Lead Over Time in Chicago

Chicago, as is typical of older cities, has many residences that own lead water service lines that connect to water mains in the street. Lead was used until the 1986 amendment to the Safe Drinking Water Act that banned the use of materials containing lead in public water supplies and in residences connected to public water supplies. Our current belief is that approximately 78% of all Chicago services are lead. Chicago has been proactively involved in researching the impact of lead in drinking water for over 30 years. For example, in 1976 and 1977, the City of Chicago Departments of Water Management and Health along with the World Health Organization measured lead in blood samples and home kitchen taps from 99 employees. Individual lead compliance sites have been tracked over time since 1997. The majority show a decrease in lead concentrations over time, indicating the blended phosphate addition is working well. CDWM continues to be at the forefront of lead research and has partnered with the USEPA and Chicago Department of Public Health to conduct further research studies.
