Two individuals have been detained as a component of an inquiry into the dumping of many thousands of tonnes of refuse in a field in the county of Oxfordshire.
Officials reported that a 69-year-old was detained at a property in Andover, Hampshire, while a 54-year-old was detained in Slough in association with the massive pile of garbage tipped near Kidlington.
These detentions occur a week after a previous investigation which revealed the operation of more than 500 illegal dumps across England, including at a minimum of 11 so-called "super sites" greater than 20,000 metric tons.
A spokeswoman for the environment body stated that the apprehensions were for environmental and proceeds of crime violations and were a "key step" in continuing investigations. The two individuals have been set free on conditional release.
The dump in the Kidlington area, positioned between the River Cherwell and the A34 road, is believed to hold about 21,000 tonnes of waste in a mound which is up to 150m (490ft) in length and 6m (20ft) tall.
This mound of garbage is composed of what seems to be processed residential waste, fragmented plastics, polystyrene, tyres and other everyday items.
It is just a single of 517 unauthorized dumps across England, at least 11 of which are estimated to hold more than 20,000 tons of rubbish. They feature a 280,000-tonne location in Cheshire, two 50,000-tonne sites in Lancashire county and Cornwall and a 36,000-tonne tip in the county of Kent.
The total number of such major dumps is probably to be higher, as the environment authority has in the past stated it does not hold data on weight for each illegal site.
The majority sites are in rural settings, frequently concealed, and on land that is intended to be farm property.
Law enforcement say numerous are run by organized crime groups, who are making cash by charging significantly less than lawful operators to accept and dispose of rubbish.
Businesses have to pay disposal fees to use licensed waste facilities, contingent on the amount and nature of material they are trying to get rid of, and a waste tax is also applied at just over £126 per tonne.
Preparatory operations to clean up the affected site started in recent weeks following worries over the potential of blaze and the effect that would have on the adjacent major road.
A commercial clean-up company has been awarded the task to remediate the area over the next 12 months at a cost of £9.6m.
An compliance manager for the country's environment division commented that the agency would be aiming to recover the remediation costs under asset recovery legislation from any individual successfully prosecuted at the conclusion of its current inquiry.
She further stated that the recent apprehensions would help "push the probe forward" and permit officials to "pursue more lines of inquiry to determine in detail what occurred and who was implicated".
"The illegal dump at the site was an atrocious and deliberate affront on our environment and we share the community's anger at this egregious act," she remarked.
A senior official welcomed the actions, commenting: "This unauthorized tipping of garbage at this location is appalling and has resulted in considerable harm to the ecology and anguish to the surrounding residents.
"Our government is pledged to stamping out this category of illegal activity in the nation, by increasing funds to tackle environmental crime, employing more staff and enacting tougher controls and penalties for those who flout the regulations."
The apprehensions were carried out on a recent Thursday by personnel from a regional crime unit and follow an earlier detention of a man in his thirties from the Surrey region in November. He was set free pending additional enquiries.
