ABOUT WATER QUALITY IN NEVADA

Nevada water quality varies significantly by city and water system. The EPA's UCMR5 monitoring program tested all systems serving 3,300+ people for 29 PFAS compounds between 2023 and 2025. In Nevada, 3 of the 3 tracked cities returned results with active MCL violations — meaning detected PFAS levels exceed the EPA's legally enforceable maximum.
