Ground Water (Other) Data Dictionary Column Name Description Datatype ... Base Lower elevation of the specified aquifer (feet above sea level) Integer ... Sand Thickness of the sand (feet) for the specified aquifer Integer ... Top Upper elevation of the specified aquifer (feet above sea level) Integer Aquifer 1 Aquifer in which well is located (as determined by the data source) Character Aquifer 2 If well is located in two aquifers, name of second aquifer (as determined by Character the data source) Average Flw ~9Pm) Average testing discharge rate measured in gallons per minute Numeric Base Interval (ft) Base of tested interval in feet Integer D1000 =1000; lower reference point for interval from 500-1000 feet Integer D1000 1500k Net saturated thickness in feet from 1000 feet to total depth (if < 1500) or Integer _ 1500 feet (if total depth > 1500) D1500 2000k Net saturated thickness in feet from 1500 feet to total depth (if <2000) or Integer _ 2000 feet (if total depth >2000) D2000 =2000; lower reference point for interval from 1500-2000 feet Integer D2000 2500 Net saturated thickness is feet from 2000 feet to total depth (if <2500) or Integer _ 2500 feet (if total depth >2500) D2500 =2500; lower reference point for interval from 2000-2500 feet Integer D2500 3000 Net saturated thickness in feet from 2500 feet to total depth (if <3000) or Integer _ 3000 feet (if total depth >3000) D3000 =3000; lower reference point for interval from 2500-3000 feet Integer D3000 3500k Net saturated thickness in feet from 3000 feet to total depth (if <3500) or Integer _ 3500 feet (if total depth >3500) D3500 =3500; lower reference point for interval from 3000-3500 feet Integer D3500 4000k Net saturated thickness in feet from 3500 feet to total depth (if <4000) or Integer _ 4000 feet (if total depth >4000) D4000 =4000; lower reference point for interval from 3500-4000 feet Integer = 500; Lower reference point for interval from the top of the confined D500 aquifer to 500 feet. Equal to well total depth if the well penetrates a Integer confining layer and well total depth <500 D500to1000k Net saturated thickness in feet from 500 feet to total depth (if < 1000 feet) Integer or 1000 feet (if total depth > 1000) Data Source Source (provider) of the data (O&G, DWR, USGS, etc.) Character Dcon500k Net saturated thickness in feet from the top of the confined aquifer to total Integer depth (if <500 feet) or 500 feet (if total depth >500 feet) Depth in feet to the first impermeable geologic unit of 10 feet or greater. Dcontop Only filled in for wells which penetrate a confining layer. Will be equal to Integer DUNCBASE if well penetrates a confining layer DSS Aquifer 1 Aquifer in which well is located (as determined by the DSS program) Character DSS Aquifer 2 If well is located in two aquifers, name of second aquifer (as determined by Character the DSS program) Depth in feet to first impermeable geologic unit of 10 feet or greater; In Duncbase wells which do not penetrate such a unit, this value equals the total depth Integer of the well
