What should I do?

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

What does this mean?

• The levels detected do not pose an immediate risk to your health. 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 is being done?

We are investigating and taking the following necessary steps:

• The city currently monitors for TTHM’s in four different sites through our water system. Only one of the four was over the .080 threshold so far in 2022. The City is working closely with the EPA to keep bringing these levels down and correct the problem as soon as possible.
