R package to conduct environmental justice screening analyses using data from EJSCREEN

Earlier this year, I co-authored a R package related to environmental justice (EJ) with two colleagues at US EPA (Morgan Teachey in the Office of Water and Adam Theising in the Office of Chemical Safety and Pollution Prevention). The package, hosted on EPA’s github repository, streamlines initial screening-level analyses and enables EPA staff to efficiently study multiple locations of interest. The package, EJSCREENbatch, leverages national demographic and environmental data made available by EJSCREEN, a mapping and screening tool maintained by EPA.

​An important feature of our package is that we improve upon the way EJ screening is performed by introducing a water-specific focus: we allow users to examine EJ characteristics in areas up- or downstream of a particular location by integrating data from the national hydrography dataset (NHD). The package has garnered a substantial amount of interest within the Office of Water and has already been used by several sub-offices as part of their EJ screening analyses.

The tool is currently available as a downloadable package. I am currently working on transitioning it to an interactive web interface.
