Reality renovation show The Block Glasshouse has been called out for apparently faking a site visit from the Environment Protection Authority on one of its top-rating episodes.

The Channel Nine program originally claimed to have used an EPA representative to check on the safety of its Melbourne renovation site after a possible soil contamination issue was discovered.

However, an investigation by the Stonnington Leader has revealed the EPA had no involvement in the visit at all.

According to the Leader, an EPA representative said the group had not paid a visit to the site in question for at least 10 years.

In the show, foreman Keith Schleiger was shown requesting an EPA representative to investigate the alarming discovery of nearly 15,000 litres of fuel underneath The Block Glasshouse site.

The representative – identified only as ‘Chris’ – was reportedly an environmental scientist not directly affiliated with the EPA.

Nine spokesman Terry Stuart told the Herald Sun the confusion was the result of an “editing error”.

“He was, in fact, an environmental scientist hired by The Block Glasshouse to help us liaise with the EPA,” Mr Stuart said.

In the episode, Chris appears to take a soil sample from the site for testing which leads to the removal of fuel from the site.

“We’re basically sitting on a bomb,” Mr Schleiger said at the time.
