Guide to Collecting a Proper Soil Sample

Use of proper sampling methods is vital to obtain representative samples of soil waste to accurately characterize (hazardous or non-hazardous) your stabilized waste piles. If improperly conducted, valuable time and resources may be wasted by contractors, generators and consultants. (View video below for proper sampling methods)

EPA manual SW-846 and ASTM* standard D75 address proper ways of conducting sampling activities to produce a representative sample. For a given project, several smaller samples should be randomly pulled from various areas of the waste pile; this includes top-to-bottom level sampling. (We suggest eight (8) to ten (10) samples). It is important to dig down into the soil waste with a tool, such as a small garden hand shovel or a core sampler, and obtain samples.

Combined the samples into a larger pile and split with a shovel into four sections.You should obtain four (4) large samples of at least 500 grams. The required number of samples to collect & test is typically determined by the project work plan, or State and local regulations. Samples sent to lab should be approximately 250 grams each, or a one quart baggie filled one-half full.
