Kingston Ash Recovery Long-term Monitoring

OAK RIDGE, January 2015 – ARCADIS US, Inc. and Restoration Services, Inc. (RSI) were jointly awarded a 5-year base contract, including options to extend the contract term for 3 additional years, by the Tennessee Valley Authority (TVA) to support the Kingston Ash Recovery Long term Monitoring (LTM) in Kingston, Tennessee.

LTM is being performed under the terms of an agreement with the U.S. Environmental Protection Agency and the Tennessee Department of Environment and Conservation to evaluate the success of Monitored Natural Recovery as the selected Comprehensive Environmental Response, Compensation, and Liability Act of 1980 action for remediation of residual fly ash in the Emory and Clinch Rivers near Kingston, Tennessee. Following a December 2008 spill of ash from a failed dredge cell at its Kingston Fossil Plant on the Emory River, TVA removed and disposed of several million cubic yards of spilled ash from the river system. RSI is responsible for sediment sampling, handling, and shipping; supporting tree swallow sampling, field observations, and data analysis; and supporting annual project reporting. RSI and ARCADIS have supported the ash recovery project and environmental monitoring for the previous 6 years since the ash spill occurred.
