Citizen Science surveyors are required to keep the data they collect confidential. The collated data will be used to inform and lobby as appropriate stakeholders, the regulators and the public. It could potentially compromise the effectiveness of this dissemination if site specific or un-processed data leaks into the public domain.

This and the pages below are intended to act as a reminder for the survey methodology.

They are based on the excellent handbook produced by the Friends of the Upper Wye.

Also available below are pdf downloads of the manuals for the various types of testing equipment you will be using.

If you open the reagent sachets following the cut lines you can easily make a quick funnel which helps guide the powder into the cuvette.  https://www.youtube.com/watch?v=nLub5p9vaL4

The tests are designed for use at 25°C, colder temperatures will cause the reaction between the reagent and the water sample to run at a slower rate. In practice for a majority of the year this will have a negligible effect on your readings. In winter when temperatures are much colder it is recommend that you take a sample and let it get to room temperature before carrying out the test.
