Copper corroded from pipes may cause a metallic taste in drinking water. Iron, a metal not known to be harmful, may also cause a metallic taste. Corrosion of faucets, leaks in pipes, premature failure of hot water heater tanks, and other similar problems may be caused by corrosive water. Although your water does not exhibit symptoms of severe corrosivity , you may still have unacceptable levels of lead or copper dissolving into your drinking water. Continue through the chart to evaluate your risk of copper contamination.
Copper pipes are reddish-colored metal pipes that are often used to carry water through homes.
Copper testing can be done at many laboratories. Wisconsin conducts a certification program for water testing laboratories. The Wisconsin Department of Health and Family Services recommends that you choose a certified lab, since they must meet certain quality standards. Infants and children are particularly sensitive to elevated copper levels in water. Above this level, public water supplies must find ways to reduce copper levels in drinking water.
