Contaminated land

In common with many other countries, the UK has a legacy of land contamination arising from industrial development and related operational practices.

The Stroud District has a long history of industrial activity, the basis of which was the wool and textile industry, along with associated processes such as the manufacture of dyes. In addition the District was host to a wide variety of other industrial uses including brickworks, gasworks, lime burning, quarrying, wire manufacture, fellmongery and tanning, board manufacture, fireworks, artificial manure and land filling operations.

These industrial activities often resulted in contamination of the land, which, if not properly dealt with, can pose a risk to public health and the environment.

The type of contamination varies from site to site, and is not always visible. Not all contamination poses a problem; some may only be a concern when the land is used for a particular purpose.

The Council tackles contamination in a number of ways; through the planning process, through the Inspection Strategy and through prevention.

All planning applications are checked to see if they are situated on land known or suspected to have had a potentially contaminative former use. Where appropriate, conditions are applied requiring the developer to carry out an investigation of the site and where necessary to undertake remediation (clean-up) if contamination is found. Remediation must be to a standard that makes the land suitable for the proposed use.

It is a statutory duty under Part 2A of the Environmental Protection Act 1990 to identify contaminated land and to ensure it’s clean up. The Council has produced a strategy for the identification of contaminated land setting out how it intends to carry out its duties under this legislation (see below).

The Council has a duty to regulate a number of industrial processes which could give rise to further land contamination. The Council works closely with various regulatory partners, including the Environment Agency, to prevent new contamination being caused, or to require clean-up by the responsible polluter.

Further information

The Council’s Strategy for the Identification of Contaminated Land details how the Council undertakes the identification, prioritisation and inspection of potentially contaminated land. (Please note that the Strategy is currently being revised and the new version will be available shortly).

Frequently asked questions about contaminated land

Part 2A of the Environmental Protection Act 1990 introduced a legal definition of

Contaminated Land. The legislation states: "Contaminated Land" is any land which appears to the local authority in whose area it is situated to be in such a condition, by reason of substances in, on or under the land, that:

  • significant harm is being caused or there is a significant possibility of such harm being caused; or
  • pollution of controlled waters is being, or is likely to be, caused

It is important to note that land that does not fit the legal definition of Contaminated

Land may still be affected by contamination.

Many industrial processes have the potential to cause, or have caused, contamination of the ground. Industries that have previously been present in

Stroud include wool and textile mills, dye works, gasworks sites, petroleum storage sites, engineering works, railway land, metals processing and timber yards.

Contamination can also arise as a result of landfilling, illegal dumping, accidental spillages of substances or leaks from underground tanks and pipes.

In many circumstances no action will ultimately be necessary, because the level of contamination present will not present a significant risk to health. Where levels of contamination are more severe, clean-up will be required, to ensure the site no longer presents an unacceptable risk to public health or the environment.

There are often many different ways a site may be remediated, depending on the type of contamination present and the specific nature of the site. Often contaminated soils are simply excavated and removed from site for disposal. Alternatively a layer of clean soil might be placed above the contaminated soils, to prevent contact or a range of other protective measures, such as ventilation systems, can be incorporated into buildings to prevent the build-up of harmful gases or vapours.

A number of new technologies also exist for treating contamination. Where these are appropriate the Council will view use of these technologies favourably as they avoid transport of contaminated soil to landfill and are therefore more sustainable.

Where a contaminated site is being redeveloped it is the developer who is responsible for ensuring safe development and pays for any investigation and remediation required.

Should a site be legally determined to be "Contaminated Land" under the regulations, then it is usually the person or organisation that originally caused the contamination that is responsible for any clean-up required. In some circumstances, where the original polluter cannot be identified or no longer exists, then liability for remediation may fall on the current landowner. In certain circumstances the landowner may also be unable to pay for remediation, in which case final responsibility may fall to the District Council.

If you are buying a new home your solicitor will conduct a standard search of our Register of Contaminated Land. In addition the Council maintains a database of sites that have had a former potentially contaminative use, and may also hold additional information regarding potential contamination, investigation or clean-up undertaken. An environmental search will often identify previous potentially contaminative land uses that may have been present in the vicinity of a property.

Anyone can request information from our records for a specific property in Stroud District. All such requests should be submitted by email (or in writing) to the Senior Contaminated Land Officer. Requests should include a location plan clearly showing the boundary of the site in question.

In response to such enquiries the Council will provide factual information only. A specialist environmental consultant should be engaged if interpretation of this information is required.

Please note we may not always have sufficient information to answer your enquiries fully.

The Council publishes a guidance document for homeowners and prospective homebuyers affected by potential land contamination.

Environmental searches may raise questions about potentially contaminative land use. The Council may hold more specific information about individual sites, and planning conditions imposed during development of former industrial land. Ultimately it might be that a property is located in an area subject to a previous potentially contaminative use, no further information is available, and the site therefore is scheduled for further inspection as part of the Council's Inspection Strategy. In such circumstances the buyers/sellers involved will have to reach their own understanding of how they wish to interpret and react to the available information. In some circumstances individuals may wish to undertake their own ground investigations, or consider available insurance products.

The Contaminated Land Officer will be happy to respond to all enquiries and will offer advice and assistance on such matters, wherever possible. Note that a charge may be made for providing a written response to enquiries in some circumstances. The Council publishes a guidance document for homeowners and prospective homebuyers affected by potential land contamination.

If you have made a planning application relating to a site that is considered potentially contaminated, then you may have a specific condition attached to your Approval Notice. The presence of such a condition does not indicate that the site is contaminated, only that the Council feels further assessment or works are required to ensure that the development can be implemented with adequate regard for environmental and public safety.

The wording of planning conditions is designed to cover a broad range of issues on a variety of sites, in many cases the work required will be simpler than the condition

wording suggests. Please contact the Council’s Contaminated Land Officer to discuss the specific details of your development. The Council publishes a guidance document for developers of potentially contaminated land and their advisors.
