  2. KUALITAS AIR It’s a simple fact - we can’t live without water. People use it every day for drinking, washing and cooking, as well as for irrigating crops and generating electricity. Water is also essential for maintaining the health of natural systems, which in turn support us. There are many actions to take to use water wisely at home and in the garden to help secure water for our future. Sumber: http://www.livinggreener.gov.au/water)

  3. KUALITAS AIR Kualitas air mencerminkan karakteristik kimia, fisika dan biologis air. It is a measure of the condition of water relative to the requirements of one or more biotic species and or to any human need or purpose. It is most frequently used by reference to a set of standards against which compliance can be assessed. The most common standards used to assess water quality relate to health of ecosystems, safety of human contact and drinking water. The parameters for water quality are determined by the intended use. Work in the area of water quality tends to be focused on water that is treated for human consumption, industrial use, or in the environment.

  4. KUALITAS AIR AMBIENT Environmental water quality, also called ambient water quality, relates to water bodies such as lakes, rivers, and oceans. Water quality standards for surface waters vary significantly due to different environmental conditions, ecosystems, and intended human uses. Toxic substances and high populations of certain micro-organisms can present a health hazard for non-drinking purposes such as irrigation , swimming , fishing, rafting , boating, and industrial uses. These conditions may also affect wildlife, which use the water for drinking or as a habitat. Modern water quality laws generally specify protection of fisheries and recreational use and require, as a minimum, retention of current quality standards.

  5. Parameter kualitas lingkungan air tawar Freshwater environmental quality parameters are the natural and man-made chemical, biological and microbiological characteristics of rivers, lakes and ground-waters, the ways they are measured and the ways that they change. The values or concentrations attributed to such parameters can be used to describe the pollution status of an environment, its biotic status or to predict the likelihood or otherwise of a particular organisms being present. Monitoring of environmental quality parameters is a key activity in managing the environment, restoring polluted environments and anticipating the effects of man-made changes on the environment.

  6. KONSUMSI MANUSIA Contaminants that may be in untreated water include microorganisms such as viruses and bacteria; inorganic contaminants such as salts and metals; organic chemical contaminants from industrial processes and petroleum use; pesticides and herbicides; and radioactive contaminants. Water quality depends on the local geology and ecosystem, as well as human uses such as sewage dispersion, industrial pollution, use of water bodies as a heat sink, and overuse (which may lower the level of the water). In urbanized areas throughout the world, water purification technology is used in municipal water systems to remove contaminants from the source water (surface water or groundwater) before it is distributed to homes, businesses, schools and other users. Water drawn directly from a stream, lake, or aquifer and that has no treatment will be of uncertain quality. Diunduh dari: http://en.wikipedia.org/wiki/Water_quality ……………… 28/11/2012

  7. PENGGUNAAN AIR: DOMESTIK DAN INDUSTRI Dissolved minerals may affect suitability of water for a range of industrial and domestic purposes. The most familiar of these is probably the presence of ions of calcium and magnesium which interfere with the cleaning action of soap, and can form hard sulfate and soft carbonate deposits in water heaters or boilers. Hard water may be softened to remove these ions. The softening process often substitutes sodium cations. Hard water may be preferable to soft water for human consumption, since health problems have been associated with excess sodium and with calcium and magnesium deficiencies. Softening may sacrifice nutrition for cleaning effectiveness Diunduh dari: http://en.wikipedia.org/wiki/Water_quality ……………… 28/11/2012

  8. Water Quality Indicators We will now take a look at the water quality indicators. Diunduh dari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  9. ALKALINITY Alkalinity refers to the water’s ability to neutralize acids. Alkalinity is produced by minerals such as limestone. Limestone is a type of ocean sediment composed of calcium carbonate. Diunduh dari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  10. Limestone bedrock areas often have caves and sinkholes, known as Karst. Water with low alkalinity is usually acidic. Diunduh dari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  11. Ammonia Ammonia is produced by the decay of organic matter and animal waste. Ammonia is toxic to most aquatic life, especially at high pH. Bacteria readily convert ammonia to nitrate. (a plant nutrient) Diunduh dari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  12. Ammonia Ammonia is a form of nitrogen and part of the Nitrogen Cycle. Diunduh dari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  13. BACTERIA Most bacteria are important in nutrient and other organic cycles. Excess nutrients cause algal blooms. As algae die and decay, the high bacterial load rapidly consumes dissolved oxygen. Diunduh dari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  14. Certain types of bacteria indicate animal and human waste pollution. Escherichia coli are coliform bacteria found in the intestines of warm-blooded organisms. Most strains are harmless but one E.coli strain can cause severe diarrhea and kidney damage. Diunduh dari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  15. Oksigen Terlarut Dissolved oxygen is a product of photosynthesis and diffusion. The warmer the water, the less oxygen it can hold. Diunduh dari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  16. Oksigen Terlarut Most organisms need at least 5 or 6 ppm of oxygen in order to survive. Even cold water rarely contains more than 15 ppm. Summer is often a time of oxygen stress for aquatic organisms. Diunduhdari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  17. Konduktivitas Conductivity measures the water’s ability to conduct an electrical current. Pure water is a poor conductor. Diunduh dari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  18. Konduktivitas The addition of dissolved solids, especially salts, increases the conductivity of water. Electrical current is measured using a conductivity meter. Diunduh dari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  19. Kesadahan Hardness refers to the concentration of calcium and magnesium in water. Hard water has high concentrations of these elements. Soft water has low concentrations. Water hardness often originates from limestone. Diunduh dari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  20. Nitrat Nitrate is a primary plant nutrient. Nitrate is water soluble and moves easily from surface to groundwater. Excess nitrate causes algal blooms that reduce water quality. Diunduh dari: step.nn.k12.va.us/science/envsci/ppt/Water_Quality_Indicators.ppt‎

  21. Under normal conditions, the nitrogen cycle keeps the amount of available nitrogen in balance with the demands. However, excessive use of fertilizers and nutrient rich sewage release have created a surplus of nitrate. The result is eutrophication from excess algae and bacteria with reduced dissolved oxygen.

  43. INDICATOR OF WATER Biological Indicators/ assessment Ephemeroptera Plecoptera Trichoptera Escherichia Coli or E.Coli or E.coli Coliform Biological monitoring metrics have been developed in many places, and one widely used measure is the presence and abundance of members of the insect orders Ephemeroptera, Plecoptera and Trichoptera (EPT). EPT indexes will naturally vary from region to region, but generally, within a region, the greater the number of taxa from these orders, the better the water quality. EPA and other organizations in the United States offer guidance on developing a monitoring program and identifying members of these and other aquatic insect orders. Individuals interested in monitoring water quality who cannot afford or manage lab scale analysis can also use biological indicators to get a general reading of water quality. One example is the IOWATER volunteer water monitoring program, which includes a benthic macroinvertebrate indicator key. Diunduh dari: ……………… 28/11/2012

  44. WATER QUALITY INDEX A water quality index provides a single number (like a grade) that expresses overall water quality at a certain location and time based on several water quality parameters. The objective of an index is to turn complex water quality data into information that is understandable and useable by the public. This type of index is similar to the index developed for air quality that shows if it’s a red or blue air quality day. The use of an index to "grade" water quality is a controversial issue among water quality scientists. A single number cannot tell the whole story of water quality; there are many other water quality parameters that are not included in the index. The index presented here is not specifically aimed at human health or aquatic life regulations. However, a water index based on some very important parameters can provide a simple indicator of water quality. It gives the public a general idea the possible problems with the water in the region.

  45. BAKU MUTU AIR & PELAPORANNYA 1. WHO Guideline World Health Organisation (WHO) guideline for Drinking Water Standards. 2. ICMR Standards ICMR Standards for Drinking Water. 3. International standards or ISI Satandards Water quality regulated by the International Organization for Standardization (ISO) is covered in the section of ICS 13.060, ranging from water sampling, drinking water, industrial class water, sewage water, and examination of water for chemical, physical or biological properties. ICS 91.140.60 covers the standards of water supply systems. Diunduh dari: ……………… 28/11/2012

  46. KRITERIA KUALITAS AIR Section 304(a)(1) of the Clean Water Act requires us to develop criteria for water quality that accurately reflects the latest scientific knowledge. These criteria are based solely on data and scientific judgments on pollutant concentrations and environmental or human health effects. Section 304(a) also provides guidance to states and tribes in adopting water quality standards. Criteria are developed for the protection of aquatic life as well as for human health.  Diunduh dari: http://water.epa.gov/scitech/swguidance/standards/criteria/index.cfm……………… 28/11/2012

  47. KEHIDUPAN AKUATIK Aquatic Life criteria lists chemical concentration goals to protect surface water for aquatic life use. Biological criteria are based on the numbers and kinds of organisms present and describe the biological condition of aquatic communities inhabiting surface waters. Nutrients are substances used by living things that promote growth (e.g., nitrogen and phosphorus). We are developing nutrient criteria to prevent over enrichment in surface waters of the U.S.A.

  48. KESEHATAN MANUSIA Human Health includes technical information and guidance on surface water, drinking water and microbials. Microbial (Pathogen) criteria are used to protect the public from exposure to harmful levels of pathogens in ground and surface waters, food sources, and finished drinking water. Recreational Criteria protect people who swim and play in coastal recreational waters from exposure to pathogens. We held an Experts Scientific Workshop to help map our future directions.

  49. INDEKS KUALITAS AIR DAN INDIKATORNYA The integrity of an ecosystem is typically assessed through its ability to provide goods and services on a continuous basis. Together with the air we breathe, the provision of clean water is arguably the most fundamental service provided by ecosystems. Yet, human activities have fundamentally altered inland water ecosystems and their catchments. As a consequence species dependant on inland waters are more likely to go extinct, and future extinction rates of freshwater animals could be up to 5 times higher than for terrestrial animals. Water quality refers to the physical, chemical and biological characteristics of a water body. These characteristics determine how and for what water can be used and the species and ecosystem process it can support.
