Invercargill and Gore are now both in breach of the Government’s National Environment Standards for Air Quality (NES), despite being only two months into the winter monitoring period.
Invercargill recorded its sixth exceedance on Friday 1 July of 56 micrograms/m3, while Gore registered its third on Thursday 30 June, recording 55 micrograms/m3. Friday also saw Winton record its first exceedance since 2008, with 53 micrograms/m3. While Winton is not a gazetted airshed, Environment Southland has been monitoring air quality there periodically since 2006.
Environment Southland air quality scientist Owen West said the results were disappointing, especially with so much of the winter period ahead but the recent still and calm weather conditions were likely contributing factors.
