Your water is continuously tested and monitored to ensure that it is safe for consumption. I was offered to have my water tested by an individual that wants to sell me a product. A single colorimetric test should not be used to provide the basis for safety claims. Assertions regarding water safety should be ignored when an individual wants to sell you something based on a single, quick, and cheap colorimetric water test. Many studies have shown that the amount of chlorine found in treated water is safe to drink.
Chlorine is needed to maintain disinfection throughout the water distribution system.
The potential for risk from microbial contamination outweighs any risk associated with chlorine. No, not without further treatment. Aluminum, fluoride, and chloramine are examples of substances that are not acceptable in water used for kidney dialysis. Kidney dialysis centers are knowledgeable about water quality issues. Always consult with your doctor on this matter.
