Field Equipment Decontamination Procedures Training Courses



It is a common practice to use a variety of field equipment that travels from well to well during a ground-water sampling event. Portable equipment such as water-level gauges, flow cells, analytical instruments and multi-parameter sondes are examples of some equipment that is used in each monitoring well, even in situations where dedicated pumps are used. And, of course, where portable pumps are used, the pump (and, in many cases, the discharge tubing) will also travel from well to well. To avoid the potentially very serious and costly problem of monitoring well cross-contamination, it is critical to implement thorough and effective field equipment cleaning protocols.
