Dr. Parkhurst,
Two questions involving parameter/data entry into
Preeqc Interactive 2.7.
1. Does the program know what
oxidation state to designate to metals such as Iron, Manganese and Arsenic given
specified parameters such as pe, pH, and Temperature? Or should I assume
that in a reductive environment to use the reduced forms and vice versa for
oxidated environment? I am sampling using EPA low flow methods.
2. If I have both Alkalinity and
Dissolved Inorganic/Organic Carbon values, is there a way I can enter the DOC or
DIC?
Any advice you could give concerning these issues
would be greatly appreciated.
Thank you very much
-Matt
