The future of water conservation, created for the National Science Foundation's Engineering directorate
A look at the small percentage of Earth's water that is 'freshwater' (97.5% salt, 2.5% fresh). Of the 2.5% that is freshwater, 69% is frozen in glaciers and ice caps, 30% is groundwater, and only 1% is accessible in surface water like lakes and rivers. It's essential that we smartly capitalize on our groundwater sources while maximizing reservoir replenishing; especially in places prone to drought.
For Sustainable Conservation
Only 1% of Earth's freshwater is accessible from surface sources, such as lakes and rivers. 69% of the Earth's freshwater is locked in ice, and the remaining 30% of freshwater is groundwater providing critical "savings account" for dry years. During droughts, people turn to this source for water, with some residents relying solely on groundwater for drinking, cooking, and bathing. However, these reserves are shrinking, and it's essential to develop strategies to smartly use and replenish groundwater sources. Dashed cloud outlines show predicted precipitation changes as the Earth's climate warms.
California Ground Water Map: California has an extensive groundwater network, shown in this map. During droughts, these underground reservoirs are of particular importance. However, these reserves are shrinking, and it's essential to develop strategies to smartly use and replenish groundwater sources. Data from the State of California Department of Water Resources.
