Optimizing Post Remediation Groundwater Performance with
Enhanced Microbiological Analysis
Authors: Joshua Orris, Antea Group USA and Jack Sheldon, Antea Group USA
Session: G2
Group: #1
INTRODUCTION APPROACH
RESULTS AND
CONCLUSIONS
Case Study:
Former specialty chemical manufacturing facility located New Jersey was actively undergoing investigations and remediation
since the late 1990’s.
• Chlorinated volatile organic compounds (CVOCs); 1,1,1–
trichloroethane (TCA), trichloroethylene (TCE) and their respective
degradation products were identified as primary Chemicals of
Concern (COCs)
• An Interim Remedial Measure (IRM), groundwater recovery and
treatment system was operational from 2001 to 2006 designed for
hydraulic control
• A unique strain of dehalococcoides were identified during bench
scale testing that were naturally degrading CVOCs at a low pH
range of 5.8-6.0
• Significant concentrations of both Biotic and Abiotic degradation
products had been detected in groundwater samples
• August 2002, a microbiological bench scale study was completed to
evaluate the potential for anaerobic biodegradation, specifically
reductive dechlorination to occur
August 2002 Bench Scale Results
• Confirmed anaerobic conditions along with elevated Chloride concentrations were detected at select monitoring wells
suggesting prior CVOC reduction had occurred
• Low concentrations of chloroethane and a lack of preferable organic acids indicated that the microbial degradation of TCA
was limited by a lack of nutrients
• Abiotic breakdown product pathways of TCA to Vinyl Chloride were detected
• Hypothesis: if sufficient nutrients were provided it was likely that the abiotic degradation of TCA would decrease and the
anaerobic biodegradation of TCA would increase
• Elevated concentrations of 1,1-DCE, the abiotic breakdown product, were detected; but with lower concentrations of Vinyl
Chloride, which is the biotic byproduct of 1,1-DCE. This conditions suggested that the microbial degradation system was
nutrient limited
HRSC—MiHPT
Enhanced Pilot Tests & Full Scale Design:
• Borehole geophysics completed in bedrock open borehole injection wells and existing
groundwater monitoring well network
• Leveraged data visualization with development of a 3D-Conceptual Site Model (3DCSM)
• Co-Injection application of Emulsified Vegetable Oil (EVO) and zero-valent iron (ZVI) delivery for
enhanced dechlorination biodegradation
• Enhanced targeted injection well design for pneumatic fracturing and injection that yielded
increased Radius of Influence for contaminant treatment
• Successful pilot testing resulted in a broader pneumatic injection full scale application of EVO/
ZVI
• Due to the efficiently targeted injection design, the groundwater Pump and Treatment system
was permanently shut-down and decommissioned resulting in a cost savings of $180,000 per
year
• Accessible source areas were removed during facility renovations and expansions in 2007 and a supplemental source area that was
delineated with High Resolution Site Characterization (HRSC), MiHPT was removed and treated with EVO/ZVI prior to backfilling to
accelerate treatment of contaminated groundwater present within the perched and intermediate upper bedrock
• Excavated contaminated materials were treated onsite with a patented process called Mobile Steam Distillation by EVO Corporation
3D-Conceptual Site Model
Excavation of Source Material
Pneumatic Injection Manifold Mobile Steam Distillation treatment
Post Remediation Monitoring:
• Optimized Monitoring Well Network
• Sampling & Analysis Plan included: CVOCs, organic fatty acids,
dissolved gases and QuantArray® - Chlor by Microbial Insights to
quantify key microorganisms (e.g. Dehalococcoides, Dehalobacter)
and functional genes (e.g. vinyl chloride reductase, methane
monooxygenase etc..) to assess potential for reductive
dechlorination and aerobic co-metabolism of CVOCs
QuantArray®- Chlor
Microbial Population Summary
Enhanced Post Remediation Monitoring:
• The site’s remedial strategy remains aligned with Monitored Natural Attenuation in association with dechlorination
• In 2022, the FIRST commercial application of MetaArray by Microbial Insights was performed at the site
• MetaArray utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that
reductive dechlorination is active or even that is slowing
• The results of MetaArray analysis identified groundwater
monitoring wells with a 80% confidence that were characterized as
either Limited for Reductive Dechlorination or had a High Reductive
Dechlorination potential
• The results of MetaArray will be used to further optimize the site’s
post remediation monitoring program for natural attenuation
