What do you think about tap water that may contain chlorine and fluoride?

Chlorine is added to tap water to kill pathogens such as bacteria and viruses by breaking the chemical bonds in their molecules. Putting your tap water through a water filter will reduce chlorine, but I read they are potentially not effective at removing VOCs, heavy metals, endocrine disruptors or fluoride. I recommend you read this article about water filters: www.greenamerica.org/livinggreen/waterfilters.cfmYou can do a bunch of tests on your tap water to ensure it is safe like checking the PH level. If your tap water has any color or smell to it your best bet is bottled water. Surprisingly, most bottled water brands have a acidic PH. There are videos on YouTube showing the best brands according to PH levels.

Most large cities stopped using chlorine around 15-20 years ago, and switched to chloramine injection instead. You can't filter chloramines out of tap water with any kind of filter that you can easily get; it takes something on the order of a dialysis filter (large filter stack, and a long dwell-time in the activated carbon.) Anything less than that and you aren't removing the chloramines. You can't boil them out. The simplest method to remove chloramines from drinking water is the addition of about 100mg of ascorbic acid (vitamin C) per gallon of water, according to Wikipedia on 'chloramine'. I drink bottled spring water instead of relying on chemical reduction or inefficient/slow filtration methods. For situations where I absolutely have to use tap water, I bought 1000mg ascorbic acid supplements in gel caps at the Farmers Market so that I can easily dice it down to 100mg/gallon. Wiki says that fish fanciers use between .1-.3 grams of sodium thiosulfate per 10L of water to de-chlorinate the water for their fish, so pet stores ought to carry that. The ascorbic acid ought to be AIP-friendly, and I doubt the sodium thiosulfate is. Your Brita filter is utterly worthless, per a review of 7 different popular filtration systems I'd read elsewhere. The only thing the Brita did was to increase the amount of aluminum in the test sample, instead of removing it. The other contaminants were reduced by something like 5 to 15% for the Brita, which truthfully isn't worth bothering with. The ZeroWater filter (www.zerowater.com) was the only one tested that removed >99% of pollutants; the rest fared A LOT worse, on the order of 5-30% reduction, or an INCREASE in the pollutant (as with aluminum in 4 out of the 7 tested.) If you really want to have fun scaring yourself about local tap water, check out the Environmental Working Group's tap water database, www.ewg.org/tapwater/It looks like my local city water exceeds the best-guess limits (not the laughable EPA limits) for 10 contaminants, and has 23 other contaminants that I don't ever want to be drinking. Yeah, there are ALL sorts of reasons that I've been drinking bottled spring water for nearly 30 years, now.
