Volunteers needed for one day only! Schools, local groups and individuals are invited to take part in the county wide water blitz. Check the water quality of your local stream, pond, ditch or river and help build a water quality picture for Oxfordshire. For your free sampling pack register today by emailing firstname.lastname@example.org and join in on 3rd October. EarthWatch have volunteered to handle the data and map all results on their global water-hub with the resulting data available to everyone involved.
