Cities ranked by the records
Ranked by the Purity Score of each city's main water system, highest first. Scores belong to water systems; there is no county score. The score is computed only from contaminants measured in the published EPA record, so this ranks the record, not which city's water is safest. How the score works.
0of 1 city above the 15 µg/L action level
Based on each system's 90th-percentile result. Lead from household plumbing isn't in this record.

Frequently asked
How does Polk County tap water compare across cities?
PurityMap ranks 1 city in Polk County by the Purity Score of each city's main water system, computed only from contaminants measured in the published EPA record. Scores belong to water systems, not to cities. The highest published score is Livingston's main water system: CITY OF LIVINGSTON · PWSID TX1870002 · Purity Score 61 (Fair) · Confidence: moderate · Assessed at the water-system level. The ranking compares the records, not which city's water is safest, and your own tap can differ with household plumbing.
How many Polk County cities had a PFAS sample above a 2024 EPA limit?
1 of 1 Polk County city report had a PFAS sample above a 2024 EPA limit in EPA's UCMR 5 testing, including Livingston (PFOS 6.9 ng/L). That limit is judged on a yearly average, and water systems have until 2029 to meet it, so a single sample is not a violation. PFAS were detected at any level in 1.
Is there lead in Polk County tap water?
Utilities report lead as a 90th-percentile result from home taps. 1 of 1 Polk County cities reported a value above zero, and none was above the 15 µg/L federal action level. Lead usually comes from a building's own pipes and fixtures, so only a test at your tap tells you what you drink.
