EPA has been monitoring odour from the Hallam Road landfill after receiving reports from local residents. We have been: 

  • surveying the site for odour  
  • responding to pollution reports  
  • inspecting the site for compliance.  

Air quality monitoring

We conducted air quality sampling at residences near the landfill in February 2021. We tested for compounds commonly linked with odour. This includes volatile organic compounds (VOCs) and reduced sulfur compounds. Except for very low  levels of Freon 11 and Freon 12, all analysed compounds were below detection limits. We found:

  • less than 0.1 parts per billion sulfur compounds
  • between 1 and 9 parts per billion VOCs.

Freon 11 and Freon 12 are commonly occurring refrigerants. We find them in samples like this, as they are common in the atmosphere.

All levels were lower than that associated with harm to human health. Some odour may still impact residents. This is because the human nose can smell some of these compounds at levels well below those measured. 

EPA has received fewer reports of odour following the spike in October and November 2020.

Health impacts from the Hallam Road landfill  

We have commissioned studies into the health impacts of living near landfills like the one in Hallam Road. The three studies have confirmed that living near putrescible landfills do not have adverse health outcomes. Putrescible means food or garden waste. 

Odours can make it unpleasant to go outside or open windows. The more often, strong and ongoing an odour is, the more it can impact the community. 

If you feel ill from odour, contact a health professional.
