Topic: Planning and Executing a Successful Ground-Water Sampling Event

The ground-water monitoring wells are installed and developed and you are finally ready to sample!  Or are you?  This module discusses in great detail all of the issues that need to be considered and documents that need to be in place prior to setting out to collect ground-water samples.  Learn why it is critical to prepare and follow a written, site-specific Sampling and Analysis Plan.  If you are an emergency response team member or regulatory enforcement staff, learn what alternative approach you would need to take to conduct a sampling event.  Learn why you need to understand the terms accuracy, precision, bias and defensibility.  Field videos are included within this module to explain well inspection and good housekeeping practices that should be employed during a ground-water sampling event.

Topic: Field Equipment Decontamination Procedures

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.  This module discusses in detail field equipment cleaning protocols that apply to drilling, soil sampling and ground-water sampling field equipment.  Learn 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.  Field videos are included within this module to explain the practices and procedures used in decontamination of field equipment used in ground-water sampling events.
