Flood of July 2023 in Vermont
A major storm caused catastrophic flooding in many parts of Vermont on July 9–12, 2023, resulting in millions of dollars in damages. The high amount of rainfall caused several rivers to peak at record levels, in some cases exceeding records set during Tropical Storm Irene in 2011. The U.S. Geological Survey, in cooperation with the Federal Emergency Management Agency, collected and...
Nitrate loads and concentrations from forested watersheds and implications for Long Island Sound
Reduction in point sources of nitrogen has led to improvement in water quality of the Long Island Sound (LIS) since 2000, but changes in nonpoint sources are less clear. A significant yet poorly quantified nonpoint nitrogen source is the forested landscape. Because a large proportion of the LIS basin is forested, even small areal inputs from the forested landscape have a large cumulative...
Base-flow sampling to enhance understanding of the groundwater flow component of nitrogen loading in small watersheds draining into Long Island Sound
Excessive nitrogen discharge is a major concern for the Long Island Sound. Programs have been implemented to reduce point sources of nitrogen to the sound, but little is known about the nonpoint sources. This study aims to better understand the current groundwater contributions of nitrogen from nonpoint sources in the Long Island Sound watershed.During the spring and summer of 2022, the...

Susceptibility of Water Resources to Water-Quality Impairment from Onsite Wastewater Disposal in Rhode Island
The U.S. Geological Survey (USGS), in cooperation with the Southeast New England Program (SNEP) of the U.S. Environmental Protection Agency and the Rhode Island Department of Environmental Management, is investigating the relationship between onsite wastewater treatment systems and nitrogen loads in water bodies in the Narragansett Bay watershed in Rhode Island.
Estimating Nitrogen Loading from Groundwater and Potential Effects of Sea-Level Rise in Rhode Island's Salt Ponds Region
The U.S. Geological Survey (USGS), in cooperation with the Southeast New England Program of the U.S. Environmental Protection Agency, is estimating the magnitude, spatial distribution, and travel times of nitrogen-loading to ponds and streams in the Salt Ponds region of southern Rhode Island. This information can be used to guide conservation-management efforts aimed at reducing nitrogen inputs to...
