Dichloroacetic acid
Sun Valley Gid
NOTE: Sun Valley Gid purchases water from Truckee Meadows Water Authority which is required to test for dichloroacetic acid. Sample information shown below was taken by Truckee Meadows Water Authority.
Dichloroacetic acid, one of the group of five haloacetic acids regulated by federal standards, is formed when chlorine or other disinfectants are used to treat drinking water. Haloacetic acids and other disinfection byproducts increase the risk of cancer and may cause problems during pregnancy. Click here to read more about disinfection byproducts.

State and national drinking water standards and health guidelines
EWG Health Guideline 0.7 ppb
The EWG Health Guideline of 0.7 ppb for dichloroacetic acid was defined by the Environmental Protection Agency as a one-in-a-million lifetime risk of cancer. Values greater than one-in-a-million cancer risk level can result in increased cancer cases above one in a million people.
