Industrial Acid River Pollution

“Colonel Shunk, stationed at Pittsburgh, who has been investigating the extent and causes of Ohio River pollution, has submitted findings which show that the chief sources of the impurities which kill many fish annually and endanger the lives of persons who use the river water for drinking purposes are the mines and factories, particularly the former. It is estimated by the engineering authorities that 65 tons of pure acid are dumped into the Ohio River every day, 60 tons of which are in the water that flows from mines and the remaining 5 tons from mills and factories along the river.”
