Abstract |
The report is based on data available as of January 1, 1953, on sources of pollution and treatment facilities employed, and on stream conditions revealed by field surveys made by the Minnesota Department of Health over a period extending from 1939 through 1952. The report also presents information concerning use of water resources, pollution entering water resources and resulting damages, and benefits which may result from pollution prevention and abatement. The report has been limited to known sources of pollution and their effects upon adjacent streams. (Author Modified Abstract) |
