How quickly is it excreted by your kidneys? And of course how much was required to give rats cancer? Cholorform is fairly volatile too so if you use a Brita for example and then have the water sitting in the Brita in the fridge a good portion of any chloroform would probably evaporate out of the water. Toxicology is complicated and you can't simply say there is some chloroform in our drinking water and it will cause cancer.

Very True. I did not mean to say that you will DEFINITLY get cancer from not filtering your drinking water. I only wanted to convey that I believe that dinking tap water is perfectly safe and the only thing that
I protect against is chlorination by-products. The levels of which are 99% of the time way below acceptable levels and in some cases not even detectable. But as we are not apprised of the amounts of chlorine being introduced into our water on a daily basis, periods with elevated levels of organics in the water supply require higher concentrations of Chlorine to be added to achieve acceptable levels of disinfection. This
CAN cause the THM levels in our water supply to increase. It is a very complex issue and there is a wealth of good and even more bad information out there on drinking water safety. Here's a link if you want to learn everything you could ever want to know.
Take things for what they are worth and do your own research from reputable sources before you believe something some anonymous person tells you on some website!
