Our bodies are 70 percent water; water is the foundation of our health. However, new pollutants and organisms are entering our water supply every day, and these new contaminants pose a stiff challenge for our water-treatment facilities. Organisms like cryptosporidium can be fatal and often slip past conventional treatments. Besides the ever-present threat of heavy metals and chemicals, new compounds like chloramines, trihalomethanes, MTBE, and endocrine-disrupting chemicals (EDCs) are a real threat to our long-term health. Find out just how many health-threatening contaminants are in your water right now. And find out how to best remove them from your water in your own home.
