Those living and working in Welwyn Hatfield can now sign up to an alert service which sends text or email notifications when the levels of air pollution in the area increase to a moderate level or above. Two sites in North Mymms are continually monitored to check air quality.

Alerts are sent out before moderate, high, or very high levels of air pollution are forecast. According to WHBC the air quality in the borough is currently good.

Welwyn Hatfield Borough Council (WHBC) is part of the Hertfordshire and Bedfordshire Air Pollution Monitoring Network.

There are two monitors in North Mymms, one along Travellers Lane and the other close to the Great North Road (A1000) at Bell Bar.

The system uses diffusion tubes to monitor nitrogen dioxide at 29 locations across the borough, shown in the document below. All monitoring data can be found on the Hertfordshire & Bedfordshire Air Quality website. You can download all Welwyn Hatfield data, create a graph of pollution records from selected monitoring stations, and study a map of the area showing all active monitors.

Registering for the alert service is free of charge.  The service is provided by Ricardo Energy and Environment.
