Comment-19815-Mr. Marc William Goff Sr

Data from research studies indicate that several HAAs, e.g., dichloroacetic acid and trichloroacetic acid, may be carcinogenic in laboratory animals. Exposure to other HAAs has also been associated with reproductive and developmental effects in laboratory animals. The current Maximum Contaminant Level (MCL) set for HAA5 is because of concern that exposure to HAAs over many years may increase the risk of cancer.
