On This Day: April 20
Today is Monday, April 20, 2015. This is the 110th day of the year, with 255 days remaining in 2015.
Fact of the Day: aquifers
Aquifers are groundwater systems. They serve the diverse agricultural, industrial, recreational, and domestic needs of millions of users. In some places it is the only source of water. In the coming decades, demand for water may increase beyond the aquifers' capacity to provide, and there are increasing concerns about the welfare of endangered species that depend on aquifer water. Overdrafts on an aquifer would imply that too much water is being drawn from an aquifer.
