Abstract

Under the requirements of the Clean Water Act, every state in the US must report to the EPA every two years on the designated uses for its waterways and whether those designated uses are being attained. These reports are summarized in the EPA ATTAINS database, and those data are publicly available through an application programming interface provided by EPA. This Hydroshare resource provides code for extracting these designated use attainment data, specifically those designated uses that are ecologically related, for two time periods: 2008 and 2022. The scripts summarize the the total number of river miles for each state and the US, collectively, that are attaining, not attaining, not assessed, or had insufficient data to report on.
