Abstract
Contaminant concentrations in groundwater are typically analyzed using traditional laboratory analytical procedures approved by the Environmental Protection Agency (EPA) or state regulatory agencies. The use of off-site laboratories provides very high-quality water quality data at a relatively high cost in terms of time and money. Yet there are many instances when it is desirable to have water quality data measured in the field. The field methods for measuring water quality typically cost much less than the corresponding laboratory methods. However, the usability of the field data may be uncertain when the results are qualitatively compared to duplicate laboratory results. Groundwater samples collected during a groundwater circulation well pilot study were analyzed using field kits to measure concentrations of trichloroethylene (TCE) and the explosive compound known as RDX. A subset of the samples was split for duplicate laboratory analysis. Linear regression analysis and relative percent difference analysis were performed on the duplicate results to evaluate the comparability of the field and laboratory data. The data analyses were also used to evaluate the concept that the field kits were more accurate for specific concentration ranges, as well as the concept the field kit results would improve as field personnel gained experience with the field analysis procedures. © 2002 Wiley Periodicals, Inc.
