Remediation System Design
Creek Run has designed and installed numerous remediation systems to address soil and groundwater impacted by petroleum hydrocarbons, volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), light non-aqueous phase liquids (LNAPLs – free product), and heavy metals. Based on a thorough understanding of soil properties, contaminant distribution, and hydrogeologic conditions gained during subsurface investigation activities, Creek Run evaluates a variety of remedial approaches to identify the most appropriate remedial method(s) for addressing site-specific conditions and achieving regulatory closure at minimum cost.
If active remediation is warranted, Creek Run will conduct pilot tests to identify the most effective remedial method and acquire information needed to design a full scale remediation system. Pilot testing typically involves installation of test wells, followed by field tests ranging in duration from a few hours to several days. Data gathered during pilot testing is evaluated to assess contaminant removal efficiency and equipment requirements for a full scale system. Creek Run has extensive experience in pilot testing, test interpretation, and full scale system design for the following remedial methods: air sparging, soil vapor extraction, dual and multiple phase extraction, bioventing and biosparging.
Creek Run routinely performs aquifer pumping tests, slug tests, and soil permeability analyses to quantify basic soil and bedrock properties that control groundwater flow and contaminant migration. During remedial feasibility testing, Creek Run has utilized GFLOW groundwater flow modeling software to simulate the effects of groundwater extraction and infiltration of treated water. Commercially available fate and transport modeling software has been utilized to quantify exposure risks by predicting the rate of contaminant migration and degradation at several petroleum-impacted sites.
