A Quick Guide To Sampling And Testing For Lead Abatement

Recognizing the presence of lead in properties is often not an easy process. This includes taking samples from different areas of the property and sending them to a certified laboratory for lead analysis and testing.

There are three sampling techniques generally used to estimate the amount of lead in a building prior to carrying out a lead reduction activity. The lead reducing agent such as sandowconstruction.com collects samples according to the guidelines set by the EPA. Soil is the first area where lead can be found.

Dust Sampling:

Dust particles can carry large amounts of lead when circulating on the property. Dust samples can not only detect lead contamination but are also used in lead reduction activities. Dust sampling can be used to ensure that the removal of lead has been successful from the area. Dust samples can only be collected from smooth, hard, and pore-free surfaces.

Soil Sampling:

Due to the force of gravity, lead particles that fall from emission sources such as exhaust gases, industrial plants, and even released lead paint are carried to the earth. Years of sedimentation can be deposited in the soil, especially near roads or production areas. As part of the pre-test activities to reduce lead, soil samples were obtained using deboning or calculation methods. Half an inch of soil is collected from above. 

A Sampling Of Chips With Paint:

By sampling paint flakes, the presence of lead in the paint can be measured. Color chips are collected directly from the surface of the sample or by a portable XRF tool that is able to examine and measure the lead level on the target area.

Lead reduction activities should always begin with a sampling of all possible sources of lead contamination. After the process is complete, the lead reduction process can be continued with a better understanding of the level of lead contamination.
