Incremental Sampling Methodology

Wednesday, June 22nd, 2011

MIS2Incremental Sampling Methodology (ISM) is a technique designed to statistically reduce or limit variability associated with discrete sampling. It provides unbiased, representative and reproducible estimates of the mean concentration of analytes in a specific area of interest, called a “decision unit.”

Interest in (ISM) has grown in recent years largely because the approach, when applied correctly, can significantly reduce sampling uncertainty. This in turn can increase the probability that sample data is more representative of average site conditions at hazardous waste sites, thereby strengthening decision making at the site.
