Groundwater Permit-by-Rule (DGW-PBR) PROGRESS REPORT

Revision: 0 Date: February 2, 2017

1.0 INTRODUCTION

On behalf of Hoffmann-La Roche Inc. (Roche), TRC Environmental Corporation (TRC) has prepared this Interim Remedial Measure (IRM) Progress Report for shallow groundwater in Investigative Area (IA)-1 near former Building 55, hereinafter referred to as the IA-1 Building 55 Progress Report, for the Roche Facility (Site) located at 340 Kingsland Street, Nutley, New Jersey. The Site is situated on approximately 120 acres of land within the City of Clifton, Passaic County and the Township of Nutley, Essex County. The 2015 IA-1 Building 55 IRM Progress Report provides a summary of the treatment program, including methods, amendment quantities, and supporting data. The groundwater monitoring results through January 2016 (4-months post-treatment) are transmitted herein and provide a preliminary assessment of remedial progress. Since remediation is in progress, it is premature to perform detailed evaluations of the results and develop conclusions. Detailed evaluations and conclusions will be provided in a subsequent submittal. The IA-1 Building 55 IRM, which consisted of an in situ chemical oxidation (ISCO) treatment program, was implemented in accordance with the Permit-By-Rule (PBR) Notification Approval letter provided by the New Jersey Department of Environmental Protection (NJDEP), dated March 3, 2015 (Appendix A). TRC completed the soil amendment portion of the 2015 ISCO Program in August 2015 and reports the progress herein. This 2015 IA-1 Building 55 Progress Report submission satisfies the reporting requirements set forth in the NJDEP’s PBR Notification Approval letter. This report describes groundwater remediation activities during the period from April 1, 2015 through January 31, 2016.

1.1 Background Information

The main campus of the Roche Nutley facility was developed for industrial purposes in 1928 for the manufacturing of vitamins, fine chemicals, pharmaceuticals and research and development. Prior to Roche’s ownership, the main campus area primarily was used for agricultural purposes. Some portions of the current property were previously owned and operated by non-Roche entities for various commercial and manufacturing purposes; these parcels were purchased by Roche over a period of several decades subsequent to 1928. The Site has been divided into discrete investigative areas for purposes of completing a Remedial Investigation of site soil and groundwater. Investigative Area 1 (IA-1) is located in the northwestern portion of the Roche Nutley Facility (Figure 1). IA-1 consists of an area of production and waste treatment/recycling facilities (former Building 30) initially developed in the 1940s and 1950s, as well as tank storage (both above and below ground) that included a 640,000 gallon No. 6 fuel oil above

of 10

ground storage tank (AST) and an oxygen storage area. The majority of IA-1 was historically used by Roche for facility maintenance, fuel oil storage, utilities, and manufacturing. This IA includes areas of concern (AOCs) consisting of ASTs, underground storage tanks (USTs), raw and hazardous material storage areas, electrical transformers and production building footprints. Remedial investigation (RI) activities specific to IA-1 Building 55 soil were conducted from December 2012 to August 2013 and documented in a report (Remedial Investigation Report – Investigation Area Nos. 1[IA-1] and 5 [IA-5], TRC November 18, 2013). Additional investigative information for groundwater in IA-1 was obtained as part of a site-wide groundwater RI (Site-wide Ground Water Remedial Investigation Report, Revision 3, TRC April 2, 2014). Soil remedial activities were conducted in IA-1/IA-5 between April 2015 and August 2015, and are documented in a Remedial Action Report (Soil Remedial Action Report – Investigative Areas (IAs) 1 and 5, TRC January 19, 2016). Extensive drilling and sampling was performed through the RI and subsequent investigative efforts to characterize groundwater elevations and delineate groundwater contamination horizontally and vertically. To aid in the visualization and interpretation of these data, seven vertical investigation zones were defined based on elevation relative to mean sea level. These are:

• Shallow Zone S1 (greater than 80 feet above msl); • Shallow Zone S2 (between 80 to 50 feet above msl); • Shallow Zone S3 (between 50 to 0 feet above msl); • Deep Zone D1 (between elevation 0 to 100 feet below msl); • Deep Zone D2 (between 100 to 250 feet below msl); • Deep Zone D3 (between 250 to 400 feet below msl); and, • Deep Zone D4 (greater than 400 feet below msl).

These vertical investigation zones are elevation-based for project organizational/management purposes only. All groundwater elevation and quality data have been compiled and evaluated for delineation and remediation using this groundwater elevation investigation zone system, as discussed in the Groundwater Remedial Investigation Report (GWRIR) and Groundwater Progress Reports (GWPRs).

Roche is currently preparing a Conceptual Site Model (CSM) for the Site that builds on historic work as well as the broad knowledge base gained during the site investigations. Based on detailed analysis of stratigraphic and geophysical data, the vertical zonation of the groundwater flow system and movement of impacted groundwater is likely to be redefined, and the data will be reorganized accordingly. TRC is the environmental consultant for Roche and has been assisting Roche with multiple environmental investigations being conducted on the Nutley, NJ property. Roche has directed TRC to design and implement an ISCO soil treatment program to accelerate the remediation of shallow, overburden groundwater associated with the IA-1, in the former Building 55 area.

1.2 Site Setting

IA-1 and IA-5 occupy approximately 7.3 acres and are mostly paved. The current Site topography in IA-1 is relatively flat; however, there is a portion of a soil berm in the northwest corner of IA-1, and a steep hill in the northernmost portion of IA-1 behind former Building 50. The remainder of the northern section of IA-1 has a gentle slope toward the west-southwest, and the southern section has a gentle slope toward the south-southeast. Based on numerous subsurface soil borings completed throughout IA-1, the soils beneath IA-1 are primarily comprised of red-brown silt and sand, typical for the Roche site. The bedrock at the facility is part of the Passaic Formation and contains dark reddish-brown siltstone intergraded with fine to medium-grained silty sandstone and shale. A weathered bedrock zone is present throughout much of the facility in the upper portion of the bedrock. The depth to bedrock ranges from approximately 3 to 12 feet below ground surface. Based on data collected by Roche in 2014, the general groundwater flow direction in the vicinity of IA-1 is to the south-southeast. Synoptic groundwater elevation data indicate that groundwater flow direction is consistent with that observed in previous years. Depth-to-water is approximately 5 feet below ground surface.

1.3 Summary of Primary Contaminants

The primary contaminants of concern (COCs) in groundwater associated with the IA-1 former Building 55 Area are toluene, chloroform, and methylene chloride above the Ground Water Quality Standards (GWQS) along the east and west sides of former Building 55 (Figure 2). Additionally, although not associated with the former Building 55 Area, benzene concentrations in exceedance of the GWQS have been reported in several of the IA-1 monitoring wells. During the 1st quarter 2015 sampling event (March 2015), groundwater samples from shallow overburden monitoring wells MW-254A and MW-255A (located along B55 West and B55 East, respectively) exhibited the following:

• MW-254A - toluene at 22,400 parts per billion (ppb)

• MW-255A

- chloroform at 4,710 ppb; - methylene chloride at 52.4 ppb; and - benzene at 71 ppb.

1.4 Previous Remediation Efforts

There have been no other remediation projects for shallow groundwater in this area.

1.5 Objectives

The objectives of the 2015 ISCO Treatment Program in the Building 55 area of IA-1 are:

of 10

1) To reduce the mass of volatile organic compound (VOC) constituents within the target areas of the overburden groundwater.

2) To reduce aqueous VOC concentrations within the target areas of the overburden groundwater.

1.6 Document Overview

This 2015 IA-1 Building 55 Progress Report provides introductory and background information, a summary of the ISCO treatment program (amendment quantities and application methods), and a report of the groundwater sampling results through January 2016 (4 months post-treatment). The final section provides an updated implementation schedule.

of 10

2.0 ISCO Treatment Program

In order to reduce the mass of the COCs in the areas of concern, catalyzed persulfate (sodium persulfate and calcium peroxide) was added to backfill up to the water table in the excavation locations, a depth of approximately 5 feet below ground surface. The ISCO treatment program included the following components:

• Excavation of Building 55 east and west down to groundwater level • Application of Oxygen BioChem™ (OBC™) • Treatment performance monitoring • Progress reporting

2.1 ISCO Treatment Summary

The field implementation was conducted by Redox Tech, Inc. with TRC-field supervision in August 2015. Following excavation to the water table, a strong chemical oxidizer, OBC™ was blended into the saturated soil in the top 1 to 2 feet of the water table using a backhoe. The soil amendment locations are detailed in Figure 3. OBC™ is an in situ chemical oxidation (ISCO) mixture supplied as a granular solid from Redox Tech, LLC formulated to remediate contaminated soil and groundwater via strong chemical oxidation. OBC™ treats soils and groundwater containing chlorinated VOC (CVOC) compounds, polycyclic aromatic hydrocarbons (PAHs), and benzene, toluene, ethylbenzene and xylene (BTEX). It consists of a mixture of sodium persulfate (70% to 90% by weight) and calcium peroxide (10% to 20%) that can be employed for ISCO applications using Klozur™ activation chemistry. The persulfate is activated by calcium peroxide (through alkalinity and peroxide) to generate sulfate radicals (SO42-), one of the strongest oxidizers available, which react rapidly with oxidizable constituents. In addition, OBC™ also provides electron acceptors (oxygen and sulfate) for longer-term biological degradation. The predominant short-term reaction is chemical oxidation (generally 1-2 months), while the longer-term remediation process is anaerobic biological degradation via sulfate reduction (generally 1-2 years). OBC™ has advantages over more traditional oxygen compounds used for bioremediation in that it works on a broader range of contaminants, including the toluene, chloroform, and methylene chloride found at Building 55. Because MW-254A had a higher total VOC concentration, the excavation on the northwest side of former Building 55 (B55 West) received a dose of 5 pounds (lbs) of persulfate per square foot of excavation, while the excavation on the southeast side of former Building 55 (B55 East) received 2 lbs of persulfate per square foot of excavation. A total of approximately 28,600 lbs of OBC™ were mixed into the excavation backfill. A material safety data sheet (MSDS) for the OBC™ is included in Appendix B. Details of the excavation are contained in the Soil Remedial Action Report, IA-1 and 5, dated January 19, 2016.

2.2 Groundwater Monitoring

Groundwater samples were collected in general accordance with the PBR using NJDEP-approved low-flow sampling methods. The monitoring performed and any deviations from the PBR monitoring program are summarized below. The groundwater Licensed Site Remediation Professional (LSRP) retained for the Site was notified of the PBR plan deviations, their technical basis, and potential impacts resulting from these modifications. It was concluded that these changes did not adversely affect the program objectives and/or data quality. To satisfy the requirements of the PBR, groundwater samples were collected from the following monitoring wells (Figure 2):

• Upgradient: MW-1 • Treatment Area: MW-255B • Downgradient: MW-256B, MW-391A, and MW-392A • Side-gradient: MW-390A

MW-1A was designated as the upgradient monitoring point in the permit; however, this well was damaged and decommissioned in April 2015. MW-1 was sampled in its place. In addition, downgradient monitoring well MW-256B was damaged in September 2015, and subsequently unavailable for monitoring for several sampling rounds. The monitoring wells were sampled in April 2015 prior to IA-1 soil remedial activities, approximately 4 months prior to the application of the soil amendment. This sampling event was used to define baseline conditions for each of the monitoring points. The wells were then sampled approximately 1 month after completion of the soil treatment, and again approximately three months thereafter, in accordance with the permit. The groundwater monitoring and sampling events reported in this progress report include:

• Pre-Excavation:

- April 2015: Baseline (pre-treatment) sampling event.

• Post-Treatment:

- September 2015: 1 month post-treatment groundwater sampling event.

- January 2016: 4 months post-treatment groundwater sampling event.

All but one of the samples collected were analyzed for VOCs and field geochemical parameters, in accordance with the permit. The sample collected from MW-1 in January 2016 was collected as a part of the regular site-wide monitoring using a passive diffusion bag sampler (PDB), and was analyzed for VOCs only, field geochemical data are not available for this sample. A summary of the analytical results to date is included in the sections below.

2.3 ISCO Study Results

Since remediation is ongoing, it is premature to perform detailed evaluations of the results and develop conclusions. Detailed evaluations and conclusions will be provided in a subsequent submittal. The following sections summarize the 2015 ISCO treatment program analytical results through January 2016 (4-months post-treatment), as well as the ISCO treatment preliminary conclusions as of January 2016. 2.3.1 Groundwater Quality Parameters The measurements of groundwater geochemical parameters collected for the January 2016 sampling event are summarized in Table 1. Field geochemical results for the April and September 2015 monitoring events were collected for other ongoing monitoring programs and will be submitted under separate cover. Laboratory reports and electronic data deliverables (EDDs) are included in Attachment 1. Generally, groundwater within and adjacent to the targeted area was evaluated for several geochemical characteristics:

• pH

- Important for biological activity

- Local groundwater showed a near-neutral pH which is favorable to the intended remediation.

• Dissolved oxygen (DO)

- Indicator of biological activity

- DO values ranged from below detection to 5.56 milligrams per liter (mg/L), with readings above 1 mg/L in the treatment area well (MW-255B; 1.59 mg/L) and side-gradient well (MW-390A; 5.56 mg/L). Areas where DO is greater than 1 mg/L are favorable for the biodegradation of toluene.

• Oxidation-reduction potential (ORP)

- Indicator of tendency of a chemical species to exchange electrons and thereby be oxidized or reduced

- Negative ORP in the treatment area and downgradient monitoring wells (ranging from approximately -100 to -300 mV). Negative ORP indicates that the treatment chemical (OBC) is not active in these areas.

2.3.2 VOC Results Table 2 summarizes the VOC data collected during the IRM monitoring period at the IA-1 former Building 55 area. Table 2 also includes results from the regular quarterly groundwater sampling events for wells MW-254A and MW-255A in March 2015 for reference. These wells were abandoned during excavation; however the data from these wells are representative of baseline conditions. Figure 2 shows the distribution of the COCs in groundwater prior to excavation and soil treatment, Figure 3 shows the excavation areas, and Figure 4 shows the distribution of the COCs in groundwater in January 2016 (4 months post-treatment). No COCs were detected in samples from upgradient well MW-1, or in side-gradient well MW-390A in any of the monitoring events. Methylene chloride was not detected at any wells during any of the monitoring events. Prior to excavation and soil treatment, toluene was detected at low concentrations at only one of the monitoring wells located downgradient of the treatment area (MW-391A). At MW-391A, the baseline toluene concentration reported in April 2015 was 0.18 µg/L; however toluene was not detected at this well (or any of the other study wells) in any subsequent sampling event. Similarly, chloroform was detected in the baseline event at only one well downgradient of the treatment area (MW-392A, 0.42µg/L), but was not detected at any other well, or during any subsequent monitoring event. While benzene is not associated with the Building 55 treatment area, residual benzene concentrations in groundwater in the vicinity of Building 55 may also be treated by the application of the soil amendment. Prior to excavation and soil treatment, benzene was reported at low concentrations at wells MW-255B (0.78 µg/L) and MW-256B (0.93 µg/L). At the one-month post-excavation monitoring event, benzene was also detected at wells MW-255B (0.94 µg/L) and MW-391A (5.6 µg/L). The benzene concentrations at wells MW-255B and MW-391A have dropped to 0.55 µg/L and 1.6 µg/L, respectively, in the January 2016 monitoring event. Additional monitoring will be necessary to confirm decreasing benzene concentrations at these locations.

2.4 ISCO Study Preliminary Conclusions

At this stage of the ISCO treatment program, the following conclusions can be derived:

• ISCO treatment progress continues to accomplish remedial goals for the on-site overburden groundwater; and

• Longer-term monitoring is essential to confirm the observed trends.

2.5 Proposed IA-1 Building 55 Area Next Steps

The proposed next steps are summarized as follows:

of 10

Continued Groundwater Monitoring:

• Continue to monitor groundwater quarterly through September 2017, in accordance with the PBR.

of 10

3.0 UPDATED SCHEDULE In accordance with the PBR, the anticipated 2016-2017 ISCO Treatment Program implementation schedule is as follows:

• April 2016: 7-months post-injection groundwater sampling event;

• July 2016: 10-months post-injection groundwater sampling event;

• October 2016: 13-months post-injection groundwater sampling event;

• January 2017: 16-months post-injection groundwater sampling event;

• April 2017: 19-months post-injection groundwater sampling event;

• July 2017: 22-months post-injection groundwater sampling event;

• September 2017: 25-months post-injection groundwater sampling event

As discussed earlier, a compilation of the groundwater sampling results generated from the entire ISCO program and a detailed evaluation of the remedial performance/progress and conclusions with respect to achieving the remediation goals of the ISCO treatment program will be presented in a subsequent submittal.
