Contaminated Soil Sampling Method
What is Contaminated Soil Sampling? Use of a proper contaminated soil sampling method is vital to obtain a representative sample of soil waste. A representative sample of soil waste is necessary to accurately characterize (hazardous or non-hazardous) your stabilized waste piles. If improperly conducted, valuable time and resources may be wasted by contractors, generators and consultants. The ...

BOS 200, Hydrocarbons Application at an Active Gas Station - Case Study
Abstract: Trap and Treat® BOS 200® was applied at an active gas station in Europe with elevated dissolved phase contamination and NAPL impacts to protect the primary aquifer and cut off the dissolved phase plume from migrating off-site. Over the course of 4.5 years of monitoring, 92.4-99.9% reductions in Benzene were achieved in the treatment area (replaced) monitoring wells. Validation ...

Economic returns from monitoring and remediation of acid soils with lime application - Case Study
A long term soil acidity monitoring study was conducted in the Gabby Quoi Quoi catchment located in the central agricultural region of Western Australia, measuring change in soil pH at GIS located sample points in 1999 and 2006. Of the 300 sites sampled, 75% of the topsoil and 85% of the midsoil sampled in 1999 had pH values < 5.0, with 15% of these soils having a pH value of < 4.0. Liming ...

Remediation of Diesel and Fuel Oil Hydrocarbons in High Clay Content Soils: A Field Comparison of Amendment Performance Conducted at the Mare Island Naval Shipyard
ABSTRACT Past practices at the now closed Mare Island Naval Shipyard in Vallejo, CA caused diesel and fuel oil range organic (DFRO) contamination of the soil. The high clay content of the soils makes any remediation effort especially challenging. Chromatography of methylene chloride extracts of Mare Island soil confirmed that little weathering or degradation of petroleum hydrocarbons had ...

Large TCE Plume with Extensive DNAPL - Case Study
ABSTRACT High density sampling program was key to remediation of soil and groundwater impacted by TCE DNAPL at a former industrial site underlain by river deposits and sedimentary bedrock. CHALLENGES Impacted alluvium consisted of poorly sorted, fine to coarse grained sand. The source area was underlain by an aquitard of silt and clayey silt where dense non-aqueous phase liquid (DNAPL) pooled ...
