Okay, Mister Waterman. I am going to reply to your sarcastic and demeaning comments (“Based on your fact-filled post above…”, etc.). ONCE. And then I’m not going to tangle with you after that. I could be wrong, but you sound like you are someone who is involved with chloramine professionally somehow and has a stake in making me look stupid.
You wrote, “Did you actually read the IRIS report which basically states that there is no conclusive evidence of long-term carcinogenic or cancer effects…” Yes. (And again, I don’t deserve your sarcasm and sneering you-know-nothing words and tone.) For cancer in humans AND animals it says, “Inadequate.” That means they haven’t done enough studies to determine if chloramine causes cancer, which is what I said. I also wrote, “However, some of the data shows that is does.” One of the studies in the IRIS says there is an association between occurrence of mononuclear leukemia in female rats and consumption of chloraminated water. Maybe if they did a reasonable amount of cancer research, informed citizens wouldn’t feel like guinea pigs in your big chloramine experiment.
You wrote, “Chloramines have been used to disinfect public water systems for over 90 years.” Okay, now I know who you are- no one else brings up Denver. It comes originally from the SFPUC, where the first group of citizens rose up against chloramine. What you also know but aren’t sharing- but hey, maybe you don’t know- is that until 2005, Denver used 0.5 to 0.8 mg/L of chloramine in their water, for taste and odor control only. Since 2005, when Denver upped the dosage to what all the places that chloraminate use, people from Denver have been reporting skin, respiratory and digestive symptoms.
ALL you water treatment guys/EPA/health departments have to back up your claim that chloramine is perfectly safe is that there aren’t any studies saying it isn’t safe it must be okay to use (when you know darn well there are no studies period!), and it’s been used since the Stone Age and no one’s complained. ANECDOTAL. Yet you think it’s fine to put chloramine in our drinking water and let us bathe in it, drink it, cook with it, feed our babies with it, wash our clothes in it, brush our teeth in it, year in and year out. Wow.
Did you know that one of the things they found out in the Zierler et al study you referred to was in the town they used for a control, they discovered there were more deaths from pneumonia than in the town they were studying? Are you aware that the control town uses chloraminated water? WHY was there never any follow-up research on that, given SO many people in the U.S. suffer from respiratory symptoms when exposed to chloraminated steam in the shower, on the stove, from the dishwasher, washing machine, dryer, etc. and also from aerosols in the shower? Are you aware of Dr. Richard Bull’s experiment where he put mice in a beaker of chloraminated water to see what would happen to their skin, but before 10 minutes was gone every one of them was dead from respiratory distress?
You said, "Your “cheap way to meet a relatively new and quite stupid EPA disinfection byproduct rule is a particularly concise and effective statement of absolute ignorance.” WhOA! You are SO hostile! I said, “More and more water treatment facilities are using it because it is a cheap way to meet a relatively new and quite stupid EPA disinfection byproduct rule.” You sure are "the woman who DOTH protest too much! Enough to misquote me all over the place! Wow!
You sneer at me and call me stupid, but I am not. The EPA rule IS a stupid one because the EPA has recommended using chloramine, which has its own set of disinfection byproducts (DBPs), many of which are 100 to 10,000 times more toxic than trihalomethanes and halo acetic acids, and NONE of them are regulated, which means, anyone else who reads this, they don’t have to test your drinking water for them. You could be drinking and bathing in dodo acids, which CHANGE DNA, o NDMA, which is a highly toxic and known carcinogen. Haloaceto nitriles (http://www.vce.org/ChloramineScience/NitrogenDBPs.pdf) is another one. But you’ll never know, because no one is testing for them. What are you going to do, Mister Waterman, when the EPA regulates those and some of the other more toxic of chloramine’s DBPs and your precious chloramine system has to go down the tubes and you have to go to something else, like the TOC pre-filtriton you should have done in the first place?
