Analysis of Toxics Release Inventory Data from the US Environmental Protection Agency
The US Environmental Protection Agency makes much of its data available to the US public. Of this data, one of the most interesting is their "Toxics Release Inventory" (TRI). This inventory is an method of tracking the toxic waste management processes and amounts in US facilities. Data is reported annually by individual facilities. Chemicals that are required to be reported are generally those that cause:
- Cancer or other chronic human health effects
- Significant adverse acute human health effects
- Significant adverse environmental effects
This repository contains:
- The original TRI data used in the analysis ("Datasets" Folder)
- The reports and figures generated for the original project ("Final Project Documents")
- Originally focused on clustering and PCA for the facilities that report to the EPA
- The R scripts/modules, shapefiles, cleaned data, and images used for the Shiny App ("AppFiles")
- The main focus of this repo
- Shapefiles include .dbf, .prj, .shx, .shp files
- "Data Prep For App" file shows many tests and processes for cleaning data and exploring visualization methods
- "AppFiles" contains the most recent app files including data, modules, and the core app script
This originally started as a final project for an Exploratory Data Analysis course (STAT 442) at South Dakota State University. However, since then it has narrowed its focus to the Shiny App, now called ToxOnline, and seen many improvements, including better functionality, user friendliness, and advanced features. Now it serves as a fully operational environmental data analysis tool.
