Estimate the CO₂ concentration in mg/L as CO₂ and in mg/L as CaCO₃ for the water analysis presented in Problem 4-8. Assume the water temperature was 6^oC.

Problem 4-8

The following mineral analysis was reported for a water sample taken from Well No. 1 at Magnolia, Illinois (Woller and Sanderson, 1976b). Determine the total, carbonate and noncarbonate hardness in mg/L as CaCO₃ and in meq/L using the predominant polyvalent cation definition of hardness.
