The elevated result at Fraserburgh (Tiger Hill) on the 11th August was most likely attributable to combined sewer overflow discharges and rural diffuse pollution, caused by heavy rainfall the day preceding sampling. This is supported by elevated bacterial counts in the Kessock Burn on the same day. A sample taken on the 15th August confirms that there was no lasting pollution at the bathing water.

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.
