Wet summer blamed for sewage in sea

The drop in quality is being blamed on last year's wet summer. The Marine Conservation Society says "the likely cause is the increased amount of bacteria and viruses washed into our seas during heavy rain followed by flooding.

"The problem with this type of pollution is that you can't actually see it and the concern is that people are continuing to spend time in the sea without realising the dangers of what may be lurking in the waves and which could lead to ear, nose and throat infections and gastroenteritis."
