Remediation System Installation Support
What is Remediation System Installation Support?
Remediation system installation support refers to the technical services, equipment, and field expertise provided to assist in the installation of environmental remediation systems. These systems are designed to remove, contain, or treat contaminants in soil, groundwater, or soil vapor at impacted sites (e.g., gas stations, industrial properties, landfills, or brownfields).
This support ensures that remediation systems are installed correctly, safely, and efficiently, in compliance with design plans and environmental regulations.
Types of Remediation Systems Supported
1. Soil Vapor Extraction (SVE) Systems
- Used to extract volatile organic compounds (VOCs) from unsaturated soils.
- Components: Extraction wells, blower units, piping, moisture separators, treatment (e.g., carbon filters).
- Support includes well installation, trenching, system layout, leak testing, and airflow balancing.
2. Pump and Treat (P&T) Systems
- Extract contaminated groundwater, treat it at the surface, then discharge or re-inject.
- Components: Extraction wells, submersible pumps, piping, tanks, filtration, and chemical treatment units.
- Support includes well development, pump setup, flow testing, and discharge line configuration.
3. Air Sparging Systems
- Inject air below the water table to volatilize and strip contaminants upward into an SVE system.
- Requires installation of air injection wells, compressors, flow meters, and check valves.
4. In-Situ Chemical Oxidation (ISCO) or Reduction (ISCR) Systems
- Deliver oxidants (e.g., permanganate, hydrogen peroxide) or reducing agents (e.g., zero-valent iron) to the subsurface.
- Support includes direct-push injection, mixing and delivery systems, pressure monitoring, and safety containment.
5. Bioremediation Systems
- Stimulate microbial activity by adding nutrients or oxygen to enhance degradation of hydrocarbons or solvents.
- Includes injection wells or infiltration galleries, mixing tanks, and nutrient delivery lines.
6. Permeable Reactive Barriers (PRBs)
- Passive systems installed in trench form, filled with reactive media (e.g., activated carbon, iron filings).
- Support may include trench excavation, media placement, hydraulic conductivity testing.
Purpose of Remediation System Installation Support
| Objective | Description |
| Ensure proper system setup | Verify that components are installed per engineering specifications |
| Maintain regulatory compliance | Meet environmental laws and cleanup criteria (e.g., EPA, provincial guidelines) |
| Minimize operational risks | Avoid leaks, electrical faults, or system inefficiencies |
| Facilitate long-term system performance | Support proper function for active remediation and long-term monitoring |
Equipment Typically Installed
- Blowers and compressors
- Submersible pumps
- Air/water separator tanks
- Carbon vessels or air strippers
- Chemical feed tanks
- Process control panels (PLC/SCADA)
- Trenched or aboveground piping
- Groundwater monitoring and sampling ports
Health, Safety, and Environmental Considerations
- Hazardous materials handling (permits, storage, PPE)
- Air emission controls (e.g., vapor treatment or catalytic oxidation)
- Secondary containment (for tanks and chemical systems)
- Noise and vapor control (in populated areas)
- Confined space protocols (for underground installations)
