The Marine Conservation Society (MCS) today grades water quality at 85% of the UKâ€™s bathing beaches as â€˜Good Standardâ€™ following a mid-summer analysis of water quality data from 553 bathing sites. But MCS warns that the number of beaches failing minimum legal standards for water quality, or only achieving a basic pass, is significantly higher compared to this time last year, and 1 in 8 beaches have suffered a serious short-term pollution incident at some point during the first half of the summer.
Thomas Bell, MCS Coastal Pollution Officer, said: â€œThe vast majority of Britainâ€™s beaches have taken the brunt of this summerâ€™s wet weather exceptionally well. But MCS warned in May that climate change is forecast to bring summers punctuated by violent storms and flash floods, and todayâ€™s report reflects the pollution pressures that such weather can bring. Heavy rain will periodically sweep waterborne pollutants such as raw sewage, organic refuse and farm waste from the land into rivers and the sea. The problem for swimmers is knowing when that has happened.â€
In its â€˜mid-season beach health check â€˜ â€“ an analysis of bathing water quality during the first ten weeks of the summer season, MCS concluded from weekly tests that standards remained generally good on Britainâ€™s beaches, despite weather across the UK during May, June and July being the wettest on record. But storm related pollution has reduced 67 beaches to the basic legal water quality standard â€“ double the number at this point last summer â€“ and 71 beaches have suffered serious one-off pollution incidents.
Thomas Bell continued: â€œMCS is calling on the Government to provide public information on all bathing beaches, advising swimmers that coastal waters can be temporarily affected by increased pollution, with a consequent risk to bathersâ€™ health, after heavy rain. Specific counter pollution measures are needed including expansion of the sewer system to handle large volumes of storm water, and the rapid improvement of an estimated 2,000 failing combined sewer overflows. Increased storm pollution is just one of the many growing pressures on our seas, and MCS is calling for a Marine Act to provide better protection and management for our seas and coasts.â€
MCS urges swimmers to be aware of possible pollution after severe rain or flooding, and where pollution occurs to wait at least 24 hours after the rain stops before entering the sea.
This mid-season beach report is derived from not fewer than ten water quality samples, tested by relevant Government agencies, from each of 553 official UK bathing beaches. The results are published on the MCS Good Beach Guide website www.goodbeachguide.co.uk. The relevant authorities collected the water quality data from 1st May to 28th July in England and Wales, and from 21st May to 15th August in Scotland and Northern Ireland. Water quality continues to be sampled until the 30th September.
