What The EPA Is Saying About Dimock’s Water Quality

Dimock, Susquehanna County is once again front and center in the debate over hydraulic fracturing today. Anti-drilling activists are descending on the community to protest the state Department of Environmental Protection’s ruling that Cabot Oil and Gas no longer has to provide water to Dimock residents whose water has been contaminated by methane.

(Behind on what’s gone wrong in Dimock? Here’s our primer.)

With Dimock’s water woes in the news, it’s worth taking a look at a letter the Environmental Protection Agency recently sent to the township’s residents. The conservative Heritage Foundation has blogged about the missive:

Dimock has become a lightning rod in the fight against the natural gas extraction technique hydraulic fracturing. Anti-natural gas activists have used the town in a years-long campaign to prevent the practice, which they insist contaminates drinking water supplies.

But the Environmental Protection Agency says otherwise. The EPA sent an email to Dimock residents informing them of the agency’s findings regarding the state of the town’s drinking water supply. “While we are continuing our review,” Community Involvement Coordinator Trish Taylor wrote, “to date, the data does not indicate that the well water [in Dimock] presents an immediate health threat to users.”

That finding supported claims by Cabot Oil and Gas, which has been sued by Dimock residents. A judge from the Pennsylvania Department of Environmental Protection recently ruled that Cabot had satisfied its requirements under the law to provide potable water to Dimock residents, and the company has announced plans to discontinue water deliveries.

EPA’s findings comport with administrator Lisa Jackson’s previous statements regarding the effects – or lack thereof – of hydraulic fracturing on drinking water. Earlier this year, Jackson told a House committee that she was “not aware of any proven case where the fracking process itself has affected water.”

StateImpact has seen the letter, too. A few things are worth clarifying:

    • The letter isn’t a final ruling on Dimock’s water issues. The EPA says it will “continue to review available information related to the concerns of Dimock area residents.”
    • EPA is not working off its own independent data here. Rather, it is reviewing and screening testing samples collected by DEP.
    • Finally, the EPA statement that water does not “present an immediate threat” is not exactly a full endorsement of the water quality.

So: the EPA letter is an indication that the situation is improving in Dimock. But it’s far from a federal seal of approval that the township’s problems have been solved. (StateImpact has left a message with the EPA coordinator who wrote the letter, and will update this post if and when he gets back to us.) Reporter Susan Phillips is covering the protests in Susquehanna County, and will provide updates later today.

    It seems like information indicates that Cabot requested the samples to be filtered PRIOR to any analysis. Bottom line is this is not conventional to do with drinking water samples and makes it totally infeasible to compare with any risk values. Cabot dropped the balls if this is correct.

    § 250.10. Measurement of regulated substances in media.
     (a)  For measuring regulated substances in soil and sediments, analyses shall be performed on a dry weight basis.
     (b)  For metals in soil, analyses shall be performed on total metals, except for hexavalent and trivalent chromium, which analyses shall be performed individually.
     (c)  For groundwater, samples for metals analysis shall be field filtered and field acidified in accordance with the most current version of the Groundwater Monitoring Guidance Manual, Department of Environmental Protection, 3610-BK-DEP1973.
     (d)  For groundwater where monitoring is being performed at a drinking water well, samples for metals analysis shall be field acidified and unfiltered in accordance with the most current version of Groundwater Monitoring Guidance Manual, Department of Environmental Protection, 3610-BK-DEP1973.
     (e)  For surface water, samples for metals analysis shall be field acidified in accordance with approved EPA analytical methods in §  16.102 (relating to approved EPA analytical methods and detection limits).
     (f)  For air, samples and analyses shall be performed in accordance with Chapters 131 and 139 (relating to ambient air quality standards; and sampling and testing).
