The Great Stour Project - River Pollution

The following map shows various potential sources of river pollution in and around Canterbury. Some of these sources are POINT SOURCES i.e. easily visible or detectable contamination which can be clearly pinpointed, like a sewage treatment works (STW). Others are DIFFUSE SOURCES i.e. less obvious and more widespread contamination, such as runoff from over-fertilised or over-manured farmland.

Instructions for Researching River Pollution in the Great Stour:

On the map of below, click on one of the 19 locations shown and decide which one of the 8 categories of potential water pollution might be relevant at that location. When correctly identified, you can progress on, researching details of that particular pollution hazard, first in general, and then with more local details; finally there will be information on preventive measures.

Return to the base map to discover other sites of potential water pollution along the Great Stour. When all 8 categories have been explored, you will then be given EA water analysis data for five sites along the river; it will be your task to apply your knowledge and understanding to try to explain the variations shown. Our over-arching aim is to answer this question: how clean is the Great Stour? Good luck in your research!
