PES-31 Applications for Biological Hydrocarbon Remediation
PES-31 applications focus on biological hydrocarbon remediation for petroleum-contaminated soil, groundwater, wastewater, slurries, production pits, and other affected media. PES-31 supports naturally occurring microorganisms that metabolize petroleum hydrocarbons when site conditions provide appropriate oxygen, moisture, pH, nutrient availability, and contact with contaminated material.
These applications are most relevant when the project objective is to reduce hydrocarbon concentrations through biological treatment rather than physically release oil from a surface for mechanical recovery. PES-31 may be used in managed on-site treatment programs, in-situ remediation projects, landfarming operations, wastewater treatment environments, and other remediation settings where biological degradation is practical.
PES-31 Application Areas
Landfarming Bioremediation
Landfarming applications use tilling, aeration, moisture management, and product application to support biological degradation of petroleum-contaminated soil. This approach is often considered when contaminated soil can be treated in a controlled treatment area.
Diesel Spill Bioremediation
PES-31 can support remediation of diesel-contaminated soil and other affected media where biological degradation is practical and site conditions can be managed to promote microbial activity.
Soil & Groundwater Remediation
Biological remediation may be used to address petroleum contamination in soil and groundwater where oxygen, nutrients, moisture, and contact conditions can support hydrocarbon-degrading microorganisms.
In-Situ Soil Bioremediation
In-situ applications support treatment without full excavation when site conditions allow product delivery, oxygen availability, and sufficient contact between the treatment solution and contaminated media.
Production Pit Bioremediation
Production pit applications focus on petroleum-impacted soils, sediments, and residual hydrocarbons associated with oil and gas operations.
Soil, Wastewater & Slurries
PES-31 may be applied in engineered treatment environments involving contaminated soil, process water, wastewater, or hydrocarbon-bearing slurries.
When PES-31 Is Typically Considered
| Condition | Why PES-31 May Fit |
|---|---|
| Petroleum contamination is present in soil or sediment | Biological degradation can reduce hydrocarbon concentrations over time. |
| Diesel or petroleum fuels are present | Microbial treatment can target degradable petroleum hydrocarbon fractions. |
| Excavation or disposal should be minimized | In-situ or managed on-site treatment may reduce material handling. |
| Moisture, oxygen, pH, and nutrients can be managed | These conditions support microbial activity and treatment performance. |
| Project goals allow biological treatment time | Bioremediation is generally a treatment process rather than an instant removal method. |
Application Planning Considerations
PES-31 applications should be evaluated based on contaminant type, hydrocarbon concentration, affected media, site access, treatment timeline, and the ability to maintain conditions that support microbial degradation. Biological treatment depends on environmental factors that may need to be monitored or adjusted during the project.
Important planning considerations include soil texture, moisture content, oxygen availability, pH, nutrient balance, temperature, contaminant distribution, and whether the petroleum is accessible to microbial activity. In landfarming and ex-situ treatment settings, tilling and aeration may improve contact between microorganisms, oxygen, and contaminated material. In in-situ settings, delivery method and distribution are especially important.
Project documentation should also account for sampling strategy, baseline hydrocarbon concentrations, treatment intervals, and follow-up analytical results. These factors help environmental professionals evaluate whether biological remediation is progressing and whether additional treatment steps are appropriate.

Primary Treatment Objectives
Common PES-31 applications are intended to support reduction of petroleum hydrocarbon concentrations, improve on-site treatment options, and reduce reliance on excavation, hauling, or off-site disposal where biological remediation is appropriate. Treatment objectives should be matched to site conditions, analytical requirements, and the remediation standard established for the project.
