The unidentified odour in Bromley has been a longstanding issue for the community, and one which has remained complex to investigate. We have a long history of working with Environment Canterbury to try and locate the sources and trial different approaches.
The Bromley residential area is close to an industrial area with a number of businesses involved in activities such as fish processing, fibreglass manufacture, composting and waste processing and wastewater treatment facilities. The estuary and tidal mudflats are adjacent and border the industrial area.
Getting the evidence to take action around odour is not a simple task due to the number of potential variables involved – including multiple sources of odour, wind, weather, temperature, time, distance and topography.
A 2018 study found that of more than 200 businesses in Bromley, about 60 are potential sources of odour, including Council-owned facilities run by Living Earth, the composting operation, and the EcoCentral-run EcoDrop the transfer station.
Smelt-It app pilot study
In March 2020, Environment Canterbury carried out a pilot study that focused on finding the causes of the long-standing odour issues in Bromley.
It involved involving residents’ reporting incidents of odour via a ‘Smelt-It’ mobile app(external link).
Resident reports were then compared to weather conditions and onsite observations by Environment Canterbury warranted officers and an independent odour assessor, as well as operational data from the Living Earth and EcoDrop facilities.
Environment Canterbury said the pilot study findings (external link)clearly identify the two Council-run facilities as significant odour emitters.
