Each GWSI site has a unique Site ID and Local ID. The Site ID is a 15-digit ID number initially derived from the latitude and logitude of the site. The Site ID number is a unique identifier and not a locator. The Local ID is a 20+ character long site location based on the US Bureau of Land Management’s system of land subdivision for Arizona. For more detailed descriptions of these site identifiers, see the GWSI Handbook. Some sites have a State Well Registration (55) number. The Registration Number is matched with a GWSI well only when a field investigator is absolutely positive that the wells are the same. Note: Approximately 50% of GWSI wells have a 55 well registration number.
