March 2015 will mark the twenty fifth annual gathering of environmental professionals to the Conference on Soil, Water, Energy, and Air. For the past twenty-four years, this annual conference has helped to bring the environmental science community closer together by providing a forum to facilitate the exchange of information of technological advances, new scientific achievements, and the effectiveness of standing environmental regulation programs. The Annual AEHS Foundation Meeting and International Conference on Soil, Water, Energy, and Air offers attendees an opportunity to exchange findings, ideas, and recommendations in a professional setting. The strong and diverse technical program is customized each year to meet the changing needs of the environmental field.

Platform and poster sessions feature research, case studies, and the presentation of new programs. Exhibitions augment the conference program and bring applied technology to attendees. Focused workshops provide attendees with practical information for immediate application. Daily socials provide networking opportunities and discussion.

Multi-Technology Environmental Remediation Solution Provider

June 24th, 2013

Global Remediation Solutoins (GRS) provides the best available environmental remediationEnvironmental Remediation loading equipment solution for both large and small projects including sites dealing with multiple contaminants.  GRS is experienced in a wide array of technologies including thermal, bioremediation and air movement. This technical knowledge base gives our clients the value of receiving the optimal solution through one provider.

GRS has developed its Electric Resistant Heating (ERH) technology to provide a complete, fast and energy-efficient solution for simultaneously treating solvents found in soil, groundwater, and pools deep below the groundwater table. ERH is often used to clean sites where other technologies have had limited success. ERH provides uniform subsurface heating, can be safely applied under buildings, and efficiently treats to depths of more than 100-feet below grade.

The GRS team includes experts in bioremediation, which may be used alone or coupled with other remediation technologies. For example, ERH is even more effective when coupled with bioremediation, either during heating or after heating as a final polishing step.  Heat-enhanced bioremediation is a key step in developing a total plume solution.

Multi-contaminated sites can be effectively treated through our complete array of air movement technologies including SVE, DVE, MPE, air sparging, bio-venting, bio-slurping, recirculation wells, and hot-air injection. GRS employs mobile units to maximize space on sites with difficult access space limitations and on-going client operations.

GRS technical professionals can assist you determine the right and most complete technology solution for your next remediation project or property. Because each site’s subsurface geophysical and contaminant parameters vary, it’s best to start a dialog with GRS staff early in the remedial investigation/feasibility study phase.

ERH-Fast and complete chlorinated solvent clean-up.

June 15th, 2013

GRS Trailer 038 smallIn Situ Electrical Resistance Heating (ERH) is the most effective and efficient technology for the complete remediation of chlorinated solvents. Reaching clean-up goals in months, ERH addresses contaminated soil and groundwater with no rebound. ERH applications include both industrial and commercial sites, from large source areas to small dry cleaners.

Chlorinated solvents, such as PCE, TCE and their degradation products, persist in the subsurface because of their unique chemical and transport properties. After decades of operation, groundwater pump and systems have produced few, if any, site closures for these compounds. This leaves site owners with both persistently impaired property and on-going operation and maintenance costs.

ERH provides property owners a proven, fast, and complete remediation option that enables them to sell impacted property at full value or return it to productive use. The value produced by a quick and certain clean-up can be substantial for many properties.

GRS technical professionals can help you determine if ERH is a viable solution for your next remediation project. Because site conditions and contaminant parameters vary for every project, it’s best to start a dialogue early in the RI/FS process to determine if ERH is a fit for your site. We can also work with your staff to evaluate heat-enhanced bioremediation and heat-enhanced in situ chemical oxidization (ICSO).

Electrical Resistance Heating (ERH) White Paper

June 9th, 2013

When chlorinated hydrocarbons, such as dry cleaning fluids and industrial solvents, are released into the environment, they migrate downward until they reach groundwater. Because they are heavier than water, they continue sinking through the aquifer until they find a layer of tight soil where they form pools of pure product. As these solvent pools slowly dissolve into the groundwater, they feed large contaminant plumes capable of impacting human health and the environment well down gradient of the impacted site.

These solvent pools are often found at depths of over 30-feet below ground surface and 20-feet below the water table, making them impossible to access using conventional remediation technologies. For example, the shoring and dewatering requirements for soil excavation and disposal at these depths represent insurmountable safety, engineering, and cost challenges. grs-3Phase-Diagram

Electrical Resistance Heating (ERH) is an aggressive in situ remediation technology that can simultaneously treat the solvents found in saturated and unsaturated soil, groundwater, and pools deep below the groundwater table. ERH is often used to clean sites where other technologies have had limited success. Using ERH, even large sites can be remediated quickly and completely. The technology is so robust that it can return highly contaminated groundwater to drinking water quality.

Developed for the US Department of Energy, ERH takes power from standard utility lines and applies it to electrodes placed in a grid pattern across an impacted site. As the subsurface resists this application of electricity it is heated to the boiling point of water producing steam and contaminant vapors. Installed to the maximum depth of contamination, ERH systems can heat to over 100-feet below grade.

During ERH, pools of solvents located below the water table are boiled first and this large contaminant mass is quickly removed from the subsurface. Next, steam formed in the subsurface starts driving contaminants out of soil and groundwater. As steam tries to escape from the subsurface, it sweeps contaminants to the recovery wells where they are collected and carried to the surface for treatment.
At the surface, steam and contaminant vapors are condensed into water, liquid contaminants, and cool contaminate vapors. Liquid contaminants are collected for recycling while condensate water and contaminant vapors are treated prior to release to the local sewer system and the atmosphere.

ERH can be applied in flowing gravel aquifers, heterogeneous glacial tills, and tight clays. It can treat fuel hydrocarbons, chlorinated solvents (dry cleaners), and polycyclic aromatic hydrocarbons (PAHs) such as creosote and coal tar. It can be safely used under roads, parking lots, and occupied buildings without disruption of traffic or occupancy. GRS would be happy to review any site for the use of ERH, and an easy to use site evaluation tool can be found on our web site.
