Summary
A Guide for the Technical Evaluation of Environmental Data presents the insight you need for evaluating analytical data obtained from environmental samples. Often, analyses performed on a few samples can lead to misplaced concern on the wrong analytes. For example, a geologist would know which trace metals might be naturally present in the source rock underlying a site, but not know which metals should be expected because of tire wear or which polynuclear aromatic hydrocarbons would be present because of a nearby powerplant. This book provides you with references to support decision making regarding selection of contaminants.
