When you buy gasoline and indoor house paint today, you’ll see “unleaded” or “lead free”. Unfortunately, this wasn’t always the case. It once was standard for all paints and gasoline to have lead, which found its way into our air, soil and the mouths of children.
Even though these leaded products are now banned, our children are still dealing with the consequences of our actions from years past. Children are most often exposed by eating chipping and deteriorating paint inside older homes.
It is vital that caregivers and pregnant people understand how their children can be exposed to lead and how to prevent it. We developed this page to help you identify common sources of lead, and available programs in our region to help children avoid or reduce exposure to lead.
Lead and children's health
Despite the average blood lead levels in children declining since 1980, lead exposure is still one of biggest childhood environmental health issues.
Children can get lead exposure from:
- their mother during pregnancy;
- dust in homes containing lead paint;
- outdoor soil and dirt that contains historic deposits of lead from gasoline; and/or
- contaminated drinking water if the pipe, solder and/or fixtures contain lead.
Lead exposure reduces child cognitive function and increases behavioral problems. This may limit children from reaching their full developmental potential. Lead exposure during pregnancy may also increase the risk of preterm birth and reduce fetal growth.
Studies show that children have higher blood lead levels in summer. In warm weather, windows (often painted with lead-based paint) are opened and closed more. This leads to increased lead dust in the air and on the ground.

If you live in a home built before 1978, hire certified professionals to remove peeling or chipped lead-based paint. For a list of lead-certified contractors near you, visit this website.
Wet-mop your floors, around windows and surfaces where lead dust may accumulate.
Wash children’s hands regularly, especially after they play in dusty areas or outside soil. There is lead contamination in much of the Philadelphia region’s soil.
Determine if you have a lead service line in your home. Follow the steps outlined in this video.
If you have a lead service line, let the water run for 1 minute for every 50 feet your kitchen sink is from the middle of the street, before using the water.
Do this every morning and when your pipes have not been in use for more than 6 hours.
Consider buying a water filter for drinking water and cooking.

Imagine a Day Without Clean Water: Middle School English Language Learners Advocate for Clean Water for All
This curriculum was written by Sondra Gonzalez as part of Dr. Howarth’s class for the Teachers Institute of Philadelphia for middle school English language learners and will help students gain knowledge about the water cycle, worldwide water quality, common contaminants, and the drinking water treatment process in the United States.
Workshops and Continuing Education for Researchers
To enhance basic research skills that pertain to children’s environmental health, we will strongly encourage early-stage investigators and researchers to enroll in workshops and continuing education courses.
