Science, Studies, and Reports

A new study by Johns Hopkins University, published in the peer-reviewed journal Environmental Sciences & Technology. found that several toxic and carcinogenic byproducts may be present in drinking water treated with chlorine. Researchers discovered that when chlorine combines with phenols, which can occur naturally in water, a variety of byproducts result, including two forms of the toxic carcinogen BDA. Some of the byproducts are already treated by most water utilities, but others are unregulated, and may pose risks to long-term health. USA Today
