O&M of Remedial Systems

Remedial systems need to be tested, managed, and maintained to optimize performance. After a system is designed, PWT conducts bench-scale testing, computer modeling, and field demonstrations to evaluate innovative technologies. Once a system is built, PWT operates and provides oversight and long-term monitoring for everything from containment structures such as landfill covers, to groundwater remediation systems, to a wide variety of innovative technologies.

  • RCRA-equivalent covers
  • Hazardous waste landfills
  • Industrial wastewater pretreatment
  • Treatment technologies
    • In-situ and ex-situ bioremediation and oxidation
    • Biointrusion and capillary barriers
    • Soil-vapor extraction
    • Soil washing
    • Cut-off walls
    • Monitored natural attenuation
  • Green and sustainable initiatives

“PWT compiled a phenomenal team of experts from various disciplines to produce and approved design for a RCRA Subtitle C Equivalent Land Cover. This cover will be a template for remaining land covers at the Rocky Mountain Arsenal Site and will be closely monitored by other sites throughout the United States as the standard for achieving ad RCRA-equivalent land cover…”  EPA Performance Evaluation Report

Civil & Geotechnical Engineering

Civil Engineering. PWT develops solutions on all phases of project development, from pre-design feasibility studies through design, construction management, and preparation of as-built reports. Our engineers are licensed to practice in several states and can turn complex site conditions into optimal solutions.

  • Feasibility studies / engineering evaluations
  • Engineered remedial designs (hazardous waste disposal, RCRA-equivalent covers)
  • Remedial system optimization
  • Groundwater remediation systems
  • Soil remediation systems
  • Water-supply development
  • Computer simulation and design of water distribution systems
  • Design of roadways, pavement systems, and bridges
  • Grading plan design
  • Design of wastewater treatment and collection systems

Geotechnical Engineering. PWT evaluates subsurface soil conditions, designs cost-effective solutions to subsurface constraints, and defines the long-term performance of foundations and earthen structures to enhance the planning, design, and construction of buildings, process facilities, roads, pipelines, dams, landfills, and other structures.

  • Foundation and slope-stability investigations
  • Settlement evaluations
  • Design of mitigation plans
  • Borrow-source delineation
  • Design of foundations and dams
  • Construction management and inspection
