... Environmental investigations typically entail broad data gathering efforts which include field screening surveys and laboratory analyses. Although usually collected extensively, data from field screening surveys are rarely used in the actual delineation of media contamination. On the other hand...

... and source of contamination. Sample collection methods for this step should be nonintrusive or minimally intrusive; few permanent monitoring devices should be installed; and field screening analytical methods should be emphasized. The resulting data are used to assess the potential for risk to human health...
