As part of contract C7466, 50 samples of freshwater and seawater were
collected at 15 sites in the Stiffkey and Glaven catchments and in Blakeney
Harbour during the period June-September 2017. Each sample was tested for
concentrations of the bacterium E. coli using membrane filtration techniques.
The data were reported by the laboratory as colony forming units/100ml and the
results were recorded as Excel spreadsheet.
