Aqua conducting annual chlorine treatment in Danville area

DANVILLE — Customers of Aqua Illinois Inc. in the Danville area may experience a slight chlorine taste in their water beginning July 1 due to a routine water treatment, according to company officials.

From July 1 to July 31, Aqua will use free chlorine as its primary disinfectant instead of chloramines, which are disinfectants used to treat drinking water and are most commonly formed when ammonia is added to chlorine, according to the United States Environmental Protection Agency. Chloramines provide longer-lasting water treatment as the water moves through pipes to consumers, according to the EPA, and this type of disinfection is known as secondary disinfection. Many utilities use chlorine as their secondary disinfectant, according to the EPA, but in recent years, some have changed their secondary disinfectant to chloramines to meet the EPA's disinfection by-product regulations.

According to the EPA, chloramines have been used by water utilities for nearly 90 years, and are highly regulated. Water that contains chloramines and meets the regulatory standards is safe to use for drinking, cooking, bathing and other household uses.

According to Aqua officials, switching to chlorine for July is a routine procedure that the company has done several times in the past. During this period, some customers may detect a slight chlorine taste in the water. This will affect residents in Danville, Tilton, the Lake Boulevard area north of Danville and the Hooton area.

Aqua officials emphasized that there is no health risk associated with this temporary procedure.
