Join our citizen science project and help provide a better understanding of the health of the Wye - for everyone

FORW water monitoring equipment

We will supply all of our volunteers with the following basic kit:

  • HM Digital EC3 probe (to measure conductivity and temperature)

  • Hanna Phosphate checkers and reagent

  • Hach Nitrate test strips

  • Turbidity Tube

  • Syringe

  • Safety gear (gloves and safety glasses)

  • Field guide

Each volunteer will need to source their own vessel for taking a water sample and advice about how to do that is included in the training.

Team leaders in certain areas or tributary teams may also be issued a rain gauge.

How FORW performs water quality testing

You can read our handy guide with instructions on how to take a water sample and use our Friends of the River Wye basic kit. This manual is designed for use in the field and volunteers will be issued with a printed version of this booklet at their training sessions.

For more detailed guidance and information on all elements of water quality testing, please consult this guide put together by Cardiff University which was designed for citizen scientists collaborating on a monitoring programme across the whole Wye catchment.

Video Tutorials

Head over to our FORW YouTube channel to find videos provided by ourselves and Cardiff University explaining how to take a water sample and use our monitoring kit.

Recording and viewing results

We use the Epicollect5 app (click here for Google Android phone Play or here for Apple phones) to record results on to an open platform so that anyone can access the data. You will get details on how to do this during training. Once your results are being logged, you will be able to see them in our dashboard Wye Viz, which is updated every week or so to have the latest data (please be patient as your latest tests will not appear until each update is made). Click here to see a handy video tutorial of how to use Wye Viz.

Health & safety guidance

We’ve worked with Herefordshire Wildlife Trust and Radnorshire Wildlife Trust to compile a risk assessment for our citizen science project.

All of our volunteers will need to fill out a volunteer registration form which will be held by the relevant Wildlife Trust as well as FORW, in order that volunteers are covered under their insurance policies.

Reporting an incident of river pollution

If you see visible evidence of pollution in the watercourse, including significant agricultural runoff, leakage from manure or silage, sewage overflows, build-up of foam or anything else that doesn’t look right, please immediately take pictures and videos and report to the NRW (in Wales) or the EA in England, including any results taken, and identifying yourself as a FORW citizen scientist. While the EA does not provide a way to report online via the link above, they have separatey provided extra guidance from the Environment Agency provided to Friends of the River Wye as to how to report incidents, including an email address to send pictures and videos, which aer hugely helpful for informing the response.

Mote that raised levels of phosphate or nitrate are not necessarily considered direct evidence of pollution incidents, however we have been encouraged to report when there are significant changes - especially if over the “very high pollution” threshold for phosphates of 0.50 (as measured by your Hanna device and described in the Freshwater Habitat Trust’s explanation of how to interpret phosphate and nitrate results).
