Abstract
Analysis of climate change impacts upon water resources has focused prim arily on water quantity issues. The impacts upon water qu ality and water quality management have had little attention. This paper presents a framework for assessing climate change impacts upon stream water quality and the management costs associated with adaptation to the new hydroclim atic conditions resulting in changes in streamflow and stream temperature. W ater quality indicators as well as chemical and biological processes important to water quality are a fu nction of stream temperature. This paper reports not on ly on how water quality indices will be im pacted by alternative climate change scenarios, but on the econom ic cost of maintaining water quality stan dards. The costs of maintaining water quality standards result from increased treatm ent of waste loads due to decreased waste assimilation capacity of warmer streams. A case study based on regionally developed climate change scenarios shows that water quality levels ar...
