IMPORTANT INFORMATION ABOUT YOUR DRINKING WATER Total

Trihalomethanes (TTHM) MCL Violation at Cibola Mutual Water Company

Our water system recently violated a drinking water standard. Although this incident was not an emergency, as our customers, you have a right to know what happened and what we did (are doing) to correct this situation.

We routinely monitor for the presence of drinking water contaminants. Testing results from April 2018- January 2019 show that our system exceeds the standard, or maximum contaminant level (MCL), for TTHM. The standard for TTHM is 0.080 mg/L. It is determined by averaging all the samples collected at each sampling location for the past 12 months. The level of TTHM averaged at one of our system's locations for April 2018- January 2019 was 0.087 mg/L.

What should I do?

There is nothing you need to do. You do not need to boil your water or take other corrective actions. If a situation arises where the water is no longer safe to drink, you will be notified within 24 hours.

If you have a severely compromised immune system, have an infant, are pregnant, or are elderly, you may be at increased risk and should seek advice from your health care providers about drinking this water.

What does this mean?

This is not an emergency. If it had been an emergency, you would have been notified within 24 hours. TTHM are four volatile organic chemicals which form when disinfectants react with natural organic matter in the water.

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 have lowered the amount of water in the storage tank to two days of storage, so water is fresher when entering the distribution system. Applying for a grant to install equipment to lower TTHM's. We anticipate resolving the problem within the next 12 months.
