This Day in History: 1911-12-13

Water pollution group meets this day in 1911 at Johns Hopkins University. The National Association for Preventing the Pollution of Rivers and Waterways was led by Charles E. Winslow of Yale University. The group’s main object was to push for legislation compelling all towns and cities to purify sewage before dumping it in the rivers. The group also called for a federal board “to assist in adjusting interstate sanitary matters.” (Dec. 7, 1911, Washington Post.)
