This layer displays the percentage of days with concetrations of ozone matter above the National Ambient Air Quality Standard (NAAQS) of 35.0 micrograms per cubic meter.
This indicator displays changes in the number of days with unusually (>95th percentile) cold temperatures in the contiguous 48 United States. Indicator data are acquired from the EPA’s Climate Change Indicators in the United States, Fourth Edition, published in 2016.
This indicator describes trends in average surface temperature for the United States. Indicator data are acquired from the EPA’s Climate Change Indicators in the United States, Fourth Edition, published in 2016.
This indicator examines changes in the size and frequency of inland river flood events in the United States. Indicator data are acquired from the EPA’s Climate Change Indicators in the United States, Fourth Edition, published in 2016.
This indicator examines changes in total snowfall in the contiguous 48 United States. Indicator data are acquired from the EPA’s Climate Change Indicators in the United States, Fourth Edition, published in 2016.
This layer displays the daily average concentration of fine particulate matter and the percentage of days with concetrations of fine particulate matter above the National Ambient Air Quality Standard (NAAQS) of 35.0 micrograms per cubic meter in 2014.
This layer displays the daily average concentration of ozone and the percentage of days with concetrations of ozone above the National Ambient Air Quality Standard (NAAQS) of 0.075 parts per million in 2014.
Layer displays the modelled cancer risk associated with air toxics exposure. Figures represents the liklihood of hazardous exposure per 1 million population.
Layer displays the modelled non-cancer risk associated with air toxics exposure. A hazard index (HI) of 1 or lower means air toxics are unlikely to cause adverse noncancer health effects over a lifetime of exposure.
This layer displays the locations of the Environmental Protection Agency (EPA) Assessment, Cleanup and Redevelopment Exchange System (ACRES) sites. ACRES stores information reported by EPA Brownfields grant recipients on brownfields properties assessed or cleaned up with grant funding as well … Continued
