River Lea
London, Hackney, United Kingdom
The River Lea flows from the countryside of Hertfordshire to Bow Locks in East London, dissecting North and East London. It suffers from a number of pollution streams including raw sewage from misconnected plumbing and diffuse pollution from roads and agriculture higher up in the catchment. In its lower urban section where it has been canalised, options for naturalising the channel are limited.
Sampling happens from the White House Bridge.
