Fly-tippers have deposited a mountain of waste in a rural area in Oxfordshire.
The "environmental catastrophe developing in full view" is approximately 150m (490ft) extending and 6m (20ft) tall.
The enormous mound has been discovered in a open area alongside the River Cherwell close to Kidlington.
Parliament representative highlighted the issue in parliament, saying it was "posing risk of an environmental emergency".
Conservation group said the unauthorized garbage pile was established approximately a recently by an criminal network.
"This is an environmental crisis taking place in full view.
"Each day that goes by elevates the threat of poisonous seepage getting into the river system, polluting animals and putting at risk the wellbeing of the entire river basin.
"The Environment Agency must act immediately, not in the distant future, which is their typical action timeframe."
Access ban had been put in place by the environmental authorities.
It is difficult to identify any specific items of garbage as it seems to have been pulverized with soil mixed in.
Part of the waste from the peak of the heap has collapsed and is now merely five metres from the waterway.
The River Cherwell is a feeder stream of the River Thames, which indicates it runs through Oxford before joining the Thames.
Government broadcast
The representative petitioned the government for assistance to eliminate the unauthorized dump before it caused a inferno or was carried into the river system.
Addressing MPs on this week, he declared: "Illegal operators have dumped a massive amount of unlawful plastic waste... weighing hundreds of tonnes, in my electoral area on a floodplain adjacent to the River Cherwell.
"Water heights are growing and thermal imaging show that the waste is also heating up, raising the threat of combustion.
"The Environment Agency stated it has inadequate capabilities for regulation, that the anticipated expense of clearance is greater than the whole annual budget of the municipal authority."
Environment minister stated the government had taken over a failing waste industry that had caused an "widespread problem of unauthorized fly-tipping".
She informed representatives the organization had issued a prohibition notice to stop more admission to the area.
In a announcement, the authority confirmed it was examining the matter and appealed for evidence.
It said: "We understand the citizens' concern about occurrences like this, which is why we take action against those culpable for waste crime."
A recent report found initiatives to tackle serious waste crime have been "critically neglected" despite the situation becoming larger and more advanced.
Government advisors proposed an autonomous "thorough" investigation into how "widespread" illegal dumping is dealt with.
