Lead
Lead poisoning remains a major issue in Philadelphia. In 2022, 6% of children screened by the Philadelphia Public Health Department had elevated blood lead levels. Non-Hispanic Black children have the highest rates of lead exposure. Since 1995, faculty affiliated with the CEC designed and implemented a service learning course for Penn students called “Speaking about Lead in West Philadelphia.” Richard Pepino, the former Deputy Director of the CEC, and now Maria Antonio-Andrews, CEET member, have taught the course to Penn students who bring the content to Philadelphia elementary students. Collection and testing of thousands of soil samples for lead have occurred through this course and other individual student projects. This data formed the foundation for our lead soil map.
Lead Soil Map
CEC has worked with healthcare professionals, governmental entities, students, and communities to consolidate historic lead soil data and collect samples of soil to test for lead contamination using a Delta X-Ray Fluorescence (XRF) portable analyzer. We currently have over 3,900 soil samples in 86% of the census tracts in Philadelphia. Explore the map below. Each colored point on the map represents one soil sample. In cities like Philadelphia where there are multiple sources of lead exposure, the EPA considers 100 ppm as the maximum lead soil level for children’s play areas.
Disclaimer: These points may not be exact. Locations are sometimes estimates based on near addresses or cross streets. Also, lead soil levels vary greatly even within inches. Any high or low lead level in soil may not represent the lead risk of the entire property.
Get Involved
Are you interested in having the soil in your yard tested for lead? Review the video on how to collect a sample and contact us. We would also love your help obtaining soil samples in neighborhoods in Philadelphia that have not yet been tested! If you would like to help, all you need is a plastic spoon, a permanent marker, and a clean plastic bag.
