Mayor Michael Mullen confirmed Thursday evening that C8 has been detected in Marietta’s water. Finished water was found to contain the manufacturing substance in a concentration of 10 parts per trillion.
Safety Service Director Dave Sands said it’s important to remember that the level detected in Marietta’s water is 50 times lower than the interim action level established by EPA, which is 0.5 parts per billion.
Mullen stressed that the results received by phone were preliminary and not a final written report, which is expected within days. He said the results have been submitted to the Ohio Environmental Protection Agency and West Virginia Department of Environmental Protection.
Sands said the city’s wells were tested and results ranged from non-detect to 18 parts per trillion.
