Impact/Purpose:
Improve the scientific understanding of the processes controlling nutrient distributions in surface waters. Produce a suite of enhanced models for characterizing nutrient distributions in surface waters by incorporating improved process understanding in existing models (e.g., WASP), by developing new models (e.g., WHAM, reactive transport), and improving linkages between model components.
Description:
Samples were collected from one spring and one well that were selected to reflect agricultural impacts, and a spring and a well that were considered to show little to no evidence of agricultural impact. These samples were characterized for fixed N species and dissolved organic N. These analytes were monitored in the agricultural spring for up to two years along with other analytes that we reported upon previously.
