lead pipes

Chicago is one of the last cities to stop using lead in the service lines. It was so widely used that it wasn't until 1986 when congress officially banned the practice that Chicago stopped using it. Now over 400,000 homes in Chicago are using lead service lines, that's 4x more than Detroit. They anticipate replacing 2,400 homes per year for 45 million per year.

Today the Chicago Tribune featured the plans and objectives of the city. You can read it here.

Is there a safe lead limit?
The EPA measures what limits of contaminants are consumable without adverse health reactions. These health goals are based on possible health risks and adequate margins of safety. In the case of lead, the EPA has ruled that zero is the maximum contaminant level for drinking water because lead is toxic and accumulates in the body over time.
