Land contamination claims

Legacy contamination and regulatory oversight

Many contamination issues arise from historic industrial activity, sometimes decades after the original operations ceased. Local authorities have a statutory duty to identify and inspect potentially contaminated land and, where appropriate, to determine and remediate it under the Environmental Protection Act 1990. In practice, however, identifying and investigating contaminated sites can be complex and resource-intensive. Public bodies often face funding and capacity constraints, meaning that some sites are not fully investigated unless redevelopment occurs or specific complaints are raised. Where contamination remains present and affects residential property, private legal action may become an important route for affected communities to seek clarity, accountability and appropriate remediation.

How land contamination claims arise

Land contamination claims commonly involve:

• Groundwater contamination affecting private supplies
• Vapour intrusion from solvent plumes
• Landfill gas migration into homes
• Soil contamination in residential gardens
• Industrial emissions depositing pollutants on neighbouring land
• Restrictions placed on property use due to contamination
• Ongoing stigma and loss of property value

In many cases, contamination is not confined to a single property but affects a defined area or community. Where that occurs, claims may be brought collectively.

Contaminants and site types we investigate

We review cases involving persistent and mobile pollutants, including but not limited to:

• PFAS (“forever chemicals”)
• Chlorinated solvents such as TCE and PCE
• Petroleum hydrocarbons
• Heavy metals
• Pesticides
• Landfill gas and leachate

Common sources include:

• Chemical manufacturing sites
• Fire training grounds and airports
• Former industrial and engineering works
• Landfills and infilled land
• Redeveloped industrial sites
• Fuel storage and distribution facilities

Our focus is on situations where there is evidence that contamination has escaped or migrated and is affecting residential property, land or health.

Group claims and nuisance litigation

Where multiple households are affected by the same contamination source, group action may be appropriate.

Hugh James has significant experience in:

• Managing large cohorts of claimants
• Coordinating complex expert evidence
• Advancing nuisance and negligence claims
• Engaging with regulators and environmental consultants
• Handling technically complex litigation against well-resourced defendants

Environmental nuisance claims often require detailed scientific analysis of contamination pathways, hydrogeology and exposure mechanisms. We work with experienced environmental and valuation experts to assess whether a viable legal claim exists.

Funding

In appropriate cases, we typically act under Conditional Fee Agreements (“no win, no fee”), meaning you will not be asked to pay our legal fees if the claim is unsuccessful. Funding arrangements are assessed on a case-by-case basis and will be discussed transparently at an early stage.

What may indicate a potential claim?

You may wish to seek advice if:

• Testing has identified contamination on or beneath your property
• Your private water supply has been affected
• Regulators have issued warnings about soil or water safety
• You have been required to install gas or vapour mitigation systems
• Your property’s value has been adversely affected by contamination
• Your health has been affected
• Contamination remains present and ongoing

Not all contamination gives rise to a claim. Liability depends on whether pollution has escaped, whether damage can be established, and whether the legal tests for nuisance or negligence are met.

We will provide clear advice on whether the evidence supports progression.

Confidential enquiries

If you believe your home, land or community may be affected by industrial or chemical contamination, you can contact our Environment Team for an initial, confidential, no obligation discussion.

When making an enquiry, it is helpful to provide:

• The location of the affected property or area
• Any environmental testing results
• Correspondence from regulators or local authorities
• Details of any mitigation measures
• Information about when you first became aware of the issue

We will assess whether further investigation is appropriate and advise on next steps.
