Drinking Water Contaminant Candidate List - Draft; Notice of Availability

The San Diego State University Center for Tobacco and the Environment urges the EPA to include nicotine and cotinine in the national drinking-water monitoring framework.

Matanzas Riverkeeper, a non-profit environmental organization, supports the inclusion of PFAS and microplastics on the Draft Contaminant Candidate List 6. However, they argue that the EPA must move beyond mere recognition to establish enforceable national standards, source reduction requirements, and stronger protections against these contaminants.
