THE Environment Agency is investigating the death of 2,600 fish in a brook.

Last week The Comet reported how the Environment Agency (EA) had been alerted by concerned residents that the Pix Brook, which runs through Letchworth GC and Stotfold, had been contaminated.

The EA carried out a biological survey on the day the incident was reported.

A spokesman for the EA said: "The results show there is sewage effluence in the river. We have found the source and we are investigating and putting together a case with a view to taking action."

The EA refused to confirm who was responsible for the pollution, but said 2,600 fish had been found dead.

When The Comet approached Anglian Water, which runs Letchworth Sewage Treatment Works, a spokesman said: "We are investigating the cause of the incident and have worked closely with the Environment Agency to assist with the clean-up.

"The river is in excellent condition which means the watercourse itself has recovered quickly and there is minimal environmental impact.

"We will also be working with the Environment Agency to ensure the river is restocked with fish, which will happen in the very near future.
