Abstract:

This report presents a long-term ground-water monitoring program and ground-water extraction system performance monitoring and evaluation program developed by the U.S. Geological Survey during 1999-2000 in support of the remedial action conducted at the Former Nike Missile Battery Site Nike Site, Edgewood Area, Aberdeen Proving Ground, Maryland. Concentrations of trichloroethene at the Nike Site ranged from below the Maximum Contaminant Level of 5 micrograms per liter to 299 micrograms per liter during the Remedial Investigation under the Comprehensive Environmental Response, Compensation, and Liability Act program. The long-term monitoring program utilizes six selected monitoring wells that surround a trichloroethene contaminant plume. These wells will be monitored for five years and then reviewed by Federal and State regulators to determine whether future monitoring will be required. The performance assessment plan was formulated from existing data and interpretations provided by the Remedial InvestigationFeasibility Study process and the 100 Remedial Design of the extractiontreatment system. A performance evaluation of the Nike Site extraction system partially fulfills the remedial action requirement to monitor ground water as stipulated in the September 1996 Record of Decision.
