22 Dec RPI Group is Bringing the Gift of Remediation to the World
A rich mythology supports the Santa Claus figure. He can twinkle his nose, go down the chimney, and appear in the living room without smudging his red coat or white fur trim. While his impeccable appearance throughout a night of fantastic work amazes us – what about the reindeer?
There’s Dasher, Dancer, Prancer, Vixen, Comet, Cupid, “Donner and Blitzen.” And the most famous reindeer of all, Rudolph. If you’re curious, Donner and Blitzen arise from the Dutch words “thunder” and “lightning.” And you’d need to be fast as lightning to cover the globe in just one night!
So, imagine this as a sophomore physics examination. How many watts are required to move one jolly fat guy and a sled full of toys, assume two toys for every child, to every house in the world within one night?
We may not derive the same result, but we must agree – those are some tired reindeer.
The RPI Group Companies have not covered the globe, certainly not in one day, but in the last year, we’ve worked in 28 states and four continents. It’s not magic. Each job was installed by dedicated people, using proven techniques and time-tested BOS and CAT products. To all of you who made this year possible – we wish you all a wonderful holiday season. Enjoy a break that’s well deserved.
“The Story Behind the Reindeer Lodge”
Santa looked at the old toy shop nestled among the snow-laden pines. The shop held a lot of memories. For years, it lay abandoned and silent. Beneath the floors and in the air, an unfortunate legacy remained.
While Santa knows many things, such as who has been naughty or nice, environmental remediation is not his area of expertise. After discussing the issue with the elves and employing his Santa senses, he learned that RPI produces a product called CAT 100 that operates on two tracks, like a sled; one track is abiotic and the other biotic. Both abiotic and biotic processes degrade the TCE to harmless substances such as ethylene without the build-up of the toxic intermediates DCE and vinyl chloride.
The RPI Group Companies arrived on Saint Nicholas Day with clean trucks, injection trailers, and drill rigs. The injection process was orchestrated as if by elves, but we employ highly trained people. Upon completion of the injection, the site was tidied up as if we’d never been there.
A warm fire crackles in the hearth. A string of twinkling lights adorns the evergreen tree in the corner. Around a round table, the reindeer gather, their eyes gleaming. The annual day-after-Christmas card game inside Santa’s gift to the reindeer — the remediated toy shop property, now known as the “Reindeer Lodge.”
The lodge is a place of relaxation for the hard-working reindeer—a home for new memories.
What’s New with RPI Group?
The book gathers the most important advances in the management of sites contaminated with petroleum hydrocarbons. It focuses on the current state of practice in LNAPL characterization and remediation. Its goal is to provide information and a framework to support improved remediation of petroleum hydrocarbons (PHCs).
by Scott Noland, Edward Winner
In chapter 16, Scott and I present in-situ remediation of petroleum hydrocarbons (PHCs) in soil and groundwater systems using activated carbon (AC). In the chapter, we discuss the characteristics of AC, distribution in response to high pressure, high energy emplacement, and AC dosing in the subsurface. The presented materials show that AC pore types, source material, activation process, and grind all influence AC efficacy in subsurface remediation. The data show that when CBIs are installed by injection or as a permeable reactive barrier, dissolved PHC concentrations typically decrease rapidly, followed by establishing a new equilibrium, after which PHC concentrations decrease over time due to biodegradation. PHC biodegradation, in association with the CBIs, is supported by multiple lines of evidence, such as the reduction in PHCs, the increase in gases, the occurrence of appropriate microbial communities, the identification of genes associated with PHC degradation, the decreases in electron acceptors, and changes in compound-specific isotopes.
