This device will use a number of sensors to obtain information about changes in water quality.

It will be used in Britain to predict potential water contamination so steps can be taken to prevent it.

It is still a pilot program which had 91.5% accuracy during its testing period.

It is placed in rivers, lakes and also in rural areas to measure the state of the area. This can help to improve the quality of sea water for swimming.
