Has Levels of Total Trihalomethanes (TTHMs) Above Drinking Water Standards

Our water system recently violated drinking water standards. Although this is not an emergency, as our customers, you have a right to know what happened, what you should do, and what we are doing to
correct this situation. Please share this information with all other people who drink this water, especially those who may not have received this notice directly (for example, people in apartments,
nursing homes, schools and businesses). You can do this by posting this notice in a public place or distributing copies by hand or mail.

We routinely monitor for the presence of drinking water contaminants. Results from the testing we conducted on 10/24/2023 for the quarter of October, November and December 2023 show that our
system exceeds the standard, or maximum contaminant level (MCL) for total trihalomethanes (TTHMs). The standard for TTHMs is 0.080 mg/L. City of Ellendale has a locational running annual average (LRAA) of 0.113 mg/L at site STG2-03.

What should I do?

  • You do not need to use an alternative (e.g. bottled) water supply. However, if you have
    specific health concerns, please consult your doctor.

What does this mean?

  • Some people who drink water containing Trihalomethanes in excess of the MCL over many years
    may experience problems with their liver, kidneys, or central nervous system, and may have an
    increased risk of getting cancer.

What happened? What is being done?

  • The annual TTHMs sample was taken which resulted in a sample that exceeded the maximum
    level. ND Department of Environmental Quality is requiring the city to sample quarterly for the
    next year, a public notice will be repeated if condition persists. The Public Works Crew has
    done flushing of mains to circulate the water system. We anticipate resolving the problem by
    the next sample date done in the first quarter of 2024.
