Concentrations of Per- and Polyfluoroalkyl Substances (PFAS) and Other Chemical Constituents for Groundwater and Surface-Water Samples on Western Cape Cod, Massachusetts, 2014-2019 (ver. 1.1, November 2025) Concentrations of Per- and Polyfluoroalkyl Substances (PFAS) and Other Chemical Constituents for Groundwater and Surface-Water Samples on Western Cape Cod, Massachusetts, 2014-2019 (ver. 1.1, November 2025)
Groundwater, surface water, and associated quality assurance samples were collected downgradient of an abandoned fire training area and wastewater infiltration beds on western Cape Cod, Massachusetts and analyzed for per- and polyfluoroalkyl substances (PFAS) from 2014-2019. Water-quality properties measured at the time of sample collection include pH, specific conductance, temperature...
Data and Model Archive for Simulations of Seawater Restoration on Diked Salt Marshes Data and Model Archive for Simulations of Seawater Restoration on Diked Salt Marshes
This dataset and model archive provides geochemical modeling input and selected output data used in simulations of seawater restoration on historically diked salt marshes. Biogeochemical changes resulting from seawater reintroduction were simulated using the computer program PHREEQC (Parkhurst and Appelo, 2013) to help support efforts to restore tidal flow and associated estuarine...
Predictions of PFAS in groundwater used as a source of drinking water and related data in the conterminous United States Predictions of PFAS in groundwater used as a source of drinking water and related data in the conterminous United States
An extreme gradient boosting ensemble tree model predicting per- and polyfluoroalkyl substances (PFAS) occurrence in groundwater at the depths typical of the bottom of public and domestic drinking water supplies across the conterminous United States was developed. PFAS data used to train the model were collected between 2019 and 2022 by the U.S. Geological Survey National Water Quality...
Highway-Runoff Database (HRDB) Version 1.2.0 Highway-Runoff Database (HRDB) Version 1.2.0
The Highway-Runoff Database (HRDB) was developed by the U.S. Geological Survey (USGS), in cooperation with the Federal Highway Administration (FHWA) Office of Project Delivery and Environmental Review to provide planning-level information for decision makers, planners, and highway engineers to assess and mitigate possible adverse effects of highway runoff on the Nation's receiving waters...
Data and R Code to Derive Estimates of Groundwater Levels Using MOVE.1 Regression and Compute Monthly Percentiles for Select Wells in Massachusetts Data and R Code to Derive Estimates of Groundwater Levels Using MOVE.1 Regression and Compute Monthly Percentiles for Select Wells in Massachusetts
This data release contains extended estimates of daily groundwater levels and monthly percentiles at 27 short-term monitoring wells in Massachusetts. The Maintenance of Variance Extension Type 1 (MOVE.1) regression method was used to extend short-term groundwater levels at wells with less than 10 years of continuous data. This method uses groundwater level data from a correlated long...
Environmental Data in Relation to the Occurrence and Toxicity of Pseudo Nitzschia in Frenchman Bay, Maine, 2010 to 2021 Environmental Data in Relation to the Occurrence and Toxicity of Pseudo Nitzschia in Frenchman Bay, Maine, 2010 to 2021
This dataset includes CSV data files containing environmental data that may be associated with the occurrence and toxicity of the diatom Pseudo nitzschia in Frenchman Bay, Maine, that can form harmful algal blooms and produce the toxin domoic acid. The dataset covers the period 2010 through 2022 or shorter period depending on the variable. Elevated concentrations of domoic acid in Pseudo...
Geochemical Data Supporting Analysis of Fate and Transport of Nitrogen in the Nearshore Groundwater and Subterranean Estuary near East Falmouth, Massachusetts, 2015-2016 Geochemical Data Supporting Analysis of Fate and Transport of Nitrogen in the Nearshore Groundwater and Subterranean Estuary near East Falmouth, Massachusetts, 2015-2016
Geochemical data were obtained to investigate the fate and transport of nitrogen in a subterranean estuary near East Falmouth, Massachusetts. The goal of this investigation was to assess nitrogen attenuation in the aquifer under the Eel River estuary and the adjacent peninsula, introduced as inorganic nitrogen that was densely populated with residences havingfrom residential septic...
Estimating domestic self-supplied water use in Rhode Island, 2014–21 Estimating domestic self-supplied water use in Rhode Island, 2014–21
Water withdrawal from private groundwater wells is often unaccounted for in water planning studies, and water from private wells can be a source of exposure to environmental contaminants. The sizes of populations that depend on private wells for domestic water use and the amounts of water that are withdrawn from these wells are generally poorly represented in data collection efforts...

Evidence of nitrate attenuation in intertidal and subtidal groundwater in a subterranean estuary at a Cape Cod embayment, East Falmouth, Massachusetts, 2015–16 Evidence of nitrate attenuation in intertidal and subtidal groundwater in a subterranean estuary at a Cape Cod embayment, East Falmouth, Massachusetts, 2015–16
Nitrogen dynamics in intertidal and nearshore subtidal groundwater (subterranean estuary) adjacent to the Seacoast Shores peninsula, Falmouth, Massachusetts, were investigated during 2015–16 by the U.S. Geological Survey. The peninsula is a densely populated residential area with septic systems and cesspools that are substantial sources of nitrogen to groundwater. The study area is in...

Streamflow, water quality, and constituent loads and yields, Scituate Reservoir drainage area, Rhode Island, water year 2021 Streamflow, water quality, and constituent loads and yields, Scituate Reservoir drainage area, Rhode Island, water year 2021
As part of a long-term cooperative program to monitor water quality within the Scituate Reservoir drainage area, the U.S. Geological Survey in cooperation with Providence Water (formerly Providence Water Supply Board) collected streamflow and water-quality data in tributaries to the Scituate Reservoir, Rhode Island. Streamflow and concentrations of chloride and sodium estimated from...

Using the horizontal-to-vertical spectral ratio method to estimate thickness of the Barry Arm landslide, Prince William Sound, Alaska Using the horizontal-to-vertical spectral ratio method to estimate thickness of the Barry Arm landslide, Prince William Sound, Alaska
Conducting detailed investigations of large landslides is difficult, especially in the subsurface, largely due to environmental factors such as steep slopes, difficult access, and numerous objective hazards. These factors have made it challenging to accurately estimate the depth to the failure surface of the Barry Arm landslide, a large (roughly 108 cubic meters), deep-seated bedrock...

Predictions of groundwater PFAS occurrence at drinking water supply depths in the United States Predictions of groundwater PFAS occurrence at drinking water supply depths in the United States
Per- and polyfluoroalkyl substances (PFAS), known colloquially as “forever chemicals”, have been associated with adverse human health effects and have contaminated drinking water supplies across the United States owing to their long-term and widespread use. People in the United States may unknowingly be drinking water that contains PFAS because of a lack of systematic analysis...

Reducing wastewater nitrogen loading by >90% with carbon-amended septic systems: A field demonstration in Barnstable (Cape Cod), Massachusetts Reducing wastewater nitrogen loading by >90% with carbon-amended septic systems: A field demonstration in Barnstable (Cape Cod), Massachusetts
Onsite wastewater treatment systems (OWTS) are a major source of excess nutrients and co-pollutants in watersheds across the United States. In Barnstable County (Cape Cod), Massachusetts, effluent from septic systems and cesspools contributes approximately 80% of the controllable reactive nitrogen (N) load to numerous impaired estuaries and degrades water quality in the region's sole...

Vermont Flood Data Viewer Comparing 2023 and 2011 High-Water Marks Vermont Flood Data Viewer Comparing 2023 and 2011 High-Water Marks
Between 3 to 9 inches of rain fell within 48 hours across the state of Vermont over four days in July 2023 causing significant flooding and millions of dollars in damage. The high amount of rain caused several rivers to peak at record levels, in some cases exceeding records set during Tropical Storm Irene in 2011. This dashboard compares the high-water marks of the two storms.
