14C Assays, Min-Traps, and Sampling Guidance: Documenting Abiotic Degradation of Contaminants

Abiotic degradation of groundwater contaminants such as chlorinated ethenes and 1,4-dioxane has been historically under-considered during remediation strategy selection. Despite its usefulness in aerobic aquifers, where reductive dechlorination of contaminants is inhibited, these processes have been difficult to document conclusively.  The lack of readily identifiable transformation products from 1,4-dioxane makes documenting its degradation at low…

Development of Molecular Biomarkers for Monitoring and Mitigation of Microbial Corrosion

Microbially influenced corrosion (MIC) is a widespread and costly challenge across many industries. In most cases, MIC is driven by complex, multispecies biofilms with diverse metabolic activities. While some biofilms are non-corrosive, others can cause severe damage to steel and related infrastructure. Distinguishing corrosive from non-corrosive microorganisms remains difficult with current methods, and MIC diagnosis…
