Author: Bryan R. Maurer 339 Haymaker Road Phone: 412-373-5240 Monitored natural attenuation is an increasingly common approach for managing organic contamination in groundwater at hazardous waste sites, particularly where no local groundwater users are identified and after source removal/reduction methods have been implemented. Under this scenario, residual contamination that poses no imminent threat to human health or the environment is allowed to degrade through naturally occurring physical, chemical, or biological processes. This paper describes the use of ArcView GIS and ArcView Spatial Analyst to develop a model for evaluating the potential occurrence of natual attenuation in groundwater at an NPL site in Mercer County, Pennsylvania, based on U.S. EPA and USAF guidance documents. |
