Science activity

This project aimed to characterize the sources of carbon, nitrogen, phosphorous and sulfur compounds from wastewater treatment plant and agricultural discharge in the region. Stable isotope measurement provides elemental signatures that can be used to trace compounds to their sources. Use of this methodology requires that researchers first characterize the stable isotope composition of sources—or fingerprint the suspects. By determining the stable isotope composition of various compounds in wastewater and agricultural drainage sources, this project aimed to build a better understanding of how these compounds are affected by different wastewater treatment agricultural land use practices. In addition, the project has provided a base of knowledge to better understand how these compounds are transported and taken up in the delta environment.
