Lead can cause serious health problems, especially for pregnant people and young children.
Madison Heights periodically tests tap water in homes for lead and copper, city officials said. A recent sample from 30 homes with lead service lines showed the 90th percentile for Madison Heights is 18 parts per billion -- exceeding the action level of 12 ppb, which measures corrosion control effectiveness.
The action level is not a health-based standard. The goal for lead in drinking water is 0 ppb because there’s no safe level of lead in the blood.
City officials said an action level exceedance is when more than 10% of the 30 homes tested have results over 12 ppb. This sample brought back seven homes exceeding that level, which is 23%.
As a result, officials are reaching out to customers and performing ongoing sampling every six months, as well as replacing the service line pipe that connects some homes to the water main.
Homes with lead service lines have a greater risk of high lead levels because lead can enter drinking water when the water touches pipes, solder, interior plumbing, fittings, and fixtures that contain lead, according to Madison Heights.
