Evaluating drinking water

Organic carbon in natural waters is a mixture of dissolved molecules, particles and colloids. The U. S. Environmental Protection Agency recently began to require water utilities to measure and report the concentrations of total organic carbon in their source waters. We have received a grant to evaluate the accuracy of the measurements required to ensure clean drinking water. As part of this study, we are seeking to develop relevant and generally applicable standards of measurement, which will enable the utilities to evaluate their own analytical capabilities.
