SHEFFIELD, Pa. — Bill Eckert slipped into his hip waders and splashed through the small stream near his cabin in the Allegheny National Forest.
He didn’t bring his fishing pole this time. Instead, Eckert bent down and let the cold water fill the assorted bottles he carried.
Eckert was among a few dozen volunteers collecting water samples that could help researchers develop a clearer picture of water quality in Pennsylvania.
