What the violations mean
Total Trihalomethanes (TTHMs)
2 incidentsDisinfection byproduct levels exceeded the federal limit
Long-term TTHM exposure may increase bladder cancer risk
Interim Enhanced Surface Water Treatment Rule
2 incidentsThe system did not meet a filtration or treatment requirement for surface water

Where the water comes from
Loring Development Authority draws water from 1 surface water intake.
Annual water quality report
Loring Development Authority 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 Loring Development Authority for a copy.
