On July 9, 1991, five panel members representing several sectors of the environmental analysis industry convened in Washington, DC, at the invitation of the University of Findlay, Wheaton Scientific, I-Chem Research and VWR Scientific. The objectives of the discussion were: 1) to increase awareness of sampling variability in environmental measurements, and 2) to suggest approaches to deal with sampling variability. (The meeting discussion was published as two separate articles, both of which are included in the PDF file.)
