Summary:

Major Findings: 1) Many contaminants in groundwater have geologic sources, but geochemical conditions control whether or not those contaminants dissolve and move through groundwater 2) Concentrations of nitrate and bacteria--the main drinking-water contaminants with human sources--were high in carbonate-rock aquifers and frequently exceeded human-health benchmarks 3) Large contributions of nitrate and phosphorus from groundwater to streams have a negative effect on ecological health of estuaries, such as the Chesapeake Bay and Albemarle-Pamlico Sound.
