EPA is asking residential property owners for access to conduct free lead contamination sampling (testing) of residential yard soils and private drinking water wells. If your residential property has been tested and is eligible for remediation [400 parts per million (ppm) lead or higher in soil], EPA’s contractor will perform the cleanup for free. Residential properties also include child high-use areas such as child care facilities, parks and playgrounds. In addition, if you own property along the Big River or within the Big River floodplain, EPA is also asking to conduct free testing. Sampling and residential cleanup is performed at no cost to property owners. To schedule your property or private well for free testing. please contact EPA (contact information below) or TetraTech, EPA’s contractor, at 636-797-8446.

Lead is a toxic metal that is harmful if inhaled or swallowed. Lead exposure can cause a range of adverse health effects for children and adults, from lifelong behavioral disorders and learning disabilities to seizures and death, putting young children at the greatest risk because their brains and nervous systems are still developing. Children 7 years old and younger are most at risk from developing health effects from exposure to lead. It is important that children in this age range be tested annually. Your doctor can do a simple blood test to check your child, or you, for lead exposure. Talk to your pediatrician, general physician, or the Jefferson County Health Department by phone at 636-797-3737 or at one of their locations: Hillsboro, 405 Main Street; Arnold, 1818 Lonedell Road; or High Ridge, 5684 State Road PP.
