Near-Real-Time and Laboratory Data by State
The map below provides links to RadNet individual air monitoring location webpages. Data are shown as graphs and tables that are updated as new data becomes available. Searchable current and historical monitoring data are available in the RadNet database in EPA's Central Data Exchange (CDX). To download all available near-real-time time data for a RadNet stationary air monitoring location, visit the RadNet CSV File Downloads webpage.
Below the map is a list, organized by state, of RadNet stationary air monitoring locations, as well as precipitation and drinking water sampling locations that reported data in 2020.
