Childhood Blood Lead Levels in South Carolina
Why blood lead screening matters
A child's blood lead level is the most direct way to know if they've been exposed to lead—whether from drinking water, paint, dust, or soil. Even levels once considered "safe" can affect brain development and learning. South Carolina tracks these levels statewide to identify children at risk and help families take action.
South Carolina's screening program
The South Carolina Department of Health and Environmental Control (DHEC) oversees blood lead surveillance for children across the state. Medicaid covers screening for all enrolled children; private insurance and uninsured children may access testing through local health departments or pediatricians.
The state collects reported blood lead results from laboratories and healthcare providers. This data helps public health officials spot geographic hotspots and track whether exposures are declining over time. However, not all children are screened—coverage varies by age, insurance, and access to testing.
What the data shows
CDC tracks the percentage of tested children with elevated blood lead levels (5 micrograms per deciliter or higher) by county. These county-level percentages are publicly available and help residents understand local lead exposure risk. If you want to see your county's most recent data, visit the CDC's Healthy Homes and Lead Poisoning Prevention website.
Getting local data
To request detailed blood lead surveillance data for your county or to learn about screening availability in your area:
- Contact DHEC's Lead Poisoning Prevention Program at the South Carolina Department of Health and Environmental Control
- Ask your pediatrician about screening recommendations for your child's age and exposure risk
- Call your local county health department for nearby testing sites
State-level data releases are typically annual. DHEC can tell you whether your county has seen changes in childhood lead exposure over time.
Not just drinking water
While lead service lines in older homes are a real concern, children are exposed to lead from multiple sources: interior paint dust (common in homes built before 1978), contaminated soil, certain imported toys and spices, and occupational dust brought home on parents' clothes. A water test and home assessment work together to reduce overall exposure.

Next steps for residents
- Request a blood lead test for your child through your pediatrician or local health department if your home was built before 1978 or you live in a historically industrial area
- Contact DHEC to ask whether your county has recent surveillance data and what it shows
- Ask your water utility whether your address is served by a lead service line and request a free or low-cost water test
- Visit CDC's lead resources for home safety steps that reduce dust and paint hazards
