Endocrine Disrupting Compounds in the Chesapeake

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

WaterAlert

The U.S. Geological Survey WaterAlert service sends e-mail or text (SMS) messages when certain parameters, as measured by a USGS real-time data-collection station, exceed user-definable thresholds. The development and maintenance of the WaterAlert system is supported by the USGS and its partners, including numerous federal, state, and local agencies.

How We Monitor Stream Temperature in the Delaware River Basin

The USGS has been monitoring stream temperature in the Delaware River Basin since 1901, and has amassed over 650,000 daily temperature measurements. This data visualization story explores temporal and locational patterns in stream temperature observations, and how spatial variability and data gaps add complexity to prediction efforts.

Water science and management in the Delaware River Basin (data visualization story)

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.

New Jersey Coastal Plain Water-Table

The series of surficial aquifer studies were completed to evaluate the unconfined aquifer system of the NJ Coastal Plain for use as a potential source of water. As the demand for water in the State increases and the restrictions continue on the use of water from certain confined aquifers, withdrawals on the unconfined aquifer system are expected to increase.

National Water Information System (NWIS) Mapper - New Jersey

National Water Information System Web Mapper (NWISWeb Mapper) Provides access to water-resources data collected throughout the state of New Jersey as presented in the form of an interactive map.

New Jersey Flood Inundation Mapper

The USGS Flood Inundation Mapping Program (FIM) partners with local communities and other government agencies to develop and validate flood inundation map libraries. Click the title above to visit the USGS FIM website and learn more about available tools. Completed projects are collected on the USGS National Flood Inundation Mapper, brought to you by the USGS Wisconsin Internet Mapping Group

Water-Quality Changes in the Nation's Streams and Rivers

The trends mapper provides results from the largest-ever assessment of water-quality changes in the Nation's streams and rivers. More than 185 million water-quality records from over 600 Federal, State, Tribal, and local organizations were screened as part of this assessment.   

The mapper shows stream trends in water chemistry and aquatic ecology for four time periods from 1972-2012.
