Details

Dense Non-Aqueous Phase Liquids (DNAPLs) represent a significant source of groundwater pollution in the UK. In a review of pollution of groundwater published in 1996, the Environment Agency identified chlorinated solvents to be one of the top three reported contaminants.

This project reviews the range and effectiveness of existing and new approaches to source treatment of DNAPLs. Specifically the report covers:

  • A review of current and novel approaches to identification and treatment of DNAPL sources below the water table in the US and Europe, and its efficacy
  • An assessment of the relevance of existing international experience and research to application of these technologies to the UK
  • Recommendations for future UK research and development requirements to further appropriate remediation technologies.
