Journal of the Minnesota Academy of Science

Representative factors influencing water quality in the Albert Lea, Minnesota area were chosen as to assess water quality and changes in the watershed which has been described as an earlier valley of the Shell Rock River.

Parameters representative of chemical, bacterial, and thermal pollution were, respectively, total phosphorous, total and fecal coliform counts, and temperature. Statistical analysis has revealed that significant differences in some parameters measured do exist when various sampling stations of a given sampling date are compared. Statistical analysis also has indicated that correlations do exist between fluctuation patterns when all sampling stations of a given sampling date …
