Online maps provide a view into the groundwater resources of 10 confined aquifers beneath Central and Southern New Jersey. These large-scale water-level surveys completed every 5 years provide a regional overview of groundwater conditions and helps water resource managers identify vulnerabilities to ensure their sustainability for current and future groundwater use.

Drinking-water quality and potential exposures to per- and poly-fluoroalkyl substances (PFAS) at the point-of-use (tapwater) are a rising concern in the United States (US).

The Flood-inundation maps for 10 New Jersey counties show areas of potential coastal flooding from wind driven storm surge, allowing users to access real-time tidal elevation data from the USGS New Jersey Tide Network webpage. This information can be used to display flood-inundation maps for a range of tidal elevations to better understand areas of potential flooding. 

US Geological Survey research on contaminants in drinking water across the US.

The U.S. Geological Survey WaterAlert service provides notifications to your email or phone for changes in water conditions based on thresholds you choose.

Findings from US Geological Survey studies on sources, occurrence, effects and risk of contaminants throughout the Chesapeake Bay Watershed.

The National Water Dashboard (NWD) is a mobile, interactive tool that provides real-time information on water levels, weather, and flood forecasts - all in one place on a computer, smartphone, or other mobile device. The NWD presents real-time stream, lake and reservoir, precipitation, and groundwater data from more than 13,500 USGS observation stations across the country.

Neural networks are powerful deep learning models that help us make accurate environmental predictions. This data visualization describes how to train an artificial neural network, and how the USGS uses them to make physically-realistic predictions with less data.

During large, short-term events, the USGS collects streamflow and additional data (including storm tide, wave height, high-water marks, and additional sensor deployments) to aid in documenting flood events. The USGS Flood Event Viewer provides convenient, map-based access to downloadable event-based data.

The Delaware River supports thriving ecosystems and drinking water for 16 million people. How water is shared, and the quality of that water, has been the focus of decades of inter-state discussion, negotiation, and research. This data visualization story uses streamflow, salinity, and temperature to show how new USGS science and monitoring can inform water management in this age of cooperation.

The National Water Information System (NWIS) Mapper provides access to over 1.5 million sites contained in the USGS National Water Information System (NWIS), including sites where current and historical surface-water, groundwater, springs, and atmospheric data has been collected. Users can search by site type, data type, site number, or place.

The Water Quality Portal integrates and provides access to publicly available water-quality data from databases such as USGS NWIS and BioData, EPA STORET, and USDA-ARS STEWARDS through a single search interface.
