Where the water comes from
Union PWS draws water from 7 wells (1 of them for emergency, seasonal or other part-time use).
Annual water quality report
Union PWS must give its customers an annual water quality report (Consumer Confidence Report) by July 1, with the levels its tests found in the previous year.
Systems serving 10,000 or more people must mail or deliver the report to every customer, and from 2027 they must send it twice a year.
