Hove MP Mike Weatherley has asked the Environment Secretary about the quality of seawater locally after concerns were raised with him by constituents.
Mr Weatherley has written to his fellow Conservative, Owen Paterson, who heads the Department for Environment, Food and Rural Affairs.
He said: “A number of concerns have been raised with me about the quality of the water.
“Particular worries have been voiced over the level of pollution and its causes.
“I understand that storms have a considerable impact on the quality of water within a specific area and, while sewage may not be an issue from Brighton and Hove, pollution from the neighbouring conurbations may be an important factor, including from the River Adur.
“As well as these specific issues, I am interested in the general fish stock off the coast of Brighton and Hove as well as the cleanliness of the beaches themselves.”
He added: “The sea is one of Brighton and Hove’s greatest assets so I was naturally concerned when issues surrounding the quality of the water were raised with me.
“I hope that the Department for Environment, Food and Rural Affairs will be able to clarify the current state of affairs and provide residents with assurances that the long-term protection of our local seawater is a priority.”
