The city of Peabody is making major upgrades to its two main water treatment plants after test results showed the city’s system does not conform to tougher new Environmental Protection Agency drinking water standards.
The Department of Environmental Protection has notified the city that there is no imminent health risk to the community.
According to a notice from the mayor’s office in April, city officials were notified in 2007 that the EPA was revising its testing for disinfection byproducts in drinking water, substances that can form when water is treated with chlorine, as Peabody’s drinking water currently is. These substances are called trihalomethanes.
The agency revisions, which took effect in 2012, mandated more rigorous testing, which is conducted every quarter. The results in Peabody meant that improvements to the Winona and Coolidge water treatment facilities were required. Full story for BostonGlobe.com subscribers.
