What's in Elsinore Valley MWD — Lake Elsinore, Ca, CA tap water
5 contaminants in Elsinore Valley MWD — Lake Elsinore, Ca, CA's water sat at or above a federal limit, led by Turbidity at 2.5x the limit.
- !5 contaminants at or above a federal limit — worst is Turbidity at 2.5x
- !1 contaminant within 20% of a limit
- !15 of 27 core regulated contaminants reported — 12 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
- −6 core regulated contaminants never reported (15/27)
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
- Turbidity2.5× the federal limit0–2.5 NTU · limit 1 NTU
High turbidity can shelter microbes from disinfection; the EPA enforces it through a treatment-technique standard.
Higher than 90% of CA systems that report it · higher than 90% of U.S. systems
- PFOA2.1× the federal limit0–8.4 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 75% of CA systems that report it · higher than 85% 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
- PFOS1.1× the federal limit0–4.3 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 45% of CA systems that report it · higher than 55% of U.S. systems
- Gross Alpha1.0× the federal limit11.6–15.5 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
- Arsenic91% of the federal limit0–9.1 ug/L · limit 10 ug/L
A known human carcinogen; long-term exposure is linked to skin, bladder, and lung cancer.
Higher than 95% of CA systems that report it · higher than 95% of U.S. systems

What this report doesn't tell you
12 of the 27 contaminants a community water system normally reports do not appear anywhere in Elsinore Valley MWD — Lake Elsinore, Ca, CA's data. Absent is not the same as absent-from-the-water — it means nobody published a number.
