What is water quality?

Bathing water quality refers to the amount of bacteria present in the sea, which can vary from beach to beach, and can change daily, even on the same beach. High levels of bacteria can indicate pollution from sewage treatment works and storm overflows or run-off from agricultural and urban areas.

Water quality is usually reduced for 24 to 72 hours after heavy rainfall.

Beach Cleans

We need you!

Our volunteers have been surveying rubbish on  UK beaches for over 20 years. In that time shoreline litter had more than doubled and plastic has gone up by 180%!

MCS beach cleans are run all year round All year round Beach Clean events with our flagship event 'Great British Beach Clean' Great British Beach Clean - 18th to 21st Sept in September.

Volunteers record the litter they find - we use this information to help Governments and industry understand how to stop the rubbish getting there in the first place. We also promote behaviour change among the public using the data collected.
