A New Year and a New Series of Posts on the Subsurface Injection of In Situ Remedial Reagents

Contributed by Craig Sandefur, V.P. of Technical Services, REGENESIS

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. In my opinion, this document contains some good advice by some very solid users, appliers and vendors that collectively speaking have “untold” years of experience in the proper handling and injection of remedial reagents. The report can be found here.

There are 15 authors listed on the in situ remediation document, the background of these authors range from consultants to regulators and from contract appliers to product vendors. I think it noteworthy that each of the authors provided significant and important contributions to the piece and that their perspectives and experiences are reflected in the documents practical and hands-on approach to in situ remedial reagent injection. This document is full of information on the set up and injection of reagents as well as remediation monitoring programs. In blog posts to come, my aim is to cover individual sections of the document with some brief insights and commentary.
