What's in Templeton Csd — Templeton, Ca, CA tap water
2 contaminants in Templeton Csd — Templeton, Ca, CA's water sat at or above a federal limit, led by Nitrate at 1.7x the limit.
- !2 contaminants at or above a federal limit — worst is Nitrate at 1.7x
- !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.
- −42 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
- −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.

- Nitrate1.7× the federal limit0–17.1 mg/L · limit 10 mg/L
Levels above the federal limit can cause 'blue baby syndrome,' a serious oxygen-transport condition in infants.

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