From this story in the Pittsburg Post-Gazette:
Spring water, cold as winter and clear as a windowpane, gushes out of mossy ground in a clearing sprinkled with blooms of forget-me-not next to Stone Camp, the home of the Sykesville Hunting Club in the Moshannon State Forest. The bubbling flow has attracted generations of folks from Clearfield County and beyond, but staked into the ground now is a homemade sign bearing the warning: "Contaminated Water." The sign seems out of place. Larry Righi certainly thinks so, even though he had a hand in putting it up months after a torn liner under one or more EOG Resources Marcellus Shale drill cuttings pits allowed leakage that contaminated groundwater feeding the spring almost two years ago.
