THE cause and source of a potential pollution leak that killed a number of trout in a Greenfield stream in 2018 will remain a mystery.
Twelve months after the Independent first highlighted the incident at Warlow Brook, the Environment Agency has closed its investigation without finding any answers.
At the time we were told: “Approximately 200m of a tributary of Chew Brook has been impacted, resulting in several dead trout.
“Environment Officers have taken water samples from various outlets to identify the potential pollutant.”
An Environment Agency spokesperson now confirmed: “The Environment Agency attended Chew Brook, last year, following reports of dead fish.
“We took water samples for testing but no cause was identified. We would like to take this opportunity to thank the public who call our hotline 0800 80 70 60 to report environmental issues.”
