Well Siting

GeoServices, Ltd. has completed numerous well siting studies to identify areas that may be favorable for development of ground water resources. GeoServices can increase the probability of locating a well to achieve your desired yield.

Regional Ground Water Evaluation

The first step of a well siting study is to evaluate the regional geology and hydrogeology of the area. This includes the identification and consideration of the following:

  • Geologic formations that tend to be higher-producing aquifers
  • Potential contaminant sources
  • Large quantity withdrawals from the area to assess potential well interference
  • The impact of wetlands and species of concern on development of new wells
  • Zoning and current land use conflicts

Geologic formations and their properties are identified. Recharge rates applicable to each formation are included to demonstrate the relative availability of ground water for the area.

GeoServices searches several databases (DCNR, PaGWIS, SRBC, eFacts, and eMapPA) for existing wells and their yields to identify the impact of those wells on the study area. Identification of wetlands and species of concern is completed to identify any impact on well site development. Another database search is then completed to identify potential contaminant sites, which could impact well sites. Other assessments are made of zoning, current land use, and potential interference that future well sites may have on existing water supplies.

Well Siting Study

The purpose of the well siting study is to locate potential well sites to supply sufficient water to meet current and future water demands. A fracture trace analysis is completed on the study area. Fracture traces are linear features in fractured bedrock that often represent zones of higher permeability than are found in adjacent rocks.Fracture zones are potential pathways for enhanced movement of ground water, and wells drilled on those fracture traces are often more productive than wells drilled at random locations. Fracture traces are assessed using aerial photographs, high altitude photographs, on-line photos and light detection and ranging (LIDAR) images. A field survey is also completed to confirm the presence and strength of any features identified.

Well sites are chosen based on the fracture trace analysis and field investigation. The sites are ranked based on the strength of the features observed, the geology of the well sites, wellhead protection radius availability, potential contaminant issues and other factors. A recommendation is then made for the site that should be drilled first. Upon selection of a well site or well sites, a sanitary survey with the state regulatory agency is completed.
