SCOPE AND CONTENTS OF THE RECORDS

Typed, near-print, and printed reports of stream pollution investigations, sewage field investigations, and studies of the quality of river water, prepared by the Environmental Sanitation Division and the Water Pollution Control Section of the Minnesota Department of Health until about mid-1967, and thereafter by the Water Quality Division of the Pollution Control Agency. Many of the reports contain photographs documenting the studies.

Also included are a report on sewage problems in Albany Village (1956) and at the American Crystal Sugar Company refinery in Moorhead, Minnesota (1951).

Accession Information: Accession number(s): 978-87; 986-111

Processing Information: Appraisal statement: Most of these reports were microfilmed by the agency. The originals

were transferred to State Archives due to poor legibility of many original pages, the presence of photographs, and subsequent interfilings or replacements with better-quality copies. Primary value to both agency and other users is informational, providing data on water quality for future consultation or comparison.

Retention and disposition: Retained in agency until microfilmed. Microfilm copy retained permanently in agency (#84-436, items 26, 27)
