The Village of Bartlett reports that the issue stems from corrosion in household plumbing, especially homes with copper pipes, or residences built before 1986.
Bartlett’s source water, Lake Michigan, contains no detectable amounts of lead.
Officials have met with affected residents and have given them pitcher filters.
People wanting tips to reduce lead in drinking water and to learn about Bartlett's other efforts to address the lead issue are being directed to the village's website.
