‘These levels are crazy’: Louisiana tap water sees huge spike in toxic chemicals

Encroaching water from the Mississippi River has necessitated more thorough disinfecting, which leaves behind dangerous chemicals

The water for a community along Louisiana's Gulf coast has seen a significant increase in the levels of contaminants known as disinfection byproducts, according to recent state water tests reviewed by the Guardian. According to the Environmental Protection Agency (EPA), long-term exposure to such substances poses an increased risk of cancer.

The findings have emerged as many residents along Louisiana's southern coast have faced saltwater intrusion from the Gulf of Mexico.
