Pollution can find its way into urban rivers via surface water outfalls (drains). The Zoological Society of London and Thames21 are recruiting volunteers to help conduct the Pinn Outfall Safari.

This involves surveying stretches of the river and, with the help of a mobile app, mapping and recording the impact of outfalls . This survey will greatly improve our understanding of the river and help to target sources of pollution. The survey will take place during: July and August 2017

You can choose which stretch of the river you want to survey and conduct the survey at a time that is convenient to you as long as it is within the survey period. Where possible the survey will be conducted from the footpath by the side of the river but, in parts, it may be necessary to walk in the river where it is safe to do so. All training and equipment will be provided .

A training session for volunteers will take place at the:

Meeting Rooms, Kings Café, Kings College Road, Ruislip, HA4 7JZ

Wednesday 19th July, 10am-12.30pm
