Storm-influenced concentrations of nitrate and three volatile organic compounds (VOCs) were determined at seven carbonate springs located on or near the Fort Campbell Army Base spanning the western Kentucky-Tennessee border. Nitrate concentrations varied considerably from spring to spring and generally were diluted during storm flow. VOCs identified in water included trichloroethene (TCE), perchloroethene (PCE), and chloroform, all at concentrations near the detection limit. Within analytical constraints, VOCs remained constant through storm hydrographs, although limited dilution may have taken place. Organic compounds were detected, however, in spring sediments, even when they were not detected in the associated water. Combining these results with previous work, we conclude that storm chemographs for nitrate and VOCs may differ from the more commonly studied carbonate parameters and that sediments play a key role in the storage of contaminants at springs.
