Residents have concerns the rubbish and off-road vehicles at the far eastern end of Helena Valley Road are destroying bushland and riparian areas that locals have worked so hard to preserve.
Amongst the rubbish are couches, televisions, car parts; even pornographic images and sex toys.
Helena Valley resident Kristy Goodchild lives close to the site and said enough is enough.
‘I think I’ve made around 10 phone calls regarding this issue,’ she said.
‘Nothing has ever been collected in the last six months.
‘More and more rubbish is being dumped in a water catchment zone; it is a disgrace, a health hazard and pure laziness on behalf of the people dumping.’
Department of Parks and Wildlife, who manage the land, confirmed the site was under investigation and evidence was being recovered from the debris.
‘That would explain why the rubbish is still there,’ a spokeswoman said.
The issue of illegal dumping is a continuing problem for the Hills area.
The Department of Environmental Regulation told Hills Gazette that areas of State forest and national park adjoining the metropolitan area, like those in the shires of Kalamunda and Mundaring, were dumping hotspots.
A spokeswoman said there were seven reports of illegal dumping across those shires in the past 12 months.
‘Parks and Wildlife works with the DER, the Keep Australia Beautiful Council and Water Corporation to investigate illegal dumping, resulting in the successful prosecution of a number of offenders,’ she said.
Sites with harmful substances such as asbestos are the ones cleaned first.
