Water Advisory Letter Facts

Water Facts

Recently, the City of Troy (and many other Texas cities and water companies) was (were) required by TCEQ to send letters to all water customers about the level of Trihalomethanes that were detected in our water system in January of 2016.

As the letter indicated and the TCEQ website states, you do not need to seek an alternative water supply, nor do you have to stop buying fountain drinks or making ice. 

Additionally, the TCEQ website and the letter state:

Notification is not intended to suggest that you or your family members will be harmed by the detected levels, but instead is meant to keep you informed

The mandatory wording in the letter that has caused concern and been misinterpreted by the media  is the section that states that some people who drink water containing trihalomethanes in excess of the MCL over many years may experience serious health issues.

TCEQ's website advises that : When the EPA establishes the MCL for a chemical that is known or suspected to cause adverse health effects from long-term exposures, it assumes that the people who drink that water consume about half a gallon of it every day for seventy years (approximately one lifetime). 

What are Trihalomethanes? 
Trihalomethanes (THMs) are a group of volatile organic compounds that are formed when chlorine, which is added to the water during the treatment process for disinfection, reacts with naturally-occurring organic matter in the water, such as decomposing plant material. This is a by-product of the disinfection process. Disinfectants are an essential element of drinking water treatment because of the barrier they provide against waterborne disease-causing microorganisms. However, disinfection byproducts (DBPs) form when disinfectants used to treat drinking water react with naturally occurring materials in the water. 

The City of Troy has and will continue to take steps to reduce the levels of THMs.

If you have any questions, please feel free to contact City Administrator Jeff Straub at 254-938-2505 or email at info@cityoftroy.us
