Bathing water quality

All the beaches in our area passed the water quality test. Kimmeridge only achieved the minimum standard. Would you recommend going for a swim in the sea and where is the best place to swim?

Would not go in after a heavy down pour . All that sewage going down the drains and into the sea :(

Which raises the old question: where do the creatures living in the sea do their 'business'?

So that's why the sea tastes salty :0

Re the above:- It’s the salt which digests the 'business' (and corpses) of the sea creatures, helped by the constant movement due to tides.

Outflows of 'fresh water' do not have salt so locally change the density of the sea and solids sink because of the reduced buoyancy due to the lack of salt. I have witnessed first hand major oil spills sink when they reach a river discharge into the sea, Arabian, Mexican Gulf etc. ~ (even landing a helicopter on the oil slick and taking samples, walking around). The sunken slick hits the sea bed and the rolls up like a Swiss Roll gathering sand, stones and plants from the sea bed, the hydrocarbon then becomes a source of high protein and prolific growth occurs.

Pollution from human ‘activity’ is the real culprit, world population growth from 5 to 7 billion since 1960, we are an infestation on Mother Earth, each human generates the equivalent heat/energy of a three bar electric fire, the cause of Global Warming? (Provide contraception not vitamins to the third world).

During the last fifty years however we have done an enormous amount to reduce the discharge from water courses, all outflows are now processed and only purified water discharged, unless there is excessive discharge due to cloud bursts or storms. A prime example is the Pier Head at Bournemouth which has under it a vast system for receiving the sewage and pumping it towards Hurn alongside the Wessex Way to the sewage treatment plant.
