Water Quality and Climate

Climate change can have a variety of impacts on surface water, drinking water, and ground water quality. Higher water temperatures and changes in the timing, intensity, and duration of precipitation can affect water quality. Higher air temperatures (particularly in the summer), earlier snowmelt, and potential decreases in summer precipitation could increase the risk of drought. The frequency and intensity of floods could also increase.  In addition, sea level rise may affect freshwater quality by increasing the salinity of coastal rivers and bays and causing saltwater intrusion—the movement of saline water into fresh ground water resources in coastal regions.
