For information about the Natural Gas drilling anomaly of Jan-Feb 2019, test results and other information from the time surrounding the event are available here.
The results below represent our natural gas completions (NG completions) sample results to date. We test before, during and for one month after a well completion event to ensure the water quality does not deviate from average background levels. For a complete list of analytes and methods, see NG completions analyte list. The results to date file will be updated periodically with new results as they are received from our certified lab.

GOVENOR'S MARCELLUS SHALE ADVISORY COMMISSION
STUDY FINDS NO PROVEN ADVERSE EFFECTS OF FRACKING
A study named Hydraulic Fracturing: Meeting the Nation’s Energy Needs While Protecting Groundwater Resources by the National Groundwater Association finds no “definitively documented” cases of widespread adverse water quality or quantity problems attributable to hydrologic fracturing by the oil and gas industry. The study is consistent with the 2013 AWWA white paper.
“Water and Hydraulic Fracturing” which found that there were likely to be no such impacts if fracking is done in accordance with state and federal standards and industry best practices. Like the AWWA report, the NGWA report stresses the importance of properly constructing wells, sealing abandoned wells, effectively managing water use and managing wastewaters at the surface.
Drilling Impact on Water Quality
IUP MAGAZINE ARTICLE
This section is intended to gather test results and other pertinent information from MAWC regarding the CNX Natural Gas drilling pressure anomaly at the Shaw 1G well on Jan-Feb 2019.
On August 20, 2020 DEP released information that it and CNX have reached a settlement of violations stemming from this incident.
CNX Shaw NOV letter
To date, all results indicate normal background levels of 179 substances and parameters tested for. Test results are posted below.
Prior to any deep well being fractured on MAWC property, weekly sampling of the reservoir begins a month before the commencement of hydraulic fracturing. This is to establish a baseline of water test results. Please see the maps below for sampling sites.
After receiving notice of the Shaw pad incident, MAWC commenced daily testing until CNX provided notice that the well had been successfully remediated. Testing continues three times a week.

WATER WELL TESTING
The PA Department of Environmental Protection has asked that questions about private water well testing be referred to Dan Counahan, Program Manager in Oil and Gas at 412 442-4006.
A CNX contractor contacted homeowners within a 1-mile radius around the conventional oil and gas wells that were flared during the event and offered to screen such wells to ensure there were no impacts. For questions, please call the DEP at the number above.
