Water Quality Vocab
Stack #26672
| Question | Answer |
|---|---|
| Aerobic | Living in a enviroment that contains atmospheric or dissolved oxygen. |
| Anaerobic | Living in an enviroment without atmospheric or dissolved oxygen. |
| Buffer | A substance that slows changes in pH, either from acid to alkaline or alkaline to acid. |
| Brackish water | Water that is a mixture of fresh water and salt water. |
| Carcinogen | A sunstance that causes cancer. |
| Clean water | 1)Water that is clean enough to be used for a specific purpose, such as cooking, swimming or drinking. 2) Water that satisfies the requirements of certain regulations, such as the Federal Clean Water Act and Safe Drinking Water Act. |
| Cryptosporidium | A parasite that lives in water and causes a disease called "cryptosporidiosis" in people. This disease can be fatal to people with weakened immune systems. |
| Disinfection | The killing of waterborne microorganisms in the water. Common forms of water disinfection include boiling and treating with chlorine, chloramine or ozone. |
| Dissolved Oxygen (DO) | DO is a measure of the amount of oxygen dissolved in water. Healthy levels are seential for a thriving ecosystem and high-quality drinking water. Water receives oxygen from plant photosynthesis and turbulence (mixing with air). |
| Distilled water | Water that contains no minerals or impurities. |
| Diurnal | Taking place during a one-day time period. In most cases, diurnal refers to the full 24-hour day. In some cases, it may refer only to the hours of daylight, in which case, it is the opposite of "nocturnal." |
| Ecosystem | A natural system where the health and well-being of any single element depends on the health and well-being of the other elements. |
| Eutrophication | A set of physical, chemical and biological changes caused by excess nutrients in the water. These nutrients stimulate plant growth and algal blooms that deplete the supply of dissolved oxygen and eventually kill aerobic life in the water. |
| Filtration | Screening out the organisms and solids in water. The size of the filter's openings determines the size of the particles that are filtered out. |
| Fresh water | Water that is not salt water or brackish water. Technically, it has a dissolved solid level of less than one part per thousand.The term fresh water does not denote whether water in drinkable(potable) or contaminated,or which specidic minerals it contains. |
| Groundwater | Water that exists in underground aquifers.Groundwater can either flow to the surface through springs, or it can be tapped from the surface through wells.Groundwater tends to be clear and clean because it has been filtered through layers of sand and rock. |
| H2O | The chemical constituents of pure water: two atoms of hydrogen and one atom of oxygen. Pure H2O is seldom found in nature, and then only for a few moments because chemicals and gases dissolve readily in water. |
| Hardness | The total amount of calcium and magnesium dissolved in water. |
| Heat capacity | The ability of a sucstance to hold heat energy. |
| Microorganisms | Organisms so small they can only be seen through a microscope. |
| Nutrients | Nitrogen and phosphate molecules in water that provide nourishment to algae and other plants. |
| Organic material | Material that comes from living or dead organisms: leaves, twigs, insects, animal waste (feces and urine), etc. |
| Part per million(ppm) | A measurement of the concentration of substances(minerals,salts,pollutants).One part per million means that there is one unit of a substance for every million total units.For example,if you were one person in a population of one million people, you would |
