3 contaminants in City of Menifee, CA's water sat at or above a federal limit, led by Turbidity at 97.0x the limit.
- !3 contaminants at or above a federal limit — worst is Turbidity at 97.0x
- !1 contaminant within 20% of a limit
- !14 of 27 core regulated contaminants reported — 13 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
- −4 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
- −8 core regulated contaminants never reported (14/27)
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.
Full grading methodology, constant for constant →What to worry about
- Turbidity97.0× the federal limit97 NTU · limit 1 NTU
High turbidity can shelter microbes from disinfection; the EPA enforces it through a treatment-technique standard.
Higher than 95% of CA systems that report it · higher than 95% of U.S. systems
- Bromate1.9× the federal limit0–19 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
- Chlorine Total1.1× the federal limit0–4.3 mg/L · limit 4 mg/L
Higher than 95% of CA systems that report it · higher than 95% of U.S. systems
- TTHM88% of the federal limit9.1–70 ug/L · limit 80 ug/L
Long-term exposure above the federal limit is linked to liver, kidney, and central-nervous-system effects and increased cancer risk.
Higher than 95% of CA systems that report it · higher than 90% of U.S. systems
