Farm slurry polluted a stream leading to bathing water last month

Ceredigion County Council said test results on water at Llangrannog showed no further trace of contamination.

The local authority and the Environment Agency were alerted to the scare at the end of last month.

The council put up signs warning people about the pollution, but removed them on Wednesday night.

The slurry had seeped into a stream leading to the beach.

Dewi Roberts, principal environmental health officer at the council's environmental protection unit, said: "We took some samples on Monday and the results came out alright.

"We removed the notices warning bathers last night (Wednesday).

Although the council put up some signs warning of the problem, people still bathed in the sea Dewi Roberts

"The results of tests on the stream during the last few weeks weren't that good, but the sea water hadn't been a problem.

"The sea water had always attained the minimum standard required."

Mr Roberts added: "Although the council put up some signs warning of the problem, people still bathed in the sea.

"That wasn't a problem because the standard of the sea water was never an issue."

There has been daily bacteriological sampling of the water at Llangrannog.

The Environment Agency said it was compiling a report about the slurry spill and that would be passed to its legal team which would take the appropriate action.

This isn't the first pollution problem that's affected the beach.

In December last year, an investigation was launched to try to find out why it was the only one in Wales to fall below European standards.

It is considered one of the most popular beaches along the Cardigan Bay coastline, but contamination of the water led to it falling to achieve EU mandatory standards.
