EPA Office of Water (OW): STORET Water Quality Monitoring Stations NHDPlus Indexed Dataset

Metadata Updated: August 9, 2017

Storage and Retrieval for Water Quality Data (STORET and the Water Quality Exchange, WQX) defines the methods and the data systems by which EPA compiles monitoring data (typically water quality data, but not exclusively water quality data) that are collected by a number of entities. This dataset represents the monitoring locations contained within the STORET Data Warehouse, or put another way, the point locations of where data providers to the STORET Data Warehouse have performed water monitoring activities such as water sampling or taking field measurements. This dataset provides the NHDPlus georeferenced monitoring locations. These locations have been QA'd based on predetermined accuracy criteria (see process steps below), and then georeferenced to NHDPlus v2.1 per a predetermined method (see process steps below).
