Have your say - contaminated sediments event

Contaminated sediments are a leading driver of environmental cleanup in the USA, and addressing contaminated sediments has significant economic, ecological, and social implications. Contaminated sediments have the potential to pose a risk to human health and the environment and to impact commercial, recreational, and navigational uses of waterways. A common goal of most of the regulatory programs charged with managing contaminated sediment is to implement cost-effective remedies that provide source control and long-term risk reduction.

In general, although there are strong regulatory and societal pressures, our ability to investigate, evaluate, and remedy sites has been problematic; there is a clear need for timely, cost-effective remedial solutions and for better mechanisms to manage the uncertainty inherent in sediment investigative efforts. Integrated and innovative approaches are clearly needed in the contaminated sediment world.

In the UK, CEFAS has published some guidance on dealing with dredged contaminated sediments and the Energy Institute’s 2013 report, Guidance on characterising, assessing and managing risk associated with potentially contaminated sediments gave further guidance on the subject.

Recently developed technologies involving addition of high value amendments to sequester contamination in situ holds promise, both in true sub-aqueous systems, and in high value wetland systems where in some cases the risk of remedy (e.g. habitat destruction) may outweigh the risk of environmental contamination.

CIRIA will host an event on 4 November 2013, in London at CIRIA offices where delegates will:

  • receive recent guidance on the subject especially those which are relevant to UK projects
  • gain an understanding of UK and international (USA) trends in contaminated sediment management and some of the complexities associated with sediment sites
  • learn about opportunities to use in situ technologies to manage sites
  • gained networking opportunities with regulators and other professionals who have an interest in this area
  • discuss and identify areas where further guidance will be helpful to you.

Please contact Joanne Kwan at CIRIA to find out more and to register your interest in the workshop.
