BROKEN ARROW — A water treatment mishap by the city’s supplier has led to a sharp increase of two common but potentially carcinogenic groups of chemicals in Broken Arrow’s tap water, officials said.
The chemicals, created when chlorine interacts with organic matter, have increased to near federal limits because of a change in the chemical mixture used to treat the water before it reaches the city, Broken Arrow Engineering Director Kenny Schwab said.
The new mixture has allowed more organic matter to remain in the water, which interacts with additional chlorine that is added when the water reaches Broken Arrow, he said.
The city’s supplier, the Oklahoma Ordnance Works Authority of Pryor, has since reverted to its previous method, and levels of chlorine by-products have been dropping, he said.
