Tech Bulletin – Choosing Matrix DHC

Summary:

This technical bulletin explains how selecting the appropriate sampling matrix—groundwater, sediments, or Bio‑Trap® samplers—affects the interpretation of Dehalococcoides (DHC) and functional gene data for evaluating in situ reductive dechlorination. It provides practical guidance on using CENSUS® qPCR and QuantArray®‑Chlor results to support site assessment, remedy selection, and performance monitoring at chlorinated solvent sites.
