This year Scotland starts the season with the highest ever number of bathing waters rated “Excellent” for water quality; 50 compared with 17 a decade ago, with 97% of sites now achieving sufficient or better quality. 

The Scottish Environment Protection Agency (SEPA) have led a science-driven programme of monitoring, collaboration, regulation and investment. As well as environmental monitoring, SEPA have worked with operators and stakeholders across Scotland, including Scottish Government, Scottish Water, local authorities, land managers and communities to improve bathing water quality. As a result, millions of pounds has been invested in wastewater infrastructure, improved agricultural practices and targeted pollution control

Increased public information

Water quality at all 89 designated bathing waters is routinely analysed during the bathing water season, which runs until 15th September. Most samples show water quality meets required standards, but if results show unexpectedly high bacterial levels precautionary advice against bathing is issued so people can make informed decisions while SEPA investigates.  

Like much of life in Scotland, our bathing waters are affected by the weather. Heavy rainfall can wash pollution from fields and streets into rivers and seas, sometimes reducing water quality. Combined sewer overflows, designed to discharge during heavy rain to ease pressure on sewer systems, can also release untreated water. When this happens SEPA advise against bathing between one and three days after heavy rain.
