The Michigan Department of Environmental Quality (MDEQ) Remediation and Redevelopment Division (RRD) announces the availability of the Incremental Sampling Methodology and Applications Resource Materials, dated January 2018.  Incremental Sampling (IS) is a combined field sampling and laboratory sample processing protocol designed to provide a reproducible, unbiased, statistically valid estimate of the mean contaminant concentration within a pre-defined volume of media. 

 IS methodology may be used at sites of environmental contamination alone or in combination with other sampling protocols.  For purposes of these resource materials, IS applies to the evaluation of contaminant concentrations in solid materials including soils, fill, waste piles and sediments within a horizontally and vertically defined volume when implemented along with a data quality objectives (DQOs) process.  Using these parameters, IS methodology produces data that may be more representative than those achieved using more traditional sampling practices, such as discrete sampling.  The MDEQ has successfully applied IS methodology to determine representative concentrations of organic and inorganic contaminants in solid media and have utilized IS methodology to select effective remedial actions.

The IS Resource Materials describes, in general terms: IS sampling concepts, systematic planning and DQOs, decision unit designation and sampling design, field implementation, laboratory processing and analysis, and RRD program applications.

For questions regarding IS methodology, please contact John Bradley, MDEQ, RRD/Superfund at (517) 284-5069, or bradleyj1@michigan.gov.
