Incremental Sampling Methodology [ISM]

Eurofins TestAmerica’s Incremental Sampling Methodology Support    

Incremental Sampling Methodology (ISM), also referred to as Multi-Incremental SamplingTM (MIS) and Incremental Composite Sampling (ICS), is a structured composite sampling and processing protocol having specific elements designed to reduce data variability and increase sampling representativeness for a specific volume of soil under investigation.  The use of ISM requires the development of a well-conceived sampling plan developed by the entire investigative team, which consists of consultants, regulators, geologists, analytical chemists, and risk assessors.  Eurofins TestAmerica supports ISM for site characterizations so our clients can sample with a plan, process samples with a purpose and make site decisions with confidence. Eurofins TestAmerica offers a wide variety of options for projects requiring ISM support, including multiple sample processing options to support the project defined goals. We follow EPA, ASTM, Standard Methods and other approved methods for ISM support.

How Can Eurofins TestAmerica Help You With ISM Sampling?

Since 2003, Eurofins TestAmerica has been at the forefront of the evaluation and implementation of ISM at our laboratories.  Starting in 2009, Eurofins TestAmerica actively participated with the Interstate Technology and Regulatory Counsel (ITRC) in the development of its ISM technical and regulatory guidance, and continues as one of the ITRC ISM trainers. Eurofins TestAmerica has designed its ISM services as a turnkey solution for our clients to provide a single source solution for ISM and analytical support.  We offer detailed, technical support to the investigative team in the evaluation of ISM options, comprehensive ISM sample processing, and comprehensive organic and inorganic laboratory testing services.
