A new campaign group has been formed.

The Blackwater Guardians is concerned about the dissolution process that has started at Bradwell Power Station and claims it will result in unnecessary discharges of radioactive liquid being poured into the Blackwater Estuary, causing harm to people and the environment.

Magnox, the company which operates the plant, and the Environment Agency, say it is safe and has been used at other locations for years.

The Blackwater Guardians group has been formed by Mersea Islander Tracey Jones.
