Nitrates in Rural Groundwater Not From Farming; An Unexpected Finding Based on Forensic Geochemistry

Sharptown is located in an agriculturally dominated portion of the Delmarva Peninsula of Maryland. Groundwater quality compliance samples have reflected elevated nitrate concentrations for years. Non-point agricultural sources were thought to be the source of the nitrates, but a detailed study as part of an updated Source Water Protection Plan assessment has now revealed a differing and surprising nitrate source interpretation, for which implementing a remedy is much more feasible. During this session you will apply geochemical analysis to water quality compliance data and observe the use of environmental tracers for identifying water contamination sources.
