PID values showed 94% reduction in the values of fumes below the slab while the carbon dioxide values showed continued bacterial activity during the process. As the soil beneath or ground water showed any contamination, the project was closed.
Ground Water Remediation Case Study
The Pine Street Barge Canal Superfund Site is located along the coast of Lake Champlain. Sediments in the canal were contaminated by historic dumping of various materials including coal tar, solvents and petroleum products. Terra Contracting Services, LLC (Terra) was retained to implement the remedial design. Terra subcontracted with Global Environmental Engineering Inc. (Global) to provide projectmanagement services to assure the project was constructed according specifications within the specified schedule and...
White Paper: Soil Data Quality Control
Why it is essential during a contaminated soil study? Before starting an evaluation of the contamination leading to decision-making tools for site clean-up, it is essential to ensure data quality. Thus, based on solid and reliable foundations, uncertainties occurring during the different steps of the decision process will be better controlled and the final quality of the project improved. The objective of this white paper is to assess at best the validity of the data through visual, statistical and geostatistical...
Bioswales reduce contaminants associated with toxicity in urban stormwater
Contamination and toxicity associated with urban stormwater runoff are a growing concern because of the potential for receiving system impacts. California water regulators are mandating implementation of green infrastructure as part of new urban development projects to treat stormwater and increase infiltration. Parking lot bioswales are low impact development practices that promote filtering of runoff through plants and soil. Studies have demonstrated that bioswales reduce concentrations of suspended sediments,...
Case study - Performance testing PAHs in soil
These case studies highlight Sitelab’s accuracy from customers who have used the UVF-3100D for testing Target PAHs. This test correlates well to U.S. EPA Method 8270 or similar GC methods, which includes a list of 16 or more compounds. The analyzer is fitted with special optical filters sensitive to this same group of hydrocarbons.Examples of UVF-3100D testing Polycyclic Aromatic Hydrocarbons in Soils vs. Certified Laboratories.

Case Study - Source Area Remediation of PCE in Soil - Fair Lawn, New Jersey
TRS Group, Inc. (TRS) was retained by Anderson Mulholland and Associates, Inc. (AMAI) to perform an Electrical Resistance Heating (ERH) remediation of DNAPL in soil at the former Topps Dry Cleaners property in Fair Lawn, NJ. The remedial goal of this project was a reduction of tetrachloroethene (PCE) in soil to less than 1 milligram per kilogram (mg/kg) in every soil sample. Final confirmatory soil sampling indicated that all soil samples were below 1 mg/kg PCE and average soil concentrations were reduced to less...
