Riverfly Monitoring
As part of the Riverfly Partnership, ARK are part of a national initiative regularly monitoring water quality. Trained ARK volunteers monitor 62 sites on the River Kennet and its tributaries to check the health of the river and pick up otherwise undetected pollution incidents.

Riverfly monitoring is a proven method of picking up pollution incidents that would otherwise go undetected. In July 2013 a major chlorpyrifos pollution event was picked up by our monitors at Elcot Mill, Marlborough and subsequently led to the prevention of any further discharge of this insecticide into the watercourse.
