Elm Jefferson City, Missouri 65101 RE: Annual Groundwater and Sub-Slab Vapor Monitoring Report Former Sporlan Valve Company Plant No. 1 611 East Seventh Street Washington, Missouri ENVIRON Project No. 19-15953A Dear Ms. Surber: ENVIRON International Corporation (ENVIRON), on behalf of Sporlan Valve Company (Sporlan), is submitting the enclosed report documenting the recent annual groundwater and sub-slab vapor monitoring event performed during February 2015 at the former Sporlan Valve Company Plant No. 1 facility located at 611 East Seventh Street in Washington, Missouri (site). As formally acknowledged in your May 1, 2014 letter, Sporlan is withdrawn from the Brownfields/Voluntary Cleanup Program (B/VCP). Although annual monitoring will be performed as described below, Sporlan is currently withdrawn from the B/VCP. Accordingly, Sporlan does not expect to receive a bill for any oversight costs from MDNR. Sporlan currently plans to continue to perform annual groundwater and sub-slab vapor monitoring to continue to monitor groundwater conditions at onsite and offsite locations, and monitor sub-slab vapor conditions at offsite locations.

April 15, 2015 Ms. Jennifer Surber Environmental Specialist Brownfields/Voluntary Cleanup Section Hazardous Waste Program Missouri Department of Natural Resources 1738 E. Elm Jefferson City, Missouri 65101 RE: Annual Groundwater and Sub-Slab Vapor Monitoring Report Former Sporlan Valve Company Plant No. 1 611 East Seventh Street Washington, Missouri Dear Ms. Surber: ENVIRON International Corporation (ENVIRON), on behalf of Sporlan Valve Company, is submitting this report documenting recent groundwater and sub-slab vapor monitoring performed during February 2015 at the former Sporlan Valve Company Plant No. 1 facility located at 611 East Seventh Street in Washington, Missouri (site). In accordance with the May 1, 2014, correspondence from the Missouri Department of Natural Resources (MDNR) Brownfield Voluntary Cleanup Program (B/VCP), we understand this annual monitoring report will be accepted by the MDNR B/VCP without review or comment since the site status has been changed to “inactive.” The February 2015 activities consisted of a groundwater monitoring event, including the collection of samples from onsite and offsite monitoring wells and a sub-slab vapor sampling event at three properties located along the south side of East Seventh Street. This annual monitoring event was performed as described in our November 27, 2013, correspondence and the specific monitoring activities were conducted in accordance with the Work Plan for Groundwater Monitoring, Sub-slab Vapor Monitoring, Bedrock Groundwater Assessment and Tier 2 Risk Assessment submitted to the MDNR B/VCP on December 6, 2011 and approved on February 22, 2012.

SCOPE OF WORK Groundwater Monitoring Groundwater sampling activities were performed February 9-13, 2015. Depth-to-water measurements were taken and recorded from all wells prior to purging. No groundwater was present in MW-1 during this sampling event, as has been the case for most of the sampling events (nine of 12 events) over the last seven years and nine months (MW-1 was also dry during the MW-1 test pit investigation performed on March 14, 2012). Prior to sampling, MW-2 through MW-9 were purged a minimum of three well volumes with a peristaltic pump using low-flow purging and sampling procedures. MW-10 through MW-12 were purged a minimum of

three well volumes using 1.6 inch diameter disposable bailers (as the water level in these wells was too deep to allow pumping with a peristaltic pump after purging commenced due to slow re-charge). A flow-through cell and multiple-parameter water quality meter were used to measure water quality parameters (pH, conductivity, dissolved oxygen, oxidation reduction potential and temperature) during purging of all eleven wells. Groundwater samples were submitted to Teklab, Inc. (Collinsville, IL) for analysis of total volatile organic compounds (VOCs) using EPA Method 8260. During transit to the laboratory, the 40 milliliter vials containing the groundwater sample for MW-10 were broken and no sample representing MW-10 was initially provided to the laboratory. MW-10 was subsequently sampled on February 20, 2015. Purge water was containerized in a 65 gallon polyethylene tank and five gallon polyethylene buckets, transported to the City of Washington wastewater treatment plant and disposed in the sanitary sewer located at the wastewater treatment plant. Approval for this discharge was granted by Mr. John Zimmerman with the city of Washington Wastewater Department (see Appendix A for a copy of the approved Hauled Wastewater Permit). Sub-Slab Vapor Investigation On February 9, 2015, a total of four investigative sub-slab vapor samples were collected. Sub-slab vapor samples were collected from sampling ports previously installed within the basements of houses located at 604 East Seventh Street and 612 East Seventh Street along the south side of East Seventh Street. Two new sampling ports were installed at 622 East Seventh Street on February 11, 2015, because the previously installed ports had been covered by epoxy cement as part of a basement remodeling effort, resulting in one additional investigative sample collected within the basement of this house on February 12, 2015. The southern sampling port was damaged during sampling on February 12, 2015 and a new sampling port was installed on February 13, 2015 and was subsequently sampled on February 23, 2015. In addition to the six investigative samples, one duplicate sub-slab vapor sample was collected at the eastern sampling port at the 604 East Seventh Street property using a sampling "tee" manifold provided by the analytical laboratory (Eurofins Air Toxics, Inc.). The owner of the property at 616 East Seventh Street did not grant access for sampling during this event.1 The exterior temperature while sub-slab vapor sampling was performed ranged from 10ºF to 40ºF. Due to the cold weather, the respective homes’ heating systems were operating during sample collection. Sub-slab vapor samples were collected in accordance with the approved Work Plan (December 2011), with two modifications as noted below. The sampling procedure at each location consisted of purging approximately 2 liters (L) of air, analyzing the oxygen, carbon dioxide and methane content of the purged air and then collecting the sub-slab vapor sample in evacuated 6 L stainless steel summa canisters. The work plan indicated that samples would be collected in 1 L

stainless steel summa canisters; however, the 6 L canisters were necessary to achieve the lower detection limits. During sampling events prior to January 2014, isopropyl alcohol (2-propanol) was used as a leak detection compound. During the January 2014 sampling event and this sampling event, helium was used as the leak detection gas in accordance with Missouri Risk-Based Corrective Action Process for Petroleum Storage Tanks Appendix C, Evaluation of the Vapor Intrusion Pathway dated October 17, 2013 and Guidance for Evaluating Soil Vapor Intrusion in the State of New York dated October 2006 guidance documents. See Figure 7 for helium tracer setup schematic. The following procedures were followed during the helium leak test portion of the sub-slab vapor sampling:

Ensure sample port, Summa canister, sample train and all tubing connections are underneath a shroud at the respective sample port. One section of tubing leads to the outside of the shroud. A three-way stopcock valve placed underneath the shroud is used to control flow to the tubing leading out of the shroud (flow is allowed between only two lines attached to stopcock valve at any one time). The stopcock valve and Summa canister valve are controlled from outside the shroud by reaching through sealed access points installed on the shroud.

Introduce helium into the shroud through tubing connected to the helium canister and regulator until it reaches a concentration that is greater than 10% (measure the concentration of helium under the shroud using a helium detector by inserting the helium detector probe through a previously installed access point on the shroud).

Test integrity of sample port by first purging the tubing connected to the sample port that leads out of the shroud then collecting a sample from the line and port using a syringe and analyzing it with the helium meter (flow is from sample port to tubing leading outside of shroud). In addition, the helium detector probe is inserted into the tubing that leads out of the shroud.

Test the integrity of the sampling train from the summa canister to the line leading out of the shroud by conducting a vacuum test (apply vacuum with hand pump and monitor for any decay in vacuum using vacuum gauge, flow is from Summa canister to tubing leading outside of shroud).

Verify helium level remains greater than 10% in shroud by placing helium detector probe into access point.

Collect sub-slab vapor sample through sample port while maintaining helium level in shroud (flow is from sample port to Summa canister).

After sampling recheck helium level in the chamber to verify concentration greater than 10% was maintained during collection of sub-slab vapor sample.

Because minor leakage around the sample port should not materially affect the usability of the sub-slab vapor results, the mere presence of helium in the sample should not be cause for concern. If high levels (>5%) of helium are detected, the fittings will be tightened and the sampling train resampled. If elevated levels of helium are still present, abandonment and reinstallation will be considered as was the case with the southern sampling port at 622 East


Seventh Street. The southern sampling port at 622 East Seventh Street was abandoned, cleared of debris and reinstalled at the same location. Vapor samples were submitted to Eurofins Air Toxics, Inc. for analysis of constituents detected during previous soil and groundwater investigations [1,1-dichloroethene (1,1-DCE), cis-1,2-dichloroethene (cis-DCE), tetrachloroethene (PCE), trichloroethene (TCE), vinyl chloride (VC) and benzene] and the leak detection compound (helium) using EPA method Modified TO-15 (SIM Method). RESULTS Hydrogeology The depth to groundwater measured in MW-2 though MW-12 (MW-1 was dry) ranged from approximately 7.86 feet below ground surface (bgs) at MW-9 to 15.15 feet bgs at MW-6. Figure 1 shows the shallow groundwater surface contours based on groundwater elevations measured on February 10, 2015. As shown on this figure, the shallow groundwater surface slopes primarily to the south with a southwesterly component on western portions of the site and a southeasterly component on eastern portions of the site, generally mimicking the surface and top of bedrock topography at the site. The groundwater flow direction, gradient and average elevations are consistent with those observed during previous monitoring events. The current groundwater elevations are the fourth highest out of the previous nine sampling events dating back to September 2009. Groundwater Sampling Results Laboratory results from the February 2015 sampling of all monitoring wells are summarized on Tables 1A and 1B. The laboratory reports are provided in Appendix B. The calculated residential Tier 2 Site-Specific Target Levels (SSTLs)2 for the indoor inhalation of vapor emissions from groundwater based upon site-specific groundwater levels and geotechnical soil data collected during previous investigations resulted in Tier 2 SSTLs for TCE and VC of 4.06 milligrams (mg)/L and 0.268 mg/L, respectively, as presented in the Letter Report for Phase III Supplemental Investigation dated June 12, 2012 and Response to MDNR Comment Letter Dated October 16, 2012 dated December 7, 2012. A Tier 2 SSTL for cis-DCE of 17.5 mg/L was calculated using the same methodology presented in the Response to MDNR Comment Letter Dated October 16, 2012 dated December 7, 2012.

2 Based on the MDNR letter dated June 20, 2013, it is ENVIRON’s understanding that new Tier 1 RBTLs will be available for implementation in the next few months. However, the time frame for updating the MRBCA software used in Tier 2 calculations is currently unknown. In the interim, the previously calculated Tier 2 SSTLs will be used for comparison. As of February 2015, the Tier 1 RBTLs have not been updated.


Onsite Wells Onsite wells consist of MW-1 through MW-5. No groundwater was present in MW-1. No VOCs were detected in MW-2 through MW-5 at concentrations exceeding the Tier 1 RBTLs for a non-residential land use. The TCE concentration in MW-5 (5.87 mg/L) and MW-3 (4.43 mg/L) exceeds the Tier 2 SSTL of 4.06 mg/L for unrestricted land use. Offsite Wells

Offsite wells consist of MW-6 through MW-12. TCE concentrations detected in groundwater samples do not exceed the Tier 2 SSTL (4.06 mg/L) for unrestricted land use at any well location, except for MW-8 (5.67 mg/L). VC concentrations detected in groundwater samples do not exceed the Tier 2 SSTL (0.268 mg/L) for an unrestricted land use scenario at any well location except MW-8 (0.535 mg/L). TCE was the only constituent detected in offsite wells MW-11 and MW-12 and TCE, cis-DCE and VC were the only constituents detected in offsite well MW-10 during this sampling event. Concentrations have been approximately one order of magnitude or more below the Tier 2 RBTLs for Soil Type 2 for an unrestricted land use scenario. Plume Stability Analysis

In order to analyze the stability of the groundwater plume at the site, several analytical tools or “lines of evidence” were used to evaluate overall plume stability including:

Time vs. Concentration Plots: Qualitative method to evaluate temporal trends in constituent concentration for individual wells and for representative concentration of overall plume (mean and geometric mean). The plots also include simple linear regression line to aid the analysis of temporal trends.

Isoconcentration Maps: Qualitative method to evaluate temporal trends by comparing representations of plume concentration and extent for certain periods over the duration of monitoring.

Statistical Methods: Mann-Kendall nonparametric test (Gilbert, 1987; USEPA, 2000) to calculate the temporal trend in individual well analyte concentrations over time.

In addition, ENVIRON analyzed time vs. concentration plots along with water level data to analyze potential variability in concentration data related to water level fluctuations or other seasonal changes in site conditions.


Groundwater monitoring events performed since May 2007 include:

Twelve monitoring events over a period of seven years and nine months for the onsite wells (MW-1 through MW-5);

Eleven monitoring events over a period of six years and seven months for the offsite wells immediately down-gradient of the site (MW-6 through MW-9); and

Nine monitoring events spread over a period of five years and four months for the offsite wells delineating the extent of impact (MW-10 through MW-12).

These groundwater monitoring events include sequential quarterly monitoring performed in 2012 into January 2013 and annual monitoring since January 2013.

Groundwater samples have only been obtained from MW-1 three times (May 2007, January 2010 and April 2010) during this period due to an insufficient volume of water during the other sampling events; therefore, MW-1 is not included in the plume stability analysis because at least four results are generally required for trend analysis to be considered statistically valid. The presence or absence of water in MW-1 does not affect plume stability. Further investigation of the source area and MW-1 was performed in April 2012 with the results presented in the Letter Report for Phase III Supplemental Investigation dated June 12, 2012.

Time vs Concentration Plots

Figures 3A, 3B and 3C show the change in concentrations of TCE, cis-DCE and VC (respectively) in groundwater samples from site monitoring wells over time from September 2009 to February 2015. Based on a review of the figures and the underlying data, key observations are as follows:

A decreasing trend in TCE concentrations is shown at the majority of the wells (six of 11 wells including MW-3, MW-4, MW-6, MW-7, MW-8 and MW-9);

At the four wells with no trend or an increasing TCE trend (MW-23, MW-10, MW-11 and MW-12), TCE concentrations are one to two orders of magnitude below the Tier 2 SSTL;

At stable trend in TCE concentrations at MW-5;

The decreasing trend for TCE is greatest at MW-3 and MW-7 (i.e., regression lines with the steepest slope);

The concentrations of cis-DCE in all wells are one to two orders of magnitude below the Tier 2 SSTL of 17.5 mg/L;

3 Although no concentration trend is statistically observed at MW-2, since July 2008 the TCE concentrations in MW-2 have ranged from less than 0.001 mg/L (i.e. non-detect) to 0.0194 mg/L. Therefore, TCE concentration trend analysis in MW-2 indicates TCE concentrations are typically near or below the DTL. No further discussion of concentration trend analysis is presented regarding MW-2 since the constituent concentrations are typically near or below the DTL.


At the three wells with stable or increasing trends of VC concentrations (MW-4, MW-5 and MW-10), concentrations are one (MW-4 and MW-5) to two (MW-10) orders of magnitude below the Tier 2 SSTL; and

VC concentrations are greater than the Tier 2 SSTL at MW-8 however, concentrations at this well exhibit a decreasing temporal trend.

Figures 4A, 4B and 4C show the change in the average4 plume concentration of TCE, cis-DCE and VC (respectively) in groundwater samples for each monitoring event over time from September 2009 to February 2015. Based on a review of the figures and the underlying data, key observations are as follows:

A decreasing trend in average concentrations is shown for TCE, cis-DCE and VC;

All of the average plume concentrations are below the respective Tier 2 SSTL; and

The average concentrations of cis-DCE are an order of magnitude less than the Tier 2 SSTL.

Based on the above observations for the time vs. concentration plots it is evident that the concentrations of the primary COCs (TCE and its degradation products) in groundwater at the site are stable to decreasing especially in the case of the parent constituent TCE.

Isoconcentration Maps

Figure 2 shows isoconcentration lines for the unrestricted Tier 2 SSTL for TCE for the September 2009 monitoring event (first monitoring event that included all 12 site monitoring wells) and the latest monitoring event in February 2015. The figure shows that the extent of the plume exceeding the Tier 2 SSTL has shifted slightly to the northeast and decreased from the September 2009 monitoring event to the February 2015 monitoring event, thus indicating that the groundwater plume delineated to the Tier 2 SSTL is shrinking.

Statistical Analysis

The Mann-Kendall nonparametric test (Gilbert, 1987; USEPA, 2000) was used to calculate the temporal trend in analyte concentrations over time. The applicable outcomes of the temporal trend analysis are as follows:

Increasing: Statistically significant increasing trend for concentrations (>90% confidence);

Stable: No statistically significant trend for concentrations along with low variability for results (Coefficient of Variance <1);

No Trend: No statistically significant trend for concentrations along with high variability for results (Coefficient of Variance >1);

4 The average plume concentration is the mean concentrations for all wells sampled during an individual monitoring event. The reporting limit value is used for wells were a constituent is not detected in the sample.


Decreasing: Statistically significant decreasing trend for concentrations (>90% confidence);

ND: Constituent has not been detected at the well during the time period analyzed;

<PQL: All sample results have a qualifier of “J”, or the results are a mixture on non-detects and results having a “J” qualifier; and

<4 Results: Fewer than four measurements for COC; no trend evaluated. The following table contains the outcomes of the temporal trend analysis for primary constituents of concern (COCs) at onsite and offsite wells along with the number of samples included in the analysis:

Natural attenuation of chlorinated solvents in soil and groundwater may occur via anaerobic reductive dechlorination. The sequence of anaerobic reductive dechlorination generally consists of: TCE degradation to cis- and trans-1, 2-DCE; cis- and trans-1, 2-DCE degradation to VC; and VC degradation to ethenes (aerobic). The summary discussion of plume stability below is provided in the sequence of anaerobic reductive dechlorination.


Trichloroethene

TCE concentrations exhibit:

Decreasing concentration trend at MW-3, MW-4, MW-6, MW-7, MW-8 and MW-9; Stable concentration trend at MW-5 and MW-10; Increasing concentration at MW-11 and MW-12; and No concentration trend at MW-2.

TCE concentrations at MW-11 and MW-12 are slightly lower than 2014 concentrations and still more than one order of magnitude below the Tier 2 SSTL (0.194 mg/L and 0.0228 mg/L, respectively vs. 4.06 mg/L) and this increase in TCE concentration trend is not unexpected at wells located near the down-gradient edge of the plume. TCE concentration linear trends are forecast for one year until January 2016 on Figures 3A and 4A to emphasize the future concentrations trends in relation to the respective Tier 2 SSTL. Although, MW-11 and MW-12 may exhibit marginally increasing TCE concentration trends, the slope of the TCE linear trend line for MW-11 and MW-12 on Figure 3A indicate the TCE concentrations in these wells will not approach the Tier 2 SSTL since the concentration trends in up-gradient wells are either decreasing or stable and due to advection and dispersion for the groundwater plume. cis-1,2-Dichloroethene

cis-DCE concentrations exhibit:

Decreasing concentration trend at MW-2, MW-3, MW-4, MW-6 and MW-10; Stable concentration trend at MW-5, MW-8 and MW-9; No concentration trend at MW-7; and No detections at MW-11 and MW-12.

The average concentrations of cis-DCE are an order of magnitude less than the Tier 2 SSTL. Vinyl Chloride

VC concentrations exhibit:

Decreasing trend at MW-2 and MW-8; Stable concentration trend at MW-5; No concentration trend at MW-4; Less than PQL at MW-10; and No detections at MW-3, MW-6, MW-7, MW-9, MW-11 and MW-12.

VC concentration linear trends are forecasted up to January 2016 on Figures 3C and 4C to emphasize the future concentrations trends in relation to the respective Tier 2 SSTL. Excluding MW-8, the slope of the VC concentration trend lines are relatively flat and therefore, concentrations at these wells are anticipated to remain below the Tier 2 SSTL.


The VC concentrations are expected to vary in the future as TCE and cis-DCE undergo anaerobic reductive dechlorination. The anticipated future varying concentrations of cis-DCE and VC are not indicative of plume instability, but rather strong evidence of anaerobic reductive dechlorination reducing the mass of chlorinated solvents present in the groundwater plume. In summary, the statistical analysis for temporal trends in TCE, cis-DCE and VC concentrations for the groundwater plume indicate that the plume concentrations are predominantly decreasing to stable. An increasing trend of the parent constituent (TCE) is observed at only two wells located near the down-gradient edge of the plume at concentrations more than one order of magnitude below the Tier 2 SSTL (MW-11 and MW-12). Hydrogeology Trend Analysis The hydraulic trend analysis was accomplished through the qualitative review of shallow groundwater elevation contour maps generated for nine groundwater monitoring events since September 2009. The average water level elevation for the monitoring events has varied within a range of approximately 4 feet. Figure 5 shows average groundwater elevations and average site concentrations over time. The observed groundwater gradient and direction of flow have remained consistent since September 2009. Sub-Slab Vapor Sample Results Sub-slab vapor sample monitoring results are summarized on Tables 3 through 5. The sub-slab vapor data is compared to Tier 1 RBTLs for sub-slab vapors adjusted by a factor of 10 (modified Tier 1 RBTL) in accordance with the MDNR letter dated June 20, 2013. The laboratory reports are provided in Appendix C. The modified Tier I RBTLs for sub-slab vapors for TCE, cis-1,2-DCE and VC are 0.128 mg/m3, 0.043 mg/m3 and 0.0291 mg/m3. TCE, PCE and cis-DCE were the only target constituents detected above their respective reporting limits in the sub-slab vapor samples collected during this sampling event. However, PCE was not detected in groundwater samples. TCE was detected in samples from the west port at 604 East Seventh Street and the east port at 612 East Seventh Street at concentrations of 0.00068 mg/cubic meter (m3) and 0.12 mg/m3, respectively. Cis-DCE was detected in the sample from the east port at 612 East Seventh Street at a concentration of 0.00039 mg/m3. TCE, PCE and cis-DCE concentrations detected in sub-slab vapor samples do not exceed modified Tier 1 RBTLs for sub-slab vapors at any location. Helium (leak detection gas) was not detected in any sub-slab vapor samples collected.


Sub-slab vapor sampling ports (two at each of the four properties south of Seventh Street) have been subject to sampling eight times over the previous six years and four months since installation (October 2008, April 2010, April 2012, July 2012, October 2012, January 2013, January 2014 and February 2015)5. The following is a summary of current and previous sub-slab vapor sampling results:

The only target constituents detected during sub-slab vapor monitoring events at concentrations greater than the modified Tier 1 RBTLs were PCE during the October 2008 sampling event at the 612 East Seventh Street west port and TCE marginally exceeding the modified Tier 1 RBTL during the January 2013 sampling event at the 612 East Seventh Street east port (0.13 mg/m3 versus the 0.128 mg/m3).

CONCLUSIONS ENVIRON performed groundwater and sub-slab monitoring at the former Sporlan Valve Plant No. 1 in February 2015. Based on the field observations and analytical results from this groundwater and sub-slab vapor monitoring, previous onsite and offsite investigations and previous soil, groundwater and sub-slab vapor monitoring events, ENVIRON concludes the following:

Soil

No onsite soil impact exceeded Tier 1 RBTLs for indoor inhalation of vapor emissions from surface or subsurface soil samples for a Soil Type 2 (Silty) for non-residential land use based upon the data from the supplemental investigation performed in April 2012 with the results presented in the Letter Report for Phase III Supplemental Investigation dated June 12, 2012, and the previous investigations performed at the site.

Offsite soil impacts were limited to the detection of TCE in two subsurface saturated soil samples. TCE was detected in MW7-GP16-24.75’ and MW9-GP18-27.25’ at 0.314 mg/kilograms (kg) and 0.029 mg/kg, respectively. These concentrations are at least an order of magnitude below the Tier 1 RBTLs for indoor inhalation of vapor emissions from subsurface soil samples for a Soil Type 2 (Silty) for residential land use (the Tier 1 RBTL for TCE is 2.92 mg/kg).

Groundwater

The shallow water-bearing zone at the site is not a potentially exploitable aquifer based on the criteria outlined in the MRBCA Document (Offsite Investigation Letter Report, Former Sporlan Valve Company Plant No. 1. 611 East Seventh Street Washington,

5 The eight monitoring events were performed for each sampling port except for the western sample port at 604 East Seventh Street (sampled seven times), the eastern sample port at 612 East Seventh Street (sampled seven times), the northern sample port at 616 East Seventh Street (sampled two times and not sampled during this event) and the southern sample port at 616 East Seventh Street (sampled six times and not sampled during this event) as described in previous monitoring reports.


Missouri prepared by ENVIRON dated February 20, 2009). Given this determination and since there are currently no groundwater extraction wells at the site and that the City of Washington Ordinances regulating groundwater use prohibit such wells6, the “domestic use of groundwater” exposure pathway associated with this water-bearing zone is incomplete and therefore has not been considered while assessing cleanup criteria for the site (as discussed during our June 24, 2009, meeting).

Consistent with prior investigations, no constituent concentrations in groundwater from onsite wells (MW-1 through MW-5) exceed the “indoor inhalation of vapor emission” RBTLs for Soil Types 2 for non-residential land use.

Consistent with prior investigations, no concentrations in groundwater from onsite wells (MW-1 through MW-5) exceed the Tier 2 SSTL for unrestricted land use except for the TCE concentrations detected in groundwater in MW-3 and MW-5 (4.43 mg/L and 5.87 mg/L, respectively vs. 4.06 mg/L).

Consistent with prior investigations, no constituent concentrations in groundwater from offsite wells (MW-6 through MW-12) exceed the Tier 2 SSTL for unrestricted land use except for TCE and VC concentrations detected in groundwater in MW-8 (5.67 mg/L vs. 4.06 mg/L and 0.535 mg/L vs. 0.269 mg/L, respectively).

TCE, cis-DCE and VC were detected in offsite wells MW-10, MW-11 and MW-12 during this sampling event. Concentrations have been approximately one order of magnitude or more below RBTLs for “indoor inhalation of vapor emissions from groundwater” for an unrestricted land use scenario. These three wells therefore define the extent of offsite groundwater impact down-gradient of the facility and no further investigation is necessary to delineate the extent of groundwater impact.

A comprehensive analysis of groundwater plume stability using multiple methods indicates that groundwater conditions at the site are very consistent relative to both physical and chemical parameters. Overall trends in concentrations of the parent COC TCE are decreasing and concentrations of daughter COCs cis-DCE and VC are decreasing to stable (Figures 4A-4C). The extent of the groundwater plume delineated at concentrations equal to or greater than the Tier 2 SSTLs for unrestricted land use scenario for “indoor inhalation of vapor emissions from groundwater” is shrinking (Figure 6).

Any open well, cistern or excavation in which there may be refuse or stagnant water or which may be a hazard to persons or animals or that may be an attraction and danger to children is hereby declared to be a nuisance.


Sub-Slab Vapor

No constituent concentrations in sub-slab vapor samples exceeded the modified Tier 1 RBTLs for sub-slab vapors at any location during the February 2015 monitoring event.

Sub-slab vapors exhibiting constituent concentrations exceeding the modified Tier 1 RBTLs have only been measured at 612 East Seventh Street. PCE was detected at concentrations exceeding the modified Tier 1 RBTLs in October 2008; although, PCE was not detected in groundwater in MW-7 located at 612 East Seventh Street. PCE was detected in sub-slab vapor at concentrations an order of magnitude or greater below the modified Tier 1 RBTL at 612 East Seventh Street during the January 2014 and February 2015 monitoring events. TCE was detected in the eastern port at 612 East Seventh Street at 0.13 mg/m3 which marginally exceeds the 0.128 mg/m3 modified Tier 1 RBTLs in January 2013 (TCE was not detected in the corresponding western port during the January 2013 monitoring event).

Definitions






Abbr DefinitionCCV Continuing calibration verification is a check of a standard to determine the state of calibration of an instrument between recalibration.

DF Dilution factor is the dilution performed during analysis only and does not take into account any dilutions made during sample preparation. The reported result is final and includes all dilutions factors.

DNI Did not ignite

DUP Laboratory duplicate is an aliquot of a sample taken from the same container under laboratory conditions for independent processing and analysis independently of the original aliquot.

ICV Initial calibration verification is a check of a standard to determine the state of calibration of an instrument before sample analysis is initiated.

IDPH IL Dept. of Public Health

LCS Laboratory control sample, spiked with verified known amounts of analytes, is analyzed exactly like a sample to establish intra-laboratory or analyst specific precision and bias or to assess the performance of all or a portion of the measurement system. The acceptable recovery range is in the QC Package (provided upon request).

LCSD Laboratory control sample duplicate is a replicate laboratory control sample that is prepared and analyzed in order to determine the precision of the approved test method. The acceptable recovery range is listed in the QC Package (provided upon request).

MB Method blank is a sample of a matrix similar to the batch of associated sample (when available) that is free from the analytes of interest and is processed simultaneously with and under the same conditions as samples through all steps of the analytical procedures, and in which no target analytes or interferences should present at concentrations that impact the analytical results for sample analyses.

MDL Method detection limit means the minimum concentration of a substance that can be measured and reported with 99% confidence that the analyte concentration is greater than zero.

MS Matrix spike is an aliquot of matrix fortified (spiked) with known quantities of specific analytes that is subjected to the entire analytical procedures in order to determine the effect of the matrix on an approved test method’s recovery system. The acceptable recovery range is listed in the QC Package (provided upon request).

MSD Matrix spike duplicate means a replicate matrix spike that is prepared and analyzed in order to determine the precision of the approved test method. The acceptable recovery range is listed in the QC Package (provided upon request).

MW Molecular weight

ND Not Detected at the Reporting Limit

NELAP NELAP Accredited

PQL Practical quantitation limit means the lowest level that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operation conditions. The acceptable recovery range is listed in the QC Package (provided upon request).

RL The reporting limit the lowest level that the data is displayed in the final report. The reporting limit may vary according to customer request or sample dilution. The reporting limit may not be less than the MDL.

RPD Relative percent difference is a calculated difference between two recoveries (ie. MS/MSD). The acceptable recovery limit is listed in the QC Package (provided upon request).

SPK The spike is a known mass of target analyte added to a blank sample or sub-sample; used to determine recovery deficiency or for other quality control purposes.

Surr Surrogates are compounds which are similar to the analytes of interest in chemical composition and behavior in the analytical process, but which are not normally found in environmental samples.

TNTC Too numerous to count ( > 200 CFU )

Qualifiers# - Unknown hydrocarbon B - Analyte detected in associated Method Blank

E - Value above quantitation range H - Holding times exceeded

J - Analyte detected below quantitation limits M - Manual Integration used to determine area response

ND - Not Detected at the Reporting Limit R - RPD outside accepted recovery limits

Definitions






Abbr DefinitionCCV Continuing calibration verification is a check of a standard to determine the state of calibration of an instrument between recalibration.

DF Dilution factor is the dilution performed during analysis only and does not take into account any dilutions made during sample preparation. The reported result is final and includes all dilutions factors.

DNI Did not ignite

DUP Laboratory duplicate is an aliquot of a sample taken from the same container under laboratory conditions for independent processing and analysis independently of the original aliquot.

ICV Initial calibration verification is a check of a standard to determine the state of calibration of an instrument before sample analysis is initiated.

IDPH IL Dept. of Public Health

LCS Laboratory control sample, spiked with verified known amounts of analytes, is analyzed exactly like a sample to establish intra-laboratory or analyst specific precision and bias or to assess the performance of all or a portion of the measurement system. The acceptable recovery range is in the QC Package (provided upon request).

LCSD Laboratory control sample duplicate is a replicate laboratory control sample that is prepared and analyzed in order to determine the precision of the approved test method. The acceptable recovery range is listed in the QC Package (provided upon request).

MB Method blank is a sample of a matrix similar to the batch of associated sample (when available) that is free from the analytes of interest and is processed simultaneously with and under the same conditions as samples through all steps of the analytical procedures, and in which no target analytes or interferences should present at concentrations that impact the analytical results for sample analyses.

MDL Method detection limit means the minimum concentration of a substance that can be measured and reported with 99% confidence that the analyte concentration is greater than zero.

MS Matrix spike is an aliquot of matrix fortified (spiked) with known quantities of specific analytes that is subjected to the entire analytical procedures in order to determine the effect of the matrix on an approved test method’s recovery system. The acceptable recovery range is listed in the QC Package (provided upon request).

MSD Matrix spike duplicate means a replicate matrix spike that is prepared and analyzed in order to determine the precision of the approved test method. The acceptable recovery range is listed in the QC Package (provided upon request).

MW Molecular weight

ND Not Detected at the Reporting Limit

NELAP NELAP Accredited

PQL Practical quantitation limit means the lowest level that can be reliably achieved within specified limits of precision and accuracy during routine laboratory operation conditions. The acceptable recovery range is listed in the QC Package (provided upon request).

RL The reporting limit the lowest level that the data is displayed in the final report. The reporting limit may vary according to customer request or sample dilution. The reporting limit may not be less than the MDL.

RPD Relative percent difference is a calculated difference between two recoveries (ie. MS/MSD). The acceptable recovery limit is listed in the QC Package (provided upon request).

SPK The spike is a known mass of target analyte added to a blank sample or sub-sample; used to determine recovery deficiency or for other quality control purposes.

Surr Surrogates are compounds which are similar to the analytes of interest in chemical composition and behavior in the analytical process, but which are not normally found in environmental samples.

TNTC Too numerous to count ( > 200 CFU )

Qualifiers# - Unknown hydrocarbon B - Analyte detected in associated Method Blank

E - Value above quantitation range H - Holding times exceeded

J - Analyte detected below quantitation limits M - Manual Integration used to determine area response

ND - Not Detected at the Reporting Limit R - RPD outside accepted recovery limits

S - Spike Recovery outside recovery limits X - Value exceeds Maximum Contaminant Level

LABORATORY NARRATIVEModified ASTM D-1946Environ InternationalWorkorder# 1502252B

Six 6 Liter Summa Canister (SIM Certified) samples were received on February 16, 2015. The laboratory performed analysis via Modified ASTM Method D-1946 for Helium in air using GC/TCD.The method involves direct injection of 1.0 mL of sample.


Requirement ATL ModificationsASTM D-1946Calibration A single point

calibration is performed using a reference standard closely matching the composition of the unknown.

A minimum of 5-point calibration curve is performed. Quantitation is based on average Response Factor.

Reference Standard The composition of any reference standard must be known to within 0.01 mol % for any component.

The standards used by ATL are blended to a >/= 95% accuracy.

Sample Injection Volume Components whose concentrations are in excess of 5 % should not be analyzed by using sample volumes greater than 0.5 mL.

The sample container is connected directly to a fixed volume sample loop of 1.0 mL on the GC. Linear range is defined by the calibration curve. Bags are loaded by vacuum.

Normalization Normalize the mole percent values by multiplying each value by 100 and dividing by the sum of the original values. The sum of the original values should not differ from 100% by more than 1.0%.

Results are not normalized. The sum of the reported values can differ from 100% by as much as 15%, either due to analytical variability or an unusual sample matrix.

Precision Precision requirements established at each concentration level.

Duplicates should agree within 25% RPD for detections > 5 X's the RL.

Receiving Notes


There were no analytical discrepancies.

LABORATORY NARRATIVEModified ASTM D-1946Environ InternationalWorkorder# 1502384B

One 6 Liter Summa Canister (SIM Certified) sample was received on February 24, 2015. The laboratory performed analysis via Modified ASTM Method D-1946 for Helium in air using GC/TCD.The method involves direct injection of 1.0 mL of sample.


Requirement ATL ModificationsASTM D-1946Calibration A single point

calibration is performed using a reference standard closely matching the composition of the unknown.

A minimum of 5-point calibration curve is performed. Quantitation is based on average Response Factor.

Reference Standard The composition of any reference standard must be known to within 0.01 mol % for any component.

The standards used by ATL are blended to a >/= 95% accuracy.

Sample Injection Volume Components whose concentrations are in excess of 5 % should not be analyzed by using sample volumes greater than 0.5 mL.

The sample container is connected directly to a fixed volume sample loop of 1.0 mL on the GC. Linear range is defined by the calibration curve. Bags are loaded by vacuum.

Normalization Normalize the mole percent values by multiplying each value by 100 and dividing by the sum of the original values. The sum of the original values should not differ from 100% by more than 1.0%.

Results are not normalized. The sum of the reported values can differ from 100% by as much as 15%, either due to analytical variability or an unusual sample matrix.

Precision Precision requirements established at each concentration level.

Duplicates should agree within 25% RPD for detections > 5 X's the RL.
