Infectious Disease and Water Quality
Throughout the world increased climatic variability has exacerbated floods and droughts. All regions of the world show an overall net negative impact of climate change on water resources and freshwater ecosystems. Areas in which runoff is projected to decline are likely to face a reduction in the value of the services provided by water resources. The beneficial impacts of increased annual runoff in other areas are likely to be tempered in some areas by negative effects of increased precipitation variability and seasonal runoff shifts on water supply, water quality and flood risks (IPCC, 2007). The years 2004 and 2007 marked two of the earliest spring melts on record in the western US, and 2007 was one of the driest years on record in California. Glaciers are disappearing across the West, and Glacier National Park in Montana may have no glaciers by 2030. Warming temperatures and corresponding shifts from solid to liquid precipitation have profound implications for water supplies and management (Lundquist and Roche, 2011).
