We Dont Bury Waste! We Use Nature To Reclaim It! 


Landfarming is a proven, effective, and sustainable bioremediation technology. Compared with traditional landfill disposal, landfarming provides clients with a convenient and environmentally friendly method of disposal. This method is also preferable to other options due to its cost-effectiveness.

Traditionally, when a someone needed to dispose of petroleum contaminated soil (PCS), the only choice available was to dispose of it in an approved landfill. There, the soil remained contaminated, threatening the environment and haunting the company with long-term liability for whatever damage the contaminated soil may do in the future. L&R uses natures own microbes to breakdown harmful contaminats into naturally occuring compounds, providing PCS generators with a final long-term solution with no future liability.


Our landfarm has been in operation since 2006. We help clients end responsibility for their wastes. Let L&R work with you to develop a custom solution to your waste related-problems. L&R provides complete solutions for pumping, transportation, disposal, and recycling. L&R is a comprehensive provider of non-hazardous petroleum contaminated soil (PCS), organic and liquid waste collection, transportation, treatment and recycling services. We have a zero-infraction record with the Idaho Department of Environmental Quality and the Environmental Protection Agency (EPA).

L&R has become a growing presence in the liquid waste services business for over 10 years, including the last 3 years where we have experienced significant growth. L&R currently conducts business in the Western United States. We have transload facilities to accept waste from all 50 states.

L&R has a new and well maintained 160-acre facility with 7 treatment ponds and over 60-million gallons of storage capacity.


L&R remediate PCS and industrial and commercial wastewater. We can provide tanker transportation, on-site storage, and pumping services. L&R specializes in eliminating liability for our clients. We do not bury waste like a landfill, we process and remediate material, allowing us to recycle and reuse the material eliminating future risk to the Principal Responsible Party.

Landfarming petroleum contaminated soils removes responsibility for the generator because the waste is cleaned up and recycled. PCS sent to a landfill is not remediated and presents ongoing risk to the generator if there is ever a cleanup action against the site.

L&R operates a Tier 2 permitted commercial treatment facility located on approximately 160 acres that was designed for the treatment of PCS. Utilizing landfarming technology, photodegradation processes, and bioremediation processes, L&R’s soil treatment facility have successfully treated over a hundred-thousand cubic-yards of petroleum hydrocarbon impacted soil. Our permit limits waste acceptance at the facility to non-hazardous or exempt PCS, including those wastes associated with UST’s, petroleum production, and refining operations. Waste characterized as non-hazardous by analysis can be accepted on a case-by-case basis.

The L&R Group is a comprehensive provider of non-hazardous petroleum contaminated soils and liquids, organic and liquid waste collection, transportation, treatment, pumping, and disposal services. We accept non-hazardous liquid waste such as grease trap, car wash sump, non-contact cooling water, paper manufacturing, and food manufacturing such as cheese, whey, and milk waste.


Using our laboratory services, L&R will provide soil and groundwater analysis to ensure that sites have not been contaminated, determine the level of contamination, and then determine a suitable remediation plan.


When we are contacted about a food waste (liquid or solid) stream coming into our facility we can test it and determine if it can be fed to livestock, (waste such as milk byproduct or onion peels), or if it needs special treatment. If approved, the waste is fed or placed into one of our treatment ponds, where the liquid is evaporated. Solids remaining after the evaporation process generally consist of decomposed organic matter and are composted, thus providing a useful end-product.


L&R provides on-site remediation services. These sites can be treated using a wide variety of treatment technologies specific to the project characteristics. Please contact our Technical Services Division for additional information.

Once a “profile” of the contaminants are received from the analytical laboratory, L&R is able to accept your petroleum contaminated soil (PCS). Upon arrival at our facility, the trucks are weighed at our facilities certified scales. This provides an accurate accounting of the volume of waste brought to the facility and provides documentation for our clients that the soil was disposed of in accordance with applicable state and federal rules and laws.

The soil is then assigned a treatment cell, where soil is placed in a controlled manner. PCS is mixed with soil amendments such as soil-bulking agents and nutrients, and then they are periodically tilled in treatment cells at our facility for aeration. Contaminants are degraded, transformed, and immobilized by microbiological processes and by oxidation. Soil conditions are controlled to optimize the rate of contaminant degradation. Moisture content, frequency of aeration, and pH are all conditions that may be controlled.

The definition of soil landfarming for PCS, is an aboveground remediation technology used to reduce the concentrations of petroleum constituents through biodegradation and volatilization. This technology usually involves spreading PCS in a thin layer (less than two-feet in thickness) inside a treatment cell and the aerobic microbial activity within the soil is stimulated through mechanical aeration. The enhanced microbial activity results in degradation of adsorbed petroleum product constituents through microbial respiration.

Mechanical aeration allows for volatilization of the petroleum hydrocarbon. Soil landfarming has been proven effective in reducing concentrations of nearly all the constituents associated with petroleum products. Petroleum products generally encountered at underground storage tank (UST) sites range from those with a significant volatile fraction, such as gasoline, to those that are primarily nonvolatile, such as heating and lubricating oils.

Petroleum products generally contain more than one hundred different constituents that possess a wide range of volatility. In general, gasoline, kerosene, and diesel fuels contain constituents with sufficient volatility to evaporate through land farm treatment process.

Lighter (more volatile) petroleum products (e.g., gasoline) tend to be removed by evaporation during landfarm aeration processes (i.e., tilling or plowing) and, to a lesser extent, degraded by microbial activity. The mid-range hydrocarbon products (e.g., diesel fuel, kerosene) contain lower percentages of lighter (more volatile) constituents than does gasoline. Biodegradation of these petroleum products is more significant than evaporation.
