Master's Projects and Capstones
Nitrate is one of the most common contaminants in groundwater and causes multiple health impacts when consumed. Contamination is most significant in agricultural areas and has increased steadily since the 1950s with the introduction of nitrogen fertilizers. The depth of an aquifer, sediment type, hydrogeology, redox conditions, microbe activity, fertilizer application, natural nitrogen deposits, and well construction influence the degree of nitrate contamination of an aquifer. The sources of nitrate pollution are fertilizer, manure, concentrated feeding lots, natural nitrogen deposits, atmospheric deposition, septic systems, wastewater treatment plants, and industrial activities. Nitrogen compounds applied on the surface are stored in the …
