Environmental Remediation & Construction

Environmental Remediation & Construction Southern Crop Services, Environmental and Remedial Construction Services – Aerostar SES provided environmental and remedial construction services at the Southern Crop Services State Hazardous Waste Site located in Delray Beach, Florida. The Southern Crop Services site consisted of a former air strip occupying approximately 32 acres which was operated from the late 1940s until 1992. The Southern Crop Services site served as a base of operations for the aerial application of agricultural chemicals. Aerostar SES provided labor, equipment, lower-tier subcontractors, materials, and supplies needed to remove approximately 14,000 tons of pesticide and heavy metals impacted soils. A portion of the excavation area was covered in thick forested land. Aerostar SES obtained the appropriate permits and coordinated the removal and recycling of the trees with a local mulch manufacturing facility at minimal costs to the client. Prior to and during construction activities, Aerostar SES procured and maintained a stormwater management plan from the FDEP.
Environmental Remediation & Construction Florida Department of Environmental Protection, Remedial Action Source Removal and Dewatering Aerostar SES performed source removal activities including removal of Liquid Phase Hydrocarbons (LPHs) from the water table and excavation of impacted soils at a bulk AST facility for the FDEP. The project included excavating hydrocarbon impacted soils to approximately ten feet below land surface. Approximately 8,800 tons of hydrocarbon-impacted soil were excavated and transported to a state-approved landfill. Approximately 400 trucks were required to transport the impacted soil off-site. Aerostar SES also operated a dewatering system in order to reach the specified depths of the excavation. A water treatment system was installed to treat groundwater to National Pollutant Discharge Elimination Systems (NPDES) discharge standards. Approximately 17,000,000 gallons of treated groundwater were discharged to the St. Johns River. Following the excavation of hydrocarbon impacted soils, Aerostar SES installed 12-inch diameter LPH recovery wells. During the following year, LPH was removed from the wells using a vacuum truck until no LPH remained at the site. The site was subsequently removed from FDEP’s list of Imminent Threat Sites.
