GAC to BAC: Does it make chloraminated drinking water safer?

WATER RESEARCH, 172.

By: A. Cuthbertson*, S. Kimura*, H. Liberatore*, D. Knappe n, B. Stanford*, R. Summers*, E. Dickenson*, J. Maness n ...

author keywords: Biological activated carbon; Drinking water; Disinfection by-products; GAC; Total organic halogen; Calculated cytotoxicity & genotoxicity
