January 2012, Thermo Fisher Scientific (Thermo Fisher), “the world leader in serving science” will now be actively representing REGENESIS’ technologies throughout the Australia and New Zealand regions. This welcomed change comes after several years of successful, ground-laying efforts by REGENESIS, in which support for the region came directly from the Company’s headquarters in California. Thermo Fisher currently maintains its main offices in Scoresby, Victoria and represents a range of environmental technologies including: environmental monitoring devices, soil monitoring equipment, groundwater parameter analysis, hydrocarbon recovery tools, fluids recovery pumps, etc. With a strong and growing technical presence in the groundwater remediation market coupled with product warehousing facilities across Australia, Thermo Fisher is well positioned to service the entire continent and its immediate neighbors with REGENESIS’ proven suite of advanced technologies. The two companies will be working closely in the coming year to increase the level of service and supply of remediation technologies to the wide-range of environmental consulting firms throughout the region.

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.

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.
