What is causing pollution in Devon and Cornwall's coastal waters?

Record winter rainfall is flushing pollution and sediment, along with nutrients from farm runoff and sewage spills, into the coastal waters.

Are there risks to marine life from the heavy rainfall?

Yes, sediment plumes block light vital for seagrass and seaweed, and toxic algal blooms fueled by excess nutrients threaten marine life.

What is the Environment Agency doing about bathing water quality?

The Environment Agency monitors sewage indicators and uses decades of data to assess bathing water safety, noting significant improvements in water quality across Devon and Cornwall.

E. coli bacteria has been detected in coastal waters after heavy rain.

Record Rain Floods UK Coasts With Pollution

Winter rainfall in Devon and Cornwall has reached unprecedented levels, causing substantial pollution and sediment to enter coastal waters. This influx, exacerbated by mild, wet winters, threatens marine ecosystems and public health as warmer conditions approach.

Scientists are employing advanced monitoring techniques, including satellites and drones, to assess water quality. They are tracking levels of viruses, bacteria, and algal species. Large freshwater and sediment plumes are visible, blocking light crucial for submerged vegetation like seagrass and seaweed.
