Toledo's 2014 water crisis, when microcystin from harmful algal blooms rendered tap water unsafe for 500,000 people, became a watershed moment for Great Lakes water quality. The city has since invested over $500 million in treatment upgrades, including advanced oxidation and activated carbon. Agricultural runoff from the Maumee River watershed continues to fuel algal blooms.
