Understanding Well Water Testing Results

A summary of the basic characteristics of your well is presented in the testing results. This information originates from one or more of the following sources: 1) Well completion reports submitted by the well driller to the Pennsylvania Department of Conservation and Natural Resources and stored in the Pennsylvania Groundwater Information System (PaGWIS), 2) Records of field-located wells from a U.S. Geological Survey (USGS) database made available in the PaGWIS, 3) Water-well completion records provided by you or the previous land-owner, and(or) 4) Information collected by the USGS before or during the time of water-sample collection.
