The EPA had been reviewing data provided by three sources, Dimock residence, Cabot Oil and Gas, and the Pennsylvania Department of Environmental Protection. After finally completing the review, the EPA decided to deliver temporary drinking water to the four homes where data reviewed by the EPA indicated that resident’s well water contained levels of contaminants and posed a health concern. The cause of the contaminated water in Dimock, Pennsylvania is yet to be determined; although, some believe that hydraulic fracturing caused the contamination, others are unsure including the EPA. The EPA decided to take action and will be conducting extensive tests on the local water supply.

The sampling will begin in a matter of days and will take about three weeks to gather all the samples from the Dimock residence. The EPA expects results in about five weeks after all the samples are taken.

In addition to the EPA testing mentioned earlier, The EPA will develop a new waste-water treatment standard, and will conduct a national study on the potential impacts of hydraulic fracturing on drinking water sources. The EPA is aiming to reduce emission from hydraulic fracturing by 95% by eventually requiring green well completion.
