Initial input well data for logistic regression for a study of groundwater vulnerability to elevated nitrates in the Puget Sound Basin, Washington, 2000–19 This archive contains the well input data for the logistic regression model for the five-year categories 2000-2004, 2005-2009, 2010-2014, and 2015-2019. Data were collected either at the well location or computed within a buffer area of the well location, as specified in the parameter definition. Categories: Data; Tags: Groundwater, Wells, Drinking Water, Puget Sound, Washington, environment, health
Input data for logistic mapping at the conceptual well locations for a study of groundwater vulnerability to elevated nitrates in the Puget Sound Basin, Washington, 2000–19 This archive contains the input data for the conceptual well locations for the logistic mapping. Data were computed for either the well location or within a buffer area of the well location, as specified in the parameter definition.

Output vulnerability difference rasters from logistic mapping at the conceptual well locations for a study of groundwater vulnerability to elevated nitrates in the Puget Sound Basin, Washington, 2000–19 This archive contains the logistic mapping output vulnerability difference rasters at the conceptual well locations. Data are provided in rasters containing the differences between estimated probabilities of nitrate concentrations greater than 2 milligrams per liter at hypothetical 150 feet and 300 feet deep wells for sequential five-year categories when one or both of the predicted probabilities was equal to or greater than 50 percent.

Supporting GIS files in study to estimate groundwater vulnerability for elevated nitrates in the Puget Sound Basin, Washington, 2000-19 This archive contains shapefiles of the grid of conceptual well locations and study area. Categories: Data; Types: Downloadable, Map Service, OGC WFS Layer, OGC WMS Layer, Shapefile; Tags: Drinking Water, Groundwater, Puget Sound, Washington, Wells, All tags... environment, health, Fewer tags
Output vulnerability and vulnerability difference data from logistic mapping at the conceptual well locations for a study of groundwater vulnerability to elevated nitrates in the Puget Sound Basin, Washington, 2000–19 This archive contains the logistic mapping output data at the conceptual well locations. Data are provided in spreadsheets containing the estimated probabilities of nitrate concentrations greater than 2 milligrams per liter at hypothetical 150 feet and 300 feet deep wells for each of the five-year categories from 2000 to 2019 and vulnerability differences between five-year categories when one or both of the predicted probabilities was equal to or greater than 50 percent.

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
