Monitoring our reach

Results from the HoTWater group in Henley provide a useful indication of conditions downstream, but they do not specifically reflect water quality at Wargrave and Shiplake.

SWIM are concerned about the health of our river, and the people who enjoy it, so we plan to:

• Take weekly water samples at one or more locations around Wargrave and Shiplake, between May and October.

• Take occasional samples upstream and downstream of Wargrave Sewage Treatment Works.

• Use Roth R-Cards (Surfers Against Sewage link), to test the samples for E. coli bacteria. 

Sponsors

Testing for E. coli does cost money — but by using R-Cards, we can keep the cost down to around £11 per test**.  

Tests have already been sponsored by Henley Sailing Club, and by local river users and residents. 

If you would like more information or would like to sponsor one or more tests, please contact us at:

Once we have seen results from some initial tests, we will ask for sponsorship, and will acknowledge the sponsors here:

** £11 is based on the price that we actually paid for our first batch of tests. The price of tests is likely to vary over time, but all monies raised will be spent on buying as many tests as we can. If funds allow we may also include occasional lab based tests.
