Natural Attenuation Software (NAS) Application and Demonstration Case Study

Remediation of Trichloroethylene-Contaminated Ground Water, Ash Landfill, Seneca Army Depot Activity, Romulus, New York
Data collected from monitoring a trichloroethylene (TCE) plume at an old landfill at the Seneca Army Depot Activity, Romulus, New York, is being used to evaluate the ability of the Natural Attenuation Software (NAS) package to estimate cleanup times associated with combining the remediation of a contaminant source-area with using Monitored Natural Attenuation (MNA) to remediate the remaining downgradient contaminant plume. This site is one of eight demonstration sites that make up a diverse set of geologic, hydraulic, and geochemical environments. The evaluation is being conducted by the U.S. Navy, Virginia Polytechnic Institute and State University (Virginia Tech), and U.S. Geological Survey (USGS), with funding from the Environmental Security Technology Certification Program (ESTCP).
