Available QW covers for Cambrio-Ordovician
			
		
		The cover names generally describe the contents with a couple of 
exceptions. The cover surf_buried refers to a two-polygon cover showing 
where the Cambrian/Ordovician is either at the bedrock surface or is 
buried beneath other bedrock deposits, like Silurian. The cover maj_nut 
includes major inorganics and nutrients. Data from the old RASA study are 
included in that cover along with the newer NAWQA data. The pesticide data 
is spread out over five different covers which are named by the sample 
schedule used for analysis. Combining all pesticide parameters into one 
cover would have made a cover with way too many items to practically look 
at. Besides, Excel, which was used in the processing, wouldn't have 
handled so many items in one worksheet. Item names are the names of the 
constituents themselves, unless the name becomes more than 16 characters 
long. In that case, the item name becomes the parameter code. Parameters 
with the potential for remarks will have a item for the associated remark. 
So, the item called benzine will have another item called benzine.rmk. 
When data are plotted to the screen by my program site_analysis, the 
program will check if a remark field is associated with the constituent 
and plot the remark value. That's all I can think of now, but call if you 
have questions.
