During a National Water Quality Network (NWQN) sampling trip in May to the St Lawrence River, Hydrologic Technician Dave Knauer finds a batch of Zebra mussels attached to the boat anchor.
Crews from the U.S. Geological Survey have been in the field for weeks measuring flooding in the Midwest and in the Mississippi River watershed, and more recently flooding and storm tides on the Northern Atlantic coast, as higher temperatures, heavy rain, snowmelt and nor’easters affected numerous states.
USGS field crews are deploying storm-tide and wave sensors today from Maine to Delaware to track and study a Nor’easter forecasted to begin tomorrow.
Delineation of Salt Water Intrusion through Use of Electromagnetic-Induction Logging: A Case Study in Southern Manhattan Island, New York
A journal article was recently published by the USGS (Stumm and Como, 2017) detailing the use of a borehole-geophysical technique using electromagnetic conductivity to delineate the depth and concentration of saltwater intrusion in Long Island's aquifer system.
The presentations below include the topics discussed at the Project Kickoff Meeting for Groundwater Sustainability of the Long Island Aquifer System
Exploratory well drilling on Long Island has begun, and is planned to continue through the summer. The drilling will better define the aquifer system, track saltwater encroachment, and inform a new groundwater-flow model for the Island.
Study Assesses Threats to Groundwater Availability and Sustainability in Northern Atlantic Coastal Plain
The U.S. Geological Survey began a multiyear regional assessment of groundwater availability in the Northern Atlantic Coastal Plain (NACP) aquifer system in 2010 as part of its ongoing regional assessments of groundwater availability of the principal aquifers of the Nation.
