Lead is Main Contaminant of Concern
It is a toxic metal that is harmful if inhaled or ingested and can pose serious health risks, particularly to children under 7 years old, as well as pregnant women and nursing mothers. For information on how to protect your family from lead hazards, visit EPA’s Fact Sheet.
Residential Lead Testing Opportunity
If your residential property has not been tested by EPA, contact us today about yard soil and private, drinking water well testing. At this time, residential yard soils and child high-use areas may be eligible for no cost remediation (cleanup) by EPA.
- Call EPA’s testing/sampling contractor, Tetra Tech, at 573-358-8772; or
- Contact EPA Remedial Project Manager (RPM) Sarah Hensley at 913-551-7241 or hensley.sarah@epa.gov.
Annual Childhood Lead Testing
EPA encourages parents and caregivers to have children under 7 years old tested for elevated blood lead levels annually. The only way to know if your child has an elevated blood lead level is to have his or her blood tested; lead-poisoned children do not always look or act sick. Talk to your pediatrician, general physician, St. Francois County Health Center (1025 West Main St., Park Hills, MO 63601; 573-431-1947), or other health care professionals about testing your child and to arrange for blood lead screening.
