Abstract

Fecal coliform and Escherichia coli (E. coli) concentrations were determined in the St. Croix National Scenic Riverway to assess whether pathogenic organisms pose a potential problem for recreational use. Samples were collected from May through September 1999 at 22 locations on the St. Croix and Namekagon Rivers. No concentrations exceeded water-quality criteria or standards set by the U.S. Environmental Protection Agency or the states of Minnesota and Wisconsin. Maximum fecal coliform and E. coli concentrations were measured in the St. Croix River at St. Croix Falls, Wisconsin. Median fecal coliform and E. coli concentrations were greater in the St. Croix River near Woodland Corner, Wisconsin, and at Marine on St. Croix, Minnesota than at other locations sampled.There were no consistent short-term variations in fecal coliform or E. coli concentrations during the summer period or any significant relations between concentrations and stream discharge, based on these results.
