Caroline, who reported the incident the Environment Agency said: “It was that way for over an hour, and the water water had been green/grey all day.”
Alice Hazeldine reported that her husband had reported the incident to the Environment Agency yesterday.
“Last Week he saw a lot more fish! The river is clean because there is a kingfisher. Whatever it may be, it could kill the fish. It’s unbelievable that an idiot could have poisoned our beautiful river.
Alan Brierley stated that there were otters in the river a few weeks ago. This is terrible. The culprits must be tracked down and prosecuted to the full extent allowed by law. Disgraceful.”
Keith Martin, Penwortham Councillor said: “It could have been something that has been down a roadwayside drain. Many road drains will eventually run to a watercourse. It is a crime to put anything down them.
Some people claimed that the foam resembled shaving foam or bubble bath.
A spokesperson for Environment Agency said that the agency would like to thank the public who raised concerns about pollution in the River Lostock near Preston.
