Purpose

These shapefiles were created to define the grid and study area for this study titled "Index of Vulnerability for Elevated Nitrates in Groundwater in the Puget Sound, Washington." Logistic regression models were used to estimate groundwater vulnerability to elevated nitrate concentrations in the Puget Sound Basin, Washington, at five-year intervals during 2000–19.
