S-Micro Zero-Valent Iron Injection at LA Production Facility

Site Layout - Legacy Large Injection Trailer and Fleet Truck
Site Layout - Legacy Full-Size Injection Trailer Injection Support Truck, Generator, Forklift and Totes of S-MZVI

Working under the direction of a regional environmental consultant, the Legacy Team supported the In Situ Chemical Reduction (ISCR) groundwater treatment approach, using S-MicroZVI provided by Regenesis. This project site was located at an active manufacturing facility in Los Angeles county.

We utilized one of our full-size Injection Trailers paired with a Legacy support truck and two Track Mounted Geoprobe Direct Push Rigs. With injection points located across the site, some injection point locations were less accessible than others.

The Geoprobe 54LT worked good for some of the tighter locations that also had a lower ceiling height. The smaller 54LT Geoprobe unit was still capable of reaching the target treatment interval between 45-60 feet.

The speed, power and versatility of the Geoprobe 7822 made it perfect for this project.

The best thing about this project, is it's close proximity to a great El Salvadorian restaurant, their Pupusa's are to die for :-)


No complaints from Anthony.
