Key Points

This research aims to investigate the relationship between unconventional oil and gas development and groundwater quality in the Marcellus Shale region.
Targeted sampling of groundwater with a focus on brine signals
Comparison of water quality indicators with UOGD activity
Analysis of regional water quality data
Localized brine signals detected in groundwater samples
No significant regional water quality impacts linked to UOGD activities observed
Findings suggest a limited effect of UOGD on overall groundwater quality

Implication

Finds localized brine signals in groundwater, indicating minimal regional water quality impacts from UOGD.

Abstract

Unconventional oil and gas development (UOGD) in the Marcellus Shale of southwestern Pennsylvania has raised persistent concerns regarding groundwater quality. Previous work identified potential regional associations between UOGD activity and...
