The EPA has completed well water sampling at 11 homes in Dimock this week.

The EPA says it is also bringing in a truckload of water to four families each day. Daily water deliveries will continue until the EPA gets a better idea as to how much water each home needs. These are moves that have stepped on the toes - so to speak - of the Pennsylvania Department of Environmental Protection and Cabot Oil and Gas. Late last year, the DEP agreed with Cabot that the water in Dimock is safe and Cabot could stop delivering water to a group of families who presumably had their wells contaminated by drilling operations.

However, the EPA says it's concerned with some of the results that the DEP and Cabot think are fine, so it's doing more testing. Trish Taylor says, "It's been reviewed for chemical compounds that we know are associated with drilling operations as well as heavy metals and organics in other compounds that we normally would look at to see if there were other potential health risks."

Water deliveries will continue at least for about another five weeks, until test results come back. The EPA is conducting split sampling with the DEP and Cabot as long as the residents agree to it. So far 44 additional homes have agreed to let the EPA do more testing.
