Cross-sectional associations between drinking water arsenic and urinary inorganic arsenic in the US: NHANES 2003-2014

Background: Inorganic arsenic is a potent carcinogen and toxicant associated with numerous adverse health outcomes. The contribution of drinking water from private wells and regulated community water systems (CWSs) to total inorganic arsenic exposure is not clear. Objectives: To determine the association between drinking water arsenic estimates and urinary arsenic concentrations in the 2003-2014

Preliminary machine learning models of manganese and 1,4-dioxane in groundwater on Long Island, New York

Manganese and 1,4-dioxane in groundwater underlying Long Island, New York, were modeled with machine learning methods to demonstrate the use of these methods for mapping contaminants in groundwater in the Long Island aquifer system. XGBoost, a gradient boosted, ensemble tree method, was applied to data from 910 wells for manganese and 553 wells for 1,4-dioxane. Explanatory variables included soil

2022 drought in New England

Introduction During April through September 2022, much of New England experienced a short but extreme hydrologic drought that was similar to the drought of 2020. By August 2022, Providence, Rhode Island, was declared a Federal disaster area, and New London and Windham counties in Connecticut were declared natural disaster areas. Mandatory water use restrictions were put in place in communities in

Long Island Sound Spatially Referenced Regressions on Watershed Attributes (SPARROW) Models

The U.S. Geological Survey, New England Water Science Center, in collaboration with the U.S. Environmental Protection Agency (EPA), is modeling seasonal nutrient loads to Long Island Sound (LIS). Nutrients that originate from within the 41,867-square-mile section of the LIS watershed that is north of the Sound include both point (specific) and nonpoint (widespread) sources. Dynamic modeling of the...

Stream Flood Vulnerability Assessment at Acadia National Park

The U.S. Geological Survey (USGS) New England Water Science Center, in cooperation with Acadia National Park, is assessing the vulnerability of the park’s streams, culverts, and bridges to flood damage and erosion using design flows for selected high streamflow recurrence intervals to inform management decisions on infrastructure upgrades.
