Additionally, Department for Environmental Protection (DEP) staff and staff from other agencies conduct inspections on reported, unreported and pre-law water wells, and springs. The information provided to Division of Water (DOW) includes well or spring owner information; location information about these sites; and analytical data from samples collected after well installation, and during well inspections and spring inventories.
Submitted well construction records are reviewed for compliance with state well construction regulations. Well inspection, spring inventory and analytical data are also reviewed. Upon review, section staff compile the data provided and these data are then scanned electronically and maintained in the DEP Consolidated Groundwater Database (GWDB).
Staff members are then able to assemble and analyze data from these databases to make assessments concerning the quality of the groundwater resources throughout the state. They also perform extensive mapping of well and spring locations and wellhead protection areas throughout the state on U.S. Geological Survey 1:24000 topographic maps. Wells, springs and wellhead protection
areas are also mapped electronically.
The GWDB currently contains data on more than 76,000 wells and springs located throughout the Commonwealth, with approximately 3,000 additional wells and springs being added to the database annually.
