What the violations mean
Haloacetic Acids (HAA5)
16 incidentsHaloacetic acid byproducts exceeded the federal limit
Long-term exposure to HAAs may increase cancer risk
Total Trihalomethanes (TTHMs)
6 incidentsDisinfection byproduct levels exceeded the federal limit
Long-term TTHM exposure may increase bladder cancer risk
Long Term 2 Enhanced Surface Water Treatment Rule
5 incidentsThe system failed required surface water treatment or filtration standards
Untreated or inadequately treated surface water can contain bacteria and viruses
Groundwater Rule
3 incidentsThe system did not complete a treatment step or action that the Groundwater Rule requires (a treatment technique violation).
The utility had to notify customers about each of these violations.
Where the water comes from
Lumberton MDWCA draws water from 1 surface water intake and 1 infiltration gallery.
Annual water quality report
Lumberton MDWCA 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 Lumberton MDWCA for a copy.

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.
