#
#	Summary of data archived from report 
#	"Estimates of tracer-based piston-flow ages of groundwater from selected sites: 
#	National Water-Quality Assessment Program, 1992–2005", 
#	U.S. Geological Survey Scientific Investigations Report 2010-5229, 
#	URL: http://pubs.usgs.gov/sir/2010/5229/
#   
#	SIR 2010-5229 documents age-dating data from selected sites 
#	sampled between 1992 and 2005 as part of the 
#	USGS NAWQA Program.  
#	This report was itself an archive of age-dating data, 
#	and the extensive appendices (115 different tables) 
#	serve as an archive of age-dating data and of 
#	parameter values (e.g. recharge temperature, recharge elevation, 
#	excess air) used to interpret the age-dating data.  
#	The appendices also provide discussion of the age-dating process 
#	on a network-by-network basis.  
#	Absent from SIR 2010-5229 are notes specifically noting the 
#	process used to select the most appropriate of the various CFCs 
#	for each site that was dated with CFCs.  
#	Those notes are archived in a dataset labeled, 
#	"ARCHIVE_AGE_DATING_DATA_SIR_2010_5229.txt".
#	This (one) file consists of notes recording this process.

#
#   This data set contains notes that 
#	provide additional documentation regarding the interpretation of 
#	CFC concentrations. The general process was described in the body of a report  
#	(SIR 2010-5229), and greater detail was provided in the appendix of that report 
#	(in 115 tables). The notes provided in this dataset represent additional detail 
#	regarding the interpretation of the CFC data (detail too fine for inclusion 
#	in the report, but possibly valuable for future investigators).
