Project SWIFT (Shale-Water Interaction Forensic Tools) Water Chemistry Database

The data set includes the following types of information for domestic wells sampled in southern New York State: geographic location (latitude and longitude), year of sample collection, concentrations of a variety of analytes, distances to various features (e.g. faults, gas wells, flow lines), topographic position, water type, well depth and type, and completion geology. Definitions of fields are provided in a worksheet within the Excel data file. When no data are available for a given field, the value is given as -9999. When concentrations are below a given detection limit, the value is given as -5555. The detection limits for chemical data in each year are given within a worksheet within the Excel data file.
