Environmental Control Network of the Government of Castilla y León

In 1992 research began to find sites for the future air quality monitoring stations in the Community of Castilla y León, an ambitious project undertaken by Envira (Ingenieros Asesores) in order to establish a network of stations for monitoring air pollution immissions at low heights (ambient air), nowadays known as Air Quality Control Network. Thanks to the results obtained in this research, a network was established and ENVIRA has been responsible for its maintenance since 1995.

Envira currently maintains and operates the network, which implies, among other things, the following actions:

• Daily monitoring of the data collected in all the stations of the network.
• Complete maintenance of analyzers, both on-site or at the laboratory.
• On-site calibration, once every two years, of the gas analyzers by our accredited lab.
• Management of the Mobile Air quality monitoring Station.
• Survey and management of the quality system according to ISO 9001:2008.
• Surveillance and information to the public.
• Air quality evaluation.
