Due to Environmental Protection Agency (E.P.A.) regulations requiring water utilities to control levels of regulated disinfection byproducts (DBP’s), the City of Vandalia will soon be using chloramines and not chlorine to disinfect drinking water.
The DBPs typically form when chlorine mixes with small quantities of natural organics commonly found in surface water but not groundwater.
Chloramines will produce lower concentrations of regulated DBPs than chlorine as it has trace amounts of ammonia, which will improve water quality and ensure the public water system continues to comply with the EPA’s increasing stringent regulations on drinking water.
Chloramination is expected to improve the taste and smell of the water delivered through the system. Water Plant officials do say there may be an unfamiliar odor or taste for a few days when the change from chlorine to chloramines first occurs.
The move joins Vandalia with nearby communities like Bowling Green, Farber, and Perry, who are all treating their supply with chloramines.
It will also help the city to officially use the Clarence Cannon Wholesale Water Commission as a backup supply in case the power goes out.
The Women’s Eastern Reception, Diagnostic, Correctional Center (W.E.R.D.C.C.) has its water treated with chloramines and is a customer of the City of Vandalia but has its water pumped from Clarence Cannon.
