The Environmental Working Group and U.S. Public interest Research Group admit that adding chlorine to tap water saves thousands of lives each year by reducing the number of harmful bacteria. However they say that this process itself actually creates hundreds of toxic chemicals called “chlorination by products, or CBPs. Many cities small and large have reported potentially dangerous levels of CBPs in their tap water over the past six years, according to the report. In total, the investigations list 42 cities-both large and small-that expose pregnant women each year to trihalomethanes (THM), the most common toxic chlorination by product.
A new standard by the Environmental Protection Agency went into effect that will lower the allowed levels of chlorination by-products, including THMs.
However the investigators list multiple cities with lower levels of THM in tap water that they say still expose thousands of women to potentially serious and dangerous toxins during their pregnancy!!! Recent studies have linked toxic chlorine by-products to reproduction risks! In other studies his group found CBPs could affect a baby’s birth weight and pointed to risks of dangerous birth defects and miscarriage.
