EPA/ORD Groundwater Flux Study - Troutdale Reynolds Industrial Park
Citation:
Ford, R., S. Acree, AND R. Ross. EPA/ORD Groundwater Flux Study - Troutdale Reynolds Industrial Park. TRIP Project Update Webinar, Ohio, Cincinnati, October 29, 2018.
Impact/Purpose:
This study addresses the issue of assessing potential impacts of contaminated groundwater discharge on lakes, streams and rivers adjacent to hazardous waste sites. The study demonstrates use of hand-installed devices for collecting pressure and temperature data to calculate the direction and magnitude of groundwater flow. This information is used to guide selection for locations in surface water to evaluate impact and to evaluate the effectiveness of existing groundwater remedies. The tools and methods are useful to Regional/State project managers and environmental consultants tasked with implementing site remedial investigations and cleanup actions.
Description:
EPA/ORD is providing technical support to Region 10 to assess the extent of groundwater discharge to the Sandy River adjacent to the Reynolds Metals Company Superfund Site. Temporary monitoring devices have been installed within East Lake and the Sandy River shoreline to support evaluation of horizontal and vertical hydraulic flow gradients and seepage flux. Data collected during April-September 2018 has been analyzed and preliminary interpretations will be presented to site stakeholders via webinar.
