ACTIVE REFINERY PROCESS UNIT PROPOSED LOCATION
ENTACT performed soil remediation and ground improvement efforts to address low-pH soils resulting from a sulfuric acid spill at the refinery. Stabilization of the ground was essential to support the construction of a new process unit at the site. These remediation efforts were crucial for ensuring the structural integrity needed for the upcoming development at the refinery. On this project, ENTACT: Performed in-situ solidification on 86,000 cubic yards of material Enhanced soil strength using a blend of granulated ground blast
BROWNFIELD REDEVELOPMENT AREA REMEDIATION
ENTACT performed remediation activities across several blocks and lots as part of a larger brownfield redevelopment project aimed at future residential use. The site was impacted by multiple industrial operations, leading to soil contamination with various hazardous substances, including polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), polychlorinated biphenyls (PCBs), hexavalent chromium, chromium ore process residue (COPR), extractable petroleum hydrocarbons (EPH), pesticides, metals, and lead. For this project, ENTACT: Designed, procured, and installed a 1,600-linear-foot, 40-foot-deep permanent vertical hydraulic control
ACTIVE REFINERY TANK FOOTPRINT SUBSURFACE GROUND IMPROVEMENT
As part of a larger capital program, an active refinery aimed to expand its footprint for 14 tanks and four pump pads. Before construction could begin, ENTACT performed subsurface soil treatment to address soft saturated soils, reducing potential settlement of the new structures. This comprehensive ground improvement approach ensured the structural integrity of the new tank foundations and pump pads, meeting project objectives and performance criteria. On this project, ENTACT: Installed a series of eight-foot diameter soil-cement columns on a
LOGISTICS PARK DEVELOPMENT
ENTACT completed comprehensive soil and groundwater remediation activities at a former coal-fired power generating station contaminated with polychlorinated biphenyls (PCBs), hexavalent chromium (Cr(VI)), chromium ore process residue (COPR), and extractable petroleum hydrocarbons (EPH). These contaminants were present at levels exceeding cleanup criteria, necessitating remediation for future site development. Throughout this project, ENTACT: Excavated, segregated, and characterized hazardous (TSCA and RCRA) and non-hazardous soil for off-site treatment and disposal Installed 7,500 square feet of a steel sheet pile cutoff wall using
