Soil sampling equipment falls into one of two categories – equipment that is manually operated and equipment that is deployed using a portable drive source, or a direct-push or drilling rig. Most soil sampling equipment is designed and built to be reused, so it is a common practice to deploy the same soil sampling equipment at multiple sampling locations. This is certainly convenient, but introduces the potential for cross-contamination of sampling locations and individual samples, both of which may affect the representative nature of samples collected. To prevent this potentially very serious and costly problem, it is critical to implement thorough and effective field equipment cleaning protocols. This module discusses in detail field equipment cleaning protocols that apply to equipment used for sampling soil, both sample-contacting equipment and equipment that facilitates sample collection but doesn’t contact the sample. Learn how decontamination procedures may vary according to the sampling equipment being used and by the contaminants being analyzed in samples. Discover why a few of the “detergents” commonly used for field equipment cleaning should be avoided for some field applications because they may contain phosphates, and why others may introduce trace amounts of semi-volatile compounds if not diluted sufficiently. You will also learn important terminology such as the differences between portable, dedicated, designated and disposable field equipment.
