Like chlorine, chloramines in water used for dialysis would be toxic and must be removed. Medical centers performing dialysis are responsible for preparing the water that enters the dialysis machines. Like you, they are being notified of this change.
Kidney dialysis patients can safely drink, cook and bathe in chloraminated water. Chloramines are only harmful if they directly enter the bloodstream. Since water comes in contact with the bloodstream during hemodialysis, very strict water purification standards are already being followed by the kidney dialysis industry.
Water purification techniques used for kidney dialysis are already designed to remove both chlorine and chloramines. Industry standards require that a nurse, technician or trained caregiver test for both chlorine and chloramines after the purification process to ensure that these chemicals have been removed from the water before it can be used in a dialysis machine.
