Remediation Technologies

This category includes technical resources related to enhanced anaerobic oxidative bioremediation, where electron acceptors and nutrient amendments are used to stimulate anaerobic microbial oxidation of organic contaminants in soil and groundwater. Documents focus on treatment mechanisms, amendment selection, design considerations, and application of nitrate-, sulfate-, and metal-reducing processes to support effective and sustained contaminant degradation.

This category includes technical resources related to anaerobic reductive bioremediation, where electron donors and nutrient amendments are used to stimulate anaerobic microbial reduction of chlorinated solvents and other reducible contaminants in soil and groundwater. Documents focus on reductive dechlorination mechanisms, amendment selection, treatment design considerations, performance monitoring, and integration with complementary remediation technologies for both source and plume applications.

This category includes technical resources related to In Situ Chemical Reduction  (ISCR) technologies used to remediate chlorinated solvents and other reducible contaminants in groundwater and soil. Documents focus on abiotic reduction mechanisms, treatment design considerations, reagent selection, delivery methods, and integration with biological processes to achieve effective and durable remediation outcomes.

This category includes technical resources related to in situ sorption and biodegradation technologies that combine contaminant sequestration with enhanced biological treatment in soil and groundwater. Documents focus on the use of sorptive media (e.g., activated carbon) in conjunction with aerobic or anaerobic biostimulation to rapidly reduce dissolved-phase concentrations, limit plume migration, and support sustained biodegradation of petroleum hydrocarbons and other organic contaminants.

This category includes technical resources related to surfactant-enhanced aquifer remediation (SEAR), where engineered surfactant formulations are used to reduce interfacial tension and mobilize non-aqueous phase liquids (NAPL) in soil and groundwater. Documents focus on treatment mechanisms, surfactant selection, microemulsion behavior, recovery strategies, and integration with complementary remediation technologies across source and plume settings.
