PEOPLE have been urged to join a citizen-science day of water-testing across Oxfordshire.

Hundreds of people are wanted to sample the water in rivers, streams, ponds and lakes around the county for the Waterblitz event on Monday, April 23.

The result of the biannual testing events, organised by Oxford’s Earthwatch group and Wild Oxfordshire conservation network, help build a picture of the water quality across Oxfordshire. Order a free testing kit at
