Alkaline Activated Sodium Persulfate Well Injection

Updated: Oct 10


We are happy to share our latest win in environmental groundwater remediation. Our team partnered with a local engineering firm and tackled this project at an active service station in Los Angeles County.


We injected Klozur Sodium Persulfate activated with 25% Sodium Hydroxide liquid.


This proven In-situ chemical oxidation (ISCO) technology is commonly utilized to treat petroleum hydrocarbon contaminated groundwater.




The Klozur Sodium Persulfate was deliverd in 55.1 lb bags, and was provided by Evonik.








The 25% Sodium Hydroxide liquid was delivered in 330 gallon totes, and was provided by Brenntag.






Per request, daily hazmat deliveries of the reagents were coordinated by Legacy to avoid any overnight onsite storage of oxidizer and activator.




Our Mix Water came from a nearby fire hydrant, Legacy coordinated the installation of a construction meter with the Los Angeles Department of Water & Power.







We utilized one of our state-of-the-art trailer-mounted injection rigs for this project.


The Klozur Sodium Persulfate was weighed to support the batch mixing.






The Klozur Sodium Persulfate and 25% Sodium Hydroxide liquid was mixed in alternating batches in our 150 gallon mix tanks.








Connection to the Injection Wells was done using our standard Well Head adapters.







Since we were working at an active facility, multi-channel hose cross-over ramps were utilized on our runs to the Injection Wells.




Hose ramps were also used across the service station entrances for the mix water supply.


These cross-over ramps improve safety and help minimize the disruption and impact to the tenant and their customers.



This project showcases our commitment to safety, quality and performance. We’re proud to have completed another successful remediation project, and we look forward to continuing our mission to protect the environment and public health.
