5.2.9.13: Testing for and Remediating Lead Hazards

Lead can be found in all parts of our environment-the air, the soil, the water, and even inside our homes. Because of the highly toxic nature of lead, early care and education (ECE) programs should test and remediate lead hazards in paint and dust, water, soil, and consumer products.

Paint and Dust: Paint and other surface-coating materials used in ECE facilities, including family child care homes (both rental and owned), should be labeled for residential (not industrial) applications only.

All ECE facilities built before 1978

• Should be inspected and tested for lead-based paint hazards by a certified lead inspector or certified risk assessor for the following reasons 
  • If lead is identified in either the interior or exterior paint of the facility, ECE facilities should consult their state or local childhood lead poisoning prevention program, public health agency, and/or a certified risk assessor to determine the best steps for lead hazard control work.
  • Surfaces found to have lead-based paint hazards should not be used and should be made inaccessible to children and staff until remediated.
  • ECE facilities should hire a certified lead abatement contractor to do lead hazard control work. ECE facilities should be sure to test for lead dust clearance to ensure proper cleanup was done after lead hazard control work. 
  • ECE facilities should implement an occupant protection plan during lead remediation work.
• Should conduct annual inspections of paint and perform routine maintenance to ensure that paint remains intact 
• Should use an Environmental Protection Agency (EPA)-certified lead-safe contractor (also known as a renovation, repair, and painting, or RRP, contractor) if any repair or renovation work (not lead hazard control work) is needed

Water: ECE facilities should learn the source (public or private) of their water and determine whether the facility has a lead service line or lead-containing pipes, fixtures, or solder. They should test water for lead and take steps to remediate sources if the water contains lead.

Soil: Bare soil around ECE facilities should be tested by an EPA-recognized National Lead Laboratory Accreditation Laboratory (NLLAP) or covered with mulch, plantings, or grass.

Consumer Products: Caregivers/teachers should check the U.S. Consumer Product Safety Commission’s website (http://www.cpsc.gov) for warnings of potential lead exposure to children and recalls of play equipment, toys (especially antique and imported), jewelry used for play, imported vinyl mini-blinds, and food contact materials. If they are found to have lead, the items should be removed from the facility.

Only a certified lab can accurately test toys and products for lead contamination. “Test it yourself” kits or lead wipes (often purchased online or from large home improvement stores) are not recommended. Kits and wipes do not show how much lead is present, and their reliability at detecting low levels of lead has not been established.

Caregivers/teachers should not give children in their care imported candy, herbal remedies, or folk medicines.

RATIONALE

Lead is especially dangerous to children, because their brains and nervous systems are more sensitive to lead’s damaging effects, and their young bodies are able to absorb more lead. Plus, babies and young children often put their hands and other objects in their mouths. These objects may have lead dust on them, particularly if a child is crawling on floors contaminated with lead dust. Once ingested, lead competes with calcium and can be stored in bones, teeth, and organs for decades, making lead poisoning difficult to treat. Lead-based paint is the most common source of lead exposure and poisoning in children.^1,2

Children under the age of 6 are at the greatest risk for lead poisoning. Most children with lead poisoning do not look or act sick. A blood lead test is the only way to know if children are being lead poisoned. The U.S. Centers for Disease Control and Prevention (CDC) uses a blood lead reference value of 5 micrograms per deciliter (mcg/dL) to identify children with blood lead levels that are much higher than most children’s levels.^3,4 Lead is a neurotoxin. Even at low levels of exposure, children can suffer seriously from lead poisoning, leading to behavior and learning problems, lower IQ, hyperactivity, slowed growth, hearing problems, and anemia. There is no safe blood lead level in children.⁵

Lead may be present in paint, dust, water, or soil. It may also be present in consumer products like food, candies, spices, pottery/dishes, traditional medicines, cosmetics, toys, jewelry, and painted furniture.

Paint and Dust:The manufacture of residential lead-based paint was banned in the United States in 1978, but many older homes around the country still contain it. When lead-based paint inside a home deteriorates or is located on a friction surface, chips and dust settle on surfaces children can easily reach, such as windowsills and floors. Contaminated dust can be inhaled or ingested and is hazardous even if the particles are too small to see. 

Water:ECE facilities built after 1986 likely do not have a lead service line; however, all ECE facilities, regardless of age, may have pipes and fixtures that contain lead (such as brass fixtures). In addition, unforeseen events (such as the one that occurred in Flint, MI, in 2014) may cause public drinking water to become contaminated with lead.

Soil:Lead can be found in soil as a result of the historic use of lead-based paint on building interiors and exteriors and leaded gasoline for cars, the current use of leaded gas by small airplanes, and industries that put lead into the environment. Soil on the property could be contaminated if the facility is next to a busy highway or high-traffic road or if it was built before 1978. In addition, if the facility is located in or near a current or former industrial area, the soil could be contaminated with lead.

Children may be exposed to lead-contaminated soil by playing in bare dirt. The main way children get lead from soil into their bodies is ingestion, most commonly by touching dirt and putting their hands in their mouths.

Consumer Products: Certain children’s products are known to have a higher risk of containing lead such as inexpensive children’s jewelry, imported pottery, antique toys, and imported toys. The use of lead in plastics has not been banned, so certain plastic toys made with vinyl/ polyvinyl chloride (PVC) [including bath books, teethers, rubber duckies, bath toys, dolls, beach balls, backpacks, pencil cases, and shower curtains] may contain lead. Lead may also be present in certain herbal remedies, folk medicines, and imported spices and foods.

COMMENTS

A state or local childhood lead poisoning prevention program, health department, and/or a certified risk assessment professional can help ECE facilities write a remediation plan to reduce any identified paint, water, or soil hazards. This plan may call for one of two types of lead hazard control work

●      Interim Controls: These are measures that minimize lead hazards and include dust removal, paint stabilization, and/or control of friction/abrasion points. These measures ensure no one is exposed to lead-based paint hazards. Some intact lead-based paint may remain in the facility if it will not pose a hazard. These controls have been found to be effective, while less expensive than full abatement.

●      Lead Abatement: These are measures that permanently remove lead-based paint and include component replacement (such as windows and windowsills), paint removal, enclosure, or encapsulation of lead-based paint. Lead abatement involves specialized techniques and must be conducted by EPA-certified lead abatement contractors.^6,7

EPA certifies lead abatement contractors to conduct either interim controls or lead abatement. These lead hazard control activities disturb lead-based paint and can create lead dust. Lead clearance testing will determine if contractors properly cleaned up after lead hazard control work and if work areas are safe for reoccupancy.⁷

For RRP work conducted independently from lead hazard control work in pre-1978 homes, EPA certifies lead-safe contractors, also known as RRP contractors. RRP contractors are trained to use lead-safe work practices when conducting tasks that may disturb lead-based paint, but they are not trained to perform lead hazard control work.

State-level programs and local funding resources may be available if financial support is needed for inspection, risk assessment, or remediation services.
