Hydrocarbon Contamination

Tackling fuel and oil contamination on construction sites.

Hydrocarbon pollution is one of the most common contamination risks on brownfield and redevelopment sites. Spilled fuels, waste oils and historic leaks can compromise groundwater, pose fire and health hazards, and delay planning approvals. Churngold supports clients in identifying, assessing and remediating hydrocarbon contamination to unlock safe and buildable land.


What are hydrocarbon contaminants?

Hydrocarbons are organic compounds found in fuels such as petrol, diesel and heating oil. They often appear on sites with:

  • Former petrol stations or transport depots

  • Industrial yards with poor drainage

  • Tanks, pipelines or machinery with leakage history

  • Storage or transfer areas for lubricants or solvents

They can persist in soils, create odour issues and migrate into groundwater if left untreated.

Our approach

Churngold works with environmental consultants, regulators and clients to deliver site-specific hydrocarbon solutions.

We provide:

  • Site investigation using soil and groundwater sampling

  • Risk-based assessments aligned with current guidance

  • Remediation planning that balances safety, timescales and cost

  • In-situ and ex-situ remediation techniques such as:

    • Bioremediation (using bacteria to break down hydrocarbons)

    • Soil vapour extraction

    • Excavation and disposal

  • Validation reporting to satisfy regulatory and planning conditions

When to involve us

Get in touch early if:

  • Your site has an industrial or transport history

  • You’ve uncovered visible staining, odours or tanks

  • You're preparing a planning application for a former brownfield site

  • You need support for remediation design and delivery

FAQ

  • What types of hydrocarbons do you remediate?

    We manage contamination from fuels, oils, solvents, and other petroleum-based products, including diesel, petrol, lubricants, and lighter volatile organic compounds (VOCs).

  • How is hydrocarbon contamination identified?

    Through site investigation and laboratory analysis of soil and groundwater. We assess the extent, type, and behaviour of hydrocarbons to inform the most appropriate remediation method.

  • What remediation methods do you use?

    Depending on the contamination profile, we may use in-situ treatments (such as air sparging or bioremediation), excavation and disposal, or vapour extraction systems. Our strategies are tailored to each site.

  • Can hydrocarbon remediation affect construction timelines?

    Yes, if not identified early, contamination can delay enabling works and impact regulatory approvals. That’s why early involvement and a practical remediation strategy are key.

  • Do you liaise with the Environment Agency or regulators?

    Yes. We manage all necessary reporting and consultation to ensure remediation works are compliant and approved for redevelopment.
