This service is different from a lead-based paint survey in that it attempts to measure the potential lead exposure hazards inside the home as opposed to simply identifying the presence or absence of lead-based paint. The presence of lead-based paint by itself does not necessarily mean it will result in a lead exposure. Lead exposures in children are primarily associated with ingestion of lead in the form of dust, paint chips or by lead contaminated items such as food or toys.
Lead exposures can come from a number of items not typically included in most lead-based paint surveys including leaded weights inside older style windows, lead fixtures and simple dust brought into the home some time previously. This screen includes the collection of surface wipe samples from inside surfaces in the home to determine the presence of elevated lead levels inside the home.
Also, in addition to sampling inside the home, this screening service includes soil sampling that can provide valuable information about possible lead exposure risk outside the home. Soil sampling around the home can provide information about exterior lead-based paint or lead building materials that may be deteriorating resulting in lead contamination of the soil. Areas where children will play or where vegetable gardens may be planted can be tested to help avoid lead exposure through their use.
Service includes collection of two composite wipe samples inside the living spaces, one sample a composite of different interior floor surfaces, the other a composite of different window sill surfaces. Service also includes collection of two composite soil samples, one sample collected along drip line of exterior of the building on all four sides and one sample a composite of locations on the property believed to have the potential for child play areas or gardening.
The lead hazard screen is performed in general accordance to requirements established in Colorado Regulation 19 – The Control of Lead Hazards. All sampling and assessments are performed by a Colorado certified lead inspector and lead risk assessor as defined by Colorado Regulation 19, Part A.
The intent and focus of this service is for informative purposes only and not to be used for regulatory compliance or legal purposes. If the client of this service requests services for regulatory or legal purposes a separate contract for those services is required.
A lead hazard screen is a limited risk assessment that checks for the presence of lead dust in the home and lead in the soil around the home. It is different from a lead-based paint survey in that it checks for an existing lead hazard as opposed to simply the presence of lead-based paint.
What value does it give? A lead hazard screen can make you aware if there is an existing risk of lead exposure inside the home. This is particularly helpful if small children will be living there since they are most at risk of lead-poisoning from the presence of lead dust.
Is there lead in this house? Without a full lead survey of the home we cannot say for sure, however lead-based paint and other lead containing objects were common in some homes built prior to 1978. The lead hazard screen is a quick and affordable way to check if there is lead dust in the home or lead contamination of the soil.
What is included in the lead hazard screen? The screen includes collection of surface wipes samples inside the home and soil samples from around the home. The surface wipe samples are taken on the floors and window sills of the home to check for lead dust. The soil samples are taken from the drip line around the home to check for lead runoff and from areas that have the appearance that they may either be child play areas or locations where gardens may be planted.
Will this show that the home has no lead problems? This screen only checks for an immediate lead hazard. Lead-based paint or lead containing objects could still be in the home. However, if these materials are in good condition and not being damaged they are less likely to release lead dust that could cause a lead problem. This screen looks for lead dust and lead contamination in soil which are signs that there may be a history of damaged lead materials in the home.
So this shows if there is damaged lead in the home? No, this screen looks for the potential hazards that can arise from damaged or worn lead-containing materials. The presence of lead dust or lead-contaminated soil both present possible routes of exposure to lead, whether it is lead dust getting on hands or in food, or lead soil getting on hands or into plants grown in the soil.
