“The Freshwater Connection”

How do we use freshwater in US?
In addition to home use, fresh water is used for transportation, agriculture, heating and cooling, industry, livestock, and many other purposes. That one percent of water is primarily used in eight different ways, or categories:
• Domestic. Residential home indoor and outdoor use, such as drinking, cleaning, and watering lawns
• Public supply. Public and commercial buildings, such as schools and restaurants
• Irrigation. Watering systems for farms that grow food
![Page 11: Water availability and conservation](https://reader034.vdocuments.us/reader034/viewer/2022042716/55a8c0101a28abe1318b4711/html5/thumbnails/11.jpg)
Freshwater Usage
• Livestock. Watering systems for animals on ranches and farms
• Aquaculture- Watering systems for fish farms and hatcheries
• Industrial -Water used for manufacturing products, including food, paper, and petroleum products
• Mining- Water used for extracting natural resources such as metals, minerals, natural gas, and oil
• Thermoelectric- Water used for generating electricity using steam-driven generators

Keeping track of freshwater
• Rain gauges- not evenly distributed, none over oceans, measures at local level which varies widely
• Weather radar- ground-based, not evenly distributed, not over oceans, measures at local level
• Satellites: operational and research, global level
NOAA, NWS- operational: predicting, forecasting
NASA- research:
Impact of climate change on freshwater availability
Impact of global rainfall on natural disasters: drought, tropical cyclones, landslides, etc…
World health concerns: water-borne disease, water availability, etc…
