Evaluating your likely current (and near future) state of health means taking into account the risk factors — such as using chlorinated water — that affect you. Our medical diagnosis tool, The Analyst™, identifies major risk factors by asking the right questions.
Are you exposed to chlorinated water either by drinking or bathing?
Possible responses:→ Don't know
→ Yes, I use it for bathing only
→ Yes, I use it for drinking and bathing
The Environmental Working Group and US PIRG released a first ever nationwide assessment of chlorination byproducts (CBPs) in drinking water showing that more than 100,000 women are at elevated risk of miscarriage, or of having children with birth defects because of CBPs in tap water.
Montgomery County, Maryland, just outside Washington DC, leads the list for the number of pregnancies at risk in individual communities or water systems, while Texas tops the list for number of pregnancies at risk statewide.
CBPs are formed when chlorine, added to tap water to kill microbes, reacts with organic material in the water. Chlorine also reacts with organic matter, including sewage, animal waste, and soil and plant material from polluted runoff to form further harmful CBPs.
The report estimates that from 1996 though 2001, more than 16 million people in 1,258 communities were served water contaminated with CBPs for at least 12 months at levels higher than a new legal limit. A handful of large cities put the greatest number of people at risk – Washington DC suburbs, Philadelphia and Pittsburgh suburbs in Pennsylvania, and San Francisco, California – but more than 1,100 small water systems also reported potentially dangerous contaminant levels.

Chlorination destroys Vitamin E in the body, which can lead to heart problems, and has been linked to clogged arteries.
