Abstract Details

2009, Master of Environmental Science, Miami University, Environmental Sciences.
Elevated nitrate concentrations have been reported from municipal drinking water wells in the Twin Creek watershed in southwest Ohio, where residents depend on ground water as the sole drinking-water source. The extent and spatial and temporal distribution of contamination were investigated with ground water and surface water samples collected in April and July 2008. Nitrate sources were identified using 15N-NO3 and 18O-NO3 isotope analysis. Nitrate concentrations in ground water had relationships to well distance to surface water and buried valley aquifers. A mix of ammonium fertilizer and animal waste were the primary sources of nitrate contamination in the watershed. Elevated nitrate concentrations were not widespread in ground water but were found in ground water samples from buried valley aquifers and surface water. Residents of the watershed can control nitrate in well water by reducing agricultural activity around the wells or by using an appropriate point-of-use treatment system.
