Chlorine / Chloramine (Disinfectant Residual) in your water
Health effects
Chlorine and chloramine are added by utilities to disinfect drinking water. Safe at regulated levels, but they cause taste and odor issues and can form disinfection byproducts. Carbon filtration removes them. EPA maximum residual disinfectant level (MRDL) is 4 ppm.
The guideline vs. the legal limit
The federal legal limit is the maximum allowed by law. The EWG health guideline is what independent scientists consider safe — it is often far stricter.
