Drinking Water

The Water Resources Department provides potable drinking water to residents, yet draws none of its freshwater supply from the ground directly below the city.

Keeping an Eye on Our Drinking Water

Unregulated Contaminant Monitoring
The Water Resources Department is participating in the U.S. Environmental Protection Agency’s (EPA) Fourth Unregulated Contaminant Monitoring Rule (UCMR4). This program helps the EPA measure the occurrence of specific contaminants in drinking water and determine if they need to be regulated in the future. Currently, no health-based standards have been established for these unregulated contaminants under the Safe Drinking Water Act (SDWA). More information on the UCMR4 program can be found at epa.gov/dwucmr.
