Following a diesel leak at Christchurch Men’s Prison, further testing of bore water has confirmed clear results, alleviating concerns of potential contamination.
The incident occurred on May 24 when approximately 14,000 litres of diesel seeped into the ground due to an open hatch on a fuel tank at the prison. This raised concerns about the impact on water supplies for neighboring properties.
Corrections custodial services commissioner Leigh Marsh reported that a recent sample taken from outside the prison perimeter on June 6 showed no signs of contamination, providing reassurance to the community.
However, a sample collected 200 meters from the prison on May 28 tested positive for dissolved hydrocarbon, prompting Corrections to advise eight affected properties to refrain from using water from their private bores for drinking or cooking until further notice. The water remains safe for non-consumption purposes such as showering and washing.
Despite the encouraging test results, Corrections continues to exercise caution by conducting ongoing testing and monitoring. Neighboring residents will be kept informed of developments and provided with necessary support to ensure access to clean water.
As part of the response plan, Corrections is implementing additional bore drilling and expanding testing sites to assess the extent of contamination and determine the next steps in collaboration with the National Public Health Service.
