People also ask about Salem, OR's water
+Is Salem, OR tap water safe to drink in 2023?
Every one of the 56 contaminants measured in Salem, OR's 2023 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.
