Abstract

Bacteriological quality of water along commonly used canoe routes in the Boundary Waters Canoe Area along the Minnesota-Canadian border was checked by estimating the most probable number (MPN) of coliforms and total plate counts of samples collected over a wide geographic area. Results show that much of the water used for drinking purposes does not meet United States Public Health Service standards for potability. Additional study is needed to determine (1) whether USPHS standards have any validity as applied to wilderness waters where high counts probably do not indicate human fecal contamination and (2) whether animals contributing to high counts of coliforms are or might become carriers of water borne organisms pathogenic for man.
