Childhood Blood Lead Surveillance Data — Montana

Overview

Montana's Department of Public Health and Human Services (DPHHS) tracks blood lead levels in children through its public health surveillance system. This data helps identify communities where children may be exposed to lead—whether from drinking water, paint, soil, or other sources.

If you're concerned about lead exposure in your home or community, understanding what screening data shows can help guide next steps.

How Montana monitors childhood lead exposure

Montana requires laboratories to report blood lead test results for children under 18 to the state health department. The CDC considers a blood lead level of 3.5 micrograms per deciliter (µg/dL) or higher in children as elevated and worthy of follow-up.

The state collects this data at the county level, allowing public health officials to spot patterns and target prevention efforts. However, not all children in Montana are screened regularly. Medicaid covers blood lead screening for enrolled children, but screening rates vary by county and depend on whether a child's doctor orders the test.

Accessing Montana's blood lead data

To request childhood blood lead surveillance data for your county or community, contact:

Montana DPHHS, Office of Epidemiology and Scientific Support Contact your local county health department or the state health department directly to ask about recent surveillance reports or data summaries.

Data is typically available in summary form (counts and percentages by county) rather than individual test results. Response times vary; allow 2–4 weeks for custom data requests.

What the data tells you

County-level percentages of elevated blood lead results can reveal whether children in your area face higher-than-typical exposure risk. A higher percentage does not automatically mean your home has a lead problem—it signals that screening should be a priority and that sources (water, paint, soil) may warrant investigation.

Next steps for residents

  • Ask your child's doctor about blood lead screening, especially if your home was built before 1978 (when lead paint was banned) or if you live in an older neighborhood.
  • Contact your county health department to ask whether childhood lead screening is recommended in your area and where to get tested.
  • Request a water test if you suspect lead in drinking water; your local water utility can advise on lead testing kits.
  • Visit the Montana DPHHS website or call 406-444-0273 to ask about recent childhood lead surveillance findings in your county.

Common questions

What is a normal blood lead level for children?

The CDC considers 3.5 µg/dL or higher as elevated in children under 18. Lower is always better—there is no truly safe level, which is why screening matters. A pediatrician can explain your child's test results.

Is my child automatically tested for lead in Montana?

Not automatically. Medicaid covers screening for enrolled children if a doctor orders it, but testing depends on your doctor recognizing the risk and requesting the test. Ask your pediatrician whether screening is appropriate for your child.

Can I find out how many kids in my county have high lead levels?

Yes. The Montana DPHHS tracks county-level data and can provide summary statistics. Contact your local county health department or call the state health department at 406-444-0273 to request recent reports.

Does high childhood lead in my county mean my water has lead?

Not necessarily. Children are exposed to lead from multiple sources: old paint, dust, soil, and water. High childhood lead levels signal that screening and source investigation are important, but you'll need to test your home's water separately to know if that's a contributor.
