This report reviews and provides recommendations for instituting a long-term groundwater monitoring network for Frontier Hard Chrome (FHC) Superfund Site in Vancouver, Washington. The FHC Site is a former chrome plating facility in the floodplain of the Colombia River. The current FHC groundwater monitoring network has been evaluated using a formal qualitative approach as well as statistical tools found in the Monitoring and Remediation Optimization System software (MAROS). Recommendations are made for groundwater sampling frequency and location based on current hydrogeologic conditions and long-term monitoring goals for the system. The primary goal of developing an optimized groundwater monitoring strategy at the FHC Site is to create a dataset that fully supports site management decisions while minimizing time and expense associated with collecting and interpreting data.You may need a PDF reader to view some of the files on this page.
