ASBESTOS EPA SOIL SAMPLING

Standard operating procedures of the U.S. EPA Environmental Response Team

According to the U.S. Environmental Protection Agency (EPA), there are certain methods and problems associated with soil sampling for contaminants like asbestos and other toxins.

EPA soil sampling guidelines when asbestos is present

July 21, 2010 – Here are excerpts from a report by the U.S. EPA Environmental Response Team identifying several of its standard operating procedures for testing the toxicity of soil for asbestos (known to cause mesothelioma and asbestosis) and other cancer-causing contaminants. For details on EPA soil sampling guidelines, please visit the EPA Web site.

Method

Soil samples may be collected using a variety of methods and equipment depending on the depth of the desired sample, the type of sample required (disturbed vs. undisturbed), and the soil type. Near-surface soils may be easily sampled using a spade, trowel, and scoop. Sampling at greater depths may be performed using a hand auger, continuous flight auger, a trier, a split-spoon, or, if required, a back hoe.

Potential problems

There are two potential problems associated with soil sampling: cross contamination of samples and improper sample collection. Cross contamination problems can be eliminated or minimized through the use of dedicated sampling equipment. If this is not possible or practical, then decontamination of sampling equipment is necessary.

Improper sample collection can involve using contaminated equipment, disturbance of the matrix resulting in compaction of the sample, or inadequate homogenization of the samples where required, resulting in variable, non-representative results.

Surface soil sampling

Collection of samples from near-surface soil can be accomplished with tools, such as spades, shovels, trowels and scoops. Surface material is removed to the required depth and a stainless steel or plastic scoop is then used to collect the sample. This method can be used in most soil types but is limited to sampling at or near the ground surface.

Accurate, representative samples can be collected with this procedure depending on the care and precision demonstrated by the sample team member. A flat, pointed mason trowel to cut a block of the desired soil is helpful when undisturbed profiles are required. Tools plated with chrome or other materials should not be used. Plating is particularly common with garden implements, such as potting trowels.
