Acetochlor (56 µg/L) and Metolachlor (6,300 µg/L) contaminated groundwater across an 11,400 ft² remedial footprint at a former agricultural chemical storage facility. Complex layered geology—fill, sandy silt, and silty clay—required a treatment distribution strategy capable of achieving contact across all three soil units.
BAM was distributed through 120 DPT injection points designed to ensure even treatment chemistry coverage across the full 11,400 ft² footprint. Five extraction wells with vacuum truck support were operated to control the hydraulic gradient and enhance treatment chemistry distribution within the heterogeneous subsurface.
Post-treatment sampling confirmed 90.9% acetochlor reduction and 85.5% metolachlor reduction across the 11,400 ft² remedial footprint at the former agricultural chemical storage facility. BAM treatment chemistry was distributed through 120 DPT injection points, achieving contact across all three subsurface soil units—fill, sandy silt, and silty clay. Five vacuum extraction wells operating simultaneously with injection maintained hydraulic control and enhanced treatment chemistry distribution within the layered geological setting. Results demonstrated BAM’s effectiveness against agricultural herbicide compounds, including acetochlor at 56 µg/L and metolachlor at 6,300 µg/L, in a complex multi-layer subsurface environment.
