Match the public water system name and identifier to the supplier on your water bill before using EPA UCMR 5 results. Review the sampling location, date, units and reporting level. A city name alone does not establish which system serves an address, and an individual survey result does not establish regulatory compliance.
Check your water bill for your utility name and confirm the reporting year. See EPA’s guide to finding your annual water quality report.
