It uses high-pressure injection of reagents into the geological subsoil, thus enabling interaction between the reagent and contaminants even in places that cannot be reached using standard injection techniques. The direct push (DP) delivery method is an effective way to deliver remediation agents to the contaminated zones. ...
Trap & Treat BOS 200 was applied at a former retail gasoline site in NYC in 2015 after In Situ Chemical Oxidation (ISCO) was attempted at the site multiple times. A No Further Action(NFA) was issued in 2018 and the property has since been converted from a vacant lot to six story mixed commercial/residential building. ...
ERDENHANCED™ (2,600 pounds) deployed in 2001 via direct-push technology (26 nodes) into two, silty-clay, laterally continuous, hydraulically conductive source zones; baseline concentration of Trichloroethylene (TCE) ≈97,400 micrograms per liter (μg/L), roughly 9% solubility of TCE, indicating significant residual source mass in ...
Among the many advantages in our range of borehole tools is that we produce versions of the Javelin and Dart that can be deployed through direct push driven casings. Vista Clara systems are the world’s only NMR logging tools that can be deployed using Direct Push technology from industry leader, Geoprobe ...
