Attribute: ANCACODE

code		description
D		Derived anion-cation ratio value is based on the full set of anions and cations
D*		Derived value - mathematically determined from other analytical measurements, one or more of which were below the detection limit
DE		Derived value - mathematically determined from other analytical measurements, one or more of which were estimated values
DQ		Derived value - mathematically determined from other analytical measurements, one or more of which were questionable values
N		No anion-cation ratio calculation determined due to missing analytical components
