Where Could I Survey?

Use our Clean Water Testing Kits to Survey any waterbody you want and as many as you want! A petite pond, local lake, babbling brook, rolling river….

For us to get a clear picture of water quality across the Thames region it is good to vary your locations, waterbody types or surveys over time.Revised-habitat-map TB

Ask yourself question to investigate!

  • What nearby nearby water bodies are there?
  • If one pond comes out unpolluted what about the one next to it that has fish?
  • If you are surveying a stream or river do any other water bodies feed into it and how does that affect the water?
  • Does the water quality change over time in a river or stream?
  • What differences do you find between water bodies?

There are lots of interesting answers we can find out by asking simple questions like these.

Once you’ve decided where you want to test just go collect your water sample and follow the instructions on how to use your Clean Water Testing Kit in our leaflet that come with the kits.

We are only looking at freshwater within the Thames Region so please refer to this map for guidance

Get to know freshwater:

IMG_6293Pond: Still waters between 1m2 and 2ha in area. These can be permanent or temporary. Both man-made and natural waterbodies.



Garden PondIMG_6317: All in the name really. As above, but within a garden or within the boundary of your curtilage



lake get to know

Lake: A very large body of still water >2 ha in area, includes reservoirs and gravel pits.





Page 1_figure 2_eye stream (2)Stream: Small running waters, created mainly by natural processes. Marked as a single blue line on 1:25,000 Ordnance Survey (OS) maps and defined by the OS as being less than 8.25 m in width. They have a more sinuous outline than ditches and follow natural landscape features, e.g. valleys.


2013_0629veryendjune20130023Rivers: Largest running waters, created mainly by natural processes. Marked as a double blue line on 1:25,000 OS maps and defined by the OS as greater than 8.25 m in width.



ditch get to knowDitch: Man-made channels created primarily for drainage, they often (i) follow a straight line, (ii) follow boundaries e.g. field or road edges, (iii) turn at right angles, and (iv) show little relationship with natural landscape contours.



canal get to knowCanal: A feature created for navigation which may or may not still be navigable. Usually deep with steep side




other get to knowOther places to test
You might want to sample your water butt, or the water from your tap, particularly if you want to ‘try the kits out’, but it would be interesting for the survey if you can sample from another freshwater habitat in your neighbourhood as well.
