Paperback. Etat : New. Print on Demand. This book details the results of a joint study by the United States Geological Survey and Minnesota State Board of Health regarding surface water quality in Minnesota. The study focused on the physical and chemical aspects of rivers, lakes, and streams in the state, with emphasis on potential hazards to public health. The author, an assistant hydrographer for the survey, and other specialists examined samples taken from multiple regions and water systems and carried out both field and laboratory tests. The collected data offers insights into the character of surface water, the sources and types of pollution in each sample's watershed, and the relationship between water quality and incidence of waterborne illnesses such as typhoid fever. The work contributed to ongoing efforts to protect public health and water resources in Minnesota and provided a better understanding of the factors affecting surface water quality at that time.
