- The US Environmental Protection Agency (EPA) encourages state and local air monitoring groups to conduct short-term multi-site pollutant monitoring studies using non-reference method, small portable samplers.
- The concept is to “saturate” an area with easily deployed, inexpensive filter samplers, to assess air quality in areas with high concentrations of pollutants or at reclamation sites. BGI has brought this approach to its ultimate development with the addition of a true 5 liter per minute (LPM) inlet.
- The additional data acquired using saturation samplers helps air pollution control agencies to evaluate their monitoring networks consistent with requirements in 40 CFR Part 58.
