摘要

Background/Objectives. Previous operations at a former industrial site have contributed chlorinated volatile organic compounds (CVOCs) (primarily trichloroethene [TCE] and carbon tetrachloride [CTC]) to a mixed, 60-acre plume. The source area plume exists in both the overburden and bedrock aquifers with the majority of mass transport from the site occurring through the fractured shale bedrock. General groundwater flow in bedrock occurs preferentially along strike within discrete intensely fractured bedding planes. However, natural source-area groundwater mounding in the overburden aquifer has caused both down-dip and up-dip spreading of the plumes in bedrock. A pilot enhanced in situ bioremediation program was implemented in the source area in both the overburden and bedrock aquifers. Due to the complexity of the fractured bedrock hydrogeology and multiple offsite sources contributing CVOCs; Environmental Visualization System (EVS) software was utilized in order to gain a better understanding of the bioremediation performance. EVS software uses advanced gridding and geostatistical analysis to create 3D models of geologic setting and analyte spatial data.
