Specifically, a novel delivery system, utilizing direct push advancement equipment coupled with high-pressure air and liquid systems allowed for uniform lateral distribution of the materials to the impacted capillary fringe zone. The
treatment zone has extended from 9 to 11 feet below grade across the 20,000 square foot property. Preliminary analytical results from soils and groundwater at the site indicate that the targeted 18-month remediation time-line will be met.
Samples from the groundwater and the soils 300 days into the eighteen-month program indicate total BTEX concentrations in the soils have been reduced an average of 76% with a 92% decrease in toluene. Groundwater BTEX levels have also seen a dramatic decrease, approaching targeted treatment levels in several of the wells within ten months.
