This technical bulletin explains how colloidal activated carbon injection combines rapid contaminant adsorption with biodegradation to treat chlorinated solvents and petroleum hydrocarbons. It shows how molecular biological tools such as QuantArray®‑Chlor, QuantArray®‑Petro, and CENSUS® qPCR are critical for pre‑injection design, evaluating bioaugmentation needs, and monitoring long‑term remedy performance.
This technical bulletin explores the microbial potential for biodegradation of pesticide‑contaminated sites, including organochlorine, organophosphate, and nitrogen‑based pesticides. It highlights how next‑generation DNA sequencing (NGS) can identify pesticide‑degrading bacteria and fungi to support bioremediation assessment and site management decisions.
This technical bulletin explains how molecular biological tools (MBTs) such as QuantArray®‑Chlor, QuantArray®‑Petro, and CENSUS® qPCR are used alongside in situ thermal remediation to evaluate biodegradation before, during, and after heating. It demonstrates how integrating microbiological data with thermal treatment supports effective transitions to bioremediation, bio‑polishing, and monitored natural attenuation (MNA).
This technical bulletin examines the ability of cold‑adapted (psychrophilic) microorganisms to biodegrade petroleum hydrocarbons in cold and permafrost environments. It highlights how molecular tools such as QuantArray®‑Petro can identify and quantify key biodegradation pathways to support bioremediation decisions at low‑temperature sites.
This technical bulletin explains how to design, implement, and evaluate electron donor addition to enhance anaerobic bioremediation at chlorinated solvent sites. It highlights how molecular biological tools such as CENSUS® qPCR, QuantArray®‑Chlor, and in situ microcosms are used to determine bioaugmentation needs, optimize biostimulation, and verify remedy performance over time.
Bio-Traps® are innovative passive samplers that reveal which microbes are truly active and driving biodegradation at contaminated sites. This paper explains how Bio-Traps® help practitioners confidently evaluate natural attenuation, assess remediation performance, and make better site-management decisions.
This product brochure provides an overview of Bio-Traps®, which are passive microbial samplers that collect microbes over time for a better understanding of biodegradation potential. Bio-Traps® can be analyzed using a variety of molecular biological tools, including CENSUS® qPCR, QuantArray®, and Next Generation Sequencing.
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.
