Surface Water Remediation: Evaluation of Sediment Technologies

The Evaluation of Sediment Technologies Project

BACKGROUND

The USDOE and it’s contractors, the regulatory community, and public have placed high priority on the mitigation of the release of contaminated surface water and sediments from the PGDP. There are presently a number of industry-standard engineering approaches that have been applied at the PGDP to address releases of contaminated surface water and sediment from industrial and environmental restoration activities. However, those engineering approaches generally involve large expenditures of capital resources and significant time frames for implementation. Recent work conducted by the University of Kentucky Agricultural Engineering Department has identified, implemented and monitored cost and time-effective methods for controlling releases of contaminated surface water and sediments from agricultural, industrial, and mining sites. This project will focus on identifying readily implementable and cost effective surface water and sediment release control technologies that address surface water release pathways at the PGDP. Performance modeling that accounts for the range of industrial and meteorological conditions encountered at the PGPD will be conducted to ensure the appropriateness of remedial recommendations.

GOALS

  1. Evaluate the adequacy and performance of existing surface water controls
  2. Identify areas where surface water and sediment release controls should be implemented
  3. Identify appropriate cost and time effective surface water/sediment release control methods for # 2 above
  4. Conduct performance modeling for # 3 above

OBJECTIVES

  1. Review of existing data that is expected to consist of meteorological (rainfall, evaporation and possibly wind speed and direction)
  2. Review of existing site maps including topography and watersheds
  3. Review of current runoff and water quality data for outfalls 011, 008, and 015
  4. Review of current control systems (channels, pond(s), by-pass, etc.) for the outfalls 011, 008, and 015
  5. Prediction of hydrological response (rainfall-runoff) for current conditions
  6. Assessment of the performance of the current control system with respect to runoff, sediment and selective water quality constituents
  7. Conceptual design of alternative control systems for both long term and short term conditions
  8. Conceptual design of alternative controls systems in support of field assessment project associated with outfall 011
