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.
