Regulation of Perchlorate


Nevada is waiting for the results of the National Academy of Sciences review and is expected to adopt the drinking water standard set by U.S. EPA for perchlorate.

In the meantime, if the level of perchlorate exceeds 18 ppb - the "Action Level" set by the state - water system operators are required to notify local government agencies. The state also recommends that consumers be notified.

Nevada and local industries are continuing their longstanding cooperative efforts to identify sources of perchlorate around the state and clean them up as needed. Perchlorate is found primarily in water supplies for Las Vegas and southern portions of the state; Reno, Carson City and other northern cities are not affected.
