NAPL in the UK context, does it matter?

One-day conference at The Priory Rooms Meeting & Conference Centre

Bull Street, Birmingham B4 6AF

Wednesday 6 November 2019

From petrol and diesel to chlorinated solvents and coal tar, the UK has a legacy of non-aqueous phase liquid (NAPL) contamination beneath the ground. In this, the Geological Society's “Year of Carbon”, the Contaminated Land Group invite you to join a one-day conference looking at characterising and managing NAPL.

Published in 2003, the Environment Agency Illustrated handbook of DNAPL transport and fate in the subsurface, warned readers that the science of assessment and remediation was new and evolving. With publication of CL:AIRE’s LNAPL Companion in 2014 and guidance on Petroleum Hydrocarbons in Groundwater in 2017 questions are raised: 

  • Where does this leave the assessment of accidental or legacy releases? 
  • What advances have we made and what is the current regulatory position?

Sessions on the day

  1. Keynotes on dense and light non aqueous phase liquids
  2. Existing guidance and its application in the UK
  3. Assessing risks from non-aqueous phase liquid
  4. Remediation of non-aqueous phase liquid

There will be keynote presentations from sector leaders and a series of 20-minute presentations followed by question-and-answer sessions.

Poster competition

A poster competition will also run throughout the day.

Abstracts for poster submissions are now closed.
