Copper and Drinking Water
The copper content of drinking water depends on the type of pipe it flows through (very often copper) and the hardness of the water itself. Hard water tends to coat the insides of the pipes and provide a protective barrier between the water and the copper pipes. The copper content in hot water is generally higher than in cold mains-water because of the increased solubility of copper at high temperatures.
It is possible to buy a water filter through which all drinking water is passed. This is worth doing because too much copper reduces the availability of zinc to the body and most of us are already rather short of zinc.
You should never fill the kettle or drink the water from the hot-water tap, as it can be very high in copper.
