EWG Health Guideline 0.5 ppb

The EWG Health Guideline of 0.5 ppb for trichloroacetic 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.
