River monitoring
An important principle in river guardianship is to focus on a specific area and build up a detailed picture of river health over time. WIth this
in mind, Seething River Guardians focusses on a 5km stretch of the Thames between Hampton Court Bridge and Kingston Railway Bridge.

This stretch includes a lot of different elements including a wide variety of wildlife, the joining of the rivers Ember and Hogsmill and three
Thames Water storm outfalls. We take monthly water quality samples from five different sampling points (S1-S5 on the map) and test for
ammonia, phosphate, conductivity, water temperature as well as visual observations. We conduct additional sampling after events such
as storms or overflow discharge. We also condut a montly survey of wildlife.

Anyone can get involved with recording observations, especially wildlife or pollution. Simply use the form below to let us know what you
would like to report and use the grid references to provide us with a rough location.
