Targeted Microbial Applications

Different remediation problems require different solutions.

When it comes to remediation solutions, it is not always an issue of one size fits all. In fact, in some contaminated site situations traditional remediation solutions just are not viable for a variety of reasons.

Do you have such a site? If so, take a close look at Cameron-Cole’s Targeted Microbial Applications (TMA) technology, which has proven both flexible and effective in many site situations where traditional remediation or pump and treat methods just aren’t an effective option.

TMA is an environmentally-friendly approach that uses contaminant-specific microorganisms that are put into a carrier (ISBR) and installed at the project site where they degrade the contamination. It can be used on contaminated soils, groundwater, wastewater, surface water, and runoff and is especially effective on remediation of petroleum and compounds resistant to traditional remediation technologies, such as chlorinated hydrocarbons and pesticides/herbicides. Results from a recent study commissioned by Cameron-Cole have concluded that TMA can remove 1, 4-dioxane and TCE with the selected microbial consortia. Once installed, the microbes move out into the surrounding media where they consume the contaminants of concern as a food source. The TMA technology works because it is customized to target the specific contaminants and degrade them into harmless or nonregulated compounds.

Compared to more traditional treatment systems, TMA is:

• Cost Effective:
  • Very competitive installation cost
  • Low operations and maintenance cost
  • Cost is much lower than soil replacement
  • Minimizes need for off-site removal and transport
• Flexible:
  • Treats soil, groundwater and free product
  • Effective in low and high contaminant concentrations
  • Addresses a wide range of targeted contaminants
• Minimal impact to the environment and operations:
  • Compatible with surface operations, nondestructive
  • No high pressure fluid injection
  • No air and dust emissions
  • Allows for new construction without demolition of existing foundations
  • Won’t clog systems (no bio-fouling)
• Technologically Adaptable:
  • Toxin specific
  • Aerobic
  • Addresses multiple COCs with one inoculum
  • Regulatory approved

The initial research and development of these systems occurred at Louisiana State University’s Department of Environmental Sciences in Baton Rouge. Cameron-Cole has worked closely with LSU and its licensed technology vendor for several years to gain understanding of the effective deployment of these technologies and their applications. The TMA technology has been tested and used successfully since the early 1990s on over 100 projects in a variety of applications. Furthermore, results are typically beyond those required by EPA and state regulations. In many cases, contaminants are reduced to nondetect levels.

Cameron-Cole is committed to helping our clients achieve the highest level of sustainability in their engineering designs. We will assess your particular situation and evaluate energy saving measures, material components, and assess if our TMA technology is the best option for your particular site.
