ET help Leominster to enjoy improved air quality

ET supplied a new air quality monitoring system to assist Leominster in improving air quality, helping the council collect data to identify potential remedial actions.


Herefordshire has two Air Quality Management Areas (AQMAs) due to higher levels of nitrogen dioxide, exceeding national standards (40μg/m3). ET has supplied a new Air Quality Monitoring Station in Bargates, Leominster to help mitigate the problem.

The work included all project management, installation & commissioning, together with a 3-year fully inclusive service and data collection contract.

The station will provide the council with real-time data of NO2 levels, PM10 and PM2.5 which can help identify actions to improve air quality and provide additional data on other pollutants.

This work follows ET’s upgrade of an existing automatic monitoring station on Victoria Street in Hereford last year.

By allowing more accurate measuring of air pollution, the new monitoring station will help us to identify areas of concern, improve the success rate of grant submissions, and ensure there is robust data on which to base medium to long term decisions and assess the impacts of our various initiatives.
