Extractions: Who We Are What We Do Who Our Clients Are Government ... Conferences As part of a court-ordered management plan to clean up Boston Harbor, the Massachusetts Water Resources Authority (MWRA) has constructed the largest sewage treatment facility in the United States, including a new 9.5 mile ocean outfall. To document the environmental benefits of pollution abatement (i.e., recovery of Boston Harbor) and verify that discharge through the new offshore sewage outfall will not adversely impact Massachusetts Bay, MWRA contracted Battelle to research and monitor the effects of effluent discharges into Boston Harbor and Massachusetts Bay. The sewage outfall monitoring program, the most comprehensive monitoring program of its type in the nation, is multi-faceted and consists of seven major elements: water column studies of nutrient dynamics (including benthic fluxes and denitrification) and effects as related to eutrophication issues, benthic studies to assess the response of soft- and hard-bottom benthic organisms to effluent discharges

Goncharuk, NAS corresponding members O. D. Kurilenko, B. Yu. Kornilovich and Yu. I. Tarasevich); - analytical chemistry (NAS academician A. T. Pilipenko). The Institute was founded in 1968. In 1980 the Institute was named after academician A.V.Dumansky, the founder of colloid chemistry in Ukraine. Scientists of the Institute made a significant contribution to the development of the world and Ukrainian science. Their works were awarded with State Prizes of the Ukrainian SSR and the USSR, awards of the USSR Council of Ministers and prizes named after prominent scientists of the National Academy of Sciences of Ukraine. Since 1979 the journal «Khimiya i Tekhnologiya Vody» (Journal of Water Chemistry and Technology) has been issued. The journal publishes papers on fundamental and applied aspects of water protection, it is translated in full and distributed abroad by 'Allerton press'S.

Beginner FAQ: Water Chemistry In either case, you need to know enough about water chemistry to ensure that the Note GH, KH and pH form the Bermuda s Triangle of water chemistry. http://faq.thekrib.com/begin-chem.html
Extractions: Water in nature is rarely pure in the ``distilled water'' sense; it contains dissolved salts, buffers, nutrients, etc., with exact concentrations dependent on local conditions. Fish (and plants) have evolved over millions of years to the specific water conditions in their native habitats and may be unable to survive in significantly different environments. Beginners (especially the lazy) should take the easy approach of selecting fish whose needs match the qualities of their normal tap water. Alternatively, an advanced (and energetic!) aquarist can change the water characteristics to match the fish's needs, though doing so is almost always more difficult than first appears. In either case, you need to know enough about water chemistry to ensure that the water in your tank has the right properties for the fish you are keeping. Water has four measurable properties that are commonly used to characterize its chemistry. They are pH, buffering capacity, general hardness and salinity. In addition, there are several nutrients and trace elements. pH refers to water being either an acid, base, or neither (neutral). A pH of 7 is said to be neutral, a pH below 7 is ``acidic'' and a pH above 7 is ``basic'' or ``alkaline''. Like the Richter scale used to measure earthquakes, the pH scale is logarithmic. A pH of 5.5 is 10 times more acidic than water at a pH of 6.5. Thus, changing the pH by a small amount (suddenly) is more of a chemical change (and more stressful to fish!) than might first appear.

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

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.
