Ken Dufalla collects a water sample while monitoring bromide levels at Clyde Mine discharge along Ten Mile Creek in Greene County. In fresh water, elevated levels of bromide, a substance usually found in seawater, are always a result of human activity. Dufalla is president of the Harry Enstrom Chapter of Izaak Walton League in Greene County and a long time advocate for clean water. As of March 2012, high bromide concentrations- some contend as a result of Marcellus Shale activity- remained a concern in many of the region's rivers. © Martha Rial/MSDP 2012
