Standard Practice for Field Collection of Organic Compounds from Surfaces Using Wipe Sampling

Importancia y uso:

5.1 Wipe sampling is typically used by persons involved in hazardous waste site investigations to characterize the areal extent and the level of contamination on walls, floors, equipment, etc. Wipe sampling is also used to determine compliance with regulations.

5.2 There are many factors that contribute to variation in sampling results during wipe sampling, including the use of different pressures applied to the wipe, different kinds of wipes, different wiping patterns, the texture of the surface being wiped, and perhaps even the duration of wiping. The significance of this practice is that it standardizes wiping procedures to reduce sampling variability in the collection of samples from smooth, nonporous surfaces such as metal, glass, painted or sealed surfaces, tile, etc., in and around buildings and from pipes, tanks, decontaminated equipment, etc.
