Illegal dumpers have deposited a mountain of rubbish in a open space in Oxfordshire.
The "environmental catastrophe occurring in full view" is up to 150m (490ft) in length and 6m (20ft) tall.
The huge pile has appeared in a plot of land next to the River Cherwell near Kidlington.
Parliament representative highlighted the issue in parliament, declaring it was "threatening an environmental disaster".
Protection organization stated the unlawful waste site was established around a few weeks back by an criminal network.
"This constitutes an ecological disaster taking place in plain sight.
"Every day that passes increases the risk of hazardous drainage reaching the aquatic network, polluting fauna and threatening the condition of the complete watershed.
"Regulatory bodies must respond now, not in extended periods, which is their typical response period."
A restriction order had been implemented by the environmental authorities.
It is hard to identify any specific items of waste as it appears to have been shredded with soil blended.
Some of the rubbish from the peak of the pile has collapsed and is now just five feet from the stream.
The River Cherwell is a feeder stream of the River Thames, which signifies it flows through Oxford before meeting the Thames.

The representative petitioned the authorities for assistance to remove the unauthorized dump before it caused a blaze or was washed away into the aquatic system.
Informing MPs on Thursday, he declared: "Illegal operators have deposited a massive amount of unlawful polymer rubbish... weighing substantial weight, in my constituency on a floodplain next to the River Cherwell.
"Water heights are growing and heatmaps show that the garbage is also heating up, elevating the risk of fire.
"The Environment Agency stated it has limited capabilities for compliance, that the anticipated price of clearance is greater than the whole yearly funding of the regional government."
Cabinet member said the government had taken over a failing waste industry that had created an "widespread problem of unauthorized fly-tipping".
She advised representatives the organization had issued a access ban to stop more entry to the area.
In a announcement, the authority confirmed it was investigating the incident and asked for evidence.
It commented: "We acknowledge the citizens' frustration about occurrences like this, which is why we take action against those accountable for illegal dumping."
A newly released study determined initiatives to address significant illegal dumping have been "critically neglected" even though the problem developing into larger and more advanced.
Government advisors proposed an independent "thorough" examination into how "prevalent" illegal dumping is tackled.
