The Water Quality Information Service is a resource for researchers, agency officials, and the general public for organizing and presenting historic water quality data from the St. Joseph River and its tributaries. The WQIS is maintained by the St. Joseph River Watershed Initiative in collaboration with the ERC hosting it at IPFW.
The URL is wqis.ipfw.edu.
Pick your location, pollutant and time frame and see what you get as a graph or as a table. The service is limited by the data available for it. We hope in the future to add: sites, data sets and new features!!
The WQIS is free, but registration is required so that we can learn who is using it.
