Why is the water a reddish brown color?
The chlorine added to the water to kill the bacteria may also react with the iron that has deposited in the water mains, breaking it loose from the pipes and causing some temporary discoloration of the water. The iron in the water causes a distinctive reddish brown color but does not present a health threat. Flushing fire hydrants and inside taps will help eliminate the iron residue and associated color problems.
