The presentation reviews several approaches for determining dissolved inorganic carbon (DIC) in drinking water. Experimental studies compared the accuracy and precision of DIC determination obtained by either direct analysis using a coulometric titration technique, or by comutation from a complete water analysis using the WATEQX equilibrium chemical speciation model. The two methods gave equivalent DIC values at the 95% confidence level. However, pH and total alkalinity accuracy and precision must be optimized to achieve equivalence, or else direct analysis is better. Factors that can be controlled, and analytical method adjustments are discussed, to enable better DIC determination for laboratories.
