What's in Lakeside Wd — Lakeside, Ca, CA tap water
1 contaminant in Lakeside Wd — Lakeside, Ca, CA's water sat at or above a federal limit, led by Arsenic at 5.4x the limit.
- !1 contaminant at or above a federal limit — worst is Arsenic at 5.4x
- !1 contaminant within 20% of a limit
- !10 of 27 core regulated contaminants reported — 17 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.
- −36 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
- −14 core regulated contaminants never reported (10/27)
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
- Arsenic5.4× the federal limit0–54.2 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
- Turbidity90% of the federal limit0.03–0.9 NTU · limit 1 NTU
High turbidity can shelter microbes from disinfection; the EPA enforces it through a treatment-technique standard.
Higher than 75% of CA systems that report it · higher than 80% of U.S. systems

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