Whilst the algae blooms witnessed along the coast are nothing new there are a couple of observations I will make. First the bloom often referred to as May bloom is earlier than normal and secondly the amount of surface froth is unusual and whilst large spring tides and a big surging swell have contributed I personally consider that this could be largely due to extensive run off from rivers into the Bristol Channel carrying worrying levels of enrichment from agricultural run-off and sewage overflows.

There is increasing awareness of the many issues that impact upon water quality with considerable focus on rivers with many groups with environmental interests now joining together to campaign for a revision into how we manage our environment. This is certainly complex and requires extensive effort across government and society.
