The sample was taken after a period of heavy rain in the catchment following a prolonged dry spell. Although the rain had eased on the day of the sample, the time taken for rain falling inland to reach the sea means this is the most likely cause.

Results explained

The annual bathing water classification is determined using statistics calculated from results taken over the previous four years. The water quality indicators we test for are the bacteria E Coli (EC) and intestinal enterococci (IE). The statistics take account of both the average value and the range of values in the four year dataset.

Single sample results above 500 EC and 200 IE are indicative that water was of low quality when the sample was taken. For inland waters the low quality boundaries are higher at 1000 EC and 400 IE.
