Masterton

Masterton is located near the head of the inland Wairarapa valley plain bounded by hills and ranges either side. The Masterton urban airshed is the least windy and has a greater temperature range than other parts of the region.

Air quality is currently monitored at two sites surrounded by residential land; one in Masterton West on Pownall Street and one in Masterton East on Herbert Street. 

The Masterton East monitoring site is used to determine compliance with the National Environmental Standard for PM10. The Standard requires Masterton to have no more than three days per year where PM10 levels are above 50 µg/m3 from September 2016 and no more than one day per year from 2020.

The Masterton District Council is currently working with the local community on a social change programme to reduce wood burner emissions and improve in-home energy efficiency. This programme aims to improve air quality to meet the National Standard and to benefit public health.

 

Town Summary
Air quality in this town

In Masterton PM10 and PM2.5 levels are highest during winter evenings when people are using  fires for home heating and when weather conditions are cold, there is little wind and skies are cloudless. Other sources of PM10 and PM2.5 emissions are traffic, industrial and commercial processes and natural sources.

    The table shows the proportions of the main sources of PM10 in this town from home heating, industrial activities, outdoor burning and traffic.  (Indoor sources and natural sources of air pollutants are not included in this breakdown). 

    These values come from 2013 data sourced from MfE’s data service.  Consistent methodology was used to calculate these estimates of PM10 emissions, which allows comparison between towns throughout New Zealand.  Some regional council published emissions information might differ if they were prepared in a different year or used another method. Contact your regional council for more information about PM10 and other emissions.

What is this graph showing me?

The graph shows the monthly average PM10 concentration at one representative site in this town for the year selected. In many towns in New Zealand, PM10 peaks in the winter when air temperatures and wind speeds are lowest as more people heat their homes during colder weather, and still conditions mean that there is no wind to disperse the air pollutants.
