WEB-BASED DATA MANAGEMENT SYSTEM FOR LONG-TERM PERFORMANCE MONITORING AND STEWARDSHIP OF A LOW-LEVEL RADIOACTIVE WASTE DISPOSAL FACILITY

摘要

A web-based data management system is described that is being used for long-term performance monitoring and stewardship of a low-level radioactive waste disposal facility (LLRWDF) at the Fernald Closure Project (FCP) in Fernald, Ohio, USA. The system provides integrated data collection and management for monitoring performance of the liner and cover systems in the LLRWDF. Integrated performance monitoring data (meteorological, hydrological, geophysical, ecological, leachate flow, and leachate quality data) are presented and compared with performance criteria and action levels in near real-time. A status summary is also included for the site manager, regulators, and other stakeholders to provide an early warning regarding the need for corrective action.
