Abstract:

Anaerobically digested sludge from the TCA wastewater treatment plant is land applied, as a fertilizer, on TCA's dedicated sludge farms. This study was undertaken to investigate the possibility of this land applied sludge as a potential source of high nitrate concentrations in the groundwater. Analysis of nitrogen isotopes in nitrate in the groundwater samples demonstrated that commercial chemical fertilizers, as opposed to digested sludge, was responsible for the elevated levels of nitrate.
