Project Overview

We are working with Addingham Environment Group, the Ilkley Clean River Group and a range of other green groups along the Wharfe to raise awareness about river water quality.  The project is called “iWharfe: improving water quality in the River Wharfe from Oughtershaw to the Ouse”.  It’s a citizen science project and more details can be found here.

Project Reports

Following the success of our mass sampling day in August, we can now share the first report focusing on the microbiology data. You can view and download the report and official press release using the links below.

Project Poster

We have designed a project poster to publicise iWharfe as an event on social media.  There is one general poster for the project as a whole and five posters customised for the five respective sampling zones which can all be found below.

Sites for water sampling

On Monday, 24th August, we will take water samples from approximately 60 sites along the full length of the river. The samples will be analysed for faecal indicator bacteria, such as E. coli, and nutrient water chemistry, especially orthophosphate, at specialist accredited laboratories. Here is the link to see the sites on Google Maps:

Recreational sites

In addition to the sites for the water sampling, we have also identified approximately 30 sites along the rivers that are frequently used by visitors for swimming, paddling or other river-related recreational activity. On one or more occasions, depending on the weather, we will carry out visitor number surveys of these sites to assess which are the most popular and which are the safest to use on this particular day.

The first visitor survey took place on Sunday 9th August. Click here to view a brief report and some pictures from the day.
