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
