Sediments play multiple roles in the environment; they can be a source of diffuse pollution, a habitat and a resource, or all three. 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.
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.
Almost 20 years ago, CIRIA published Guidance on the disposal of dredged material in land
(R157), which provided some guidance in sampling and which was then valid clean up standard for contaminated sediments. In addition to this, over the past decade many reports have been published in the US, Canada, Australia and Europe on different aspects of risk assessment and management of sediments.
This project will produce a good practice guide for the UK which examines how practitioners can best use these documents and develop more practical guidance to help them when working on UK projects.
CIRIA is currently seeking case studies for this project along with funding and the support of a research contractor.
