Peachgrove Road

The Peachgrove Road site was established in November 1997 as the main PM10 monitoring station which also included meteorological data. From February 2003, benzene was also monitored. The PM10 monitoring station was decommissioned in October 2013 but benzene continues to be monitored at this location.

The Peachgrove Road site is approximately 80m north of the intersection of Peachgrove and Ruakura roads. From November 1997 to October 2013 Hamilton’s main PM10 monitoring station was on a property here owned by Mighty River Power. A TEOM was used to monitor PM10 (with gravimetric correction of the data) and meteorological data was also collected. The monitoring station was removed in October 2013 due to the sale of the property. A Countdown supermarket is now here. NOx, CO and O3 have all been monitored for short term survey periods. Results of this monitoring are available from Waikato Regional Council on request. Since February 2003, benzene, ethyl-benzene, toluene and xylenes (BTEX) have been monitored on a 3 monthly basis using passive 3M desorption badges on the roadside next to the decomissioned PM10 monitoring station.

    What do the dashboard colours mean for PM10?

    The dashboard colours show how PM10 levels sit in relation to the guideline – from green (less than 10%) to red (more than 100% of the guideline).  The guideline (100%) value for the daily average PM10 is 50 µg/m3 and  20 µg/m3  for the annual average.  There are no guidelines for hourly or monthly data (charcoal colour).

    What is this graph showing me?

    This graph shows how levels of PM10 change on an hourly, daily, monthly or annual basis for the selected time period. The levels depend on local sources of emissions and what the weather is doing.  Emissions from various sources change, depending on whether it’s a weekday or the weekend or at different times of the year (e.g. emissions from home heating goes up in the cold winter months).  Still conditions often lead to high concentrations, as there is no wind to blow away the pollutants in the air.   The PM10 concentrations are shown against the guidelines for air quality (for daily and annual averages), and where concentrations exceed the guideline (red line) this can be a cause for concern, especially if this occurs on a frequent basis. 

    Exceedance data (when available) shows the number of days per year that the concentrations went above 100% of the air quality guideline.  

    For information about allowable exceedances and targets, and the limitations of data shown, see the Factsheet on monitoring air quality in New Zealand.

    What do the dashboard colours mean for benzene?

    The dashboard colours show how benzene levels sit in relation to the guideline - from green (less than 10%) to red (over the guideline).  The guideline for annual average benzene is 3.6 µg/m3.  There are no guidelines for hourly, daily, or monthly data for benzene (charcoal colour) and generally monitoring is for a three month period to get an annual average.
