What You'll Learn
Diesel fuel is not considered hazardous
Diesel fuel is not considered a hazardous substance, although it is highly flammable and can be dangerous if not handled correctly. In some places, it is illegal to pour diesel on the ground or use it to kill grass and snakes, as it can be harmful to human health and the environment. However, diesel fuel is not specifically listed as a hazardous substance in the Hazardous Materials Compliance Pocketbook or the Hazardous Substances Table. This means that, regardless of its composition or quantity, it is not classified as a hazardous substance.
While diesel fuel is not a hazardous substance, it can still pose risks and have negative impacts on the environment. For example, if diesel fuel is spilled on the ground, it can contaminate the soil and make it sterile, preventing anything from growing in it. In such cases, remediation methods such as burning, pressure washing with detergent, or using a product like Petro Buster diluted with water may be necessary to clean up the spill and restore the soil.
The laws regarding the handling and release of diesel fuel can vary by state and country. For instance, in some states, the release of more than 10 gallons of diesel fuel in an area triggers state involvement. Additionally, during the sale of property, certain states may require soil testing and groundwater testing, with the selling entity responsible for paying for any necessary cleanup. These regulations highlight the potential environmental concerns associated with diesel fuel spills, even though it is not classified as a hazardous substance.
Although diesel fuel itself is not considered hazardous, some of its components, such as naphthalene and benzene, are listed as hazardous substances. These individual components, when present in other solutions, may be considered hazardous. This distinction is important to note, as it separates diesel fuel as a whole from its individual components, which may have different classifications and regulations associated with them.
To summarize, while diesel fuel is not considered a hazardous substance, it is important to handle it with care due to its flammability and potential environmental impacts. Proper storage and spill remediation are crucial to minimize risks and ensure compliance with relevant regulations. By taking appropriate precautions, we can protect human health, the environment, and workplaces from the potential hazards associated with diesel fuel.

Diesel contamination impacts soil properties
In addition, diesel contamination can alter the microbial community structure in the soil. Studies have shown that diesel-contaminated soils exhibit lower bacterial richness and diversity compared to uncontaminated soils. Specifically, Actinobacteria are commonly found in uncontaminated soils, while Proteobacteria are predominantly observed in diesel-contaminated soils. This shift in microbial communities suggests that diesel contamination negatively affects certain beneficial bacteria while promoting the growth of bacteria capable of degrading diesel's chemical components.
Moreover, diesel fuel contains aromatic hydrocarbons, which are responsible for selecting and promoting the growth of specific taxa capable of degrading these compounds. For example, Novosphingobium spp. are abundant in diesel-contaminated soils due to their ability to degrade a wide range of aromatic hydrocarbons. While these bacteria play a role in breaking down diesel components, the overall impact on the soil's microbial community can be detrimental, leading to potential imbalances and reduced biodiversity.
The effects of diesel contamination on soil properties also extend to its physical characteristics. Diesel can make the soil hydrophobic, or water-repellent, which further exacerbates water deficits and impacts plant growth. Additionally, diesel contamination can result in soil compaction, affecting the infiltration of water and the movement of plant roots and soil organisms.
To remediate diesel-contaminated soil, various methods can be employed. In situ bioremediation takes advantage of the natural breakdown of diesel over time due to microorganisms in the soil. Tilling the soil, adding fertilizer, and applying compost can accelerate this process. For quicker results, excavation and replacement of the contaminated soil may be necessary. Burning the diesel fuel directly can also be an option but should be done with caution and in small, controlled amounts to avoid further environmental damage.

Diesel-contaminated soil has higher microbial activity
Diesel-contaminated soil has been observed to exhibit higher microbial activity, specifically in the degradation of aromatic compounds and benzoate. This is due to the presence of bacterial taxa such as Burkholderiaceae, Novosphingobium, Anaeromyxobacter, Pseudomonas, and Rhodococcus, which contribute to the production of hydrocarbon-degrading enzymes. These enzymes play a crucial role in breaking down the diesel fuel and mitigating its environmental impact.
The increased microbial activity in diesel-contaminated soil can be attributed to the chemical composition of diesel fuel, which contains a high proportion of aromatic hydrocarbons. These hydrocarbons serve as a source of carbon and energy for the microorganisms, stimulating their growth and metabolic activity. The microbial community structure undergoes significant shifts in response to diesel contamination, with a lower bacterial richness and diversity compared to uncontaminated control samples.
While the enhanced microbial activity can aid in the bioremediation of diesel-contaminated soil, it is important to recognize the adverse effects of diesel fuel on the overall soil health and ecosystem. Diesel contamination can lead to water and oxygen deficits, impacting the survival of other organisms and disrupting the natural balance of the soil microbial community. Additionally, the process of bioremediation can be time-consuming, requiring months for the diesel to naturally break down in situ.
In some cases, the level of diesel contamination may necessitate more immediate and aggressive remediation techniques. Excavation and replacement of contaminated soil are often considered standard practices to eliminate the source of contamination. However, this approach can be costly and generate large quantities of contaminated waste that needs proper disposal. Alternative methods, such as burning or using detergents and bioremediation agents, have been suggested to address smaller spills or when excavation is impractical.
The choice of remediation strategy depends on various factors, including the extent of contamination, local regulations, and the potential impact on human health and the environment. While diesel fuel is not considered highly toxic, and some states may not intervene unless a certain threshold of contamination is reached, it is essential to address diesel spills promptly to minimize their ecological footprint and comply with legal requirements.

Burning diesel fuel in soil can sterilize it
One method to clean diesel in soil is to burn it off. This can be done by sprinkling small amounts of diesel-contaminated soil into a fire pit with a reasonable amount of wood to keep the fire going. The diesel will burn off, leaving behind dead sand and ash. However, burning diesel in the soil will sterilize it, and nothing will grow in it. To make the soil suitable for plant growth again, organic material will need to be mixed back into the soil after burning off the diesel.
There are other methods to clean diesel-contaminated soil, such as using a detergent and water paste, pressure washing with detergent, or injecting specific catalytic enzymes into the soil. In situ cleaning of the soil can also be done through air-sparging and soil vapour extraction (SVE), where air is pumped down via input boreholes and a vacuum is applied to other output boreholes, allowing the vapour phase of the diesel to flow towards the outputs where it is removed. Another method is asphalt batching, where soil contaminated with diesel is mixed with asphalt. This method costs approximately $65 to $75 per ton.
It is important to note that the process of burning diesel fuel in the soil may not be legal in all areas, and there may be regulations and permits required. Additionally, the Environmental Protection Agency (EPA) may take strict action if they become aware of burning or using a dispersant to clean diesel-contaminated soil.

Cleaning diesel spills with detergent and water
Diesel spills are a critical environmental issue that requires immediate attention. Diesel is a complex mixture of hydrocarbons that can contaminate soil and water sources upon contact. Its lighter components can evaporate, contributing to air pollution, while its heavier components persist in the environment, posing long-term contamination risks. Birds and mammals that come into contact with diesel-contaminated water can suffer skin irritation, damaged feathers or fur, and poisoning if they ingest contaminated substances while grooming. In addition, the inhalation of fumes can lead to respiratory problems, headaches, dizziness, and nausea in humans, while skin contact can cause dermatitis and burns.
Due to the hazardous nature of diesel spills, it is important to act quickly and efficiently to mitigate the potential risks and environmental damage. Here is a step-by-step guide on how to clean a diesel spill with detergent and water:
Step 1: Contain the Spill
The first step is to contain the spill and prevent it from spreading further. Use booms, long floating barriers, to contain and absorb oil on water bodies. For land spills, spread granular materials like vermiculite, peat moss, or clay absorbents to absorb the diesel.
Step 2: Absorb the Diesel
If the spill is small, create a paste of detergent and water. Rub this paste into the affected area with a rag or a broom. You can also use specialised oil absorbent powder or liquid products, such as OS Oil Absorbent Powder or OS Step 1 and 2 Liquids, to neutralise and absorb the diesel.
Step 3: Wash and Rinse
Once the detergent paste or absorbent product has been applied, use water to wash and rinse the area thoroughly. For larger spills, use a garden hose to saturate the area for at least 30 minutes. This helps to drive the detergent or absorbent product deeper into the ground, breaking down the barrier between the fuel and water, and allowing the diesel to be diluted and dispersed.
Step 4: Dispose of Contaminated Materials
Collect and properly dispose of all contaminated materials, including rags, brooms, absorbent powders or liquids, and any other materials used in the cleanup process. Ensure that you follow local regulations and guidelines for the disposal of hazardous waste.
Step 5: Remediate the Soil
Even after cleaning, residual diesel components can remain in the soil, affecting soil fertility and ecosystem health. To remediate the soil, mix organic material such as cow or horse manure into the affected area. This will help to restore nutrients and promote plant growth.
Please note that the steps outlined above are general guidelines, and the specific approach may vary depending on the size and location of the diesel spill. It is important to prioritise your safety and wear appropriate personal protective equipment (PPE) during the cleanup process. Additionally, seek professional help if the spill is significant or if you are unsure about the proper procedures.
