QC Limit s 50)

For DB-225 columns

Valley -TCDD -TCDD (QC Limit lt 25)

Valley -TCDF -TCDF (QC Limit i 50)

ACTIONS

A If the GC resolution criteria do not meet specifications the positive hits will be qualified as J All tetras and hexas (for both dioxin and furans) will be qualified The heptas are not believed to be affected OCDD and OCDF are not affected as there is only one isomer in each group No action is taken for non-detects

B The criteria for chromatographic resolution must be met for all standards and the reviewer must use professional judgement on the severity of the problem and its effect on the final results

Areas I and II - Mohawk Tannery Site Nashua New Hampshire

bdquobdquo

Dear Mr Splendore

On behalf of Brownfields Recovery Corporation and Envnonmental Reclamation Inc GeoSyntec Consultants Inc (GeoSyntec) has prepared the attached data report for the prehmmaiy waste characterization of sludge in Areas I and II at the former Mohawk Tannery property located at 11 Warsaw Avenue in Nashua New Hampshire (the Site) Information contained in this report was based on the work conducted in accordance with GeoSyntec s scope of work dated October 16 2000 which was reviewed and approved by the New Hampshire Department of Environmental Services and U S EPA Region 1

The findings of this study based on that Toxicity Characteristic Leaching Procedure (TCLP) hazardous characteristics analyses of the sludge samples collected in Areas I and II indicated that the sludge is not characteristically hazardous as defined m 40 CFR 261 20 Additionally the results of the sample analyses did not identify any of the following characteristics ignitabihty corrosivity reactivity or toxicity

Please feel free to contact the undersigned for any questions

VI COLUMN PERFORMANCE RESOLUTION CHECK (Method I6I3B amp 8290A)

Date ID

Was the chromatographic resolution of the TCDDTCDF isomers and the in the CC3 or CS3 solution far DB-5 columns calculated for each 12 hour period ^mdash^^

Valley -TCDD -TCDD (QC Limit s 25)

Valley -TCDF -TCDF (QC Limit s 50)

For DB-225 columns

Valley -TCDD -TCDD (QC Limit lt 25)

Valley -TCDF -TCDF (QC Limit i 50)

ACTIONS

A If the GC resolution criteria do not meet specifications the positive hits will be qualified as J All tetras and hexas (for both dioxin and furans) will be qualified The heptas are not believed to be affected OCDD and OCDF are not affected as there is only one isomer in each group No action is taken for non-detects

B The criteria for chromatographic resolution must be met for all standards and the reviewer must use professional judgement on the severity of the problem and its effect on the final results

Dear Mr Splendore

On behalf of Brownfields Recovery Corporation and Envnonmental Reclamation Inc GeoSyntec Consultants Inc (GeoSyntec) has prepared the attached data report for the prehmmaiy waste characterization of sludge in Areas I and II at the former Mohawk Tannery property located at 11 Warsaw Avenue in Nashua New Hampshire (the Site) Information contained in this report was based on the work conducted in accordance with GeoSyntec s scope of work dated October 16 2000 which was reviewed and approved by the New Hampshire Department of Environmental Services and U S EPA Region 1

The findings of this study based on that Toxicity Characteristic Leaching Procedure (TCLP) hazardous characteristics analyses of the sludge samples collected in Areas I and II indicated that the sludge is not characteristically hazardous as defined m 40 CFR 261 20 Additionally the results of the sample analyses did not identify any of the following characteristics ignitabihty corrosivity reactivity or toxicity

1 INTRODUCTION

On behalf of Environmental Reclamation Inc (ERI) and Brownfields Recovery Corporation (BRC) GeoSyntec Consultants Inc (GeoSyntec) has conducted the following Preliminary Sludge Characterization Investigation (PSCI) for the Mohawk Tannery (the Site) in Nashua New Hampshire The work was conducted in accordance with our scope of work dated October 2000 which was approved by the NHDES and USEPA and is attached as Appendix A

11 Background

111 Site History and Description

The Mohawk Tannery (formerly known as the Granite State Tannery) is located on a 30-acre parcel at 11 Warsaw Avenue in the City of Nashua Hillsborough County New Hampshire (see Figure 1 for Area Location Map) The facility produced tanned hides for leather products between 1924 and 1984 and is currently inactive1 The property is bordered by the Nashua River to the west by residences to the southeast and east and undeveloped areas to the north and southwest

Sub-areas of the Site referred to as Areas I through VII have been identified in previous studies as areas containing sludge wastes created during the tanning process Three Source zones were identified at the Site in the Hazard Ranking System (HRS) evaluation conducted by USEPA in 2000 Source 1 is comprised of Areas I and n Source 2 is defined as the Secondary Clarifier Tank and Source 3 is comprised of the Areas IH through VH

Areas I and n are aligned parallel to the Nashua River and are classified by the USEPA as surface impoundments2 Both areas received wastewater from the hide preshytanning process previously located at the main facility After removal of solids through a screening process the impoundments received pre-treated wastewater for additional sedimentation and eventual discharge of the supernatant to the Nashua River The

secondary clarifier unit was brought on line in 1981 after the completion of a new treatment facility Alkaline and acid waste streams were combined and routed to the primary clarifier discharged to Area I for sedimentation and then to the secondary clarifier prior to discharge to the Nashua River Sludge and liquid waste are currently being addressed in Source Area 2 under a Time Critical Removal Action by the USEPA Areas HI IV V and VTI are former disposal pits used for piling sludge dredged from Areas I and n Area VI was historically used as a series of settling basins for acid waste streams prior to discharge to the Nashua River These areas received sludge waste until the early 1960s when the new treatment process was built Areas n ffl IV V and VI have since been covered with fill Records indicate that Areas n and V have been covered with logs as well as a 1-2 foot thick layer of sand3

The EPA has ranked the Site and determined that the Site is eligible for inclusion on the National Priorities List (NPL) but the Site has not yet been listed

112 Regional Hydrogeology

Hydrogeologjc studies of the Nashua area show that surficial geology consists of glacial till deltaic deposits and recent alluvial terrace deposits These deposits are underlain by the Merrimack Group (bedrock) consisting of the Early Devonian Berwick Formation and Eliot Formation although the stratigraphic sequence of the two formations is uncertain The Berwick Formation occurring beneath the Site and in a four-mile radius trends southwest-northeast and is composed of metasedimentary phyUites granulites gneisses and schists with intrusions of granodiorite and binary granite The Site is located in the general area of the Merrimack trough which trends northeast and outlets eventually to the Merrimack River4

113 Site Hydrogeology

1131 Unconsolidated Deposits Aquifer

The unconsolidated deposits range from less than five feet thick on the eastern portion of the Site to approximately 80 feet thick to the west Depth to groundwater at the Site typically ranges from 4 to 31 feet below ground surface (bgs) and flows in a generally south-southwest direction The surficial deposits in the western portion of the Site along the Nashua River terrace consists of recent alluvium which continues to receive deposition during flooding Artificial fill materials have replaced the alluvium in select locations such as in Areas I and n

1132 Bedrock Aquifer

Bedrock underlying the Site is moderately to highly fractured The primary fracture system trends northeast parallel to the Merrimack Trough Bedrock ranges from less than five to 80 feet bgs across the facility property generally sloping in a south-southeastern direction

2 OBJECTIVE

The goal of the PSCI was to collect preliminary waste characterization data for the sludge present in Areas I and n at the Site The purpose of collecting these data was to gain an increased understanding of the waste characteristics of the sludge which are required to determine disposal options GeoSyntec achieved the objective of the PSCI with the scope of work outlined below and detailed in the following sections

31 Site Walkover

GeoSyntec performed a reconnaissance visit to document the current conditions of the Site The walkover focused on the feasibility of sampling various locations and the equipment requirements to obtain the appropriate samples Areas I and II were easily recognized during the Site walkover Area 1 consisted of an embanked area with approximately 1-2 feet of standing water similar to that presented the aerial photo in Figure 1 Area n also consisted of an embanked area but was free of standing water at the time of the walkover However dense vegetation observed in the central area of the lagoon is indicative of wet soils The sample locations chosen in Area I and n are presented in Figure 1 Prior to field activities sample locations were located for municipal and private utility clearance GeoSyntec developed sampling techniques for the collection of representative samples from the complete sludge thickness in Areas I and n These methods are further discussed in Section 322 and 323

32 Plan Development

The development of Site-specific plans was undertaken subsequent to the Site visit Plans developed included a Health and Safety Plan (HASP) a Sampling and Analysis Plan (SAP) and a Quality Assurance Project Plan (QAPP) The SAP and QAPP were combined under single cover for this project Development of the plans relied on previous work conducted by GZA GeoEnvironmental Inc (GZA) and information gained during GeoSyntecs Site visit Data collected during GZAs 1985 investigations were evaluated and verified by the current conditions observed at the Site The HASP conformed to the Occupational Health and Safety (OSHA) requirements presented in 29 CFR Part 1910 and applicable NHDEP hazardous waste regulations The SAP detailed the sample collection and analytical methodologies to be implemented during these tasks Quality assurance

objectives were also defined to ensure representative environmental samples were acquired and analyzed (GeoSyntec 2000) The sample locations and collection procedures are described in detail below

33 Sample Collection

331 Sampling Locations

Samples of sludge material were collected from Areas I and El The sludge material located in Areas I and n is assumed representative of the waste contained in Areas HI through VII This assumption is based on the understanding that the property has operated primarily as a tannery and other waste streams were not generated Further the sludge disposal locations in Areas HI through Vn were primarily derived from the dredging of Areas I and n The sludge disposal areas (Areas in through VII) were not sampled as part of this field effort Past sludge volume estimates prepared by others (GZA and NHDES) have indicated the majority of the sludge to be contained within Areas I and n

Sludge samples were collected at three locations in Area I using a boat and excavator and five locations in Area n using an excavator The sludge sample collection method was consistent with the ASTM standard D-4823 The sample collection locations are presented in Figure 1

332 Sample Collection Methods and Analysis

3 321 Area I Sample Collection

Sludge core samples were collected from three locations in Area I and identified as AR01-SS01 through AR01-SS03 (see Figure 1) The sampler consisted of dedicated ten-foot sections of two- and four-inch diameter schedule 40 PVC pipe At each location two cores were obtained to ensure homogenization and representativeness of the sludge material The pipe was manually driven into the sludge until refusal was encountered which ranged from approximately 6 to 9 feet below the sludge surface Table 31 presents the core specific sampling data From field observations refusal resulted from encountering native soil beneath the sludge which was confirmed upon retrieval Prior to retrieval of the sampler a sealed top cap was installed and a vacuum was applied to ensure sample recovery The sampler was extracted from the sludge using one of two methods

01R2901 5 010110

GeoSyntec Consultants

At a location where the excavator drove the sampler (AR01-SS03) the sampler was extracted using the excavator to pull back on the pipe with a slip yoke The sludge samples acquired using the boat (AR01-SS01 and AR01-SS02) were extracted by rotating and pulling back the sampler by hand The sampler was then split lengthwise for stratigraphic observation and sub-sample collection The Standard Operating Procedure (SOP) for sludge sampling and field headspace analyses of sludge samples were provided in the SAPQAPP (GeoSyntec 2000)

The sludge samples from Area I were observed to be homogeneous with depth and location throughout the area Sludge samples were characterized as a saturated black clayey material with hair and humus A strong hydrogen sulfide odor was noted The sludge from Area I exhibited high percent moisture content ranging from 72 to 82 percent by mass and decreasing with depth A Mini-RAE multimeter equipped with photoionization detector (PED) and 106electron volt (eV) lamp and additional sensors for gases including hydrogen sulfide was used for field headspace analyses of discreet sludge samples from three locations Field screening results indicated an increase in concentrations of total VOCs with depth (see Table 31) Hydrogen sulfide concentrations were fairly consistent and were above the calibration range of the instrument Collection of sludge samples for Toxicity Characteristic Leaching Procedure (TCLP) testing for VOC fractions were obtained from the sample interval of the core which exhibited the median headspace reading (AR01-SS01 through AR01-SS03) The core was then homogenized for the remaining TCLP analytes which included semi-VOCs pesticides and RCRA 8 metals and for mass analyses of polychlorinated biphenyls (PCBs) and dioxindibenzofurans Additionally each homogenized sample was analyzed for reactivity (reactive sulfide and cyanide) ignitability and corrosivity (pH) The remaining material was combined with subsequent sample locations within Area I for the collection of a composite sample (AR01-COMP) for mass analysis for pentachlorophenol and chromium speciation (ie total chromium versus hexavalent chromium) a duplicate sample (AR01shyCOMPD) was also collected for QAQC protocols

3322 Area n Sample Collection

Sludge samples were collected from five locations in Area n Demeter Construction services of Everett Massachusetts provided a 315 Caterpillar excavator for the

advancement of test pits in Area n The locations of the test pits (AR02-TP01 through AR02-TP05) are provided in Figure 1

Locations AR02-TP01 and AR02-TP02 were located on the northeast and northwest comers of Area n respectively Both test pits revealed similar subsurface features an upper sand unit from ground surface to approximately 6 feet bgs a lower sludge unit from 6 to 11 feet and a base unit of logs which were installed as a closure technique for Area II Remnants of what appeared to be a metal drum was observed in AR02-TP01 Samples in these two locations were collected with a hand auger from the impacted material of the lower unit The sludge material was a mix of gray colored sludge with varying amounts of sand and hair A moderate hydrogen sulfide odor was noted Field headspace screening results did not indicate the presence of VOCs at these locations Hydrogen sulfide concentrations were consistent and ranged between background and 10 ppm

Locations AR02-TP03 through AR02-TP05 exhibited similar waste profiles In these locations sludge material was observed from 15 to 12 feet BGS (see Table 32) The sludge material had a similar matrix to the samples collected in Area I The sludge could be distinguished as two separate units an upper black unit and a lower gray unit The matrix of the two units was similar consisting of a mixture of clay and sand with varying amounts of humus and hair Grain size decreased with depth Decomposed hides were observed in the sludge at AR02-TP03

The moisture content in Area n exhibited a range of 354 to 557 percent by mass significantly lower than Area I

Sludge samples submitted for TCLP VOCs analyses (AR02-TP01 through AR02shyTP05) were collected from a hand auger at a discreet depth interval The remaining sludge sample was then homogenized for the additional TCLP analytes which included semi-VOCs pesticides and RCRA 8 metals and for mass analyses including polychlorinated biphenyls (PCBs) and dioxindibenzofurans Additionally each homogenized sample was analyzed for reactivity (reactive sulfide and cyanide) ignitability and corrosivity (pH) A composite sample consisting of the remaining sludge material from locations AR-02-TP-01 through AR-02-TP03 was combined (AR02-COMP) and submitted for mass analysis of pentachlorophenol and chromium speciation

342 Pentachlorophenol DioxinDibenzofuran and Chromium Speciation Analyses

Standard QAQC measures were observed in the collection procedures for these samples Standard operating procedures for sample labeling handling transport and tracking through chain-of-custody records were followed for these samples

One duplicate sample and MSMSD was collected for total pentachlorophenol total chromium and hexavalent chromium The laboratory MSMSD analysis was performed by the laboratory to confirm detected concentrations of analytes in the samples

Additional samples not included in the SAP were collected for total chromium and dioxindibenzofuran analysis Samples of the fill material encountered above the sludge in Area n were collected and analyzed for total chromium by Method SW6010B The results are discussed in Section 422 Additional sludge samples for dioxindibenzofuran analyses were collected from the locations AR01-SS01 through AR01-SS03 and AR02-TP01 through AR02-TP05 Originally the SAP only required the collection of two dioxindibenzofurans from composite samples of Area I and n

4 ANALYTICAL TESTING RESULTS

41 Areas I and II

411 TCLP and Mass Analyses

The results of TCLP and mass testing data for sludge samples collected from Areas I and n are summarized in Table 41

None of the sludge samples collected from Areas I or n were determined to be hazardous by characteristics Chromium was the only RCRA 8 metal detected in the TCLP leachate Concentrations of TCLP chromium were detected between 011 to 34 mgL or expressed as parts per million (ppm) in the TCLP extract from sludge samples collected in Areas I and n The maximum allowable leachate concentration for TCLP chromium is 50 mgL Some of the listed TCLP SVOCs detected in sludge samples included cresols pentachlorophenol 245-trichlorophenol 14-dichlorobenzene and 4-methylphenol The TCLP concentrations of these SVOCs were at least one order of magnitude less than the maximum leachate concentration of contaminants for the waste characteristic One VOC 14 dichlorobenzene was detected at a maximum concentration of 0088 mgL which is two orders of magnitude below the maximum leachate concentration for the waste characteristic TCLP Pesticides and total PCBs were not detected in sludge samples collected in Areas I and n The laboratory data sheets and case narratives are attached in Appendix A

412 DioxinDibenzofuran Pentachlorophenol and Chromium Speciation Analyses

Results of dioxindibenzofuran pentachlorophenol and total chromium species are presented in Table 42 Concentrations of these constituents in several samples were outside of the linear range of the specific analysis or saturated the detector due to the properties of the sludge resulting in a qualified data set The highest detections were from the hexa- (6) to octa- (8) chlorinated dioxins and dibenzofurans such as total hexa-dioxins

01R2901 10 010110

GeoSyntec Consultants

and dibenzofurans total septa-dioxins and dibenzoflirans and octa-dioxins (OCDD) and dibenzofurans (OCDF) The less chlorinated species were detected at lower concentrations including the tetra- (4) and penta- (5)- dioxins and dibenzofurans that are regulated at 0001 mgKg (ppm) pursuant to 40 CFR 268 Land Disposal Restrictions The laboratory data sheets and a case narrative are provided in Appendix B

The detection of several SVOCs (Table 41) in the composite sludge samples and the elevated concentrations in the dioxindibenzofuran analyses confirm that our samples exhibited similar constituents to the previous work at the Site by others The concentrations observed in the current samples are orders of magnitude less than what was observed in sludge samples collected during GZAs 1985 study however these samples were composited over larger areas

The results of the total and hexavalent chromium analyses are presented in Table 43 These samples were collected then spilt and analyzed for total chromium and hexavalent chromium The comparison of results is also presented in Table 42 The results confirm that the chromium in the sludge is predominantly trivalent chromium

Total chromium concentrations detected in samples collected above the sludge in Area H ranged from 51 ppm at AR-02-TP01 to 1800 ppm at AR02-TP-05

5 CONCLUSIONS AND RECOMENDATIONS

The PSCI was completed as an initial investigation of the disposal options for sludge present at the Site The data collected for TCLP and hazardous characteristics analyses indicated that the sludge in Areas I and n is not characteristically hazardous as defined in 40 CFR 26120 The results of the sample analyses did not identify any of the following characteristics ignitability corrosivity reactivity or toxicity

Although the presence of other analytes in the sludge (ie dioxins and dibenzofurans) does not render the waste hazardous by characteristics the sludge could potentially be considered an F series listed hazardous waste dependant on specific knowledge of its source Specifically a waste is considered F021 waste if it is from the production or manufacturing use of pentachlorophenol or of intermediates used to produce its

01R2901 11 010110

GeoSyntec Consultants

derivatives However based on our knowledge of waste generated at the Site and usage of tanning chemicals containing pentachlorophenol the source is unknown and as such would not meet the definition of F021 If based on further knowledge the waste is determined to be F021 listed hazardous waste the presence of dioxins at concentrations above Land Disposal Restriction limits as set forth in 40 CFR 26831 will likely limit local disposal options

Based on the evaluation of the waste characteristic data conducted pursuant to 40 CFR 26120 for RCRA classification of waste materials its waste characteristics as measured in this study as well as other characteristics such as the need for solidification of sludge for transport the sludge could be transported to and disposed of at a USEPA and NHDES approved local landfill

Sample Collection and Analysis

Samples of sludge material will be collected from Lagoon Areas I and II The sludge material located in Areas I and n will be assumed to be representative of the waste contained in all areas This assumption is based on the belief that the property has operated primarily as a tannery and other waste streams are not suspected Further the sludge disposal locations in Areas III through VII were derived from the dredging of Lagoons I and II The sludge disposal areas (Areas HI through VII) will not be sampled as part of this field effort however would be included in subsequent efforts if disposal options are favorable Please note that past estimates by others have indicated the majority of the sludge to be within Areas I and II

Sludge samples will be collected from up to three locations in Area I and up to five locations in Area II The samples will be acquired from a boat in the Area I and from test pits in Area II The sludge sample collection method is consistent with the ASTM standard D-4823 The precise sample collection locations will be determined by the GeoSyntec field technician and will depend on Site conditions on that day

Area I Sample Collection

Sludge core samples will be collected from up to three locations from Area I The sampler will consist of ten-foot sections of disposable two-inch diameter schedule 40 PVC pipe The pipe will be fitted with a sample catch and will be driven into the lagoon sludge until refusal Additional sections of pipe will be added if necessary From field observations we believe refusal will result from the intersection of the sampler with native soil The sampler will then be retrieved and split lengthwise for stratigraphic observation and sample collection Samples for headspace screening and VOCs will be collected at discrete intervals (eg every 2 feet) from the length of the core The basis for the selection to determine which VOC sample will be sent for laboratory analysis will be based on the headspace screening results Our Standard Operation Procedure (SOP) for the analysis of headspace samples is provided in the attached Sampling and Analysis Plan SAP The associated VOC sample with the

3 Objectives The goal of this QAPP SAP is to outline the methods and quality controls that will

be implemented during the preliminary chemical characterization sampling of the sludge remaining in disposal lagoons (Areas I and II) at the Site The purpose of collecting these data is to gain an increased understanding of the sludge characteristics which are needed to determine disposal options This sampling event is a preliminary phase to develop a privately funded cleanup alternative for the Site

The work to be performed under this QAPP SAP is limited to the waste characterization sampling The data is not intended for risk assessment purposes and therefore is not subject to rigorous QAQC requirements The sample methods analytical methods and quality assurance objectives are outlined in the following text as well as general site conditions To the extent possible we have included methodologies accepted and practiced by the USEPA

31 Data Quality Objectives Valid data of known and documented quality are needed to address the objectives

listed in this QAPPSAP The data will be validated according to the following parameters

311 Analytical and Field Measurement Data The Data Quality Objectives (DQOs) for the analytical data collected under the

direction of this QAPPSAP are defined through the primary data quality indicators (DQIs) precision bias accuracy representativeness completeness and comparability (sometimes referred to as PARCC criteria) Appendix A defines the statistics that will be used to evaluate the DQIs

3111 Precision

Precision is a measure of agreement among replicate measurements of the same property under prescribed similar conditions Precision will be calculated as the relative percent difference (RPD) for laboratory duplicates (including matrix spikematrix spike duplicates or MSMSD) and field duplicates Field duplicates will be used for field parameters The frequency and applicability of these duplicates are discussed in Section 72

4 Background 41 Site History and Description

The Mohawk Tannery (formerly known as the Granite State Tannery) is located on a 30-acre parcel at 11 Warsaw Avenue in the City of Nashua Hillsborough County New Hampshire (See Figure 1 for Area Location Map) The facility produced tanned hides for leather products between 1924 and 1984 and is currently inactive1 The property is bordered by the Nashua River to the west by residences to the southeast and east and undeveloped areas to the north and southwest

Areas I through VII have been identified in previous studies as areas containing sludge wastes created during the tanning process These areas have been further divided into three Source zones Source 1 is comprised of Areas I and II Source 2 is defined as the Secondary Clarifier Tank from the former treatment system and Source 3 is comprised of the Areas III through VII

Areas I and II are located parallel to the Nashua River and are classified by the United States Environmental Protection Agency (USEPA) as surface impoundments Both areas were used to receive effluents from the hide pre-tanning preparation area of the main facility After removal of solids through a screening process the impoundments received the effluent for additional sedimentation and eventual discharge to the Nashua River Areas III IV and VI are former disposal pits used for piling sludge dredged from Areas I and II These areas received sludge waste until the early 1960s when a new treatment plant was built Areas II III IV V VI and VII have since been covered with fill Records indicate that Areas II and V have been covered with logs as well as a 1-2 foot thick layer of sand2

Sludge and liquid waste are currently being addressed in Source Area 2 under a Time Critical Removal Action by the USEPA The EPA has ranked the Site and determined that the Site is eligible for inclusion on the National Priorities List (NPL) but the Site has not yet been finalized on the NPL

42 Regional Hvdrogeology Hydrogeologic studies of the Nashua area show that surficial geology consists of

glacial till lacustrine delta deposits and recent alluvial terrace deposits These deposits

5 Sampling Locations Samples of sludge material will be collected from lagoon Areas I and II The

sludge material located in Areas I and II will be assumed to be representative of the waste contained in all areas This assumption is based on the belief that the property has operated primarily as a tannery and other waste streams are not suspected Further the sludge disposal locations in Areas in through VII were derived from the dredging of lagoons I and II The sludge disposal areas (Areas III through VII) will not be sampled as part of this field effort however would be included in subsequent efforts if disposal options are favorable Please note that past estimates by others have indicated the majority of the sludge to be within Areas I and D

Sludge samples will be collected from at least three locations in Area I and at least five locations in Area II The samples will be acquired from a boat and an excavator in Area I and from test pits in Area n The sludge sample collection method is consistent with the ASTM standard D-4823 The precise sample collection locations will be determined by the GeoSyntec field technician and will depend on Site conditions on that day

Sample Handling and Custody Requirements Indelible ink pens and waterproof labels will be used to label sample containers

All samples will be labeled with the following information

bull project name bull unique location specific sample identification bull date and time of collection bull analysis to be performed bull preservation chemical (if used) bull initials of person(s) collecting sample

If samples are to be shipped to the laboratory sample containers will be individually wrapped in plastic bubble wrap and secured with rubber bands A bed of bubble wrap should line the bottom of the cooler and samples should be spaced evenly on top of this bed Ice or reusable ice packs will be evenly distributed between the samples along with vermiculite or additional bubble wrap Bubble wrap should be set on top of the samples to fill the remaining balance of the cooler A detailed description of packaging and shipment procedures are provided in Attachment B

Complete all chain of custody (COC) documentation with complete information for each sample Double check that the COC corresponds with the actual samples in the cooler Sign the COC form including the date and time before relinquishing custody of the cooler and samples Remove the appropriate copy from the COC or make copies as necessary and retain with other field notes Place the original and remaining copies in a zip-lock bag to prevent water damage from melting ice Close the cooler or container If cooler is to transported to the lab by a third party secure signed COC seals over the lid of the cooler such that they span the lid and the side it contacts Transparent tape should be wrapped around the cooler over the COC seals as to secure the lid to the cooler

Upon receiving the samples the laboratory sample custodian will inspect the condition of the custody seal and samples measure the cooler temperature and compare the information on the sample labels against the chain-of-custody forms The date and time of shipment receipt by laboratory and name and signature of person receiving samples will be recorded by the laboratory on the chain-of-custody form The following

Decontamin ation Cleaning of non-disposable excavation equipment field sampling and measuring

equipment and personal protective equipment (PPE) will be performed to minimize the potential for cross-contamination between sample locations and samples and to minimize the potential for exposure of workers to Site-related chemicals Procedures for cleaning of PPE will be described in the Site-specific Health and Safety Plan Excavation equipment will be cleaned in a specified centralized cleaning area at the Site

Sample equipment shall be decontaminated between sampling locations or boreholes They shall be emptied of excess sample into appropriate containers as project criteria specify Samplers shall then be scrubbed with a brush in a clean waternon-phosphate soap solution to remove adhering soil material The samplers shall then be rinsed in clean water Samplers may also be cleaned utilizing steam Other cleansing agents or techniques may be required as outlined by any project-specific criteria and should be followed accordingly

With the exception of dioxindibenzofuran testing which will be performed by Axys Analytical (Axys) in Vancouver BC Canada we plan to use AMRO Environmental Laboratory Corporation for the analyses of the sludge samples which is a state certified laboratory We have provided Axys and AMROs Quality Systems Manuals as Attachment C

7J Quality Control Requirements This section describes the field and laboratory QC sample requirements for the

laboratory data

731 Trip Blanks Trip blanks (also referred to as field blanks) are sample bottles containing analyteshy

free de-ionized water prepared at the contract laboratory and stored and shipped with the samples The trip blanks will not be opened in the field Care will be taken to ensure that the trip blank and sample bottles originate from the same shipment of bottles from the laboratory Information obtained from the trip blank analyses will be used to determine whether and to what extent sample handling and analysis has introduced positive bias to the sample results Trip blanks (and the associated sample batch) are acceptable if they contain analyte concentrations less than the reporting limit (or not greater than method blank results if method blanks contain detectable levels of analytes)

732 MSMSD Samples for MSMSD analyses will be collected by field personnel prepared by

laboratory personnel and analyzed to evaluate the effects of the sample matrix on the analytical results (ie assess bias) For the MSMSD sample three times the regular sample volume will be collected using the same sampling procedures for regular

SAPQAPPdoc 14 001020

bull Sample handling procedures documented on the chain-of-custody forms field records and laboratory case narrative match the planned procedures

bull Field QC was conducted as planned and meets the acceptance criteria and bull Electronic data are free from transcription errors

Deviations from the QAPPSAP are to be reported If the data fails to meet the criteria listed above they will be flagged and discussed with management to determine if the data point will be rejected and re-sampling done

742 Data Validation Data validation will be performed to verify the qualitative and quantitative reliability of the data Water VOC data will be subject to validation as follows

1 Any data and sampling information requiring transcription from the laboratory reports and field forms into data summary tables will be verified by checking the entries against the laboratory reports and field forms

2 A detailed review of the sampling records sample results and QAQC information (including field QC samples) will be undertaken Sample collection records chain-ofshycustody holding times dilution factors analytical QLs and laboratory and field QC sample records will be reviewed to evaluate whether the DQOs (described in Section 31 of this QAPPSAP) have been met Tier II Reporting

3 The results shall be compared with historic Site data andor expected results to identify any potential anomalous results or errors

4 Data qualification and response actions will be implemented for data not meeting the QA objectives

5 An overall assessment of the data quality will be prepared which addresses the QA objectives for the data set and notes any data limitations anomalies or suspected errors

Detailed procedures to be implemented during validation of the data will be developed in accordance with EPA guidelines

8 Documentation and Records This section specifies the documentation requirements for project records and the

process for ensuring that the most current copy of the QAPPSAP is available

SUBJ Review of the Preliminary Sludge Characterization Investigation Submittal (January 2001) for the Mohawk Tannery Site

FROM Neil Handler RPM

TO Andrew Beliveau Quality Assurance Chemist

Attached to this memorandum you will find a copy of the Preliminary Sludge Characterization Investigation Submittal (January 2001) for work associated with the investigation of the disposal lagoons located at the Mohawk Tannery Site in Nashua New Hampshire As we discussed previously the investigative work was performed by a private developer under the auspices of the State of New Hampshire Voluntary Cleanup Program Therefore the QAQC requirements put in place may not necessarily be equivalent to what EPA would require for such data gathering

I am interested in using as much of this data as possible for the EECA which we will be starting shortly I am especially interested in your thoughts about the dioxinfuran data gathered and would appreciate your help in evaluating the usefulness of this data It is my understanding that sufficient QAQC information is contained hi the report which should allow for the data validation of the dioxinfuran data I would appreciate your help hi reviewing the above document and confirming the usefulness of the data within a month of your receipt of this memorandum (if possible) Please feel free to contact me if there are any questions or you anticipate any problems with the proposed schedule Thank you in advance for your help

SUBJ Review of the Preliminary Sludge Characterization Investigation Submittal (January 2001) for the Mohawk Tannery Site

FROM Neil Handler RPM

TO Andrew Beliveau Quality Assurance Chemist

Attached to this memorandum you will find a copy of the Preliminary Sludge Characterization Investigation Submittal (January 2001) for work associated with the investigation of the disposal lagoons located at the Mohawk Tannery Site in Nashua New Hampshire As we discussed previously the investigative work was performed by a private developer under the auspices of the State of New Hampshire Voluntary Cleanup Program Therefore the QAQC requirements put in place may not necessarily be equivalent to what EPA would require for such data gathering

I am interested in using as much of this data as possible for the EECA which we will be starting shortly I am especially interested in your thoughts about the dioxinfuran data gathered and would appreciate your help in evaluating the usefulness of this data It is my understanding that sufficient QAQC information is contained hi the report which should allow for the data validation of the dioxinfuran data I would appreciate your help hi reviewing the above document and confirming the usefulness of the data within a month of your receipt of this memorandum (if possible) Please feel free to contact me if there are any questions or you anticipate any problems with the proposed schedule Thank you in advance for your help

Neil I need to clarify my previous message

1) The problem is that the lab did not submit a form called Axys Sample Receiving Record for the samples that they received on 102500 where they should have discussed on the form the two samples that were received broken They should have discussed this in their narrative also They did send a form for the samples that they received on 11400 I will FAX over a copy of what the form looks like i e the 11400 one

2) The lab did analyze all the samples that they received that were not broken So we are all set on that score

Sorry for the confusion Please call me and we can go over this to make sure we are all clear

Attached to this memorandum you will find a copy of the Preliminary Sludge Characterization Investigation Submittal (January 2001) for work associated with the investigation of the disposal lagoons located at the Mohawk Tannery Site in Nashua New Hampshire As we discussed previously the investigative work was performed by a private developer under the auspices of the State of New Hampshire Voluntary Cleanup Program Therefore the QAQC requirements put in place may not necessarily be equivalent to what EPA would require for such data gathering

I am interested in using as much of this data as possible for the EECA which we will be starting shortly I am especially interested in your thoughts about the dioxinfuran data gathered and would appreciate your help in evaluating the usefulness of this data It is my understanding that sufficient QAQC information is contained hi the report which should allow for the data validation of the dioxinfuran data I would appreciate your help hi reviewing the above document and confirming the usefulness of the data within a month of your receipt of this memorandum (if possible) Please feel free to contact me if there are any questions or you anticipate any problems with the proposed schedule Thank you in advance for your help
