Collaborative Design Support and Implementation Process
In-situ remediation requires a robust design to be successful. There are numerous factors that must be taken into account including:
- Remediation Objectives for Source and Plume
- Order of magnitude reduction expectations
- Timing
- Role of MNA in the design
- Site Characterization
- Contaminant distribution vs. lithology with a focus on sorbed mass
- High resolution profiling
- Remchlor* modeling for chlorinated hydrocarbons
- Remediation technology(s)
- Bioremediation or Chemical Oxidation
- Dosing assumptions
- Bench-Scale determination of any unique site chemistry interferences
- Contaminant contact approach
- Distribution technology
- Distribution design
- Distribution verification through pilot testing
- Remediation performance monitoring
- High resolution profiling mass reduction verification
- Post remediation groundwater monitoring to verify objectives have been met
While some consultants prefer to subcontract the total remediation design and implementation, Vironex believes that the best way to manage remediation is through a collaborative process. This maximizes the strength of the team and also reduces your risk of losing control of the project, especially in this new PRP high expectation market. (See below Vironex White Paper) Even with performance guarantees from technology vendors or applicators, most do not have the financial resources (unless they provide performance bonds and or insurance, which most can’t obtain) to stand behind projects that don’t obtain results.
SOURCE ZONE AND PLUME TREATMENT OF CHLORINATED SOLVENTS ACCEPTING THE CHALLENGE TO MEET CLIENT EXPECTATIONS MAY 28, 2011
Through a collaborative process, Vironex can support your remediation design staff with our in-house bioremediation and chemical oxidation expertise as well as in-situ soil mixing and the most extensive set of field injection experience in the industry today. This expertise, coupled with our ability to utilize high resolution profiling data sets through our S&D methodology, can support your design process to ensure a sound basis for all aspects of the remedial approach to ensure remediation objects are met.
The net result is a transparent design that is well documented with all risks quantified. This will allow for further optimization in the field to face the challenges posed by groundwater remediation, as well as providing ongoing productive communications to meet your client expectations.
* REMChlor, or Remediation Evaluation Model for Chlorinated Solvents, is an analytical solution for simulating the transient effects of ground water source and plume remediation. In the analytical method, the contaminant source model is based on a power-function relationship between source mass and source discharge, and it can consider partial source remediation at any time after the initial release.
