Nutrient sources in suburbanizing watersheds

Changes in water quality are associated with shifts in land- use changes from forested or agricultural to high-density suburban.  With researchers from USGS and DNREC, we are characterizing groundwater chemistry at a site in southern Delaware that has changed from agricultural to suburban over the last 30 years. This site is located in the watershed of the Inland Bays, which have significant problems associated with eutrophication driven by delivery of groundwater-borne nutrients.
