Client Challenge
A former refinery site had been dormant for decades when the owner, a global oil company, sought to prepare the property for sale. The property had widespread elevated concentrations of lead in surface soil resulting from historic oil-treatment processes. The potential presence of the Texas horned lizard, a threatened species, posed a significant risk to escalated remediation costs.
Client Challenge
Elevated concentrations of chlorinated volatile organic compounds (CVOCs) in soil remained in a former perchloroethylene (PCE) and trichloroethylene (TCE) storage area at a former chemical manufacturing plant. Achieving regulatory closure for this area of concern (AOC) under the RCRA Corrective Action program, with no further action determination in this AOC, required a targeted soil cleanup. GES was retained to evaluate potential remedial solutions and to implement a technical and cost-effective alternative.
Client Challenge
A US-based producer of oil and natural gas required establishment of a multi-state groundwater quality database to support their drilling operations. The massive five-state program was designed to meet regulatory and liability protection requirements. The company was challenged to manage and properly glean from data collected, as there were commonly multiple sources of parcel data and overlapping of parcels identified for sampling during different stages of the drilling program.
