Leachate Testing of Hamlet City Lake, North Carolina, Sediment
Abstract
Sediment leaching studies of Hamlet City Lake, Hamlet, NC, were conducted in laboratories at the U.S. Army Engineer Waterways Experiment Station. The purpose of these studies was to provide quantitative information on the potential for leachate impacts on groundwaters if dredged material from Hamlet City Lake were placed in a confined disposal facility (CDF) or under disposal conditions similar to land-farming. The study involved three elements: batch leach tests, column leach tests, and simulations using the Hydrologic Evaluation of Landfill Performance (HELP) model. Batch tests were conducted to determine intrinsic leaching characteristics of solids in Hamlet City Lake sediment. Column tests were conducted as a physical analog of continuous flow leaching in a CDF. HELP model simulations were conducted to simulate the generation of leachate by infiltration and to evaluate the relative effectiveness of a disposal site liner. Results of this study showed that, under disposal conditions similar to land-farming, organic contaminants such as polycyclic aromatic hydrocarbons (PAHs) and total recoverable petroleum hydrocarbons (TRPHs) will decrease in concentration as the result of volatilization and or biodegradation.
