Which of the following is true of sewage treatment plants in the United States? They release wastewater before solids are removed from the sewage. They use stormwater runoff to assist in the treatment process.
What causes the death of game fish in cultural eutrophication quizlet?
An excessive richness of nutrients in a body of water, frequently due to runoff from the land which causes a dense growth of plant life and death of fish from a lack of oxygen.
Which potential source of water pollution is a nonpoint source quizlet?
They are : parking lots - grease, toxic metals, and sediments that collect on impervious surfaces are a major source of nonpoint pollution.
How do sewage treatment plants create a solid waste problem?
solid waste particles: either when flowing water travels through a grate that blocks large solids from passing or when the particles settle out into a settling pond. Two common methods of disposing of solid waste from sewage treatment plants are transporting it to a landfill or spreading it onto agricultural lands.
Which of the following is an effective alternative to chlorine for disinfecting wastewater in a municipal treatment plant?
BromineBromine is a heavy red-brown liquid that is a viable alternative to chlorine for water disinfection when water is released into the environment. Because ammonia is present in sewage water, bromamines are produced through injection of bromine and are even more effective than chloramines.
What is meant by eutrophication and how is it influenced by farm practices involving phosphorus quizlet?
What is meant by eutrophication, and how is it influenced by farm practices involving phosphorus? Eutrophication is an extra nutrient to stimulate algae growth and causes oxygen depletion and increases fish kills. For farming practices phosphorus can leach or runoff and cause problems in freshwater systems.
What is cultural eutrophication and how are the organisms living in the lake effected?
Harmful algal blooms, dead zones, and fish kills are the results of a process called eutrophication — which occurs when the environment becomes enriched with nutrients, increasing the amount of plant and algae growth to estuaries and coastal waters.
Which of the following processes is involved in eutrophication quizlet?
Eutrophication is the process by which fertilizers in a lake build up over time & cause an increase in algae. This can cause lakes to become grassy meadows. The speed of this process is increased by lawn fertilizers, & dog & geese waste.
What are point and nonpoint sources?
Point and Nonpoint Pollution Sources Pollution originating from a single, identifiable source, such as a discharge pipe from a factory or sewage plant, is called point-source pollution. Pollution that does not originate from a single source, or point, is called nonpoint-source pollution.
Which is a nonpoint source of pollution?
Nonpoint source pollution can include: Excess fertilizers, herbicides and insecticides from agricultural lands and residential areas. Oil, grease and toxic chemicals from urban runoff and energy production. Sediment from improperly managed construction sites, crop and forest lands, and eroding streambanks.
What is the difference between point source pollution and nonpoint source pollution quizlet?
Point source pollution has a known and specific location. Nonpoint source pollution does not have a specific point of origin.
