It is a very idealistic and somewhat exaggerated statement. I wrote the first disinfection byproducts THM regulation at USEPA, so I know chlorine and DBPs very well. The THM regulation has often been misunderstood. Bladder cancer incidence in the US and Canada has not changed in the 40 years since the regulations, and the repro/developmental speculation is not supportable by the many studies in animals and human epi. . I looked at 6 other countries too. THMs is really a surrogate indicator regulation. The THMs are not carcinogenic in animal bioassays in water. I have a couple of papers on it coming out soon in JAWWA and Dose-Response Journal, and I am presenting tomorrow at the Water Quality Technology Conference in Toronto. All disinfectants have limitations. Chlorine has saved millions of lives since its introduction in the early 20th century. Chlorine dioxide has a lot more problems than you suggest. Read my coming papers or contact me.
