How to read the verdicts: Good means the measurement sits under half of the federal legal limit. Caution means it is legal but at or above half the limit, the range where health researchers advise staying lower. Too high means it exceeded the legal limit. Taste standards are EPA secondary limits for taste and appearance. Hardness uses the USGS scale, where anything over 180 mg/L counts as very hard. When a utility blends water from wells and imported supplies, the same chemical can appear twice with each source's result.
