Flint, Michigan
Now synonymous with lead poisoning, the city of Flint is still recovering from a policy change that resulted in massive lead contamination of municipal tap water. Although lead levels have dropped to about 12 parts per billion—below the federal limit of 15 parts per billion—city officials say individual homes may still experience contamination from the lead pipes found throughout the city. Though lead levels in the water have improved, because medical professionals have not identified a safe blood lead level in children, many parents and community members in Flint are hesitant or unwilling to serve tap water to children. State and federal programs have promised to replace more than 18,000 lead-contaminated service lines across the city; as of December 2017, some 6,000 pipes had been replaced, but work is moving slowly and the project is not expected to be completed until 2020.

The waste generated by this industry has led to dangerous contamination in the waterways and wells on which many Native Americans rely for drinking water. Obtaining federal assistance to clean up the water is a formidable challenge, so some grassroots organizations are addressing the issue directly: The Navajo Water Utility Authority and the nonprofit DigDeep are working hard to provide clean water to Navajo families.
