The Franklin Water Management Department reported elevated levels of total trihalomethanes, which are a byproduct of chlorination that reduces the risk of microbial life in drinking water, according to the city notice. The elevated levels were found in a small area of the city on Carr Avenue, located south of downtown Franklin adjacent to Columbia Avenue.
In that area, city testing—which is completed quarterly as required by the state—found levels of total trihalomethanes to be 0.093 milligrams per liter. The maximum level is 0.08 milligrams per liter, according to the notice.
While the city is required to report the results of the testing, residents do not need to boil their water or take any other action. According to the letter to residents, the elevated levels are believed to be a result of poor water circulation in that area, and the city began work in mid-February to extend water lines in that region for better circulation. Construction on the lines should be complete in March, according to the city.
“The city is committed to providing the highest quality water,” the letter said. “We’ve recently completed multi-million-dollar upgrades to our water treatment facility with a state-of-the-art process. We closely monitor the quality of water we produce including multiple tests per day of the water produced at our treatment plant. The city has consistently scored high in our sanitary survey. This survey is performed randomly on a periodic basis and we have scored in the “Approved Category” for several consecutive sanitary evaluation periods.”
