This substance is potentially carcinogenic. Place water filters on your sinks and showers. These are rather inexpensive. I use Rainshow’r or E-Water filters on the showers. A hot shower exposes the body to more chlorine than eight glasses of tap water. We recommend PUR or BRITA filters on the sinks. Use this filtered water to wash your face and brush your teeth, to wash and rinse vegetables and fruits, to steam vegetables, and to cook rice, beans and pasta. Do not drink unfiltered tap water.
