HUNDREDS of volunteers will spend four days testing water pollution across Oxfordshire.
The eighth Thames WaterBlitz starts tomorrow, where non-scientists will test for phosphates and nitrates in ponds, lakes, ditches, springs, streams and rivers.
They will use simple water-testing kits, provided free-of-charge, to identify key pollution sources or clean water areas that act as refuges for wildlife.
It is organised by Citizen Science and coincides with tests carried out on the non-tidal River Thames by scientists from the Centre for Ecology and Hydrology (CEH).

Sharing the data with the Environment Agency, CEH and Catchment Partnerships helps to fill gaps in organisations' knowledge about the environment.
