- Surfactant Enhanced Aquifer Remediation (SEAR)
- Pump and Treatment Systems for Contaminated Groundwater
When considering the application of different treatment technologies, our environmental team in coordination with your LSP will first consider the goals of remediation (e.g. removal, separation, containment, destruction). Once the goals are established, the team will consider technologies or groups of technologies to meet these goals. In many cases, multiple technologies are required to remediate an entire site. Several treatment processes are combined to meet the varying requirements of the contaminants affecting the site. The following are a few of the treatment technologies that we employ.
Pump and Treatment Systems
The dual bed system is a packaged system consisting of one clay/coal adsorber and two carbon adsorbers that can be configured in series or in parallel, depending upon the facility requirements. This is the most common type of system that we use and each unit can be customized to meet the flow requirements of the site.
In-Situ Soil Vapor Extraction
Soil vapor extraction (SVE) removes volatile organic compounds from a soil matrix. Air drawn through a soil matrix by a vacuum pump removes contaminated soil gas and induces additional volatile compounds to vaporize. Contaminants are drawn out of the soil with the exiting air and uncontaminated air is drawn in to repeat the process. The most common system is trailer-based which generates sufficient vacuum to influence a large area. We also provide smaller vacuum systems for areas where storage space is a concern or access to the contamination is difficult (typically in basements).
Air Sparging is an in-situ process in which air is bubbled through a contaminated aquifer to remove volatile contaminants. Injected air bubbles move vertically and horizontally in the soil creating an underground air stripping process that removes contaminants through volatilization. The most common air sparging process injects air into the groundwater through injection wells. Volatile compounds that are exposed to the sparged air convert to gas phase. Once in gas phase the volatiles either migrate to the ground surface or are captured via a soil vapor extraction system.
Chemical oxidation technology is based on the oxidative properties of specific chemicals. Through the process of oxidation, groundwater contaminants are ultimately broken down into carbon dioxide and water. To effectively degrade contaminants, the oxidant must come into contact with the contaminant molecules. Ideally, the delivery technique would ensure that the oxidant is evenly dispersed throughout the area to be treated. Chemical oxidation is a proven method of on-site contamination destruction and when used in conjunction with site excavation and water treatment systems it can accelerate site cleanup times.
Ozone used in site remediation is similar to other chemical oxidation techniques. The use of ozone differs from most oxidation processes because you can deliver more continuous oxidation instead of batch applications. Ozone is extremely effective in treating many groundwater pollutants including total petroleum hydrocarbons (TPH). When compared to other chemical oxidation methods, ozone can treat an area in a shorter amount of time and the storage and transportation of dangerous liquids is eliminated.
Anaerobic bioremediation utilizes biological processes to break down or destroy contaminants. Enhanced anaerobic bioremediation aids in speeding up these processes and achieves a higher degree of chemical destruction. Bioremediation can be applied to achieve source reduction or plume-wide treatment, and it may be possible to complete the remedy in as little as 2 or 3 years. But for difficult sites (e.g., DNAPL source areas), it may be advantageous to combine enhanced anaerobic bioremediation with other remedial strategies or measures. The single largest difference between conventional remedial technologies and enhanced bioremediation may be that enhanced bioremediation, if properly implemented, can maintain effectiveness over a longer period of time at a lower overall cost.
Bioslurping is used to remediate soils contaminated by petroleum hydrocarbons. It is a cost-effective in situ remedial technology that simultaneously accomplishes LNAPL removal and soil remediation in the vadose zone, by removing LNAPL, then drawing contaminated soil-gas vapor from the ground. Bioventing of vadose zone soils is achieved by drawing air into the soil due to withdrawing soil gas via the recovery well. The system is designed to minimize environmental discharge of ground water and soil gas. When free-product removal activities are completed, the bioslurping system is easily converted to a conventional bioventing system to complete the remediation.
