Water quality

Marine water pollution is an issue that impacts coastal communities across Scotland. Whether from raw sewage discharges, industrial pollutants, chemicals from finfish farming or agricultural run-off, poor water quality causes widespread issues across the coast. These include damage to local marine and coastal habitats, health risks, and local economic impacts.

At its core, this is an environmental justice issue: communities are denied both a healthy environment and meaningful participation in addressing pollution. Communities wishing to test their own waters face prohibitive costs and limited access to equipment, further restricting their ability to act. There is a clear need for accessible information, improved water-quality monitoring, and pathways that enable communities to develop local solutions and hold polluters to account.

Resources

Near-live sewage overflow data: the Scottish Water overflow map shows all Scottish Water overflows on a map, including

  • Which outlets are currently overflowing
  • Where there has been an overflow in the past 48 hours
  • The most recent overflow
  • The time and volume duration of the overflow

Past overflows: Every year, Scottish Water publish its annual ‘overflow event’ data from monitors each March. This is usually published in the spring of each year.

Bathing water profiles: this shows where Scotland’s bathing water points are, as well as information about potential pollution sources, measures taken to improve water quality, and sources of further information.

Catchment areas for bathing water sites: This dataset shows the areas of land where all precipitation and surface water naturally flow toward a bathing water site.
