Michigan's E.coli Pollution and Solution Mapper

This interactive map supports Michigan’s Statewide E. coli TMDL (Total Maximum Daily Load) by helping users explore potential sources of fecal contamination in rivers, lakes, and beaches. Developed by EGLE, the tool allows communities to evaluate both point and nonpoint pollution sources locally, while emphasizing that identified sources may not impact every water body. The map is a resource for understanding the complexity of E. coli pollution and guiding efforts to reduce contamination across the state.
