Welcome to the Office of Drinking Water

The mission of the Office of Drinking Water is to protect the health of Delawareans by assuring safe drinking water through comprehensive monitoring, technical assistance and public education.

Delaware PFOA and PFOS MCL Development

The Division of Public Health in coordination with DNREC is in the process of developing a Delaware-specific MCL (Maximum Contaminant Level) for PFAS (Per- and polyfluoroalkyl substances) in drinking water. As such, an MCL implementation plan has been developed.
