The USGS-NNSS Regional Groundwater Explorer is a web-based application developed by the USGS, in cooperation with DOE. The application provides access to a comprehensive database of groundwater levels, hydrologic conditions, construction, and descriptive narratives for wells on and adjacent to the NNSS. The Groundwater Explorer is designed to be a user-friendly and interactive application for data exploration and retrieval. The application contains interactive network maps, additive filters to narrow searches, and hydrographs with comparative tools. Detailed reports can be generated for all wells of interest, and their associated data tables can be exported for use outside of the web-based application.
