ENTACT implemented in-situ solidification and stabilization at this former manufactured gas plant (MGP) to address impacted materials and prepare the site for redevelopment. Through two phases of work, we effectively managed environmental conditions while meeting our Client’s schedule and budget objectives. Upon project completion, ENTACT had:

• Demolished and removed existing structures, with off-site disposal and recycling of building slabs and subsurface materials
• Collected, managed, treated, and discharged MGP contact water
• Removed, reinstalled, or protected utilities and plugged and grouted abandoned pipes
• Excavated and disposed of more than 25,000 tons of MGP-impacted soils
• Performed in-situ solidification and stabilization of 58,000 cubic yards of MGP-impacted
• Managed more than 10,000 cubic yards of swell through immediate in-place grading or reconditioning and placed within a former building footprint

Sustainable Remediation

• Utilized 700 tons of recycled concrete as fill material for backfilling
• Crushed and reused asphalt removed during site preparation
• Recycled 108 tons of steel recovered from the demolition of structures
• Reused 9,000 gallons of MGP contact water for onsite activities
