Contaminated Land

Land Contamination issues?

The recent growth in residential housing construction has seen developers look to regenerate former brownfield sites that were previously considered to be non-viable.  Ardula can assist in the commercial evaluation of the contamination issues and offer a range of solutions, from simple 'dig and dump' at competitive rates, to various value engineered options such as soil stabilisation or other on site processes, conducted using Ardula's two Environment Agency Mobile Treatment Permits.

The permits are active in two parts.  The overall permit allows the activity, and a site specific deployment is then granted by the EA on a project for project basis

  • Permit SR2010 No. 11 allows the treatment of waste at the place where it is produced or at the place where the waste is to be used. This allows its use on temporary sites of construction or demolition in England and Wales to produce soil, soil substitutes or aggregate from specified wastes produced on the site or from specified wastes brought to the site for use on that site after treatment, to a limit of 75,000 tonnes under any one deployment.  It allows treatment of specified wastes using technology and associated plant necessary for treatment and associated storage, to include mobile plant consisting only of sorting, separation, screening, crushing and blending of waste for recovery as a soil, soil substitute or aggregate.

  • Permit SR2008 No. 27 allows the treatment of soils and the treatment of contaminated material, substances or products, for the purpose of remedial action with respect to land or controlled waters.  Ardula Limited will be allowed to use the following technology and associated plant necessary to facilitate the treatment or remedial action, including the use of that technology and plant in combination with others listed: Air sparging; Bioremediation – insitu and exsitu (windrows, biopiles, in-vessel bioreactors); Soil Washing; Solidification; Stabilisation; Use of Treatment plant for sorting and separation, and for blending, mixing, bulking, screening, shredding, particle size reduction and / or particle separation in order to facilitate remedial action. This permit allows waste recovery activities. Please note that any processed materials will continue to be regulated as waste until they meet the end of waste test in accordance with Article 6 of Directive 2008/98/EC. We can demonstrate that we have met the end of waste tests by following either: a) meeting all the criteria set out in any relevant and applicable EU End of Waste regulations; or b) a case by case assessment taking into account the applicable case law, which includes meeting all the requirements of a relevant and applicable Quality Protocol or Defined Industry Code of Practice (e.g. CL:AIRE Development Industry CoP)


These permits allow us to improve our ability to offer value engineered solutions on contaminated sites, as a single operator solution to include the treatment and haulage of waste materials, and are a good addition to our business overall.
