This article discusses a contamination incident in March 1964 by a paper mill situated on Lake Erie 2 miles east of the Chestnut St. filtration plant. It was found that the addition of potassium permanganate in dosages of 1.5‐2 ppm, combined with a pH of 8.3, reduced tannin‐lignin concentrations from 0.8‐1.6 ppm in the raw water to 0.1‐0.5 ppm in the finished water. Also, construction has begun on a revolutionary deep‐well disposal system that will pump all of the offending effluent underground by the end of 1965.
