Sinkhole called threat to water supply in township, Penn State

STATE COLLEGE, Pa. -- An expanding sinkhole near Houserville may threaten an underground water source that supplies residents of College Township and Penn State, officials said.

Geology professor Richard Parizek said the hole started in mid-October on a bank of Slab Cabin Run under the Mount Nittany Expressway overpass. There are four wells downstream, three serving the University Park campus and the fourth making up half of the College Township Water Authority supply.

Parizek said the hole, expanded in recent weeks by heavy rains, could offer a conduit to the underground water reserves that supply all of the wells. If surface water from the creek reaches the purer groundwater, state health rules may force closure of the wells, officials said.

Township Manager Adam Brumbaugh termed the problem a significant one, and he said the water authority is closely monitoring its nearby well. Penn State is running similar evaluations at its three wells, he said.

Brumbaugh said the township water authority could draw on its other well to fulfill water needs. Past accounts indicate University Park could depend entirely on wells in the Big Hollow area if the Houserville-area source were shut down.

The state Department of Transportation has hired the State College firm HRI Inc. to correct the situation and will pay the cost of almost $86,000, officials said.
