Information for Pennsylvania-Licensed Well Drillers

Pennsylvania-Licensed well drillers providing well-drilling services for a noncommunity public water system are expected to document all work activities associated with the project, so that DEP has information available to verify that the well source does not pose a threat to public health. A typical well-drilling project for a noncommunity public water system includes the following components: well-site selection, well drilling, well construction and development, pump testing and water-quality sampling, and well disinfection. Well drillers with experience in drilling wells for public water supply use should have the knowledge and expertise to adequality address any combination of the project components for a noncommunity water system well source.

For guidance on how to construct and test a well, the well driller should consult DEP’s Public Water Supply Manual, Part IV, Noncommunity System Design Standards, DEP ID: 383-2128-108 and DEP’s Noncommunity Water System Application, Module 1 – Groundwater Source, DEP ID: 3940-FM-BSDW0568a.

Documentation of Well-Drilling Activities

The Pennsylvania-Licensed well driller should provide the public water supplier with their Water Well Completion Report that is submitted to the Pennsylvania Geological Survey and completed versions of the Well Construction Demonstration Datasheet and the Well Risk Assessment Form both of which are part of Module 1. Details provided on these forms are similar to the information that is required under the Pennsylvania Water Well Drillers License Act (Act 610) which is implemented by the Pennsylvania Geological Survey. 

Module 1 provides documentation of the drilling and well-construction activities completed by the well driller on behalf of the public water supplier. Specifically, the Well Construction Demonstration Datasheet includes details on the following: well capping, casing and grout, drive shoe, well screen or open hole, pitless adaptor, discharge line, pump, well development and disinfection, well construction measurements (total well depth, casing depth grout depth, depth to pump intake, static water level, and screen or open hole length), and well driller information.

Documentation of Pumping Test Activities

Once the well is drilled, constructed, and properly developed, the well driller may be requested by the project applicant to conduct a pumping test to determine what pumping rate the well can provide for system demand. The pumping test operator should execute the test and complete the associated forms according to the instructions provided on the Pumping Test Demonstration Datasheets that are part of Module 1. The pumping test should be conducted on a properly developed well and the pump-depth setting for the test must be the same as the final depth setting in the finished well. The pumping-test operator will need to effectively measure water levels and monitor drawdown during the test to ensure water levels do not drop below the pump.
