Sixty-eight percent of the nitrogen that ends up in the Great Bay Estuary originates from sources spread across the watershed rather than direct discharges from point sources, such as municipal wastewater treatment facilities (DES, 2010; PREP, 2013). These sources of nitrogen are called non-point sources and consist of atmospheric deposition, fertilizers, human waste disposed into septic systems, and animal waste. The purpose of this study is to determine how much nitrogen each non-point source type contributes to the estuary. The nitrogen loads from municipal wastewater treatment facilities have been reported elsewhere (DES, 2010; PREP, 2013) and, therefore, are not included in this study except to provide context.
