National Ground-Water Monitoring Network: Groundwater Monitoring Database

The National Ground-Water Monitoring Network (NGWMN) is a comprehensive mapping and data portal that provides access to groundwater monitoring information across the United States. This interactive web application allows users to explore over 20,000 monitoring sites that track both water levels and water quality parameters from wells and springs nationwide. Users can filter and customize their data view through multiple criteria including principal aquifer systems (from Ada-Vamoosa to Wyoming's various geological formations), available data types (water level, water quality, or well logs), site types (wells vs. springs), geographic locations by state and county, contributing agencies (ranging from state geological surveys to federal organizations like the U.S. Geological Survey), and aquifer characteristics such as lithology (rock types from carbonate to unconsolidated sediments) and confinement status. The application serves as a centralized hub for accessing critical groundwater data collected by various federal, state, and local agencies, supporting water resource management, research, and policy decisions by providing both current monitoring status and historical trends for groundwater systems across diverse geological settings throughout the country.RetryY
