NORRISTOWN, Pa. (CBS) — Pennsylvania lawmakers are asking the U.S. Navy to fund a study to evaluate potential health risks from chemicals found in wells and drinking water around the former naval bases in Warminster, Bucks County and Horsham, Montgomery County.

State Reps Bernie O’Neill and Todd Stephens are requesting the Navy fund an independent assessment of whether or not there are health risks stemming from past water contamination in Horsham and Warminster.

Stephens says the water is currently safe to drink as the contaminated wells are no longer used. But, he adds, they need to know if there are increased health risks from PFOAs and PFOSs that were in the water supply. And, if so, are there steps that need to be taken now.

The chemicals were in foam used by firefighters on the bases, and Stephens isn’t blaming the Navy for the contamination. He says they’ve been a great partner, both when the base was active and through the transition.
