New Geoprobe 8040DT to Support Deep Sampling, Well Installation, MIP and Injection Projects
Vironex has seen a strong demand for deeper or more complex sites traditionally not accessible by direct push technology. To meet this demand Vironex, has purchased a new Geoprobe 8040 DT.
We are routinely being asked to provide DPT injection services at sites with target intervals below 100 feet. These requirements can now be met, in addition to associated deep soil and groundwater sampling.
The 8040 DT can also install 2" pre-pack monitoring or injection wells without generation of soil cuttings and IDW.
Vironex has always met the challenges contaminated sites pose to our clients, and looks forward to applying this new technology along with our industry leading injection, direct sensing (MIP/HPT), and 3D visualization capabilities.
8040 DT Capabilities
The Geoprobe® Model 8040 DT is a high-capacity direct push machine with a durable undercarriage, hollow stem auger capabilities, and a wide-base platform. With the GH80 Hammer, this machine is capable of driving 2.25", 3.25", and 4.5" tooling in areas that were previously unthinkable. Designed into the 8040 DT is a long list of features. The machine incorporates a two-speed hydraulic top head for classic auger/drilling methods for lithologies not conducive to direct push techniques. According to Ryan Kejr, Machine Design Engineer, "the head handles the full 80,000 lb. of pullback required for a direct push machine of this magnitude. The 8040 DT head also has an integrated hydraulic clamp to safely and quickly pull rods while maintaining an open ID." All three functions are mounted on a side shift carriage allowing the operator to work the ID of the rod without moving the foot.
Deep MIP/DPT
No longer will deep contamination be restricted to characterization by monitoring wells. Vironex will now be able to drive a new 8040 MIP tool to even greater depths. This means better understanding of mass distribution and corresponding targeting by well or DPT delivery systems. This is an exciting development in site characterization and Vironex is ready to support your deep projects.

Advanced Injection Technology Delivered to the East Coast Region
Vironex is proud to announce the delivery its most advanced injection system developed to date, to the East Coast Region. This new mobile injection system will be deployed to projects across the region to provide cost effective mixing and injection of large quantities of in-situ remedial compounds
Vironex's mobile injection systems are fully self-contained and have integrated heating units, motor control centers, mixers, pumps, secondary containment, water transfer and storage, power, compressed air, hydraulic PTO, and injection monitoring equipment. Vironex provides integrated mixing and pumping systems that can achieve injection rates of 100 GPM and pressures up to 1500 PSI. Reagents are delivered through DPT points or injection wells, individually or at multiple injection locations, through manifold piping.
Please contact your local Vironex regional office for more information regarding Vironex’s injection capabilities and services.

Mid-Atlantic Program Manager
Vironex welcomes Mike Mazzarese to their Washington D.C. Regional Office in Bowie, MD. Mike brings with him an excellent background in sales and remediation project management, as well as an understanding of local geology and remediation chemistries.
As the new Mid Atlantic Business Development Manager, Mike will support customers in applying Geoprobe® sampling technology and Vironex's Contact-Cost Risk Management (C2RM) approach to minimize the risks of in-situ remediation. This approach includes application of both the Membrane Interface Probe, injection pilot testing, and high performance injection systems to provide cost effective contact of contaminants with oxidants, reductants, and bioremediation compounds.
Formerly the Mid Atlantic District Sales Manager for Regenesis, Mike is able to fully understand a consulting firm's needs and expectations for remediation performance. Prior to his role as Sales Manager for Regenesis, he was a project manager for both URS Corporation and SECOR International. Mike holds B.S. and M.S. degrees in Environmental Engineering from The Pennsylvania State University.
"Mike's focus and understanding of the Mid Atlantic regional consultant base, industrial clients and state and federal agencies is a key component of our dedication to serving existing and new clientele," said Eliot Cooper, Vironex National Director of Remediation Support Services. "We are excited to have him further solidify our presence in the Mid Atlantic."
Mike's focus will be to service the Mid-Atlantic (PA, NJ, DE, MD, VA and DC) states. Mike can be reached at mmazzarese@vironex.com or at 410-504-2546

Vironex Geoprobe Certified MIP Specialists Complete MIP Refresher Training
Vironex is one of the few MIP service providers that have achieved Geoprobe’s MIP “Specialist” certification. This certification requires extensive training by Geoprobe, review of deliverables to ensure consistency with the Geoprobe MIP SOP, and refresher training. Vironex has made the investment in “Specialist” certification to provide our customers with the best field performance and quality MIP data for their remediation projects. The following pictures were taken during the training at Geoprobe’s Salina, KS headquarters and show members of our MIP “Specialists” team.

Vironex In-Situ Chemical Oxidation National Survey Presented at Battelle 2006 in Monterey, CA
The effectiveness of in-situ groundwater chemical oxidation technologies is a function of the delivery of reagents into direct contact with contaminants located in the dissolved, desorbed and NAPL phases.
All remediation professionals agree that contact of in-situ remediation oxidants with contaminants is key to successful remediation. However there are no guidelines or design methodologies published to help these professionals design injection approaches to ensure intimate contact.
In order to provide some clarity on this issue, Vironex has implemented a national survey of our consultant customers to determine what methods and design criteria they use to implement injection programs. The survey was completed in March 06 and was presented at the Battelle Conference Monterey 2006 conference.
This Vironex survey addressed the following:
- Reagent Selection:
- What design criteria are used to select a chemical oxidant.
- Reagent Stoichiometry:
- What design criteria are used to address DNAPL, contaminants sorbed to soil, dissolved phase, and scavenging reactions.
- What design criteria are used to define the number of injection events.
- How are bench scale treatability studies used to define oxidant requirements.
- Delivery Selection:
- What design criteria are used to select injection wells, versus recirculation wells, versus direct push injection versus fracturing.
- What design criteria are used to select the length and number of injection zones.
- What design criteria are used to select mixing and pumping systems.
- How are field pilot studies used to finalize full-scale injection design.
- Radius of Influence:
- What design criteria are used define radius of influence in both the saturated and unsaturated zones.
- What design criteria are used to specify reagent injection concentrations and volumes.
- What monitoring methods are used to verify radius of influence in the saturated and unsaturated zones.

Vironex Kicks Off Expansion of New Washington DC Regional Facility With Chemical Oxidation and Reduction Workshop
In celebration of opening our new regional operation’s center in Bowie, MD, Vironex recently hosted a chemical oxidation and reduction workshop for our mid-Atlantic clients. We had a full house and presentations by the leading in-situ remediation reagent companies in the U.S, including Carus Chemical (Permanganate), Regenesis (RegenOx), and Adventus Americas (EHC).
Vironex also presented its new high-efficiency injection rig, including an injection demo, and why delivery of reagents is critical to remediation success.
Vironex also presented its Membrane Interface Probe (MIP) system, and how it can be used to locate contamination in relation to lithology to better target delivery of in-situ remediation reagents.
“I was really pleased with the turnout and the quality of the presentations. Feedback from attendees was that they came away with a much better understanding of chemical oxidation and reduction technologies and remediation approaches,” said Gene Burke, Vironex’s Regional Manager.
“Our new operation’s center allows us to better accommodate the growth we are realizing through our environmental field services that support consultants with soil and groundwater remediation projects,” said Alan Livadas, President.
