Mercury assessment for water and sediment in Oak Ridge National Laboratory streams

DOI:https://doi.org/10.2172/6327522· OSTI ID:6327522
An assessment plan was implemented in compliance with the Clean Water Act and the Oak Ridge National Laboratory's (ORNL) National Pollutant Discharge Elimination System (NPDES) permit to identify, locate, and minimize all sources of mercury contamination in ORNL discharges to the aquatic environment. This plan was designed to identify sources of mercury from past operations and spills through a review of file records and personal interviews. A network of monitoring and sampling stations, based on knowledge of mercury deposits in receiving streams, knowledge of mercury discharges from pipes to streams, and a review of chemical data from previous contaminant surveys, was established for sample collection. The plan was designed to assess the potential for the metal reaching surrounding streams and rivers by placement of sampling sites relative to potential contaminant movement from areas of deposition. This summary report describes appropriate sampling and analytical procedures, defines the database management system, provides for chain-of-custody, Quality Assurance (QA), and presents contaminant concentration data for 1988. 11 refs., 3 figs., 10 tabs.
