Description: The lower Potomac confining unit is regionally continuous from North Carolina to New Jersey and generally ranges in thickness from 50 to 100 ft but exceeds 1,000 ft toward the mouth of Delaware Bay (Trapp, 1992). Vertical leakage generally ranges from 1 ´ 10-8 to 1 ´ 10-4 (ft/day) (Trapp, 1992). Pope and Gordon (1999) presented a map showing the leakage distribution of the lower Potomac confining unit across southeastern New Jersey, and this map is used for the GIS.
