Chlorinated Solvents – Controlled Water and Human Health Risk Assessment

2014 Summer Workshops

Date: 24th June 2014

Venue: Sheffield Cathedral Centre, Church Street, Sheffield, S1 1HA

Very few areas of the western world are completely free of chlorinated solvent contamination in groundwaters beneath heavily industrialised areas and DNAPL contamination remains one of the major challenges both from an investigation and risk assessment standpoint.  This workshop was designed to bring together some of the UK leading experts in the field and to debate what is best practice in the investigation and assessment of risk from sites, and areas contaminated by chlorinated solvents and how best to approach the risk assessment of these sites, in relation to both controlled waters and human health.  The workshop consisted of a series of presentations in the morning followed by discussion in the afternoon breakout sessions on the following topics:

  • Site Investigation & Sampling
  • Toxicology
  • Groundwater risk assessment and developing guidance
  • Assessment of vapour risk
