Prioritising water conservation, infrastructure improvements, and sustainable policies will help secure a healthier future for all.
[351] Climate Change Impacts on Freshwater Resources | US EPA — Water utilities spend more than $109 billion each year to provide safe drinking water and wastewater services in the communities they serve.17 Nonetheless, more than 7 million people get sick from diseases spread through water each year.18 These illnesses cost the U.S. health care system more than $3 billion annually, and climate impacts are expected to increase risk of exposure to water-borne pathogens and water-treatment expenses.19, 20, 21 Certain groups of people in the United States, including Indigenous communities, low-income communities, communities on the U.S.–Mexico border, migrant farm workers, and others lack access to clean water and sanitation services.22 Climate impacts will compound this situation. We can reduce climate change’s impact on water resources in many ways, including the following:
[352] Water and Climate Change — Water and Climate Change | UN-Water About UN-Water Water and Climate Change Water and Climate Change Climate change is primarily a water crisis. However, water can fight climate change. Water and climate change are inextricably linked. Sustainable water management helps society adapt to climate change by building resilience, protecting health and saving lives. It also mitigates climate change itself by protecting ecosystems and reducing carbon emissions from water and sanitation transportation and treatment. United Nations (UN): UN World Water Development Report 2020: Water and Climate Change UN-Water: UN-Water Policy Brief on Climate Change and Water 2019 UN-Water: World Water Day 2020 campaign: Water and Climate Change Only 0.5% of water on Earth is useable and available freshwater – and climate change is dangerously affecting that supply.

[354] Urbanization - Water and Sediment Quality | US EPA — Example Water (Malibu Creek, Etowah River) and Sediment (Charles River and Stillwater River) Quality Differences Between Urban and Non-Urban Stream Sites One common water quality change associated with urban development is an increase in nutrient concentrations, especially nitrogen (Figure 24, Table 6). Although nitrogen loading to and export from urban streams typically are elevated, many studies also have found relatively high nitrogen retention [Groffman et al. PAH concentrations in stream sediments were 3.9 to 32 mg kg-1 higher downstream of coal-tar seal-coated parking lots versus upstream reference sites (Scoggins et al. Increases in pool habitat PAH sediment toxicity units between sites upstream and downstream of seal-coated parking lots explained decreases in macroinvertebrate richness and density (Figure 25).
