Coillte has confirmed that over 600 tonnes of industrial waste has been found illegally dumped at one of its forests in Co Meath.

The large scale dumping was discovered last Tuesday in Drumgill.

In a statement Coillte said it "takes the issue of dumping extremely seriously".

It says illegal dumping of any kind will not be tolerated and it is working closely with gardaí and local authorities to ensure offenders will be prosecuted.

Coillte has spent over €2 million nationally in the last five years in clean-up operations of disposing of illegal waste dumped in our forests.

Coillte said such dumping "causes serious problems to habitats, species, waters, soils and human health" and it can lead to the pollution of rivers and drinking water sources.

It also said this illegal activity can damage biodiversity and is a threat to both the people who live in an area as well as recreational users.

Anyone who sees illegal dumping taking place is asked to report it to the local authority or contact Coillte via a confidential forest security hotline on  1890 800 455.
