Mercury Concentrations in Wild Rice, Bad River Watershed, Wisconsin, 2006

Seven wild rice samples were collected in 2006 in or near to Bad River tribal lands and analyzed for methyl Hg. Neither the collection of wild rice samples nor the Hg analyses were performed by the U.S. Geological Survey, New York Water Science Center.

Mercury Concentrations in Surface Waters, Bad River Watershed, Wisconsin, 2006-2016

These data represent mercury (Hg), filtered total Hg (FTHg), filtered methylmercury (FMHg), particulate total Hg (PTHg), particulate methylmercury (PMHg), total mercury (THg), dissolved organic carbon (DOC) and total organic carbon (TOC) concentrations in surface water samples collected on Bad River Tribal lands. Several samples were collected at multip

Mercury Concentrations in Bed Sediment, Bad River Watershed, Wisconsin, 2006-2015

These data represent total mercury (Hg) concentrations and percent organic carbon in bed sediment from 51 samples collected at 44 location in streams and rivers during 2006 to 2015 within or near to Bad River Tribal lands. Reach lengths are provided when they were available, and the data set includes sieved, unsieved, and samples where sieving status was not indicated. Samples were coll

Mercury Concentrations in Bald Eagle Feathers, Bad River Watershed, Wisconsin, 2014-2016

The breast feathers of 13 bald eagles were collected at 11 locations during 2014 to 2016 along rivers and sloughs on or near to Bad River tribal lands and analyzed for total mercury (Hg) concentrations. An age (7 - 9 weeks) was indicated for only two of the eagle feather samples. The eagle feathers sampled were likely all from nestlings, but this could be confirmed for only two of the e

Mercury Data from the Bad River Watershed, Wisconsin, 2004-2018

This release includes eight data files that provide concentrations of mercury (Hg) chemical species and ancillary chemical and physical data that quantify and document aspects of the Hg cycle in stream and rivers located on tribal lands of the Bad River Band of Lake Superior Chippewa. These files were transferred to the U.S. Geological Survey by Lacey Hill Kastern, Natural Resources Departm...

Mercury Concentrations in Fish Tissue, Bad River Watershed, Wisconsin, 2004-2013

These data represent Hg concentrations in tissue from 104 analyses of fish samples collected at 7 sites in streams/rivers and lakes during 2004 to 2013 within or near to Bad River Tribal lands. Nine fish species are represented in this dataset. Most fish specimens were collected by the Bad River Tribe, but collection agency was not always indicated in source files.

Mercury Concentrations in Litterfall, Bad River Watershed, Wisconsin, 2012-2018

Annual litterfall samples were collected and analyzed for THg (total mercury) and MHg (methyl mercury) at a site (WI95) on Bad River tribal lands during 2012 to 2018. Litterfall was collected at a second site, WI01, during 2012 only. Litterfall was sampled in eight collectors, from which annual mass was determined. Total mercury analyses were performed on only four samples from

Pesticides, nutrients, and inorganics in shallow groundwater, Long Island, NY, 2016-2018

Groundwater samples collected between 2016 and 2018 from 56 shallow (<40 m depth) monitoring wells in Long Island, N.Y., were collected in support of the Long Island Pesticide Pollution Prevention Strategy. Each well was sampled at least once and analyzed for over 200 pesticides and pesticide degradates as part of this study. Results presented here also include field and inorganic analy

Methylmercury and associated data in macroinvertebrates from tributaries of Honnedaga Lake and from the Middle Branch Black River in New York.

Macroinvertebrate samples were collected from streams tributary to Honnedaga Lake and from the Middle Branch of the Black River during 2012-2016 and analyzed for methylmercury concentrations and for stable isotope ratios of nitrogen and carbon. Macroinvertebrates were identified in the field, and the level of taxonomic resolution varied from order to species; most taxa were identified to the...

Data for statewide assessment of New York's karst aquifers with an inventory of closed-depression and focused-recharge features

The New York State Departments of Environmental Conservation and Health are concerned about groundwater contamination in the carbonate-bedrock aquifers with the potential to host karst features throughout New York State, especially relating to the unintended introduction of chemical or agricultural contamination into these aquifers. USGS Scientific Investigations Report, SIR 2020-5030 (Kap...

Fish mercury concentration data and ancillary data for streams and rivers across New York State (United States), 1969-2016, including environmental characteristics of selected locations sampled during 2007-16

Fish mercury (Hg) data were compiled for 392 unique locations on freshwater streams and rivers in New York State for the period 1969-2016. A total of 7620 records were compiled from state, federal, and non-governmental organization databases. The compiled data were for samples of 65 non-anadromous species or species groups in which Hg was analyzed in whole fish or edible flesh, and for
