Field-scale remediation of a metolachlor-contaminated spill site using zerovalent iron.
Pesticide spills are common occurrences at agricultural cooperatives and farmsteads. When inadvertent spills occur, chemicals normally beneficial can become point sources of ground and surface water contamination. We report results from a field trial where approximately 765 m3 of soil from a metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide] spill site was t...
متن کاملPilot-scale treatment of RDX-contaminated soil with zerovalent iron.
Soils in Technical Area 16 at Los Alamos National Laboratory (LANL) are severely contaminated from past explosives testing and research. Our objective was to conduct laboratory and pilot-scale experiments to determine if zerovalent iron (Fe(0)) could effectively transform RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) in two LANL soils that differed in physicochemical properties (Soils A and B)....
متن کاملMagnetic characterization and interaction modeling of zerovalent iron nanoparticles for the remediation of contaminated aquifers.
Nanoscale zerovalent iron (NZVI), promising for in situ degradation of many environmental contaminants, has been shown to aggregate reducing reactivity and mobility. Aggregation is attributed to the magnetic attractive forces between particles. In this study an alternating gradient force magnetometer (AGFM) is used to measure magnetic properties of NZVI. The magnetization curve is modeled accor...
متن کاملRemediating dicamba-contaminated water with zerovalent iron.
Dicamba (3,6-dichloro-2-methoxybenzoicacid) is a highly mobile pre- and post-emergence herbicide that has been detected in ground water. We determined the potential of zerovalent iron (Fe0) to remediate water contaminated with dicamba and its common biological degradation product, 3,6-dichlorosalicylic acid (DCSA). Mixing an aqueous solution of 100 microM dicamba with 1.5% Fe0 (w/v) resulted in...
متن کاملBioremediation of a Drilling Waste-Contaminated Soil; Biotreatability Assessment and Microcosm Optimization for Developing a Field-Scale Remediation Process
Background: Petroleum drilling and exploration operations generate a significant amount of oily wastes. Comparing with physical and chemical remediation methods, bioremediation is cost-effective, highly efficient, and environment-friendly technology.Objectives: The aim of this study was to evaluate biological treatment efficiency for an oil-contaminated s...
