It is very important to have an assistant help collect the sample to reduce the risk of crosscontamination. Before you begin, make sure that you identify who will sample the surface and who will assist. The assistant will handle all of the sampling supplies and never touch the surface to be sampled. The sampler will touch the supplies only as the assistant hands them over. Publication date from document properties. 508version_spongesamplingjobaidfinal_09.30.2014.pdf
