ABSTRACT

A blending evaluation is a planning tool that can be particularly helpful when considering introducing new or additional source waters to a water system. A blending evaluation is a systematic approach to addressing the likely water quality impacts of changing source waters and if necessary, potential mitigation approaches. This paper discusses two North American case studies and a blending methodology that could be applied by any water system to plan for and mitigate a wide range of potential water quality issues.
