METS BIOREMEDIATION

Bioremediation still remains the most cost effective, reliable and natural solution to fully remediate all contaminated soils. METS offers a variety of bioremedial solutions both aerobic and anaerobic through our vendor network to treat almost any organic contaminant or multiple of contaminants. What METS offers is a simplicity that differs from traditional bioremediation, even using the same products listed, by providing a mechanically expanded surface area, metered and reliable application with direct and immediate bio/contaminant contact.

METS can offer not only immediate contact, but we apply up to 1 billion bacteria per gram of soil. At those numbers, the contaminant is overwhelmed and treated in days, where it had taken months or years before. Additionally, METS normally requires only a single pass through the process, saving both time and money while providing a permanent clean-up.

The “enhanced” or “E” in METS, comes from the additional additives of air, nutrients, moisture and pH buffers to optimize the bioremedial agent(s) selected. Our METS enhancement offers a mechanical boost to nature’s own solutions.

METS OXIDATION

Chemical oxidation or Fenton’s Reagent Oxidation is a very effective method for treating low level (100 ppm or less) contaminated soil and cleaning up to very low or non-detect standards very quickly. Again, while oxidation chemistry is known and effective, it is normally cost prohibitive in any contaminant concentrations higher than those listed.

This oxidative method can be used in conjunction with METS Bioremediation in a tandem treatment regime to handle the “lions share” of contamination with METS Bio and “polish” with METS Oxidation. METS makes oxidation chemistry more cost efficient by segregating the (normally) two reagents until they are in direct contact with the contaminant making them more effective as well.

The concepts of METS efficiency by increasing surface area and uniformly applying the oxidative reagent across the soil/ matrix interface translate the same in both METS Oxidation and METS Bioremediation.

METS STABILIZATION

METS Stabilization is very similar to chemical oxidation in that it requires a chemical and catalyst to create a chemical reaction. With regard to stabilization, this can be accomplish with a chemical or bio reaction to “stabilize” the contaminant in place. By producing a chemical reaction with the selected reagent/bio product, if the “total” number is low enough, by stabilizing or reducing solubility, the material in now chemically inert state can remain on site. This method produces a twofold result, in that it meets regulatory closure requirement and is expeditious to perform.

An example of this would be to encounter a low level ionized lead such as pB++ and introduce a stabilizing agent to produce a lead sulfide such as pBS which is not soluble (no longer a threat to groundwater) and is exactly the same chemical structure as the mineral Galena. In many regions of the country/world, this mineral is present as a natural “background” constituent and is accepted by regulators by achieving these “background” numbers.

METS SOLUBIZATION

METS Solubilization is the inverse of the Stabilization reaction described above, whereby we add a reagent to increase the solubility of a contaminant, to flush from the soil, using either of our proprietary solubilizing and collection treatment systems, ie: WESTARR or our METS “TCP” implemented on site for custom application. Both systems are designed primarily for soluble heavy metals, with cost and volume dictating which system/method to use.

Again, both systems provide “on site” cost efficient and permanent solutions to potentially very costly alternatives.

METS SURFACTANT REMEDIATION

In many cases, it is not the contaminant that is the entire issue, but soil chemistry can play a huge part in many clean-ups. When you have an “ionized” or electrically charged soil, such as clay, the contaminant can be electrically bonded or attached to the soil. In older spills/sites there may be enough indigenous bacteria to treat the contamination present, but the contaminant is not “bio available” for normal bio digestion/metabolization.

With the simple addition of surfactant chemistry, the contaminant is “de-bonded” and digested without need for any additional inoculation of bacteria. This is by far the cheapest of all the METS alternatives and the most natural, by fully utilizing the indigenous bacteria present at the site.

WESTAR SURFACTANT / SOIL WASH

WESTARR Surfactant Wash is a completely different process and concept than the METS process listed above. WESTARR or Wet Extraction Soil Treatment And Resource Recovery, is a full immersion soil wash that utilizes surfactant not only as a release agent but as a true physical surfactant converting petroleum solids from soil or drill cuttings to liquid for surfacing and recovery. The surfactants here differ somewhat in that they cannot negatively affect the oil for re-refining and will dissolve/disperse in the refinement process.

WESTARR is specifically designed to work primarily with petroleum hydrocarbons and drill cuttings or contaminated soils in excess of 50,000 ppm. There are several additional steps to WESTARR from the Surfactant Wash, but the remaining steps are proprietary to bring the contaminated media to full regulatory remediation. When WESTARR is patented, these steps will be publicly presented.
