Bioremediation Projects Utilizing Land Reclaimer

Completed in the State of Washington

Levels of Contamination vary among the project sites. Reduction of Total Petroleum Hydrocarbons (TPH) contamination levels to target levels based on parts-per-million resulted in Site Closure.

GMS Land Reclaimer Case Studies - Johnson

Tulare County, California

The County treated a 15,000 square foot area contaminated by a diesel fuel spill. The intial hydrocarbon count was at 3,600 parts per million (PPM). Treatment methods of discing (aeration) and sprinkling were used to treat the area. The hydrocarbon count after six months was 3,000 PPM.

The firm of Leedshill and Herkinoff, located in San Francisco, California, performed laboratory testing of the contaminated soil. A test program was conducted, involving the sprinkling of a dilution of water and Land Reclaimer product on the contaminated soil. The hydrocarbon count was reduced to below 100 PPM within 24 hours.

Dry Cleaner Remediation, Washington

The subject property was a dry cleaning operation located in Seattle, WA. Soil sample testing indicated a contamination level from tetrachloroethene of 1.39 PPM. The Department of Ecology soil cleanup criteria is 0.5 PPM.

Injections of Land Reclaimer were applied through bore holes to weaken the hydrocarbon bond with the soil through an ion exchange process. The hydrocarbons are then more readily available for naturally occurring indigenous microorganisms to eat and accelerate the degradation of the hydrocarbons. Additionally, a proprietary blend of microbes were then added six days later. The soil was then left for approximately three weeks to allow the bacteria to multiply and degrade the perchloroethylene.

Analysis of halogenated volatile organic compounds by EPA Method 8010 (modified) indicated reduced levels of tetrachloroethene as per the following sample PPM:

Tetrachloroethene Contamination as per PPM
Sample 1 Sample 2 Sample 3 Sample 4
0.313 PPM 0.201 PPM 0.108 PPM 0.254 PPM

All samples indicated a PPM reading lower than the Department of Ecology soil cleanup criteria of 0.5 PPM.

TPH Cleanup, Washington

The subject property was located in Woodinville, WA. Geoprobes were placed in the vicinity of a former underground storage tank (UST) excavation. Test results indicated the site contained concentrations of TPH-gasoline in the soil and concentrations of TPH-gasoline, TPH-diesel, and TPH-oil in the groundwater above the Department of Ecology Model Toxic Control Act (MCTA) Method A cleanup criteria.

Injections of Land Reclaimer were applied through bore holes to weaken the hydrocarbon bond with the soil through an ion exchange process. The hydrocarbons are then more readily available for naturally occurring indigenous microorganisms to eat and accelerate the degradation of the hydrocarbons. One week later, a proprietary blend of microbes were injected into the site. The soil was left for approximately three weeks to allow the bacteria an opportunity to multiply and degrade the hydrocarbons.

Subsequent analysis of TPH compounds by EPA Method 8021B, Method NWTPH-Gx, and NWTPH-DX indicated that none of the soil samples or groundwater samples had concentrations of any of the TPH or BTEX compounds detected above the reporting limits (Laboratory Data available).

Hydrocarbons Cleanup, Zagreb, Croatia

Bioremediation of hydrocarbons (diesel fuel) was conducted at the oil field Zutnica in Croatia. Two pieces of land measuring 15 sq. meters each were contaminated with 238 liters of diesel fuel. Penetration of the diesel was recorded to a depth of 15 to 20 cm.

One area was treated with the Land Reclaimer product. Injections of Land Reclaimer were applied through bore holes to weaken the hydrocarbon bond with the soil through an ion exchange process. The hydrocarbons are then more readily available for naturally occurring indigenous microorganisms to eat and accelerate the degradation of the hydrocarbons.

Subsequent testing indicated the following results:

  • Land Reclaimer had no toxic effect on native bacteria, or on fresh water snail species Planorbarius curcus.
  • Microbiological investigations indicated a significantly faster growth of autochthon bacteria on samples treated with the Land Reclaimer solution, in contrast with samples untreated by Land Reclaimer.
  • Soil treated with the Land Reclaimer solution contained only traces of oil extracts - the remaining hydrocarbon content was less than 1 percent in comparison with the control sample. This occurred after 45 days.

Kauai Hilton Hotel Project

The process was initially tested on contaminated soil from an underground storage tank site at the Kauai Hilton Hotel. Average TPH’s were reduced from 1,940 ppm to 31 ppm after 71 days of Land Reclaimer treatment.

Ilikai Hotel Project

A short-term test was performed on contaminated soil obtained from the Ilikai Hotel to examine changes in hydrocarbon distributions (aliphatic, polynuclear hydrocarbons (PAHs) and the unresolved complex mixture (UCM) following implementation of the Land Reclaimer process.

Following eight days of treatment, the total petroleum hydrocarbon (TPH) content of the treated soil was reduced by 33% relative to the untreated control, corresponding to a 4%, 23%, and 32% reduction in aliphatic hydrocarbon, PAH, and UCM content, respectively.
