Extractions: Water chemistry deals with all properties of the water and all the substances in the water. In an estuary like Narragansett Bay, the water and the substances in the water are always changing. The changes of the water are due to of the influence of both fresh water from the land and salt water from the ocean. Scientists monitor water chemistry in Narragansett Bay to determine the health of the bay. These are some of the water properties measured in Narragansett Bay.
Marine And Atmospheric Chemistry Carries out broadly based research on the chemistry of marine waters and the marine atmosphere, and maintains a highquality well-rounded graduate program leading to the MS and Ph.D. degrees. http://www.rsmas.miami.edu/divs/mac.html
Extractions: The Division of Marine and Atmospheric Chemistry (MAC) carries out broadly based research on the chemistry of marine waters and the marine atmosphere, and maintains a high-quality well-rounded graduate program leading to the MS and Ph.D. degrees. The Division's activities are focused on understanding the cycling and transport of chemicals in the oceans and atmosphere. A central theme underlying much of the research in the Division is to use our understanding of geochemical cycles in order to assess the impact of man's activities on global and regional scales. The Division has fifteen faculty members and a large support staff involved in research including postdoctoral fellows, technicians, and graduate research assistants. The Division occupies the newest building on campus, which houses a major part of the School's chemical research activity. There is research on collaborative projects with the other Divisions at the Rosenstiel School especially Meteorology and Physical Oceanography, Marine Biology and Fisheries, and Marine Geology and Geophysics. The faculty of MAC cooperate closely with the Chemistry Department , located on the main campus of the University of Miami. Faculty members from MAC teach courses in the Department and members from the Division and the Department frequently serve on student committees across departmental boundaries. The Division also benefits from its association with the
C3.org - Building Sustainable Water Systems Supported by its member companies, the Chlorine Chemsitry Council works together with the American Red Cross, Habitat for Humanity International, and educational organizations to benefit society. http://c3.org/partnerships/wrn/wrn_index.html
Extractions: Through the Water Relief Network® (WRN), the Chlorine Chemistry Council and its global industry partners help to bring safe drinking water to undeserved communities in developing countries. Working with the American Red Cross and other relief organizations, the WRN provides funding to purchase water disinfection chemicals and polyvinyl chloride (PVC) pipe to create permanent water distribution systems. In addition, WRN partnerships provide communities with improved access to and use of latrines, training in water supply management, and education in appropriate hygiene behavior. The Water Relief Network provided grants to fund water and sanitation projects in three Guatemalan villages. The projects, a collaboration between the WRN and the Red Cross, used chlorine disinfectants and PVC pipe to provide safe water supplies, sanitary latrines and improved hygiene for 728 people in 152 families. European industry associations, Euro Chlor and the European Council of Vinyl Manufacturers (ECVM), and the U.S. Chlorine Chemistry Council underwrote the WRN grants.

Extractions: Water and Ice Water has important effects on all biological systems. What makes water so unique are two very important properties. Water is a polar molecule Click for 3-D image A water molecule is formed when two atoms of hydrogen bond covalently with an atom of oxygen. In a covalent bond electrons are shared between atoms. In water the sharing is not equal. The oxygen atom attracts the electrons more strongly than the hydrogen.This gives water an asymmetrical distribution of charge. Molecules that have ends with partial negative and positive charges are known as polar molecules. It is this polar property that allows water to separate polar solute molecules and explains why water can dissolve so many substances. Water is highly cohesive Click for 3-D image The positive regions in one water will attract the negatively charged regions in other waters. The dashes show the hydrogen bond. In a hydrogen bond a hydrogen atom is shared by two other atoms. The donor is the atom to which the hydrogen is more tightly linked. The acceptor (having a partial negative charge) is the atom which attracts the hydrogen atom. Click here to view a movie of two water molecules.

The treatment process Much of our drinking water comes to us through the Sacramento River. Transforming that silty blend into clean drinking water is quite a process. The first thing we do is remove the solid particles in the water mostly silt mixed in during the water's long journey from the Sierra-Nevada mountains to one of our three water treatment plants: Rinconada, Santa Teresa or Penitencia. Removing solids Two clarifiers at Rinconada Water Treatment Plant We add special chemicalssuch as aluminum sulfateto the water that enters the clarifier. These chemicals, called coagulants, cause the solid particles to clump together. This process is called flocculation. Eventually, the clumps form a "sludge blanket." The solid clumps are far heavier than the water, so the blanket sinks to the bottom. As it does, the blanket works like a finely-meshed net to catch other smaller particles.

Mono Lake Chemistry As with most lakes, Mono Lake has a chemistry unique in all the world. Within Monoswaters are dissolved sodium salts of chlorides, carbonates and sulfates http://www.monolake.org/naturalhistory/chem.htm
Extractions: The waters are clear and very heavy. When still, it looks like oil, it is so thick, and it is not easily disturbed. The water feels slippery to the touch and will wash grease from the hands, even when cold, more readily than common hot water and soap. I washed some woolens in it, and it was easier and quicker than any "suds" I ever saw. . . I took a bath in the lake; one swims very easily in the heavy water, but it feels slippery on the skin and smarts the eyes. William Brewer California Geological Survey, 1863 NO WAY OUT GREAT BASIN CHEMISTRY A SOAP TO BE RECKONED WITH High concentrations of carbonates in Mono Lake make it very alkaline. The pH of Mono Lake is approximately 10 (this measure of alkalinity is roughly equivalent to household glass cleaner). Because of this high alkalinity, RECIPE You can make a close approximation of Mono Lake water at home or in the classroom: begin with one gallon of pure water, add 18 tablespoons of baking soda, ten tablespoons of table salt, 8 teaspoons of Epsom salt, and a pinch of borax or laundry detergent (in order to make
