Hydrologic data for aquifers in Philadelphia, Pennsylvania

Abstract

Selected data on the ground-water resources of Philadelphia, Pennsylvania, are presented in this report. Information including water levels and data on aquifers is tabulated for 828 wells and 3 sumps. Chemical analyses are given for 1,467 water samples obtained from 205 sites and include 103 analyses for trace elements and 68 analyses for volatile organic compounds. An index of geophysical logs including gamma ray, neutron, caliper, fluid conductivity, fluid velocity, single-point resistance, spontaneous potential, and temperature determinations made-in 51 wells is also presented. Data-collection sites are shown on a 1:50,000 scale location map. DESCRIPTION OF AREAThe city of Philadelphia has an area of 134.6 square miles in the Piedmont and Coastal Plain physiographic provinces of southeastern Pennsylvania (fig. 1). The Piedmont lies in a broad area northwest of the Fall Line, whereas the Coastal Plain occupies a narrow band along the Delaware River. The Fall Line demarcates the landward edge of the Coastal Plain. CalendarWSP Calendar WSP Calendar WSP Year No. Year No. Year No.
