How GRI’s Portable SVE Systems Save Time and Money
Once soil vapor extraction (SVE) is selected as the remediation method, the default assumption for many consultants is to design and install a permanent system. That approach can work, but it is not always the most efficient or cost-effective option, especially for sites with shorter cleanup timelines or uncertain operating durations.
Learn how GRI’s portable SVE systems can significantly reduce both time and costs.
Mobilize SVE in 3 Days—Not 12 to 18 Months
Bypass BAAQMD and MBARD permit delays and up to $15,000 in fees with GRI’s pre-permitted portable SVE systems.
Cost Efficiency
| Feature | GRI Portable SVE Systems | Permanent SVE Systems |
|---|---|---|
| Permit Timeline | 3 Days with existing permits | 12 to 18 Months with BAAQMD |
| Permit Fees | Included | Up to $15,000 |
| Installation Cost | $0 (except if additional wells needed) | Average near $500,000 (2020 estimates) |
| Operational Risk | Pay only for effective run-time | Full capital loss if SVE is not effective |
| Total Cost | Less expensive if SVE needed less than 2 or 3 years | More expensive unless SVE needed for more than 3 or 4 years |
Ideal Use Cases
- Pilot Testing: Use our systems for pilot tests (including 5-day pilot tests near K-12 schools) to evaluate SVE feasibility and gather actual influent data, simplifying the permanent permitting process if you eventually need it.
- Low-Threat Closure: Perfect for fuel sites seeking closure under the Low-Threat UST Case Closure Policy. Achieve remediation to the “extent practicable” in less time than you can even permit a permanent system.
- New Construction with VIMS: Mobilize in 3 days to sites planned for redevelopment to remove contaminant mass to the “extent practicable,” as required by more agencies prior to vapor intrusion mitigation systems (VIMS).
- Pulsed Remediation: Efficiency-focused operation. We shut down for “rebound periods” to allow diffusion of contaminants from tight clays at no cost to you. We only charge when mass removal is at its peak, like only during the dry season.
- Large Sites with Multiple Plumes: Instead of miles of expensive piping, we move the system directly to the plume. One permanent system may not even be enough.
- Combined Remediation: Even if you’ve already invested in injection or excavation, GRI’s portable SVE systems are the most cost-effective way to remove remaining contaminated vapor at a fraction of the cost of a permanent system.
