    Study Notes

    • Groundwater: water that infiltrates the ground surface and exists below it in a porous structure, consisting of water and air that fills pores underground.

    • Watershed: a division of drainage that feeds into a specific point, often in mountainous areas.

    • Aquifer: the underground soil or rock through which groundwater travels, separated from atmospheric pressure by an impermeable material.

    • Groundwater estimation: peak runoff flow rate (Q) can be estimated as a function of precipitation intensity, land use, and watershed area using the Rational Method.

    • Watershed pollution: major pollution sources come from within the watershed, with exceptions being pollutants from coal combustion.

    • Water scarcity: up to 60% of the human body is made up of water, and water is needed for energy production through the Energy Water Nexus.

    • Water scarcity challenges: 3,800 km3 of water is withdrawn every year, while 2,100 km3 is consumed, and demand for water has grown faster than population.

    • Major water-consuming countries: China, the United States, Brazil, Russia, Mexico, India, England, and France.

    • Water footprint: a measure of the water required to support human activities.

    • Water use by sector: agriculture, production of electricity, industry, and domestic use.

    • Water consumption in Kuwait: among the highest in the world, with a significant portion coming from desalination.

    • Kuwait water sources: distilled seawater and brackish water.

    • Kuwait water distribution system: consists of two networks, one for freshwater and the other for brackish water.

    • Kuwait water production: 9% from freshwater and 91% from brackish groundwater and desalination.

    • Groundwater production in Kuwait: 503 L/day/capita in 2002, with MEW and KOC providing 9% of the annual water supply.

    • Brackish groundwater consumption in Kuwait: 1135.6 gallons/day per person.

    • Kuwait water scarcity: population increase is straining the water supply.

    • Water scarcity solutions: focus on efficient use, desalination, and reuse.

    • Two types of water filtration: Granular Media Filtration and Membrane Filtration

    • FARAH M. AL-DUWEESH discusses advanced water filtration technologies

    • Membrane Process, a large-scale filtration technology, uses a series of semipermeable filters to purify water, with over 20,000 plants operating worldwide by 2007

    • Membrane filtration types: Microfiltration, Ultrafiltration, Nanofiltration, and Reverse Osmosis

    • RO is the tightest filtration barrier, and is used for desalination

    • Both Kuwait and the U.S. have a history of desalination, with the first plant in Kuwait in 1951 and the first plant in the U.S. in 1962

    • Kuwait has eight desalination plants, extracting most of its water from brackish groundwater in the southwest and surface water in the north during rainstorms

    • Desalination is energy-intensive and consumes a significant amount of water, with the power plant and desalination network in Kuwait having capacities of 16,095 MW and 2 × 106 m3/day, respectively

    • Other water filtration technologies include the Adsorption Process, using Granulated Activated Carbon (GAC) to remove organic and inorganic constituents and dissolved gases, and the Desorption/Stripping process, using a gas stream to remove gases from the liquid stream.

    • Desalination is an expensive but growing water treatment technology, providing around 1% of the world's drinking water, and mainly located in the Middle East and North Africa.

    • Iceland, Greenland, Switzerland, Sweden, Australia, Denmark, Canada, Finland, and Norway have the best potable tap water in the world, while Uganda, Ethiopia, Nigeria, Cambodia, Nepal, Ghana, Bhutan, Pakistan, Congo, and Mexico have the worst.

    • Affluent countries have the energy to reclaim and reuse their water through wastewater treatment, while other countries still struggle with access to energy and water.
