Greenfield Township Municipal Authority

ARM has assisted the Greenfield Township Municipal Authority (GTMA) with the development of a 350 gpm (~0.5 MGD) groundwater supply well drilled and constructed in the Ridgeley Sandstone Member of the Old Port Formation.

• Well siting included the use of an electrical resistivity (ER) geophysical survey and geologic mapping. 
• Well drilling and construction was done using a dual-rotary drilling rig and included the placement of a wire-wrapped, stainless steel, telescoping well screen to ensure the integrity of the well. 
• Aquifer testing has been conducted in accordance with a PADEP- and SRBC-approved testing plan. 
• Aquifer testing was successfully performed, including PADEP New Source sampling/analyses as well as Microscopic Particulate Evaluation sampling/analyses. All results were favorable for permit approval and development.
• Approvals were received from both the SRBC and the PADEP for a 0.5 MGD groundwater withdrawal.
