River Blackwater pollution discharge halted

The Environment Agency said its was concentrating on preventing any more fish deaths
A discharge of effluent into a Surrey river which killed more than 100 fish has been stopped, according to the Environment Agency (EA).
Members of the public reported seeing the dead fish on the 2km (1.2 mile) stretch of the River Blackwater in Camberley on Friday.
The EA is at the scene investigating the cause, advising on the clean up and helping to mitigate its impact.
"It is too early yet to say what the cause is," said spokesman Neil Martin.
"But we are confident that we've stopped the particular discharge."
Biology surveys
Mr Martin said liquid effluent with low oxygen levels was discharged into the river, affecting the stretch between Camberley and Sandhurst in the Shepherds Meadow area.
Such effluent could come from sewage or industrial processes, he said.
"Our focus has been on monitoring the situation over the weekend and trying to increase the oxygen levels to save fish and protect the impact further downstream.
"We will be doing some biology surveys looking at the insect life over the next couple of days to see if there has been any further impact beyond the fish that were killed."
The EA is continuing to investigate the source of the pollution.
