From the Executive Summary:
Clean water is essential to our health, our communities, and our lives. Yet our water infrastructure (drinking water, wastewater, and stormwater systems, dams, and levees) is seriously outdated. In addition, we have degraded much of our essential natural infrastructure (forests, streams, wetlands, and floodplains). Climate change will worsen the situation, as rising temperatures, increased water demands, extended droughts, and intense storms strain our water supplies, flood our communities, and pollute our waterways.
