had swept the material outside his shed, his children played and built sandcastles in mud contaminated with uranium. Another significant controversy over Ranger's environmental impact is the public legal confrontation over releases into Magela Creek in the 1995 wet season. More recently, the ARRAC report from 2002 details a major leak of about 2 megalitres of potentially polluted water, over a number of months. In 2007, water breached a retention pond, overflowing back into the pit. The original authorisation required that this water be contained at all times. In 2006, water management systems were disrupted by Cyclone Monica. In May 2010, it was reported that a tailings dam may have released millions of litres of radioactive water into world heritage-listed wetlands in Kakadu National Park, home to about 500 Aboriginal people. In November 2013, four drums previously used to transport yellowcake were found in a rural area of Darwin. The company recovered the drums amid concerns about the potential spread of radioactive contamination. On 7 December 2013 there was an incident at a mine site inside Kakadu National Park, with about a million litres of slurry, comprising crushed ore and acid, believed spilled, workers evacuated and production shut down. A leaching tank containing the slurry burst at about 1am. The spilled material was entirely contained within the safety bunds and no material leaked into the wider ecosystem.
