Question to the Department for Environment, Food and Rural Affairs:
To ask the Secretary of State for Environment, Food and Rural Affairs, if she will make an estimate of the proportion of unmonitored surface water bodies that would be classified as having a good chemical status using a biota sampling methodology.
It is not possible to monitor biota in every water body. The Environment Agency is considering how to assess unmonitored surface water bodies to inform the classification of chemical status when this is next undertaken in 2020.
