SiREM as a Recommended Passive Sampler Laboratory

Recent guidance document recognizes SiREM as a recommended passive sampler laboratory. SiREM is a division of Geosyntec.

The Strategic Environmental Research and Development Program/Environmental Security Technology Certification Program and United States Environmental Protection Agency (U.S. EPA) Office of Research and Development recently released a draft User's Manual for Laboratory, Field, and Analytical Procedures for Using Passive Sampling in the Evaluation of Contaminated Sediments.

Within the document, SiREM's laboratory is listed as a commercial analytical laboratory capable of performing passive sampling analyses. In 2015 and early 2016, SiREM, developed the SP3TM passive sampler and interpretation service for quantification of hydrophobic organic compounds such as polychlorinated biphenyl (PCBs) and Polycyclic aromatic hydrocarbons (PAHs) in pore water, surface water, and stormwater. SP3TM has made significant advancements in the service, including additional passive sampling applications using discrete sediment samples, as well as use of visibly-detectable dyes as performance reference compounds (PRCs) making the use of PRCs less toxic and less expensive.

Currently there are several ongoing passive sampling projects for clients, who are using the data to improve site assessments and remedial feasibility studies. Passive sampling represents a dramatic improvement over traditional chemistry methods that tend to overestimate the availability and risks of these contaminant classes, and SiREM is at the forefront of this technology.
