Baseline Groundwater-Quality Data from a Densely Developed Coastal Neighborhood, Falmouth, Massachusetts (June 2016 - August 2024) (ver. 6.0, September 2025) Baseline Groundwater-Quality Data from a Densely Developed Coastal Neighborhood, Falmouth, Massachusetts (June 2016 - August 2024) (ver. 6.0, September 2025)
This data release provides a comprehensive dataset of sampling-site characteristics and baseline groundwater-quality data collected from a network of multilevel sampling wells installed in a densely developed coastal neighborhood undergoing a conversion from onsite septic systems to municipal sewering. The U.S. Geological Survey collected groundwater samples in Falmouth, Massachusetts...
Lakebed Groundwater and Surface-Water Temperatures on September 18, 2020, at Shubael Pond, Marstons Mills, Massachusetts Lakebed Groundwater and Surface-Water Temperatures on September 18, 2020, at Shubael Pond, Marstons Mills, Massachusetts
This data release contains lakebed groundwater and surface-water temperatures collected during a survey on September 18, 2020, by using a handheld thermocouple probe at Shubael Pond, a groundwater flow-through kettle-hole pond, located in Marstons Mills, Massachusetts. The dataset includes a comma separated values (.csv) file, a geospatial dataset (shapefile), and FGDC-compliant metadata...
Adult Shorebird Morphological Measurement Data Adult Shorebird Morphological Measurement Data
This dataset consists of five tables, 1) shorebird morphological measurements collected from various species captured from 1895-2021, 2) taxonomy, 3) contributors, 4) sampling locations, and 5) cross-reference publications. In addition, photographs of plumage patterns are available for several species. Researchers with the U.S. Geological Survey - Alaska Science Center, along with...
Data for Per- and Polyfluoroalkyl Substances (PFAS) in groundwater samples collected by the California Groundwater Ambient Monitoring and Assessment Priority Basin Project, 2019-2023 Data for Per- and Polyfluoroalkyl Substances (PFAS) in groundwater samples collected by the California Groundwater Ambient Monitoring and Assessment Priority Basin Project, 2019-2023
The California Groundwater Ambient Monitoring and Assessment Program Priority Basin Project (GAMA-PBP) analyzed for per-and polyfluoroalkyl substances (PFAS) in groundwater samples collected from domestic and public drinking water supply wells in California. GAMA-PBP is a cooperative program between the U.S. Geological Survey and the California State Water Resources Control Board. This...
Simulated Recharge Areas to Surface Waters and Public-Supply Wells with Travel Times Greater Than and Less Than 10 Years For Average 2005-2015 Conditions, Long Island, NY Simulated Recharge Areas to Surface Waters and Public-Supply Wells with Travel Times Greater Than and Less Than 10 Years For Average 2005-2015 Conditions, Long Island, NY
This data release contains model simulation results of a particle tracking analysis to delineate areas that provide recharge to surface waters and public-supply wells on Long Island, NY. The analysis partitions the recharge areas based on particle travel times of greater than or less than 10 years to reach the receiving surface water or well. The simulation was performed using a regional...
Hydraulic Conductivity and Transmissivity Estimates from Slug Tests in Wells Within the Mississippi Alluvial Plain, Arkansas and Mississippi, 2020 Hydraulic Conductivity and Transmissivity Estimates from Slug Tests in Wells Within the Mississippi Alluvial Plain, Arkansas and Mississippi, 2020
During the spring and summer of 2020, the U.S. Geological Survey, Lower Mississippi – Gulf Water Science Center, conducted single well slug tests on selected wells within the Mississippi Alluvial Plain in Arkansas and Mississippi to estimate hydraulic conductivity (K) and transmissivity (T) values for the aquifers in which the wells are screened. A total of 324 tests were conducted on 48...
