Air Quality

The Town of Goderich recently purchased an Air Quality sensor that measures the air quality in Goderich and uploads the information in real-time to several sites which then map the information.  

The Town's sensor indicates the Air Quality Index for Goderich.   The Air Quality Index (AQI) is based on air quality standards and takes into consideration both environmental and human health concerns.  It reports current air quality based on a specific level of an individual air pollutant.   The AQI is based on the scale of 0 to 500.  

Below is the real-time map as seen at PurpleAir or


Air Quality Health Index vs. Air Quality Index 

The Air Quality Health Index (AQHI) is a health protection tool that is designed to help you make decisions to protect your health by limiting short-term exposure to air pollution and adjusting your activity levels during increased levels of pollution.  This index uses a scale from 1 to 10 and is communicated to the public through Environment Canada weather reports.  

For more information on the Air Quality Health Index and the Air Quality Index visit AQHI Ontario.
