A New Year and a New Series of Posts on the Subsurface Injection of In Situ Remedial Reagents
This is the first in a series of blog posts on an in situ remediation document that was released a few years ago. This document is full of technical gems; unfortunately it does not get much discussion nor is it referenced very often. The limited awareness of this document may be due in part to its: A) location, this document is buried deep in the LARWCB’s website and B) its title, which is quite lengthy and not very catchy. The Report is entitled “The Technical Report: Subsurface Injection of In Situ Remedial Reagents (ISRRs) Within the Los Angeles Regional Water Quality Control Board (LARWQCB) Jurisdiction. Although this in situ remediation document was written for reagent users and appliers in the LARWQCB area, the documents content has much to offer those beyond the geographical region. This is particularly the case in terms of in situ application set up and injection.Read More
