"CAMBRIA COUNTY, Pa. -- A pipe is spewing toxic water into Topper Run from the old Maryland No. 1 coal mine here."

"Take a deep breath, and gag on the stench of rotten eggs.

The mine has been belching acid water since it was abandoned in the 1960s. No fish swim where this water flows, and iron in discharges has stained the streambed orange, while aluminum has tinted rocks white.

Several dirty discharges are contributing to the degradation of the Little Conemaugh River Watershed, one of the most polluted in Pennsylvania. The contamination is evident where the discolored Little Conemaugh joins clear-running Stonycreek in Johnstown."
