Water Supply
What WE Do
Taylor GeoServices (TGS) assists clients with finding and permitting source water supplies. Our hydrogeologists and licensed geologists have worked with clients on large residential developments, industrial supply, municipal systems to local water supplies. When added to your team, you get a knowledgeable staff able to work within the regulatory framework and river basin commissions, combined with the ability to characterize the aquifer and obtain a sustainable supply of water.

Municipal Water Supply
Shrewsbury, York County, Pennsylvania
Taylor GeoServices (TGS) staff provide technical geologic, hydrogeologic, compliance and operations support services to Shrewsbury Borough and have been responsible for developing all aspects of the geologic and hydrogeologic characterization work for the borough since 2010.
The borough is in a drought sensitive headwaters aquifer system underlain by Precambrian/Cambrian schist bedrock of the Wissahickon Formation. TGS utilized GIS to model possible production well locations. This work included fracture trace analysis, defining exclusion zones, and developing hydrogeologic criteria that would result in high yielding wells by evaluating topographic position, overburden thickness, and proximity to highly fractured zones and Triassic age metabasalt intrusion zones.
TGS assists the borough with re-permitting their production wells with the Susquehanna River Basin Commission. This work includes aquifer testing, well capture analysis, recharge and base flow analysis, and safe yield determinations. Numerical and analytical models have been developed for the project to evaluate the wells’ long-term yields of the wells and will be verified with long duration aquifer testing.
Community Water Supply System
York County, Pennsylvania
Taylor GeoServices (TGS) permitted the community water supply for a 220 residential community. The 98-acre property is situated on a bluff overlooking Codorus Creek and the Susquehanna River in central Pennsylvania. TGS geologists gained an understanding of the subsurface conditions. A fracture trace analysis was done to identify possible higher yielding well locations.
Drilled wells are logged and suitable water bearing zones were identified. An 8-hour step drawdown test assisted with evaluating specific capacity and potential yield used to design a longer term, constant rate pumping test. Data obtained from a 48-hour pumping test was then used to identify aquifer characteristics and an optimal and sustainable well yield. Water samples are collected during the pumping test for new source parameters.
Finally, a comprehensive report is prepared and provided to the regulatory agencies for review and approval. Three water supply wells were permitted for the community providing the needed 20 mgpy. TGS worked closely with the project engineer, subcontractors, and regulatory agencies to effectively complete the project on schedule and on budget.
