Pennsylvania Groundwater Information System (PaGWIS)
Over the years, water well records that comprise the Pennsylvania GroundWater Information System (PaGWIS) have come from various sources, but most of the well records have been submitted to the Pennsylvania Geological Survey by water well drillers. Records submitted by drillers have been added to PaGWIS in various stages over the years, starting in 1969. The data entered varied somewhat with each generation of data entry.
Records originally entered into PaGWIS have latitude and longitude coordinates. These coordinates were determined by Survey staff by plotting the best estimate of the location of the well based on the written description of the well location and the sketch map included on the paper well record. The goal was for the coordinates of each well to be within one mile of its actual location. These records are included in the results of radial and polygonal searches. These records do not include the well address or the driller's log. There are no links to digital images of the paper records for these wells.
For years, no records were entered into PaGWIS because of insufficient staff, creating a backlog of 10 to 20 years, depending on the county. In 2005, skeletal data (owner name, well address, county, municipality, driller, and date drilled) for this backlog of about 152,000 records were entered into PaGWIS. No coordinates were entered for these records. Therefore, they will not be listed in the results of either radial or polygonal searches. You must search by county, municipality, driller, or date drilled to locate these records. Because these well records do not have all their data included from the paper forms, we have provided in the search results links to the images of the paper records submitted to the Survey. Upon selection, these links open in a new window where the original well record can viewed and printed.
After 2005, paper records continued to be submitted until electronic submittal by WebDriller became mandatory on June 1, 2009. Starting in 2009, drillers have used an online application called WebDriller to enter well records electronically. With WebDriller, data are transferred automatically into PaGWIS within 30 days after drillers "print for owner." These digital records have coordinates so that these reports will be included in the results of radial or polygonal searches. There are no images linked to these digital records.
Since October 2014, about 55,000 paper records have been entered into PaGWIS through a data preservation grant from the U.S. Geological Survey. Locations for 6,550 of these records were determined using internal applications and Internet information tools.
It's been estimated that Pennsylvania has over a million domestic water wells, plus an unknown number of monitoring and other types of water wells. Yet, there are only about 500,000 records in PaGWIS. Over the years, many water well completion reports have not been submitted.
