In 1991, the U.S. Geological Survey (USGS) began a study of more than 50 major river basins across the Nation as part of the National Water-Quality Assessment (NAWQA) project of the National Water-Quality Program. One of the major goals of the NAWQA project is to determine how water-quality conditions change over time. To support that goal, long-term consistent and comparable monitoring has been conducted on streams and rivers throughout the Nation. Outside of the NAWQA project, the USGS also has collected long-term water-quality data to support additional assessments of changing water-quality conditions. These data have been combined to provide insight into how natural features and human activities have contributed...

This data release contains GIS layers and associated metadata in support of a hydrologic assessment of the Edwin B. Forsythe National Wildlife Refuge, New Jersey. Water-table elevation contours and a depth-to-water grid are included. Water levels measured at groundwater and surface-water sites located in and near the refuge as part of a water-level synoptic study conducted primarily during May 2015 were used in the development of both layers, along with other spatial data. Included is one shapefile with associated metadata: ebf_wtelev_spring2015: continuous water-table elevation contours. Also included is one grid file with associated metadata: ebf_dtw_spring2015: depth-to-water grid. This data release supports...

This data release provides estimates of annual agricultural use of pesticide compounds in counties of the conterminous United States, for years 2013-17, compiled by means of methods described in Thelin and Stone (2013) and Baker and Stone (2015). For all States except California, U.S. Department of Agriculture county-level data for harvested-crop acreage were used in conjunction with proprietary Crop Reporting District-level pesticide-use data to estimate county-level pesticide use. Where Crop Reporting District data were not available or were incomplete, estimated pesticide-use values were calculated with two different methods, resulting in a low and a high estimate based on different assumptions about missing...
Note: Revisions to the dataset were necessary because the original dataset was incomplete. Data for select compounds were missing from the original (version 1) pesticide use estimates. This data release has been superseded by version 2.0, available here: https://doi.org/10.5066/P9F2SRYH.
