Select Groundwater-Quality and Quality-Control Data from the National Water-Quality Assessment Project 2019 to Present (ver. 4.0, April 2025) Select Groundwater-Quality and Quality-Control Data from the National Water-Quality Assessment Project 2019 to Present (ver. 4.0, April 2025)
Groundwater samples were collected and analyzed from 1,015 wells as part of the National Water-Quality Assessment Project of the U.S. Geological Survey National Water-Quality Program and the water-quality data and quality-control data are included in this data release. The samples were collected from three types of well networks: principal aquifer study networks, which are used to assess...
Bias-corrected daily precipitation at 1-kilometer resolution for Puerto Rico from Weather Research and Forecasting (WRF) dynamical downscaled historical (1985-2005) and projected (2040-60) climate Bias-corrected daily precipitation at 1-kilometer resolution for Puerto Rico from Weather Research and Forecasting (WRF) dynamical downscaled historical (1985-2005) and projected (2040-60) climate
This data release consists of four network Common Data Form (netCDF) files of bias-corrected daily precipitation at 1-kilometer (km) scale for historical and projected climate of Puerto Rico. The Weather Research and Forecasting (WRF) model was used by Bowden and others (2018) to downscale two general circulation models (GCMs) from the Coupled Model Intercomparison Project phase 5 (CMIP5...

Data Collected to Assess the Occurrence and Distribution of Per- and Polyfluoroalkyl Substances in West Virginia Public Source-Water Supplies, 2019 - 2021 Data Collected to Assess the Occurrence and Distribution of Per- and Polyfluoroalkyl Substances in West Virginia Public Source-Water Supplies, 2019 - 2021
Source water for West Virginia’s public water systems is pumped from groundwater aquifers or withdrawn from the state’s rivers and lakes. These systems provide drinking water to a majority of the state’s population and require constant monitoring for known and emerging contaminants. Groundwater contamination from Per- and Polyfluoroalkyl Substances (PFAS) has occurred in West Virginia...
Histopathology of little brown bats (Myotis lucifugus) collected from a maternity roost in Leelanau County, Michigan, USA, in June 2014 Histopathology of little brown bats (Myotis lucifugus) collected from a maternity roost in Leelanau County, Michigan, USA, in June 2014
This work is part of a study investigating the movement of microcystin from aquatic to terrestrial ecosystems via trophic transfer. Little brown bats (Myotis lucifugus), feeding opportunistically on aquatic insects including Hexagenia mayflies, were collected from a maternity roost near Little Traverse Lake (Leelanau County, Michigan, USA). Bats and fecal samples were collected for...
Data set on reticuloendotheliosis in Hawaiian birds Data set on reticuloendotheliosis in Hawaiian birds
Only one virus, Avipox, has been documented in wild birds in Hawaii. Here, using immunohistochemistry and PCR, we found that two native threatened Hawaiian geese, one with multicentric histiocytoma and another with toxoplasmosis and one Laysan albatross with avian pox were infected with reticuloendotheliosis virus (REV). The virus was isolated from one of the geese by cell culture. PCR...
