ISM Case Studies - Using Project Objective to Select Laboratory Processing Options

Tuesday, May 19, 2015 - 1:30 P.M. Eastern

About this webinar:

The overall goal of the Incremental Sampling Methodologies (ISM)* laboratory processing is to produce an appropriately sized subsample that has the analytes of interest at the same concentration as the large incremental sample collected in the field. The end goal is to produce results that represent the conditions at the site and facilitate good decisions. 

To achieve this goal, improvements in laboratory sample processing and subsampling are needed. Typical processing options cover management of soil moisture, disaggregation, milling, sieving, sample splitting and subsampling. Each of these lab processes has potential impacts on data quality and representativeness. 

There are several laboratory sample processing choices that must be based on the specific project objectives to yield data that is usable for future site decisions. We will look at a few example case studies on how the project objectives will dictate choosing specific laboratory processing options. The types of sites include military training ranges, urban gardens, underground storage tanks, and skeet shooting ranges. Analytes include explosives, metals, PAHs, VOCs and PCBs.

Topics the presentation will cover:

  • Data Quality Objectives Related to ISM
  • Soil Moisture Management
  • Disaggregation, Sieving, Milling and Subsampling
  • ISM Case Studies

Who should attend?

  • Consultants
  • Regulatory Officials
  • Federal Government Officials (i.e. - USACE, etc.)
  • Site Owners

A question and answer session will immediately follow the presentation. At the conclusion of each webinar, you will be asked for your feedback and opinions for future webinar topics to be developed by TestAmerica.

*  The Interstate Technology and Regulatory Council (ITRC) team on Incremental Sampling Methodology (ISM) worked for three years to assemble guidance to improve the quality of site characterization. The ITRC ISM guidance document was publically released in February 2012 with Internet based training each quarter since then. (See http://www.itrcweb.org/ISM-1)
