Under the federal New Deal in the late 1930s, the Works Project Administration authorized a series of surveys of major watersheds to gauge water quality and sources of pollution. In Massachusetts, the studies were coordinated by the Massachusetts Department of Health and resulted in a series of more or less detailed reports issued between September 1936 and January 1938.
The pollution survey collection contains reports for six major watersheds in New England — the Blackstone, Hoosic, Housatonic, Merrimack, Nashua, and Ten Mile — measuring the impact of both civic and industrial waste on regional water resources.
