This guide will enable an investigator to select methods appropriate for rapid, real-time and cost effective initial determination of the nature of chemical contamination of a site. This approach facilitates a preliminary understanding of conditions potentially or actually detrimental to human health and the environment. The information which results from proper use of this guide is intended to serve as the basis for decision-making with regard to the need for further comprehensive site characterization, containment, and remedial action. This document addresses objectives of chemical field screening and selection criteria for chemical field screening methods. This guide lists a number of potential target analytes based upon respective common industrial and commercial practices. The document also references important sampling protocols, physical and chemical parameters of the site, field screening methods, and field analytical methods. This document does not elaborate on all applications or specific measurement techniques, but as an umbrella document provides references for these specific techniques and offers examples of detection principles that have been successfully used to identify analytes or groups of analytes associated with specific industrial practices. Users should consider that the suitability of a specific measurement system employing a particular method depends on the individual measurement systems precision, accuracy, detection capability, price, turn-around time, and consistency over time.
