Sediment samples were collected from Area 3 of the Field Research Center (FRC) in Oak Ridge, TN which lies adjacent to the former S-3 waste-disposal pond. Sediment samples were collected using a 1.5” diameter sediment sampler. At the surface, sample casing was removed, and samples were aseptically collected from the inner sections of the core using a sterile plastic scraper. Porewater nitrate was determined using an electrical conductivity detector on a Dionex™ ICS-5000+ series system (ThermoFisher Scientific, Waltham, MA) with an IonPac AS11HC analytical column. Soil pH was determined by EPA method 9045D.
