What's in Home Gardens County Wd — Corona, Ca, CA tap water
5 contaminants in Home Gardens County Wd — Corona, Ca, CA's water sat at or above a federal limit, led by PFOA at 60.0x the limit.
- !5 contaminants at or above a federal limit — worst is PFOA at 60.0x
- !16 of 27 core regulated contaminants reported — 11 never appear in this report
- ✓No open federal violations
+How this score is calculated
Every system starts at 100. Points come off for measured levels, for the federal violation record, and for how much of the core regulated set the utility actually reported. All three inputs are the utility's own published numbers and EPA's own records.
- −60 contaminants at or above a federal limit
- −0 contaminants within 20% of a limit
- −0 open health-based violations
- −0 open monitoring / reporting violations
- −0 health-based violations resolved in the last 5 years
- −5 core regulated contaminants never reported (16/27)
A 90–100 · B 80–89 · C 70–79 · D 60–69 · F below 60. A system reporting under a third of the core set is capped at C however clean its numbers look — a short report is not a clean bill of health.

- PFOA60.0× the federal limit0–240 ng/L · limit 4 ng/L
Linked to cancer, liver damage, and immune effects; the EPA set an enforceable limit of 4 parts per trillion.
Higher than 95% of CA systems that report it · higher than 95% of U.S. systems
- PFOS60.0× the federal limit0–240 ng/L · limit 4 ng/L
Linked to cancer, thyroid disease, and immune effects; the EPA set an enforceable limit of 4 parts per trillion.
Higher than 95% of CA systems that report it · higher than 95% of U.S. systems
- Perfluorohexanesulfonic acid5.8× the federal limit0–58 ng/L · limit 10 ng/L
Regulated by the EPA at 10 parts per trillion and included in the PFAS Hazard Index.
Higher than 90% of CA systems that report it · higher than 95% of U.S. systems
- Bromate2.0× the federal limit0–20 ug/L · limit 10 ug/L
Classified as a probable human carcinogen; the EPA sets a strict maximum contaminant level.
Higher than 95% of CA systems that report it · higher than 95% of U.S. systems
- Gross Alpha1.0× the federal limit0–15 pCi/L · limit 15 pCi/L
Long-term exposure above the federal limit increases cancer risk.
Higher than 95% of CA systems that report it · higher than 95% of U.S. systems
