Remediation of contaminated land
Ashdown Site Investigation is a Sussex-based company specialising in the remediation of contaminated land.
Remidiation of contaminated land can take many forms such as:
- the cleanup of contaminated sites;
- groundwater quality improvement schemes (including the use of quantitative risk assessment and groundwater modelling procedures); and
- passive and active ventilation systems for buildings constructed on gassing sites.
The On-site remediation technologies are the soil remediation and the groundwater remediation. There are opportunities for technical advancements in soil remediation to address difficult contaminants and environments and to make on-site treatment technologies more efficient and cost effective. Successful proposals will have the potential to fill unmet needs in the market such as technologies that:
- Offer financially viable solutions at smaller sites;
- Provide a higher degree reliability for in-situ applications;
- Effectively interface with construction processes or techniques; or
- Reduce secondary emissions, such as air emissions.
Significant advances are required in groundwater treatment systems to make them more efficient and reliable. Traditional pump and treat technologies, for example are very inefficient at addressing low levels of contaminants that have migrated overlarge areas. Successful proposals in groundwater treatment might:
- Provide alternatives to pump and treat;
- Provide greater assurance that a method has been effective across the treatment zone;
- Improve treatment for dense non-aqueous phase liquids; or Address a wider range of contaminants.
Working with specialist remediation contractors Ashdown Site Investigation is able to offer a complete range of in situ and ex situ remediation advice and site services.
