The Need…and Why Now?Nothing is more fundamental to life than water. Not only is water a basic need, but adequate safe water underpins the nation’s health, economy, security, and ecology.
NRC (2004) Confronting the nation’s water problems: the role of research.
● Water use globally will triple in the next two decades, leading to increases in erosion, pollution, dewatering, and salinization.
● Major U.S. aquifers (e.g., the Ogallala) are being mined and the resource consumed.
● Only ~55% of the nation’s river and stream miles and acres of lakes and estuaries fully meet their intended uses; ~45% are polluted, mostly from diffuse-source runoff.
● From 1990 through 1997, floods caused more than $34 billion in damages in the U.S.
● Of 45,000 U.S. wells tested for pesticides, 5,500 had harmful levels of at least one.
● Fish consumption advisories are common in more than 30 states because of elevated mercury levels (source: mostly fossil fuel combustion; mercury is a neurotoxin).

WATERS Network Grand Challenge from the November Joint CUAHSI/CLEANER Workshop
How are water quantity, quality, and related earth system processes affected by natural and human-induced changes to the environment?
• How do we detect and predict the effects of natural phenomena and human activities on the quantity, distribution, and quality of water across a range of scales?
• How do we manage, engineer, and adapt to aspects of the urban water cycle to achieve sustainable water use and availability for humans and ecosystems?
• How do hydrologic, biologic, geomorphic and chemical transformations in the atmosphere, surface and subsurface affect water quality over multiple space and time scales?
