Total Trihalomethanes (TTHM) Maximum Contaminant Level (MCL) Violation



Our water system violated a drinking water standard for Trihalomethanes. Although this incident was not an emergency to our customers, you have the right to know what happened and what we are doing to correct this situation.

Pembroke Pines routinely monitors for drinking water contaminants. Total Trihalomethanes (TTHMs) are by-products of the reaction of the chlorine disinfectant with the natural organic and inorganic matter in the water. The state of Florida as well as many other states requires the use of a disinfectant to minimize the possibility of bacterial contamination in the drinking water distribution system. The Maximum Contaminant Level (MCL) set by the US Environmental Protection Agency (EPA) for TTHMs is 80 parts per billion (ppb). The last test results for the sample collected on June 23, 2017 was 53.8 ppb for TTHM. Based on test results for samples collected in previous three calendar quarters and 2nd quarter’s sample collected in June, the locational running annual average (LRAA) for TTHMs is 89.4 ppb as shown in the table below. Based on the LRAAs for TTHM, a MCL violation exists.

What should I do?
You do not need to boil your water or take any corrective actions. However, 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, you would have been notified immediately.

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 corrective action is being taken?
The City has installed a re-carbonation system at the water treatment plant to help with enhanced softening and the removal of disinfection by-product precursors The City has also optimized chemical feed rates for the system with increased monitoring to ensure chlorine dosages are at the minimum necessary.

Pembroke Pines will continue to issue public notices to you on a quarterly basis as long as the locational running annual average exceeds the MCL, as required by FDEP. If you should have any questions concerning this situation, please do not hesitate to contact Customer Service Hotline at 954-518-9090.

Please share this information with 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.

This notice is being sent to you by the City of Pembroke Pines.
