What the violations mean
Haloacetic Acids (HAA5)
17 incidentsHaloacetic acid byproducts exceeded the federal limit
Long-term exposure to HAAs may increase cancer risk
Total Trihalomethanes (TTHMs)
13 incidentsDisinfection byproduct levels exceeded the federal limit
Long-term TTHM exposure may increase bladder cancer risk
Surface Water Treatment Rule
1 incidentThe system did not complete a treatment step or action that the Surface Water Treatment Rule requires (a treatment technique violation).
The utility had to notify customers about this violation.
Where the water comes from
Tupper Lake V draws water from 2 wells and 1 surface water intake.
Annual water quality report
Tupper Lake V 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.
Where the state allows it, systems serving fewer than 10,000 people may publish the report in a local newspaper or news site instead of mailing it, and must provide a copy on request.
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 York.
Certified drinking water labs by state EPA guidance for private wells
