|---|---|
| what does WQI stand for | Water Quality Index. |
| Clean water act 1972 | A law that keeps U.S. water clean and safe by controlling pollution. |
| Us safe water act 1974 | A law that keeps tap water safe to drink in the U.S. |
| diffrence between both acts | Clean water is about keeping the environment’s water clean. Safe water Focuses only on water people drink and makes sure it’s safe for humans |
| what is the primary sewage treatment process | A physical/mechanical process |
| primary treatment | Removes solids from wastewater. First step in cleaning wastewater, where solids and large particles are removed from the water. |
| ground water | Water that is found underground in soil and rocks. |
| how much of earth water is fresh water | 3% |
| why do algae blooms happen | to many nutrients |
| thermal pollution | hot water enters rivers or lakes and lowers oxygen levels, harming aquatic life. |
| why is fresh water a limited resource | because most of Earth’s water is saltwater, and only a small amount is usable freshwater. |
| water table | The top level of groundwater. |
| turbidity | How clear the water is |
| sediment pollution | Pollution from soil, sand, or dirt that pollute water |
| dirt, sand and silt are classified as what type of pollution | sediment |
| a hole dug or drilled into the ground to provide a supply of water | well |
| the worlds largest hydroelectric dam is the | Three gorges dam |
| the worlds largest knows aquifer | Ogallala aquifer |
| region of land that drains into a river | water shed |
| potable water | water that is safe to drink |
| point source pollution | Pollution from a specific place |
| toxic pollution | Pollution with harmful chemicals like pesticides, oil, or heavy metals. |
| bacterial pollution | Harmful bacteria in water that causes illness like E. coli or sewage. |
| desalination is | Removing salt from water |
| Permeability | How easily water can pass through a material like soil or rock. |
| effluent | Wastewater released into the environment usally from a factory or treatment plant |
| what does not make up earth surface water | aquifer |
| what is an aquifer | underground water stored in rocks or soil. |
| what do untreated (raw) sewage and fertalizers have in common | both add too many nutrients to water, which can harm it. |
| overuse of water for irrigation may lead to | Lowering of the water table |
| water is a what type of resource | renewable resource |
| in the wastewater treatment process what is the role of bacteria for water purification | Digesting organic matter |
| water footprint | amount of water used to make or produce something. |
| what is true about eutrophication in lakes and other bodies of water | It can cause to much algae to grow |
| renewable resource | Water that is recycled through the water cycle |
| Where is freshwater found | glaciers, groundwater,surface water |
| Where is freshwater found glacier | 69% |
| Where is freshwater found ground water | 30% |
| Where is freshwater found surface water | 1% |
| recharge zone | Area where water soaks into the ground to refill aquifers. |
| runoff | Water that flows over land into rivers, lakes, or oceans. |
| Freshwater wetland | Land saturated with water; includes marshes (grasses) and swamps (trees) |
| What are the main benefits of wetlands? | Flood control, water filtration, wildlife habitat. |
| nutrient pollution | too many nutrients, like nitrogen and phosphorus, enter water and cause harm to ecosystems. |
| Secondary treatment | using bacteria to remove waste from wastewater. |
| Bottled water is _____ regulated than tap water | less |
| How much water does the average American directly use at home (indoors and outdoors) every day? | 100 gallons |
| What accounts for the vast majority of water use and water pollution (percentage) worldwide? | agriculture |
| nonpoint sources pollution | Pollution from many diffuse sources (farms, streets, lawns). |
| What percentage of global water use goes to agriculture | 70% |
| What percentage of global water use goes to industry | 20% |
| What percentage of global water use goes to domestic | 10% |
| consumptive water use | Water removed and not returned |
| non consumptive water use | Water returned after use |
| gray water | Reused water from sinks, showers, or washing machines. |
| How many people lack access to clean, safely-managed drinking water? | 2.2 billion |
| A hundred million years ago, the Earth had: | the same amount of water it has today |
| Of potatoes, rice, poultry and beef, which uses the most water to provide 500 calories? | beef |
| what process is used to remove large particles from waste water during primary treatment | screening |
| Approximately what percent of Earth’s water is available as liquid freshwater | lesss than 1% |
| sludge | Thick, dirty solid waste that sinks to the bottom during wastewater treatment and must be removed. |
| septic tank | An underground tank that cleans dirty water from a house. |
| water mining | Water is being taken out faster than it can be replaced in many areas. |
| aqueduct | A system to move water long distances |
| Xeriscaping: | Landscaping with plants that need very little water. |
| Constructed wetlands: | Man-made areas with plants that clean wastewater naturally. |
| Biscayne Aquifer | Where Miami-Dade & Broward’s drinking water comes from |
| Why can water still be drained even though it’s renewable? | If it’s used faster than it can be replenished |
| Disinfection | Using chlorine or UV to kill remaining pathogens |
| Freshwater unsafe for drinking reasons | parasites, heavy metals, bacteria from sewage |
| surface water | -water that is found on the Earth’s surface, like in rivers, lakes, ponds, and streams. |
| recharge zone | where rainwater goes into the ground to fill underground water. |
| Where is Ogallala Aquifer located | great plains |
| Nutrient pollution example – | Too much fertilizer from farms causes green algae in a pond. |
| sediment pollution example – | Rain washes soil from a construction site into a river, making it muddy. |
| bacterial pollution example – | Raw sewage dumped into a lake can make people sick. |
| thermal pollution example | Hot water from a power plant flows into a river and kills fish. |
| toxic pollution example | Factory chemicals, like mercury or pesticides, get into a river and poison fish. |
| irrigation | Giving water to plants to help them gro |
| Reservoir- | a man-made lake that stores water. |
