Total Trihalomethanes (TTHMs)
35 incidentsDisinfection byproduct levels exceeded the federal limit
Long-term TTHM exposure may increase bladder cancer risk
Haloacetic Acids (HAA5)
32 incidentsHaloacetic acid byproducts exceeded the federal limit
Long-term exposure to HAAs may increase cancer risk
Where the water comes from
Miami Water Users Association draws water from 1 surface water intake.
Annual water quality report
Miami Water Users Association 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 500 or fewer people may meet the rule by telling customers the report is available on request, so you may need to ask Miami Water Users Association for a copy.
Find a posted report with EPA's Consumer Confidence Report search
Testing your own water
To test the water at your tap, or a private well this record does not cover, use a laboratory certified for drinking water by New Mexico.
