There are many treatment approaches when it comes to treating a range of problems that can occur in groundwater. Many of these methods use a combination of technologies. When considering the appropriate approach, it is important to note that each site should be treated case by case. Since every site offers a different history, background, and unique landscape. REGENESIS, and our team of technical specialists, focus on the specific needs of every site to deliver the best-suited solution. There is a no one-size-fits-all remediation approach. Providing in situ remediation solutions on over 26,000 sites – the REGENESIS team has been involved in a wide variety of sites and is equipped with the technical knowledge and expertise to recommend an efficient and effective remedial design using our technologies at a lower total cost-to-closure.When looking at treatment methods, we can categorize them into biological, chemical, and physical approaches:
Bioaugmentation is an example of a biological treatment method that biodegrades groundwater contaminants like chlorinated VOC’s. Cultured microorganisms are added into the subsurface that expedite the process as opposed to naturally occurring microbial communities. REGENESIS’ BDI Plus® or Bio-Dechlor INOCULUM Plus® is widely used during bioaugmentation and can be applied alongside 3D-Microemulsion® or 3DME® and HRC® products. This bioaugmentation approach generally demonstrates results within one to five years, but has been proven to successfully achieve reduced dechlorination at a notable cost-savings.
In situ chemical oxidation (ISCO) is an example of a versatile chemical treatment method eliminating a broad range of contaminants. During the ISCO process, chemical oxidants are injected or mixed into groundwater to destroy contaminants upon contact. Chemical oxidants include oxygen gas, ozone, and other liquid chemicals. REGENESIS’s PersulfOx® and RegenOx® are powerful technologies that work as catalysts to ensure dependable oxidation.
Pump and treat is an example of a physical treatment where contaminated groundwater is pumped to the surface and then treated using a combination of biological or chemical treatments. This is a more traditional approach used historically to reduce contaminant levels. Since the advent of in situ approaches, more and more environmental professionals are weighing the high cost of pump and treat systems against the more economical approach now offered with biological and chemical methods.
Overall, there are many factors when looking for a groundwater treatment solution. What treatment will prove to be the most effective, whether biological, chemical, or physical, depends on site conditions, contaminant types, and concentrations. In addition, budget, timeframe, and other factors will impact which treatment approaches are selected. At REGENESIS, we understand the complexities involved. Our team will work with you to explore all the possibilities and provide turn-key support to arrive at an effective solution. Please request a design today and thank you for reading!
