The water that fills my hot water tank is the same water that flows through my cold water pipes. Now, there may be more metals in hot water, due to the hot water flowing through the pipes and there may be some other stuff due to the crud that can collect in an unserviced hot water heater, but I have never heard of anything intentionally being added to hot water.
