Disinfectants in tap water

Disinfectants in tap water

It seems that which is used to 'clean' tap water is that which also produces adverse health effects.

In order to prevent microbiological contamination, governmental programs have treated tap water with a variety of disinfectants. These chemicals, like chlorine and chlorine dioxide, may mix with organic and inorganic matter within water to create 'disinfection by-products', or DBPs. The most abundant by-products are trihalomethanes, or THMs.

Although studying the exact effects of these by-products has proven difficult, researchers have determined at least two specific health effects: increased bladder cancer risk and congenital abnormalities, or birth defects.

The following articles from scientific journals provide further information about THMs:
