Environmental investigation findings

City of Newcastle has completed an environmental investigation at the site of an historical gasworks in Waratah. We initiated the investigation in mid-2016, after advice from the NSW Environmental Protection Authority (EPA) that a former gasworks may have operated on land bounded by Ellis, Turton and Georgetown roads.

The investigation found elevated levels of contaminants in shallow soils likely to be associated with historical gasworks at 13 properties within the eastern portion of the site, consistent with the area where former gasworks infrastructure is understood to have been located.

Results from samples collected from the western portion of the former gasworks site and the surrounding public areas found some elevated concentrations of urban contaminants; however, gasworks related contaminants were typically absent in these samples.

These urban contaminants with elevated concentrations are considered typical of background levels within the local Waratah area and reflect the long-term impacts of a range of industrial activities in the neighbourhood, including brickworks, collieries, foundries, smelters, steelworks and incinerators, as well as vehicular traffic.

We are working closely with the 13 properties identified as affected by elevated gasworks contaminants to determine remediation options for each property.

We are also advising all Newcastle residents to apply good practice and follow some basic precautions to avoid exposure to elevated urban contamination.

Precautionary recommendations

City of Newcastle is working closely with   NSW HNELHD and the  NSW EPA to address potential health and environmental concerns.

The following precautionary advice has been recommended for occupiers of residential premises, within the eastern portion of the site, to minimise potential short-term exposure risks to gasworks related substances, until this matter had been further investigated and longer-term advice provided:
  • Not eating any vegetables or fruit grown at the property or eggs laid by hens on the property
  • Avoid having areas of bare soil by maintaining grass cover or otherwise covering bare areas
  • Minimise exposure to soil during gardening activities by minimising dust generation, wearing gloves and washing hands after handling soil
  • If children are playing in sand pits or soil, it is advised that this occur in a raised bed or structure above the natural ground level. The raised bed or structure should contain sand or soil that has not been sourced from onsite so as to avoid any potential contamination.

The State has appointed Property NSW as the most appropriate agency to manage the remediation of the historic Waratah Gasworks site.
