Study: Disinfection Byproducts in Drinking Water May Increase Risk of Low Birth Weight Infants

Pregnant women exposed to low levels of disinfection byproducts in chlorinated drinking water were more likely to give birth to underweight babies, according to a recent peer-reviewed study based in Sweden. The risk increased with the levels of disinfection byproducts in the water.

Disinfectants in water systems are necessary to prevent the spread of microbial diseases like dysentery and cholera. But unintended byproducts form when the disinfectants mix with organic material like plant matter, animal waste and runoff. These disinfection byproducts are associated with cancer and harm to the developing fetus.
