Water Source & Treatment
Where this water originates and how it's treated before reaching your tap.
Source: Tahoe City Public Utility District Consumer Confidence Report.
ZipCheckup is not affiliated with this water utility. Treatment and source data are sourced from the utility's published CCR filings.
Drinking water sources include wells and springs deep within the earth, providing clean, high quality water that consistently meets all standards without significant treatment. Quail Lake/McKinney Shores uses both a treated surface water source and a groundwater source. A Source Water Assessment for each active source was completed in January, March, and May of 2003. The sources are most vulnerable to sewer collection systems, surface water, above ground storage tanks, transportation corridors, historic gas stations, and water supply wells.

Federal UCMR5 PFAS Monitoring: Tested Clean
This water system was tested under the federal EPA Unregulated Contaminant Monitoring Rule (UCMR5). No PFAS compounds were detected.
Current MCL reflects the lowest state-enforceable limit (NYS 10 ppt for PFOA/PFOS, effective August 2020). The federal final MCL of 4 ppt for PFOA/PFOS (EPA April 2024 rule) is not enforceable until April 2029. Detections above 4 ppt but below 10 ppt are below current MCL but above the future federal limit.
