A closer look at the projects we’ve helped bring from plan to completion.
A release occurred on this property that was discovered to be multiple comingled plumes covering four city blocks.
A significant release was discovered at this property, revealing multiple comingled plumes that extended across four city blocks. The scope of the impact required a targeted remediation approach using Air Sparge (AS) and Soil Vapor Extraction (SVE) systems to address subsurface petroleum contamination.
This project focused on managing the conditions of the release and implementing the necessary remediation steps to move the site toward environmental compliance.
We performed an electrical resistivity survey to map subsurface conditions and pinpoint two comingled plumes without unnecessary drilling.
At this site, we were brought in to evaluate a large hydrocarbon release that ultimately turned out to be two comingled plumes spanning roughly four city blocks. Before committing to widespread drilling, we needed a clearer picture of what was happening underground.
We performed an electrical resistivity survey to map subsurface conditions and guide our next steps. We drove a series of rods into the ground, connected them to our equipment, and sent electrical pulses at different depths and distances. Those readings allowed us to build a geologic model showing the resistive and conductive zones beneath the site.
With that model in hand — and supported by targeted confirmation wells — we were able to pinpoint the true extent of contamination and identify the overlapping plumes driving the size of the impacted area. Using resistivity early in the process helped us reduce unnecessary drilling, focus our assessment work, and establish accurate targets for remediation.
We completed targeted direct-push bioremediation injections using our Geoprobe and custom-mixed amendments to treat the dissolved-phase plume.
At this site, we used our Geoprobe and injection tooling to perform a series of direct-push bioremediation injections. Before treating the plume, we sampled groundwater across the area to understand site conditions — pH, temperature, and the overall environment the microbes were working in.
Once we had that data, we coordinated with a chemical manufacturer to select the right bioremediation amendment. We mixed the amendment on-site in our injection rig and then used the Geoprobe to inject it at multiple points throughout the dissolved-phase plume.
The amendment feeds the existing microbial population and accelerates the breakdown of remaining contaminants. By targeting the injections directly into the impacted zone, we were able to treat the dissolved-phase product efficiently and set the site up for measurable reduction over the coming monitoring events.
