What's in Pine Valley Mutual Wc — Pine Valley, Ca, CA tap water
2 contaminants in Pine Valley Mutual Wc — Pine Valley, Ca, CA's water sat at or above a federal limit, led by Nitrate at 2.4x the limit.
- !2 contaminants at or above a federal limit — worst is Nitrate at 2.4x
- !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.
- −54 contaminants at or above a federal limit
- −0 contaminants within 20% of a limit
- −0 open health-based violations
- −0 open monitoring / reporting violations
- −6 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.

Levels above the federal limit can cause 'blue baby syndrome,' a serious oxygen-transport condition in infants.
Higher than 95% of CA systems that report it · higher than 95% of U.S. systems
