Residents of Concord were caught off guard after learning the city’s drinking water violated EPA standards.
A test found the level of haloacetic acids in the water reached .0624 mg/L.
The limit is .060 mg/L.
WSOC-TV reported that the city of Concord does not treat all of its own water, and the 2 million gallons per day that come from an undisclosed source is the cause of the increased levels of haloacetic acid.
According to the Independent Tribune, haloacetic acids form in water as a by-product of the disinfection process. Concord uses chlorine to disinfect its drinking water, which reacts with organic matter such as leaves to create haloacetic acids.
The statement released by the city of Concord said the water is safe to drink, but those who are elderly or have infants may want to consider contacting their health care providers as a precaution.
In cases where high amounts haloacetic acids were consumed over short periods of time people experienced skin irritation, according to Livestrong.com.
Although it has not been tested or confirmed in humans, animals who consumed high amounts of haloacetic acids were at higher risk for cancer and birth defects according to the website.
