Soil Concentration File (.SCF)
There are currently four qualified types of the SCF, those qualifiers are: "Soil", "Soil-Dissolved" "Sediment", "Sediment-Dissolved". When the qualifiers "Soil" or "Sediment" are used, "-Total" is implied. The constituent concentrations are a spatial average throughout the volume of the soil/sediment zone. The concentrations units in the zone depend on whether the constituent is a radionuclide or chemical and which qualifiers is used and constituent phase measured. These concentration values are the instantaneous values at that specified time, not an average. Every data set denotes another location, in most cases a downstream icon, but not always so. There are NO limits on number of data sets, constituents, progeny, and time/concentration pairs.
The following outline is a description of the basic information provided in an SCF. This file may be modified through an API. See the Software Development Kit (SDK) for more information. An example SCF is included after the outline. Comparing the line-by-line description in the outline to the example should clarify and help locate data contained in the SCF. Lines beginning with ';' are descriptive comments only and will not appear in the actual SCF.

For each 'Data Set'
A line with:
Data Set name - [STRING]
;This is the location name or ID.
;If the set is intended for a particular consumming module's use then

;File qualifier determines concentration units and aids in connection scheme:
;Soil - "pCi/kg" / "mg/kg" - Total constituent mass per dry weight of soil
;Soil-Dissolved - "pCi/L" / "mg/L" - Dissolved constituent mass per volume of soil water
;Sediment - "pCi/kg" / "mg/kg" - Total constituent mass per dry weight of sediment
;Sediment-Dissolved - "pCi/L" / mg/L - Dissolved mass in water per volume of water
Number of Time Concentration Pairs - [INTEGER]
Number of progeny - [const INTEGER] - 0
; must be set to zero for 1.6+ specifications
