Field Equipment Decontamination Procedures for Multi-Media Environmental Sampling Training Courses
From Environmental Sampling E-Course
During environmental sampling events, a wide variety of field equipment is used to collect samples from a multitude of media and to perform field analysis on a variety of media. It is a common practice to use most equipment on a portable basis, at more than one sampling location. This is certainly convenient, but introduces the potential for cross-contamination of sampling locations and individual samples, both of which will 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. Within this module, classroom presentations and four separate field videos discuss in detail field equipment cleaning protocols that apply to equipment used for sampling soil, ground water, surface water and sediment.

Additionally, classroom discussions cover cleaning protocols for equipment used at a variety of waste management units (e.g. landfills, surface impoundments, drums, dumpsters, waste piles) and artifacts (e.g. flooring, ceiling tile, walls). Learn how decontamination procedures may vary according to the medium being sampled and by 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.
