【 摘 要 】

In a May 1995 inspection of the WIPP-site Exhaust Shaft indicated that water was seeping through the shaft's concrete liner at depths of 50 to 85 feet below ground surface. In March 1996 a catch basin was installed at the base of the Exhaust Shaft to intercept and prevent fluid from entering the repository horizon. Analyses of fluid samples collected from the catch basin indicated that some samples had concentration levels that exceeded U.S. Environmental Protection Agency (EPA) toxicity characteristics for lead under Title 40 Code of Federal Regulations (CFR) {section} 261.24. Ventilation system operations, weather conditions, and seepage into the Exhaust Shaft have resulted in operational problems. First, increased moisture in the shaft has affected air filters on sampling probes located near the top of the Exhaust Shaft, thus preventing analysis of air samples. Second, production of fluid in the shaft reporting to the catch basin created a disposal problem of the fluid which has been classified as a hazardous material under 40 CFR {section} 261.24 for lead. Though these problems do not effect the stability of the shaft they are a nuisance in that they increase operational costs and impact operation of the Exhaust Shaft air-monitoring system.
