Selbyville Water Department Has Levels of Total Trihalomethanes (TTHM) Above Drinking Water Standards

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

The Division of Public Health routinely monitors for the presence of drinking water contaminants. Testing results from 2019 to 2021 show that our system exceeded the standard, or maximum contaminant level (MCL), for TTHM, a disinfection by-product (DBP). The standard for the disinfection by-product, TTHM, is 80 parts per billion (ppb). It is determined by a four-quarter running annual average. The most recent four-quarter running annual average at our system was 83 ppb.

What should I do?

  • There is nothing you need to do. You do not need to boil your water or take other corrective actions. However, if you have specific health concerns, consult your doctor.
  • 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. TTHMs 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 happened? What is being done?

When disinfectants are used in the treatment of drinking water, disinfectants react with naturally-occurring organic and inorganic matter present in water to form DBPs. We are working on flushing the system to remove the TTHMs.
