I came across this fascinating collection of pictures of the Lewiston/Auburn Maine area going all the way to the source of the Androscoggin river in New Hampshire. The pictures were taken by Charles Steinhacker for the EPA. At this time, 1973, the struggle was on to clean up the river, which had endured almost a century of industrial and municipal waste. The pulp mills deposited all their waste directly into the river. The towns along the shore did the same. The smell of the river was legendary.
At this time the Clean Water Act had just been passed with high hopes. It would take many years, but the river would eventually be restored. I was a student at Lewiston High School at the and remember the time and the issues well.
