Assessing Odour Effects at a Landfill

MWH Global was commissioned by the Horowhenua District Council (HDC) to undertake an odour impact assessment for the landfill located in Levin, Manawatu-Wanganui, New Zealand.

This study evaluates the potential odour effects that may arise during the operation of the landfill using a variety of methodologies and techniques, which enabled the principal emission sources at the landfill to be identified and assessed.

This study reviews the recent odour complaints record for the site and identifies a number of potential adverse impacts associated with the operation of the landfill. A number of mitigation measures are recommended to reduce the likelihood of further odour nuisance effects arising in the surrounding community.
