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 that was densely populated with residences having septic systems and legacy cesspool inputs of inorganic nitrogen. This estuary is one of many small embayments on Cape Cod where nutrient enrichment can lead to eutrophication and is a major concern for water-quality impairment. Groundwater water-quality data were collected from 3 transects from a total of 27 locations that were sampled between November 2015 and October 2016. Samples were...

Water-quality samples were collected in 2003, 2005, and 2012 through 2018 in and near seven kettle lakes located on western Cape Cod, with most of the data collected in 2015-2017 from Ashumet Pond, which is located in the towns of Falmouth and Mashpee. Data were also collected at other lakes to compare the lake-specific influences of geochemistry and hydrology on the downgradient groundwater...

The sampled ponds included Ashumet, Santuit, Snake, Shubael, and Longs. Pore water was collected between 15 to 100 cm below the pond bottoms on the upgradient and downgradient sides of the ponds. Groundwater was collected on the downgradient side where the pond water recharges the groundwater resulting in a “pond shadow”. Within the pond shadow, groundwater is under the direct influence of surface water. The pond shadows were sampled vertically and at various...

Samples (total = 445) include river water from the Upper Illinois River and its major tributaries plus urban wastewater and agricultural groundwater. Data include concentrations of nitrate, chloride, and sulfate; isotope ratios of N and O in nitrate; and isotope ratios of H and O in water.

The analysis is described in U.S. Geological Survey Scientific Investigations Report 2018-5095 by Colman and others (2018). This data release is structured as a set of comma-separated values (CSV) files, each of which contains data columns for laboratory (if applicable), USGS Site Name, date sampled, time sampled, and columns of specific analytical and(or) other data. The .csv data files have the same number of rows and each row in each .csv file corresponds...

The Iroquois River and Sugar Creek, located in northwestern Indiana and northeastern Illinois have been heavily impacted by agricultural land use and contain relatively high concentrations of inorganic nitrogen, primarily as nitrate. As part of that study, samples were collected and analyzed for dissolved methane and nitrous oxide concentrations to determine greenhouse gas (GHG) concentrations in the streams and the relation of GHG concentrations to concentrations of other inorganic nitrogen species in the water. These data are the results of that study. The data include GHG and nutrient samples collected...

A portion of the contaminated groundwater discharges into Ashumet Pond, a kettle hole, freshwater lake. A study was conducted from June 2013 to June 2015 to document transport, transformation, and discharge of dissolved inorganic nitrogen species (DIN; nitrate, nitrite, and nitrous oxide) from the contaminant plume to the lake, across the groundwater-surface water interface. Groundwater, lakewater, lake sediment porewater, and sediment cores were collected and analyzed for DIN constituents as well as functional gene abundance for key N-cycle...
