Can the risk of exposure to copper or lead be reduced?
Yes. We now treat the water to reduce its natural corrosiveness to help prevent copper of lead from leaching into water from customers’ plumbing. In addition, you can help by:
Letting your cold water faucet run about 30 seconds if it has not been used for an hour or longer. This will rinse away any temporary buildup of copper, lead or other minerals that may occur in your plumbing fixtures. (Use that water for plants or washing dishes.)
Using cold water from your tap (never hot) for cooking, drinking, or making ice.
