  <dc:description>&lt;p&gt;Hydrologic data for the Potomac Formation in New Castle County, Delaware, consist of records of historical ground-water pumpage, water levels, water quality, and surface-water discharge. This report includes records of 405 wells and hydro-graphs of water levels in 86 wells. Pumpage from 20 well fields is reported. Also included are stream-discharge hydrographs for 6 stations for water years 1979 and 1980 and historical low-flow measurements for 22 stations. &lt;/p&gt;&lt;p&gt;In the analysis of 23 aquifer tests, transmissivity and storage coefficient values for the Potomac Formation range from 454 to 8,480 feet squared per day and 3.8X10-3 to 5.6X10-5, respectively. Vertical hydraulic conductivities of the confining bed range from 0.0083 to 3.2 feet per day.&lt;/p&gt;</dc:description>
