Major Historical Delays

Procurement Delays:1. ARCADIS contract ended December of 2014; Contracts awarded in

summer of 2015

2. MOD to EA contract took about 15 months after the 5 Year Review came out.

Disputes between Army and USEPA: Formal and Informal

1. No risk –No ARAR Dispute: Almost 4 year delay for FS of 100 plus sites

2. Midvalley Groundwater Dispute

3. 5-Site Dispute

Ted Gabel


Still Waiting on EPA reviews:

• 45 Site Group A, B, C and D Proposed Plan (PP), • PICA-111 PP, • Picatinny Lake PP, • RI Report for EEGPB, • Proposed Plan for Lake Denmark - Off-Post,• Multi-Site MMRP Feasibility Study (FS), • Mortar and Skeet PP, • Multiple annual reports and multiple evaluation reports

Ted Gabel

Factors Driving the Current Situation • EPA has told us that EPA is ‘limited’ to signing 2-3 RODs/yr;

Only one ROD signed FY 19.

• ECC and Army had required 17 RODs by June of 2020 when ECC contract ends:

• Contract Officer determined there is not enough time to conduct the 3 of the 4 remediation tasks.

• Cannot have two contracts doing the same thing. A line must be drawn.

Ted Gabel

ECC Contract ModificationECC responsible only for:• Final Record of Decision for 600 Hill Record of Decision (COMPLETED although must be PN)• Proposed Plans to be Public Noticed:

Update on PFAS Investigations

RAB MeetingSeptember 26, 2019

Ted Gabel

Per-and Polyfluoroalkyl Substances

• PFAS are man-made, not naturally occurring, compounds, which include PFOA and PFOS

• Used since the 1950s in many products• Since 1970s, used by DoD in fire-fighting foam• Persistent in environment and found throughout the world• Widely detected in people, wildlife and fish• EPA set lifetime health advisory level of 70 ppt in drinking

water in 2016 for PFOA and PFOS (One ppt is the equivalent of one grain of sand in an Olympic-size swimming pool.)

• NJDEP groundwater remediation standards for PFOA and PFOS not yet promulgated

Ted Gabel

Short Timeline of Events

• Drinking water sampling conducted on Picatinny Arsenal drinking water wells in February and March 2018 identified PFOS and PFOA at concentrations which exceeded the EPA LHA level.

• Picatinny Arsenal water consumers were provided with alternate water for drinking and food preparation until appropriate steps were taken to reduce PFOS and PFOA to acceptable levels in the drinking water supply

• Quarterly sampling of drinking water wells and POE since hookup have all showed levels below any level of concerns.

Ted Gabel

American Water installed a Temporary Granulated Activated Carbon System

• The treatment system is comprised of two 20 ‘ high x 10’ wide vessels in series filled with a coconut shell based carbon media.

• Water in contact a minimum of 20 minutes per NJDEP regulations. The GAC absorbs PFCs, chlorinated and pumped into the distribution system.

• Performance testing and sampling was conducted and continues on a quarterly basis

• Units will be in operation for a period until permanent solution is found for the new water treatment plant at Picatinny Arsenal.

Ted Gabel

Water Treatment Construction

• Pad for Permanent Carbon treatment facility completed• Tank delivery in November• System operational next year

Ted Gabel

Preliminary Assessment Report

• Final PA submitted in April 2019

• Two potential sources of PFAS at Picatinny

• Aqueous film forming foam (AFFF) used to fight fires

• Mist suppressants used during metal plating

• 10 Areas of Potential Interest (AOPI) identified in PA

• Purpose: To evaluate the implementation and performance of the remedy in order to determine if the remedy is or will be protective of human health and the environment.

• Recommendations for optimization from the 2016 Fifth Five-Year Review for RAO-LTM sites incorporated into new scope of work for EA o Evaluation of Area D (PICA-076) Permeable Reactive Barrier (PRB) performance

o Evaluation of chlorinated volatile organic compound (CVOC) concentrations upgradient of the Area D PRB

• Area D Study Goalso Answer the question: Will the PRB work in the near future?

o Should the Army do something to reduce the timeframe of MNA cleanup?

Area D PRB & Upgradient CVOC Evaluation• Contamination Source: Building 24 - plating

facility that operated from 1960 to 1981

• Selected remedy: Permeable Reactive Barrier to intercept groundwater flow and monitored natural attenuation

• Remedial Strategy Data Gaps:

o Concentrations in deep unconfined wells downgradient of the former source not delineated

o Additional investigation of potential residual source needed to address elevated CVOCs and reduce overall mass flux to the PRB

o Increase in TCE concentrations southwest of the PRB

UNCLASSIFIED5 of 21


Area D PRB & Upgradient CVOC Evaluation• PRB Evaluation

o Performed in situ screening using a hydraulic profiling tool (HPT)

o Collected in situ groundwater samples near the PRBo Installed one CMT well (4 ports)

adjacent/southwest to D-PRB-09o Collected soil cores from within the PRB to visually

inspect for biofouling/silting; collect VOC sampleso Conducted comprehensive sampling/gauging evento Collected surface water samples from Green Pond

Brook

• Upgradient CVOC Concentration Evaluationo Installed two transects of 5 boreholes eacho Used HPT to provide horizontal and vertical

delineation of TCE in areas upgradient/downgradient of D-92-3

o Installed 3 CMT wells (7 ports at different depths in each)

o Collected biological reductive dechlorinationparameters in 6 wells

o Collected microbial samples from 3 wells to assess the available microbial community structure

Next Steps

• Preparation of Focused FS to include:o Evaluation of analytical results and PRB effectiveness

o Use HPT data (relative hydraulic conductivity) for targeted treatment

• In Situ Bioremediationo Groundwater model to project TCE reduction

timeframes and reduce the mass flux to the PRB

• Sediment, surface water, pore water, and soil sampling for explosives.

• The sampling design was intended to identify any residual/current explosive source areas remaining onsite as well as to determine if contaminated groundwater is discharging to Picatinny Lake and impacting associated surface water and sediment.

Group 1 TNT & RDX Evaluation

• 2018 Results Summary:o TNT

• TNT was not detected in surface water or pore water although exceedances of TNT SCLs in groundwater were reported during the 2018 annual groundwater sampling event.

• TNT was detected under the SCL in soil samples taken from Sites 40 and 157, and above the LOC at one sediment location at each site.

o RDX• RDX was detected in surface water and pore water but not

sediment.

• Six of 10 groundwater wells sampled during the 2018 annual groundwater sampling event reported SCL exceedances for RDX.

• The only RDX LOC exceedance found in any surface water, sediment, pore water, or soil sample collected under this effort was a surface water exceedance at sampling location 79PL-09.

• Groundwater Remedy Performanceo Pore flushing models discussed in the 2014 Monitoring

Report (ARCADIS 2014) suggested that the MNA duration was 30 to 40 years.

o Updated with data as of August 2018, it is estimated that groundwater restoration will be achieved between 7 to 18 years from 2019.

• Groundwater Recommendations:o Upon the collection of two more years of post-remediation

data, restoration timeframe assessments through both methods be re-evaluated.

o If re-evaluation of the timeframes indicates that post-remediation concentrations are not degrading as predicted, implementing anaerobic bioremediation through the injection of TNT- and RDX-degrading microbial cultures into plume groundwater could further stimulate reducing conditions and accelerate the MNA timeframe.

Group 1 TNT & RDX Evaluation• Additional sediment sampling at

6 locations to further delineate elevated detections at 79PL-01SD and 79PL-09SD (Sept. 2019)

• Evaluation Report and CSM will be updated based on results of additional sampling

• Current recommendations include:

o Additional action is not warranted for explosives in pore water or soil.

o Surface water and sediment will be monitored for the duration of the groundwater response action; however, SCLs were not established for these media.
