Noah Donovan of Ellwood City examines a tray of leaf pack material he took from the stream at Jennings Environmental Education Center in Brady Township as part of the July 24 Wonderful World of Water day camp sponsored by Pennsylvania-American Water Co. The company, in partnership with the Pennsylvania Resources Council, used the day to teach children about water and the environment. Noah was looking for macroinvertebrate life, which usually means a healthy water source.
