View Groundwater records online

Viewing records online allows you to enter search criteria, and to export the results as a comma separated value file that can then be imported into most database and spreadsheet software packages. The online search contains only well data, and does not include all of the fields of data submitted though the years. For more complete information, refer to the Microsoft Access file below.

Download PaGWIS data in MS Access 2000 format

The statewide PaGWIS file must be downloaded and viewed with Microsoft Access. The Access database includes queries and forms that allow you to perform searches similar to the online record searches. The statewide database uses the same dataset of water wells as the online search; however, the Access database has additional fields for water-well records and also contains additional data on springs, spring-water quality, and well-water quality. With Access, the user has the added advantage of being able to modify queries for specific data extractions.

 

General Information

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. These paper records, and a small number submitted after 2009, have not been entered into PaGWIS.  See below for information on obtaining scans of well records submitted on paper forms that have not yet been added to PaGWIS. About 50,000 paper well records from this generation are being added to PaGWIS. 

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.

Scans of well records submitted on paper forms are available by contacting the Survey. Efforts are underway to add about 50,000 scanned records into PaGWIS. As of December 1, 2014, skeletal data and report images for over 17,000 of these records have been added. Requests for records of specific municipalities may be answered through email. Requests for large areas may require the purchase of a CD or DVD. 

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 440,000 records in PaGWIS. Over the years, many water well completion reports have not been submitted.
