The fields lised below are included in the downloadable report data. Descriptions of the fields and any associated codes are as follows:

SITE_ID: ADWR's unique 15-digit identification number for the well in the GroundWater Site Inventory database

LOCAL_ID: Site's local ID or cadastral. Typically assigned based on the Bureau of Land Management's system, but may differ depending on the land net used in the area. 

REG_ID: Site's registration or 55 number, if known

WELL_ALT: Altitude of land surface at the site given in feet above mean sea level, based on NGVD29

LAT_NAD83: Latitude of the site's location measured using NAD83 and given in degree-minute-second notation

LONG_NAD83: Longitude of the site's location measured using NAD83 and given in degree-minute-second notation

SITE_AMA_CODE_ENTRY: Primary ADWR groundwater basin or Active Management Area code. 
CCK = Cienega Creek; SCA = Santa Cruz Actice Management Area; SRF = San Rafael; TUC = Tucson Active Management Area. 

SITE_ADWBAS_CODE_ENTRY: ADWR groundwater sub-basin that the site is located within. 
AVR = Avra Valley; CCK = Cienega Creek; SCA = Santa Cruz Active Management Area; SRF = San Rafael; USC = Upper Santa Cruz.
