+Is West Valley City, UT tap water safe to drink in 2024?
Every one of the 76 contaminants measured in West Valley City, UT's 2024 Consumer Confidence Report is below its federal limit. "Safe" under the EPA's drinking-water standards is health-based, not aesthetic — but by those standards, no measured contaminant in this report exceeds its enforceable threshold. Individual health concerns (e.g. immunocompromised, infant, pregnancy) may warrant additional filtering regardless of compliance.
+What contaminants are in West Valley City, UT tap water?
76 contaminants were measured in West Valley City, UT's 2024 Consumer Confidence Report, spanning pfas ("forever chemicals"), metals, and disinfection byproducts. 11 have an enforceable federal limit; the rest are detected but unregulated. Every measured value, in the utility's own units, is on this page.
+Are any contaminants in West Valley City, UT tap water approaching the federal limit?
One contaminant is between 80% and 100% of the federal limit in this report: HAA5. Approaching means measured but not in violation — a margin that can close quickly if conditions change.
