Water: Composition and Properties

What is the term for the reduction in the pressure head surrounding a pumped well?

What is the term for the significant drop in the regional water table due to the long-term pumping of water from a large number of wells?

What is the term for collecting the run-off from a structure or impervious surface to store it for later use?

What is the term for using less water and using it more efficiently?

What is the term for the measurement of the direct and indirect water use by a person, community, business, or country?

What are the chemical elements that compose water?

How many atoms make up a water molecule?

What is the term used to describe a situation where people lack access to sufficient water, clean water, or both?

When does water stress occur?

In which areas is water stress greatest?

The term for the reduction in the pressure head surrounding a pumped well is Drawdown.
Cone of Depression refers to the significant drop in the regional water table due to long-term pumping from multiple wells.
Stormwater Harvesting involves collecting run-off from structures or impervious surfaces for storage and later use.
Water Conservation is the practice of using less water more efficiently.
Water Footprint measures the total direct and indirect water use by an individual, community, business, or country.

Water is chemically composed of two elements: Hydrogen and Oxygen.
A water molecule consists of three atoms: two hydrogen atoms and one oxygen atom (H2O).

Water Scarcity describes a situation where people lack access to sufficient clean water or both.
Water stress occurs when the demand for water exceeds the available supply or when poor quality restricts its usage.
Areas with the greatest water stress typically include arid and semi-arid regions, as well as densely populated urban areas with limited water resources.
