In-Situ Remediation

A+ Environmental Solutions, LLC (AES), specializes in the rapidly growing remediation technology of in-situ chemical oxidation (ISCO), which targets – in place – a wide range of environmental contaminants. Much of the cost associated with traditional cleanup technologies is linked with the physical removal and disposal of contaminated soil. The purpose of this cutting-edge technology is to convert groundwater or soil contaminants into less harmful chemicals without the costs associated with removal and disposal. ISCO is a proven, cost-efficient method of drastically reducing cleanup times, and is often more effective than other, more expensive remedial options.

AES has experience using numerious oxidants suitable for a variety of contaminants and geological environments. Some of the oxidants we use for ISCO include: Fenton’s Reagent, hydrogen peroxide, persulfate, permanganate, and RegenOx™. These chemicals can be mixed and activated by various agents depending on site objectives.  Each chemical oxidant has different advantages. The type and form of oxidant dictates the handling and injection requirements. Various chemical oxidants are employed by AES because they have dissimilar chemical compatibilities, degrees of persistence, remedial objectives, and costs.

Our firm has custom designed and built state-of-the-art injection trailers with the capability to accurately and safely inject a wide range of in-situ soil and groundwater treatments. Included in the AES trailers is a water treatment system to remove chlorine and other contaminants from domestic water prior to mixing for ISCO. Also in a trailer is a 150-gallon-per-minute (gpm) consistent-mix tank for injection chemicals designed by AES.

Among the safety features AES utilizes are emergency shower, eyewash, and personal protective equipment (PPE). We have a rapid donning station with Level A, B, and C PPE, SCBAs, confined space entry and rescue equipment, and respirators are stocked and ready to go. On board all our trailers we have spill containment equipment and supplies, field portable analytical equipment, and water and soil testing equipment.

We have modified a track-mounted, limited clearance, rough terrain Geoprobe® Model 540UD direct push drill rig that can place numerous injection points per day at depths of up to 100 feet. AES stores this drill rig in an enclosed, self-contained trailer for fast and efficient deployment. This Geoprobe system is capable of working on wet, marshy land, and navigating rough terrain and steep slopes. The Geoprobe® is designed to be removed from its propulsion system to fit through 36-inch openings, such as a standard door, and work in an environment with clearance as low as 7.5 feet, such as an office building.

Building movement monitoring tools for injections. Another of our innovations is a tilt meter system modified from one formerly used to measure subtle earth movement, volcanic activity, or dam failure. AES developed this computer-controlled system to allow us to accurately measure cement slab and building movement in real time, as we inject remediation fluids under valuable structures. The tilt meter system allows us to determine injection pressures and reduces the chance of floor slab and foundation cracking and/or subsurface utility and drainage system failure.

Fracturing. Our capabilities include hydrofracturing or fracking – that is, creating subsurface channels in clay soil – using high pressure to effectively inject fluids in compacted soils and dense clays. With our specialized equipment, AES has the pumping pressure capacity of up to 3000 psi and injection volumes up to 150 gpm. We can inject into numerous points simultaneously to quickly get the job done. AES has designed specialized injection-point heads that allow a fast set up and controlled injection.

Mobile Laboratory

AES has its own mobile chemical laboratory designed to field screen a variety of conta-minants. Our lab contains a gas chromatograph, with both PID and FID detectors, an onboard air compressor, helium, and nitrogen gas carriers. We are capable of onsite quantification of vapor, soil, and groundwater, and can have results down to 1 ppb in minutes. Samples can then be sent to a state-certified analytical laboratory if confirmation is needed.

We strive to exceed the expect-ations of our clients.

Our forward-looking advances in ISCO methods, mobility, experience, cost- effectiveness, and customer care set us apart from other consulting and remediation companies.
