In-Situ Chemical Oxidation Services
Remington has spent a decade refining the injection of remedial materials, most notably, the injection of chemical oxidants for the remediation of petroleum and chlorinated solvents in soil and groundwater. From the early days of modified Fenton’s Reagent to the current extensive list of effective subsurface oxidizers, Remington has led the way in developing delivery methods that provide these materials to the contaminant in almost every conceivable site condition, weather condition and subsurface material.
Some significant developments include:
- Multiple Point Injection Capability
- Simultaneous Drilling and Injection at Multiple Points
- Materials Management and Incompatibility Protection
- Significantly Improved Safety
- Large Batch Injectate Mixing
- Large Injectate Capacity
- Small and Large Project Capability
- Improved Secondary Spill Containment
- Improved Internal Solution/Colloid/Slurry Mixing
- External Mixing Capacity and Zero Spill Point Transfer
It is common for us to use the same injection system with completely different injectate compositions with little turnaround time in between. It is our policy to maintain 100% material compatibility throughout this process. As such, instead of mechanically decontaminating tanks between tasks, we have designed the system for complete tank and plumbing replacement. We now maintain an inventory of identically constructed tanks, each of which is dedicated to a particular chemical solution. With the new design, all six tanks and the associated plumbing can be safely removed and replaced in a matter of minutes.
Due to the nature of our injectate solutions, it is important to adequately control any spillage that might occur for any reason. To achieve this goal, we have mounted our 2,000-gallon tank array inside a large, custom constructed, secondary containment basin. This fluid can then be recovered and injected, or treated and released. For incompatible chemical combinations, the tanks can be individually isolated via spill pallets above the secondary floor containment. Also, secondary spill containment has been developed for the external mixing facilities.
In addition, the vacuum unit is made available to quickly remove any material that may migrate to the surface via fractures, old borings or adjacent injection points. We have packer plugs with two separate designs. One is designed to plug adjacent holes or old boring points. The other is designed to plug adjacent monitoring wells when the remedial fluids enter the well with enough pressure to flow to the surface.
