RI9 Ground-Water Levels in Delaware January, 1962 - June, 1966

RI9 Ground-Water Levels in Delaware January, 1962 - June, 1966

This report deals with fluctuations in nine observation wells during the period 1960 - 1966. These wells are part of a state-wide ground-water monitoring network and are located in areas of little or no pumping. Eight of the wells respond to water-table conditions; the ninth well appears to reflect artesian conditions.
Although precipitation throughout Delaware was generally below average during the period covered by this report, annual average water levels declined very little in the wells reported on here. There is some evidence, however, for a lowering of water-table levels by three to four feet during the period 1960 - 1962.

RI8 Evaluation of the Water Resources of Delaware

RI8 Evaluation of the Water Resources of Delaware

At present, Delaware has an abundance of water for the foreseeable future, but is already faced with water problems in some municipalities. These can only be resolved satisfactorily through complete evaluation of the State's water resources and the establishment of a coordinated program of water management.

DGS issues report on well water quality survey

OFR48 Results Of The Domestic Well Water-Quality Study

The Delaware Geological Survey (DGS) at the University of Delaware has released a new technical report that documents technical aspects of an intensive survey, review and analysis of existing ground-water quality data obtained from samples collected from more than 200 shallow domestic and small public wells to determine the extent to which toxic and carcinogenic compounds are present in shallow ground water.
