The Montana State Board of Health was established in 1901. The Division of Water and Sewage was created in 1911. Its first director was W. M. Cobleigh. From the organization of the division until 1923, bacteriological and chemical examinations of water samples were carried on at the State Agricultural College in Bozeman. On July 1, 1923, the office and laboratory were moved to Helena and H. B. Foote became the division director. W. M. Cobleigh continued as a consultant. In the early years, work centered around installation of sewage treating plants to prevent pollution of streams, protect watersheds, and provide clean drinking water; creation of regulations governing preparation and submission of designs for sewer systems and treatment plants; and analyzing public and private water supplies. The division also analyzed water from swimming pools and reviewed heating, lighting, ventilating, and plumbing plans for new school buildings to insure a safe environment.
On April 15, 1944, the division was renamed the Division of Sanitary Engineering because of the expansion of field work and the development of sanitary engineering as a more clearly-defined field. By 1944 the division was conducting field inspections of sewage disposal systems, stream pollution problems, and public swimming pools. The division also reviewed plans for public water supplies, public sewage and industrial waste disposal systems, and public swimming pools. Included in the studies of stream pollution problems was the mine and smelter wastes in the upper reaches of the Clark Fork River. In May, 1950, the State Board of Health and the State Board of Examiners reached a general agreement on the subject of adequate salaries for staff members of the State Board of Health. This general agreement served as the basis for initiating a department-wide reorganization.
As part of that reorganization, the Division of Sanitary Engineering and the Division of Food and Drug were combined to create a new Division of Environmental Sanitation. C. W. Brinck was appointed director of the new division on May 1, 1951. The division was divided into three sections: water, sewage, and general sanitation. The Water Section was in charge of water supplies--both public and private--swimming pools, well drilling for public water supplies, and review of plans for water works, swimming pools, school buildings, and other public buildings. The Sewage Section was in charge of sewage disposal, stream pollution abatement, plan review, sewage plant systems, cesspool and septic tank cleaning, and garbage disposal. The General Sanitation Section was itself divided into two areas run by the sanitarian and by the chemist. Sanitary inspection services included inspections of restaurants, meat markets, food manufacturing, soft drink/ ice cream parlors, tourist camps, locker plants, camp sanitation, and mattress factories. In addition, the sanitarian was responsible for insect and rodent control. The chemist was in charge of the laboratory, which conducted analyzes of water, sewage, soft drinks, meats, bakery products, canned goods, fruits for spray residue, insecticides and other poisons, drugs, and liquors.
In 1967 the Legislative Assembly created the State Department of Health. The State Board of Health continued in an advisory capacity, but the day-to-day administration of the state laws regarded public health and related matters were relegated to the new department. The State Board of Health became The Department of Health and Environmental Sciences in 1971 with the passage of Governor Anderson’s Executive Reorganization Order 9-71. In 1991, though it remained a part of the Department of Health and Environmental Sciences, the role of the Environmental Sciences Division was considerably expanded to include: Natural Resource Damage Assessment, a Petroleum Tank Release Compensation Board, a Superfund Section, and an Underground Storage Tanks Section.
The Environmental Sciences Division eventually became its own separate department, renamed the Department of Environmental Quality, in 1995, comprised of the following divisions: Director’s Office, Air Quality, Centralized Services, Energy, Environmental Remediation, Reclamation, Waste Management, and Water Quality.
This collection consists of two subgroups: General files from the Environmental Science Division and Tom Ellerhoff’s files from the division.
The general Environmental Science Division files consist of eight series: Correspondence, Court Papers, Financial Records, Hearings, Laboratory Records, Organizational Records, Reports, and Subject Files, and Miscellany. Subject matter includes soil and water testing for arsenic, bacillus coli, and cyanide, industrial use of water, community sanitation, water maintenance schools, legislation, and the Dean William Cobleigh Memorial Scholarship. More specifically, the Laboratory Records include water quality basic data reports for the Yellowstone River. Also of interest are the Subject Files (1918-1969), which contain information on the American Smelting and Refining Company plant at East Helena; Austin's Packing Company in Glasgow; the Big Sky Development Corporation's wood fiber plant/pulp mill on the Flathead River near Kalispell; Libby Dam; privies, including State Board of Health circular 13 on building a sanitary pit privy; tularaemia, and the Waldorf Paper Products Company pulp mill near Missoula.
Tom Ellerhoff’s files consist of four series: Church Universal and Triumphant (CUT), Lasting Legacy: Montana’s Environmental Health Pioneers (LL), Subject Files, and Press Clippings. CUT and LL primarily consist of reference material, drafts, and correspondence for the writings of Tom Ellerhoff on those subjects. Subject Files include the 1989 Helena Train Derailment, Bonneville Power Administration (BPA), the Internal Organ Newsletter, and Transisco Rail.
