This compilation brings together groundwater observations from Bradford County, Pennsylvania, held in Shale Network as of May 2018. It accompanies Wen and colleagues’ 2018 study of groundwater chemistry in a region of Marcellus Shale development.

May 2018 identifies the compilation, not the sampling period. The dataset is a defined subset of Shale Network records and does not represent every groundwater analysis in the county. Read the repository metadata and article for dates, methods, and the basis for interpreting water-quality patterns.
For methods and interpretation, see the associated Wen et al. (2018) study.
