Milestones

IET implements its 250th project!

Established in 1998 as a technology vendor and remedial contractor, IET continues to offer our client's new technologies and experience in the implementation of those technologies. Our success is a tribute to the hard work and the dedication of our employees.

Notable Remedial Activities

Deep Well Injection: Application of IET Patent Pending Kelp and Blue-Green Algae process into deep bedrock well. IET injected over a 60' vertical zone via isolation packers kelp/Blue-Green Algae technology for the treatment of TCE impacted groundwater.

Illinois Permanganate Injection: IET applied for a large international consulting engineering company 10,000 lbs of sodium permanganate as a 10% solution to DPT points inside an active manufacture facility during the hours of 10PM and 7AM. Associated with the work was the installation of vapor extraction points and groundwater monitoring. Each point was cored, injected and restored before active manufacturing activities commenced each morning.

Active Dry Cleaner, Memphis, Tennessee: IET applied via DPT our patented “Synergistic” approach (United States Patent 7,129,388) to CVOCs at an active dry cleaner in Memphis Tennessee. This large scale injection project entailed DPT points and infiltration gallery utilization. Over seven days, IET applied: 10,000 lbs of EHC; 3,000 lbs of HRC; 5,000 lbs of ZVI, 5,000 lbs of Sodium Propionate, 20,000 grams of Vitamin B2; 4,000 grams of Vitamin B12; 1,500 lbs of Yeast Extract and assorted microbial nutrients and enhancements.

Active Grain Elevator Remediation with EZVI, Louisiana: IET applied 12,000 lbs of EZVI via DPT points and IET’s patented injection system to locations impacted by the historic use of carbon tetrachloride at one of the word’s largest grain elevators.

Active Turnpike Rest-Stop, Pennsylvania: IET performed a limited injection program to address BTEX compounds applying advanced biotic/abiotic Mineralization.

Equipment

June saw IET fabricate and put into service the newest IET injection system. Continuing to expand on the flexibility of Patent Number 7,044,152, the new unit sports larger mix tanks, parallel gas systems, steam wands and heated feed tanks and a state-of-the-art screw compression system allowing for instant pressures of 200 psig and higher gas flows. As all IET systems, the new unit maintains IET’s commitment to safety with eye wash and safety wash stations, welded stainless steel piping, chemical resistant flooring and advanced feed systems capable of delivering a wide variety of materials to the subsurface.

Patents

July saw IET apply for another technology based patent, adding to the in-house and licensed intellectual property held by the company.

"Method for the Treatment of Groundwater and Soils Using Dried Algae and Other Mixtures", Patent Application #12250618, January 2009

"Method for the Treatment of Groundwater and Soils Using Mixtures of Seaweed and Kelp", Patent Application #6124509, July 2009

Issued:

"Apparatus for In-Situ Remediation Using a Closed Delivery System", Patent Issue Date May 16, 2006 Patent Number 7,044,152

"Method for Accelerated Dechlorination of Matter", Patent Issue Date October 31, 2006 Patent Number 7,129,388

"Method for Accelerated Dechlorination of Matter", Patent Issue Date May 12, 2009 Patent Number 7,531,709 (continuation of "388")

New Employee in Pennsylvania

As IET continues to experience growth across the country, the support and infrastructure of the company requires similar growth. IET in March welcomed Ian Connor into our fold. Ian holds a Bachelor of Science in Environmental Biology from Mansfield University and is pursuing his Masters degree in Engineering from Villanova University. Ian has already contributed to implementation of nearly a dozen sites across the country. Ian is based out of our offices in Pipersville, PA. We are looking forward to Ian’s contributions.

Miscellaneous News and Events

Seminars/Proceedings: IET continues to participate and present in the FMC/Carus/Adventus seminar series. The next seminar is planned for September in Virginia. All our clients are encouraged to attend these seminars where case studies, new technologies, challenges and solutions are openly discussed.

Papers: IET has authored and/or co-authored four papers which were presented as platforms at the Tenth International In-Situ and On-Site Bioremediation Symposium held at the Baltimore Marriott in May 2009. All IET’s papers are available within the IET web site.
