Waste
Ashdown Site Investigation Ltd offers a number of waste related consultancy and laboratory testing services. A number of case studies are provided below. If you want to discuss a particular project with one of our consultants then please contact us .
Waste Classification Consultancy, Billingshurst
Ashdown Site Investigation Ltd provided waste classification consultancy services to our client for this residential development. The aim of the work was to give the client advance and better understanding of potential waste disposal costs associated with the groundworks element of the project. As a subscriber to the HazWaste Online tool we were able to classify the dataset (comprising results of over 90 soil samples), in accordance with latest Environment Agency Guidance and European regulations. We were able to provide clear guidance including a site plan, zoning the soils on site according to likely waste classification (hazardous or non-hazardous) and an assessment of likely volumes of materials.
Materials Management Plan, Ravensbourne Kent
Ashdown Site Investigation Ltd prepared a Materials Management Plan (MMP ) for this development site where some 3000m cube of surplus materials required transfer. As part of the project engineers from Ashdown SIte Investigation Ltd attended site and inspected and tested soils stockpiled waiting for transfer. A number of previous investigation reports relating to the site were also reviewed to assess contamination potential of soils to be transferred. The laboratory analysis undertaken confirmed that the soils were free from contamination and suitable for reuse on a recipient site where materials were required to to construct a noise attenuation bund.
The MMP identified materials to be removed from the donor site and where they would be reused on the receiving site. The MMP included a risk assessment of both donor and recipient sites and confirmed that the materials to be moved were suitable for transfer and appropriate for reuse. The MMP also demonstrated why the materials were required at the receptor site. Once completed, the MMP was submitted to a Qualified person for review prior to the transfer taking place.
The preparation of the MMP and transfer of materials provided cost savings compared to costs that would be incurred from the disposal of otherwise clean materials.
Ashdown Site Investigation Ltd. offers services for the inspection and assessment of sites and preparation MMPs and other documentation required to allow material transfers to take place. We have established links with Qualified Persons and can advise on what works will be required to move materials from one site to another.

Landfill Investigation, Brighton, East Sussex
Ashdown Site Investigation Ltd were commissioned to investigate a former landfill in the Brighton area, to report on the suitability of the site for future residential use and confirm whether or not that the site is causing any unacceptable risks in the current use.
The investigation comprised a mix of window sampling and cable percussion drilling, laboratory chemical analysis of soils, installation of standpipes and 12 months of ground gas monitoring. The risk assessment confirmed that remediation would be required prior to use of the site for residential purposes. A Detailed Quantitative Risk Assessment (DQRA) was prepared for the current use. The DQRA confirmed that no unacceptable risks were present based on the current use.
Our involvement in the project gave information to the Council for cost planning purposes and was able to confirm that the site need not be considered as contaminated land under Part 2a of the Environmental Protection Act 1990.
Waste Acceptance Criteria (WAC) Testing Worthing, West Sussex
As part of the redevelopment of a former garage and office site in Worthing, West Sussex, Ashdown Site Investigation Ltd were commissioned to undertake contaminated land and geotechnical investigations prior to and during construction. Works included provision of a watching brief for contamination during basement excavations, waste acceptance classification testing to assist waste stream allocation of excavated soils, ongoing groundwater monitoring and sampling, testing and assessments, regulatory body liaison and remedial verification works. Our investigations allowed delineation of contamination and impacts to groundwater and soils to be assessed. Costs associated with contaminated soil disposal and associated delays to the project were minimised.
Hollingdean Waste Transfer Depot, East Sussex
We were commissioned to carry out geotechnical and contamination assessment for development of this former industrial site (including an abattoir constructed on several metres of made ground), for the change of use to the current material recycling facility and waste transfer station. Our involvement on this project included investigation for geotechnical and contamination purposes (including anthrax testing). We were subsequently employed to validate the bioremediation undertaken on site and confirm that clean up criteria had been achieved.
