Expert Advice Series: Injection of Remedial Reagents

Posted on May 2, 2012 by jmalone

ISRR Document Review Section 3.0 – Pre-Design Considerations and Application Related Issues (Will the Target Section Accommodate the Anticipated Reagent Volume Applied?)

Commentary by Craig Sandefur, VP Technical Services, REGENESIS

This section provides a useful discussion of data that can assist in determining if the ISRR target zone will be conducive to application and acceptance of the remedial reagent volumes anticipated. In short, will the target section accommodate the anticipated reagent volume applied?

A brief discussion is provided on each of 9 varying types of data that can be used to gain a more complete picture of the target zones acceptance capacity. These data in total can assist you in judging the target zones’ ability to accept the application volume and possibly even assist in determining a relative rate of application (fast or slow). I think it’s interesting to note that this discussion incorporates some of the low resolution data that may not be a typical consideration by user/appliers. These data range from the low tech blow counts (soil boring logs) to the latest innovations such as Hydraulic Profiling Tools (HPT) and Cone Penetrometer Technology (CPT) data. This discussion also provides some helpful logic as well as context for using these various data in order to gain a richer view of the target zone.

The second part of this section discusses some of the important application related issues that must be factored into the Project Managers (PM’s) thinking when considering injection of high volume ISRR’s. If overlooked, these issues may range from a lot of unneeded stress to a costly mistake. Of critical importance is the location of subsurface utilities, I don’t think that this needs much more comment beyond its mention however it is always a consideration and you must call “Dig Alert” two or more days ahead of the application date. The second consideration is the location of previous boreholes. This often overlooked pre-application consideration becomes clearly evident after the 2^nd or 3^rd application point is injected and ISSR materials daylight. This can be a particularly difficult problem with more reactive oxidants or excessively high volume reagents like emulsified vegetable oils etc. Day lighting or surfacing of any reagent can require a significant amount of on-site reactive management. Even though the management of such occurrences is not terribly difficult to implement (I will discuss in upcoming posts) it invariably causes a slowdown in application rate and loss in field efficiency. It’s my experience that if a significant set of older generation boreholes are present on a shallow groundwater site that it’s always a good idea to equip the application team with plenty of bentonite and hand tools to allow proper re-sealing of the older set of boreholes. Alternatively, if these are known to be a likely problem, the proper repair and sealing of these boreholes prior to application can end up saving time and money.

Elevated Sulfate vs. Enhanced Reductive Dechlorination

Posted on March 28, 2012 by jmalone

Author: Craig Sandefur, Vice President of Technical Services – REGENESIS

A recent technical paper entitled “Chloroethene Biotransformation in the Presence of Different Sulfate Concentrations” by Marina Pantazida, et al. and published in the Winter 2012 Edition of Groundwater Monitoring and Remediation makes a number of interesting observations about enhanced reductive dechlorination (ERD) under elevated sulfate conditions. The authors clearly provide a recommended upper limit for sulfate (250-300 mg/L) for complete dechlorination to proceed. Of interest to me is their observation that sulfate reduction and reductive dechlorination (RD) proceed concurrently in most studies. This observation is consistent with those of us that have long thought that removal of all sulfate does not have to happen prior to the onset of RD or in order for RD to proceed to completion. For more information on this paper visit the National Groundwater Associations website at ngwa.org to view their online archive or order to order a copy of Groundwater Monitoring and Remediation.

Expert Advice Series: Injection of Remedial Reagents

ISRR Document Review Sections 2.0 and 3.0 – In Situ Remedial Reagent Fluid Injection Mechanics and Pre-Design/Application Related Considerations

Commentary by Craig Sandefur, VP Technical Services, REGENESIS

Introduction: This series of blog entries focuses on a key technical report entitled: Subsurface Injection of In Situ Remedial Reagents (ISRRs) within the Los Angeles Regional Water Quality Control Board (LARWQCB) Jurisdiction. The report was spearheaded by REGENESIS in cooperation with the LARWQCB and the ISRR working group. The primary objective of the ISRR Working Group was to compile general tools and best practices into a reference manual to be used during the planning, design, and field implementation phases of ISRR projects. ISRR projects generally include soil and groundwater remediation via: in situ chemical oxidation, enhanced aerobic bioremediation, enhanced anaerobic bioremediation, in situ chemical reduction, etc. In addition, the Working Group also sought to convey that the safe and successful application of in situ remedial reagents requires a proper understanding of site characteristics, delivery methods, application equipment, and monitoring methodology. Finally, this technical document was also intended to guide practitioners of reagent based in situ remediation in performing cost-effective remediation projects while ensuring minimum impact to the public. Intended users of this technical report include regulators, consultants, and appliers of in situ remedial reagents.

Discussion: This review will begin in Section 2.0 of the ISRR Document with and cover Fluid Injection Mechanics as well as some of section 3.0 which emphasizes Pre-Design and Application Related Considerations. Section 2.0 provides a concise description of how fluid moves when injected in the saturated zone. It provides the reader with a specific discussion as to why fluid mounding occurs upon injection and why its dissipation rate is important in understanding how much remedial reagent the aquifer is likely to “accept”. This section also provides the reader with an introductory review of the mechanism of “day lighting” or “surfacing” of remedial reagents. The discussion in Section 3.0 is devoted to Pre-Design and Application Related Considerations that revolve around assessing the hydraulic characteristics of the target zone. In the pre-design discussion the focus is on relevant data, evaluation and testing that can be used by the reader to gain insight on the target zones relative ability to accept remedial reagents. In many cases evaluation of one or a few of these parameters and/or tests will yield significant insight into the likelihood of application success. The suggested data for collection range from the low-cost, low-resolution (such as review of existing boring log blow counts and/or GW well recharge rates) to dedicated high-resolution in situ logging methods, e.g. Hydraulic Profiling Tool (HPT), Cone Penetrometer (CPT). As personal note, I have had some direct and fairly recent experience with in situ logging technologies and I have found them to be very effective in defining the intervals that should most likely be targeted for remediation. Finally, this section concludes with pre-application recommendations that anyone contemplating ISCO should strongly consider since these lessen the likelihood of damaging subsurface infrastructure and/or “day lighting” remedial substrate. These recommendations are to locate subsurface utilities via a pre-application field inspection and use of Dig Alert and locate and inspect the seal of as many assessment or remediation boreholes as possible. Any borehole found to have inadequately seals should be re-sealed prior to beginning an in situ chemical oxidation field application program. This will potentially save the project manager a substantial number of down time hours. Finally, it is always advisable to obtain any injection permits (as necessary) from your local or state regulatory agency. In the next blog entry of this series I will continue the discussion on Sections 2.0 and 3.0 highlighting some of the more salient points regarding injection methods for the delivery of in situ remedial reagents.

Geo-Seal® Vapor Intrusion Barrier Awarded U.S. Patent

Posted on January 12, 2012 by admin

Contributed by Bryan Vigue, Vice-President of Marketing, REGENESIS

Land Science Technologies^™a division of Regenesis, Inc., is proud to announce that the Geo-Seal^® Vapor Intrusion Barrier was recently granted a United States patent in July 2011. Geo-Seal is designed to prevent contaminant vapors such as VOCs and methane, which come from subsurface sources, from migrating into planned or existing buildings. More specifically, the technology is a composite vapor intrusion barrier comprised of a 60 mil spray-applied asphalt barrier encapsulated between two HDPE layers. This patented approach to vapor mitigation creates the ideal blend between chemical resistance and constructability to provide long-term protection against VOCs and methane gas. Additionally, the Geo-Seal system can be customized to meet project specific needs such as:

1. Buildings constructed in below grade or in the water table
2. The retrofitting of existing structures
3. High-risk sites with extreme levels of contamination

Used on a wide variety of sites across the United States, Canada and Europe, Geo-Seal applications range from fast food restaurants built on former gas stations to residential developments built over legacy VOC plumes. Geo-Seal is often combined with Vapor-Vent^™ for maximum, long-term vapor intrusion protection. Vapor-Vent is a low-profile, trenchless venting technology that is installed in a permeable medium of either gravel or sand and can be designed to actively or passively alleviate the buildup of vapors beneath the structure.

Where warranted, Geo-Seal is an integral part of the site remediation process and can easily be installed in combination with any of the in situ remediation technologies offered by Regenesis.

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

Posted on January 4, 2012 by admin

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.
