+Is Pico Wd — Pico Rivera, Ca, CA tap water safe to drink in 2020?
The 2020 Consumer Confidence Report for the Pico Wd — Pico Rivera, Ca, CA water utility lists 2 contaminants at or above the federal limit: PFOS and PFOA. Whether that means the water is "unsafe" depends on which contaminant, how long the exposure, and individual health factors. The table on this page shows the measured value, the federal threshold, and the regulated statistic used for compliance.
+What contaminants are in Pico Wd — Pico Rivera, Ca, CA tap water?
20 contaminants were measured in Pico Wd — Pico Rivera, Ca, CA's 2020 Consumer Confidence Report, spanning metals, pfas ("forever chemicals"), and radionuclides. 12 have an enforceable federal limit; the rest are detected but unregulated. Every measured value, in the utility's own units, is on this page.
+Which contaminants exceed federal limits in Pico Wd — Pico Rivera, Ca, CA tap water?
2 contaminants in Pico Wd — Pico Rivera, Ca, CA's 2020 report sit at or above the federal limit: PFOS (6.1× the limit); PFOA (3.1× the limit). The EPA enforces these limits against the regulated reporting statistic — typically a running annual average or 90th percentile — not a one-off sample spike.
