Our approach to substrate dosing is based on site conditions. JRW Bioremediation L.L.C. provides substrates and nutrients for anaerobic bioremediation. The substrates provided include highly soluble materials such as WILCLEAR® sodium and potassium lactate, SoluLac® ethyl lactate, and Wilke Whey® whey powder and slowly soluble substrates including LactOil® soy microemulsion, and ChitoRem® chitin complex.

Fun Facts
Fun Facts - JRW Bioremediation, LLC

Ethyl lactate is a common additive in prepared foods, cosmetics and pharmaceuticals and is considered a “green” solvent.

High Fermentable Content

  • High fermentable content (+98% assay) provides more fermentable mass than standard substrates.

High Purity Substrate

  • High purity grade available with a certificate of analysis for metals content
  • SoluLac™ ethyl lactate is a DOT flammable material and must be shipped and stored in accordance with proper regulatory guidance.

Increase Contaminant Dissolution

  • The solvent effect increases the dissolution of chlorinated solvents sorbed to soil or present as DNAPL

Easy Material Handling

  • Low viscosity; readily mixes with water
  • Low injection pressure
  • Long shelf life if unopened

Increased Substrate Distribution

  • High solubility and low viscosity promotes superior movement in the subsurface

Handling

  • Store unopened under dry conditions at temperatures between 50°F and 85°F.
  • The shelf life of the unopened product is >1 year
  • The opened product should be used within 1 month
  • Diluted products should be used within 10 days to avoid microbial growth and activity which may cause gas buildups in containers and visible growth which may foul equipment.
  • Following injection of material, wells should be flushed with clean water to prevent microbial growth. Wells should be flushed with at least 300% of the total well volume to assure substrate is pushed into the aquifer formation and to prevent biofouling in the well.
  • Equipment decontamination should follow site-specific requirements. In most situations, any product residual should be flushed into the aquifer and then chased with clean water.

Packaging

55-gallon polyethylene drums

  • 485lbs
  • 3-4 weeks lead time required past receipt of PO

Recurring questions we get

F.A.Q

Enhanced reductive dechlorination is based on attaining and maintaining control of an aquifer for a period of time sufficient to degrade all constituents of concern and their daughter products. Attaining and maintaining control of an aquifer is highly dependent on the hydrogeology and geochemistry of the site along with the microbial populations present. Since the hydrogeology and geochemistry is different for every site, a blanket cost can not be given for any specific site. In general, enhanced reductive dechlorination will cost less than $10 per cubic yard of media treated on most non-DNAPL sites. This compares with about $60 per cubic yard for excavation (without disposal) and about $90 per cubic yard for chemical oxidation.

In some cases, MCLs can be attained with enhanced reductive dechlorination. Much more frequently, reductions in contaminant mass of one to two orders of magnitude are common.

Because freight is costed from a warehouse to a delivery point, freight costs are quoted separately. Unless otherwise stated, due to the volatility of the fuels market, freight costs are generally valid for 30 days. Consideration should be given to the receiving facility’s capacity to off load a truck. In situations where the product is delivered to a facility without the capacity to off-load a delivery vehicle, arrangements can be made (for an additional charge) for delivery on a vehicle with a lift gate and pallet jack.

Reinjection schedules should be based on the geochemistry of an aquifer and not on a calendar schedule. In many cases, multiple injections can be spaced further apart over time.

Since the main goal of adding a substrate to an aquifer is to attain and maintain anaerobic conditions for an extended period of time, because of the limited flows clay sites should be ideal for enhanced reductive dechlorination. In practice, clay sites with adequately spaced injection points usually show very rapid response to substrate addition.

Injection spacing should be sufficient to promote robust reductive dechlorination throughout the treatment zone for a time sufficient to attain complete reductive dechlorination. Injection spacing is dependent upon the dissolution rate of the substrate, the dosage, aquifer velocity, and competing electron acceptor and contaminant flux.
