The E.P.A. Air Toxics Data Archive (ATDA)
Developed a database and website system to provide online access to the EPA's air toxic and criteria pollutant data in order to facilitate analysis of the spatial patterns, temporal nature, and general characteristics of various air toxic compounds. Previously, this data had been available in different forms through two legacy websites, and access to these data was cumbersome and limited. Therefore, the VIEWS framework (described below) was leveraged and extended to provide secure and seamless access to these data through a single website and a unified set of online tools.
