In 1974, amid growing concern about pollution in the Great Lakes, researchers at Heidelberg College in Tiffin, Ohio, began tracking the stream chemistry of the state's rivers. Their work quantified watershed pollutants from sources such as sewage plants and rural runoff, and it led to efforts to stem the flow of agricultural phosphorus into Lake Erie. At this new site, project leader David Baker, now a professor emeritus, and colleagues share their wealth of data on 11 rivers for scientists to use in courses or research. Visitors can download Excel files for more than 88,000 water samples tested for phosphorus, nitrates, suspended solids, and other components. Tutorials put the information in context, and templates help users analyze the data.
