Evaluation of passive samplers for cyanotoxin detection by immunoassay and chromatographic-mass spectrometry Evaluation of passive samplers for cyanotoxin detection by immunoassay and chromatographic-mass spectrometry
Harmful algal blooms, particularly cyanobacterial harmful algal blooms, threaten aquatic ecosystems, drinking water supplies, and recreational resources. In 2019, the U.S. Geological Survey, in collaboration with the New York State Department of Environmental Conservation, deployed solid phase adsorption toxin tracking (SPATT) samplers in Seneca Lake, Owasco Lake, and Skaneateles Lake to...
The Long Island Sound and Watershed Metadata map application The Long Island Sound and Watershed Metadata map application
The Long Island Sound and its watershed encompass an area of about 17,000 square miles and include the Connecticut, Housatonic, and Thames Rivers, which all drain to the sound. Dozens of organizations from government agencies, nonprofits, and Tribal Nations have developed projects and monitoring programs to analyze and protect the water resources of the watershed and sound. The abundance...
A geospatial analysis of water-quality threats from orphan wells in principal and secondary aquifers of the United States A geospatial analysis of water-quality threats from orphan wells in principal and secondary aquifers of the United States
Throughout the history of oil and gas production in the United States, millions of wells have been drilled for exploration and energy production. Hundreds of thousands of unplugged wells are no longer actively producing and are currently under orphan status, with no responsible party obligated for plugging. Orphan wells can pose threats to water resources by providing pathways for...

Regional Assessment of Compound Flood Hazard from the Combined Effects of Coastal, Stormwater and Groundwater Emergence Flooding
Compound flooding is flooding that results from a co-occurrence of multiple flood drivers. In this project we consider precipitation (pluvial flooding, overland flow of stormwater), coastal storm surge and tidal flooding (coastal flooding), and flooding that occurs as a shallow water table intersects the land surface or critical infrastructure (groundwater emergence flooding). These flooding...
A National Predictive Model for PFAS Occurrence in Groundwater
In October of 2024, USGS Scientist’s published a study where they created a model to predict PFAS occurrence in groundwater at the depths of drinking water supplies. This model can help guide our partners to sample areas where PFAS in drinking water could be an issue for the public.

Groundwater Flow Modeling - Long Island, New York
Numerical models provide a means to synthesize existing hydrogeologic information into an internally consistent mathematical representation of a real system or process, and thus are useful tools for testing and improving conceptual models or hypotheses of groundwater flow systems. The goal of this effort is to develop a regional model for the Long Island aquifer system to simulate changes in water...
