Investigations of Subsurface Hydrocarbon Contamination

Blackshare Environmental routinely conducts investigations of subsurface hydrocarbon contamination, usually resulting from USTs, for the Oklahoma Corporation Commission and/or municipalities. These investigations are often done as part of larger road construction widening projects. These involve the installation of soil borings on monitoring wells, collection of soil and groundwater samples, analysis and completion of an Oklahoma Risk-Based Corrective Action (ORBCA), site remediation and closure activities including but not limited to disposal of auger cuttings and purged well water and plugging of all wells. Utility trenches are located and evaluated as well, as they are often pathways for contaminants to travel and impact other properties.
