Welcome

The Geophysical Society of Pittsburgh is a nonprofit organization dedicated to promoting the science of geophysics in the Appalachian Basin. We are an official section of the Society of Exploration Geophysics (SEG).


Bi-monthly meetings are generally held from September to May on the first Tuesday of each month at various locations around the Greater Pittsburgh area. However, be sure to check the event calendar as exceptions to this rule occur often. All interested parties are encouraged to attend.

February Meeting


Shallow Geologic Characterization Wells in Tioga County, PA –Determining Deepest Freshwater in a Fractured Bedrock Environment

Presented by: Thomas A. Bardol, Advisor, Geology


Over the past three years Seneca Resources has undertaken an effort to better understand the shallow subsurface in our Tioga County development area. Tioga County has a structurally complex shallow subsurface due to erosion and loading from multiple periods of glaciation and from the effect of large salt-driven tectonics related to the Alleghenian Orogeny.This has led to shallow subsurface fluid flow that is dominated by fractures.


Part of this renewed effort is our Geologic Characterization Well (GCW) program that allows for a more robust interpretation of deepest freshwater. Much of this program is modeled off similar projects undertaken by the DCNR and USGS at their Cherry Flats, Gleason, and LaPorte test holes in Tioga and Sullivan Counties. This presentation will cover a review of those government projects, an overview of our drilling and data collection processes, and how we integrate that data to make informed decisions regarding freshwater protection.


When: Tuesday, February 11th, 2025

Where: Seneca Resources Auditorium, 3000 Westinghouse Dr., Suite 105, Cranberry Twp., PA 16066
