Drinking Water
“Our mission is to protect public health and the environment by providing oversight, guidance, and support, while fostering collaboration with safe drinking water partners.”
Safe drinking water is vital to the public health, welfare, and economy of Nevada. The moment a person opens a drinking water tap, it represents perhaps the most intimate connection between public trust and the government's duty to protect public health. Unlike many other day-to-day government activities, drinking water regulation has a direct and immediate effect on the well-being of every citizen.
The Federal Safe Drinking Water Act provides broad and consistent public health protection throughout the nation. It is the responsibility of owners, managers and operators of public water systems to meet the requirements of the Act. Our Bureau implements the requirements of this Act.

News and Program Updates
Interest in drinking water system compliance is high. The Bureau of Safe Drinking Water reviews compliance data from about 600 public water systems based on State and Federal regulations. If a water system’s data exceeds a maximum contaminant or action level, that system is non-compliant. Nevada currently has 22 systems that are non-compliant with health-based primary drinking water standards and 12 systems that are non-compliant with secondary drinking water standards. This report, Nevada Public Water Systems in Non-Compliance with Drinking Water Standards - PDF, is updated quarterly.
January 2025 - The fifth Unregulated Contaminant Monitoring Rule (UCMR 5), which began in 2023, continues through 2026, is looking at 29 PFAS compounds and lithium in drinking water. Sampling is being conducted at all large (serving > 10,000 people), medium (serving between 10,000 and 3,300 people) and, small (serving less than 3,300 people) public water systems (PWS) across the United States. The 7th set of analytical results, representing 66% of all data that will be collected, was released January 5th, 2025. There will be subsequent data releases every quarter through 2026. Staff will continue to communicate public notices and Consumer Confidence Report (CCR) requirements as results are released.For information on PFAS, including health effects, Nevada occurrence information, treatment, and funding opportunities visit the NDEP PFAS in Nevada webpage. For information on lithium, visit EPA’s UCMR 5 page.
April 2024 - EPA announced the final National Primary Drinking Water Regulation (NPDWR) for six PFAS on April 10, 2024. The EPA established legally enforceable levels, called Maximum Contaminant Levels (MCLs), for several contaminants with individual mixtures containing at least two or more contanminats. They used a Hazard Index to account for the combined and co-occurring levels of PFAS in drinking water. EPA finalized health-based, non-enforceable Maximum Contaminant Level Goals (MCLGs) for PFAS. More information on the final rule, along with associated timelines, can be found on the EPA PFAS web page
Information for Consumers
Information for Public Water Systems and Chemical Monitoring
Regulatory oversight for the Public Water System Supervision Program (PWSSP) is provided by the Nevada Division of Environmental Protection, Bureau of Safe Drinking Water, Southern Nevada Health District and Washoe County Health District. Staff monitor water sample analysis reports, performs sanitary surveys of public water systems, reviews and approves plans for water system projects, provides public water system training, maintains essential records, revises, adopts and enforces all regulations.
