ISCO Implementation
Step-by-step protocols for in-situ chemical oxidation projects from design through completion
Implementation Phases
Phase 1
Pre-Implementation Planning
- 1.Review site characterization data and conceptual site model
- 2.Conduct bench-scale treatability testing if needed
- 3.Calculate reagent demand using soil/groundwater data
- 4.Design injection grid spacing (typically 10-20 ft radius of influence)
- 5.Prepare Health & Safety Plan and Site-Specific Work Plan
- 6.Obtain necessary permits and regulatory approvals
- 7.Coordinate site access and utility clearances
- 8.Schedule pre-injection groundwater sampling
Phase 2
Field Mobilization
- 1.Mobilize direct push rig or drilling equipment
- 2.Stage reagents and mixing equipment
- 3.Establish exclusion zones and safety protocols
- 4.Conduct pre-injection site meeting
- 5.Install temporary monitoring points if needed
- 6.Set up real-time monitoring equipment
- 7.Verify injection point locations via utility clearance
Phase 3
Injection Execution
- 1.Mix reagents to specified concentrations (e.g., 40% NaMnO4, 15% persulfate)
- 2.Use direct push equipment (Geoprobe 7720DT, AMS 9600/9700 series)
- 3.Advance probe to target depth intervals (typically 2-5 ft intervals)
- 4.Inject reagent solution at controlled pressure/flow rate (<150 psi)
- 5.Monitor injection pressure and refusal conditions
- 6.Document injection volumes and depths per location
- 7.Use expendable, retractable, or sealed pressure-activated injection points
- 8.Collect soil cores for visual confirmation of reagent distribution
- 9.Measure oxidant residuals in observation wells
- 10.Real-time flow monitoring with pulsation dampeners for accurate measurement
- 11.Adjust injection parameters based on field observations
Phase 4
Post-Treatment Monitoring
- 1.Collect post-injection groundwater samples (2-4 weeks)
- 2.Analyze for target contaminants and geochemical parameters
- 3.Monitor oxidant residuals and pH
- 4.Evaluate treatment effectiveness vs. cleanup goals
- 5.Conduct quarterly monitoring for 12-24 months
- 6.Perform additional injections if needed
- 7.Prepare completion report and closure documentation
Key Implementation Parameters
- •Reagent type and concentration (e.g., 40% NaMnO4, 10-20% persulfate)
- •Injection spacing: 10-20 ft radius of influence
