Project Highlight: Remediation of Chlorinated Ethenes in Fractured Bedrock

Historic groundwater data indicated high concentrations of PCE and degradation products TCE, DCE and VC. Remediation of this brownfield property needed to be completed on an expedited basis with a high probability of success due to retail redevelopment timeline. Cascade was contracted to properly characterize the site by maximizing the use of existing data and develop a site-specific conceptual site model (CSM). Pneumatic fracturing was utilized to enhance fractures to maximize ROI and contact.
