Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government what steps they are taking to improve water quality monitoring; and how many water quality monitoring stations are currently in place.

The Government’s new White Paper sets out once in a generation reforms that will transform the water system, including improvements to water quality monitoring. It sets out our commitment to ending ‘operator self-monitoring’ and to developing a new strengthened Open Monitoring approach for monitoring wastewater.

The Environment Agency (EA) currently undertakes water quality monitoring at 13,000 locations each year. Water quality monitoring is set to expand significantly by 2030 with the introduction of continuous water quality monitors at 25% of all applicable storm overflows and waste treatment works, and the installation of event duration monitors at 50% of all emergency overflows.

More broadly, the EA is actively exploring the potential for innovation, integration of data collected by other organisations and citizen scientists, and other opportunities to improve water quality monitoring. The EA is planning to integrate new data with its own monitoring to improve its understanding of water quality.
