CEDA Working Group on Guidelines for assessing and Evaluating Environmental Turbidity Limits (WGETL)

Turbidity limits are often encountered by the dredging industry around the world and often significant resources are used to comply with turbidity limits. It is therefore very important that the imposed turbidity limits are optimised to protect the local environment.

The Environment Commission of CEDA  established the Working Group called the CEDA Working Group on Guidelines for Assessing and Evaluating Environmental Turbidity Limits for Dredging Operations (WGETL). The WG first met up on 14 June 2018.

  • Their task will be to prepare an information paper on guidelines for assessing and evaluating environmental turbidity limits for dredging. The aim of the paper is to facilitate knowledge exchange on how to assess environmental turbidity limits generally, and which parameters should be included in the evaluation at a local level.
