Background
Sediments play multiple roles in the environment. It is possible that they carry contaminants, a habitat, a resource – or all three. Contaminated sediments have the potential to pose a risk to human health and the environment, as well as impact commercial, recreational, and navigational uses of waterways.
Freshwater and marine sediments can be contaminated by a range of substances as a result of deliberate and non-deliberate incidents – these can be permitted or unpermitted releases. Many of these incidents are a result of a legacy of centuries of industrial activities.
Management of large-scale contaminated sediment, remedial investigations and remediation projects can be resource-intensive. In the US investigative efforts often cost tens of millions of dollars. Several of the larger superfund remediation projects in the USA are now approaching in excess of US$500 million, including some high profile projects such as the Housatonic River, Passaic River, and Lower Duwamish River.
In some parts of the UK, increased dredging has been carried out in rivers and canals to mitigate flooding. This is likely to increase the pressure on the current capability for dealing with these materials in this country.
This event will explore:
- the current published guidance and on going projects on contaminated sediments - what do they cover?
- how contaminated sediments are being managed in UK fresh water and marine environment
- how the recent dredging to mitigate flooding in some parts of the UK has affected the current practice?
- gaps in guidance and other tools which could help British practitioners in contaminated sediments projects
- good practice and examples.
