The surface water and groundwater quality in the study area of the Portage Creek watershed was analyzed to determine the possible effects of urbanization. Dry weather and wet weather surface water and groundwater samples were collected from June 1986 to November 1986 at selected stations in the watershed.

Water samples were analyzed for 26 inorganic and organic parameters. Most concentrations were below analytic method detection limits. The analytical data indicate that sodium and chloride are the principal contaminants resulting from urbanization. The probable source of the contamination is deicing salt applied to the City of Portage, Michigan streets.

Overall, the surface water and groundwater quality in the study area was good during dry weather sampling events for the selected parameters. Wet weather sampling event results revealed temporary quality degradation to the creek from urban runoff via the Portage Consolidated Drain No. 1.
