About 75 residents protested on Thursday in Butler, Pa., after an energy company said it would no longer provide replacement water to some residents.
The residents of The Woodslands, a rural community in southern Butler County about 30 miles north of Pittsburgh, picketed outside the offices of Rex Energy Inc.
The company, based in State College, Pa., had provided about a dozen families with 800-gallon plastic tanks and filled them regularly for a year.
But the company drained and removed the tanks, citing a series of test results that fail to establish a link between drilling and water problems in Connoquenessing Township.
The state Department of Environmental Protection began tests in early 2011, but couldn't link contamination to the Rex drilling, officials said.
A grass-roots group, Marcellus Outreach Butler, wants the tests redone. That group and Protecting Our Waters, a Philadelphia-based eco-group, want the U.S. Environmental Protection Agency to intervene and to provide drinking water.
Residents say their water problems began after the drilling got under way.
