IDAHO SPRINGS, Colo. (CBS4)- The city of Idaho Springs is warning some of its residents about elevated levels of lead in the water supply.

City officials said the problem is not with its water mains, but with the water coming into contact with several lead-filled pipes.

Homes built between 1982 and 1989 are more likely to have pipes that contain lead.

The city is advising people to run their cold water for about 15 to 30 seconds before using it for drinking or cooking.
