APES Ch 14 - Water

Quiz yourself by thinking what should be in each of the black spaces below before clicking on it to display the answer.
        Help!  

Question
Answer
Point source   a direct location from which pollution is produced that you can point to  
🗑
nonpoint source   a diffused area that produces pollution; cant point to one source  
🗑
Sewage: primary treatment   remove solids  
🗑
Sewage: secondary treatment   digestion of sludge by bacteria, requires O2, captures methane as energy  
🗑
Sewage: tertiary treatment   chlorine, ozone, or UV light kills bacteria, water exits to ecosystem  
🗑
Oceanic dead zones from nutrient pollution   Fertilizers runoff into bodies of water creating eutrophication leading to dead zones  
🗑
“oxygen sag curve”   In bodies of water with sewage, decomposers come in because they like the nutrients in sewage & perform cell respiration, taking all oxygen from water making it hypoxic. Only anaerobic organisms survive.  
🗑
Sources of heavy metals on groundwater/drinking water   Lead found in pipes and other materials of older construction, arsenic occurs naturally through mining and industry, mercury occurs through burning coal  
🗑
Impacts of heavy metals on groundwater/drinking water   Leads to damage to the brain and nervous system, slowed growth and development, learning and behavior problems, and hearing and speech problems  
🗑
Causes and impact of increased sediment in waterways   Cause water to become darker leading to less photosynthesis, increased temperatures and can clog gills of aquatic animals  
🗑
What is Eutrophication? How does it lead to die-offs?   A phenomenon in which a body of water becomes rich in nutrients; causes rapid growth of algae which eventually dies, causing the microbes to increase the BOD  
🗑
“Hypoxic”- What does this mean for a body of water   Low concentration of oxygen  
🗑
Eutrophic   highly productive, with lots of plants/algae and less clear water  
🗑
Oligotrophic   nutrient-poor, very few plants and very clear water  
🗑
What is thermal pollution? Sources?   Non Chemical water pollutants that occur when human activities cause a substantial change in the temperature of the water (factories taking in cold water and releasing hot water back)  
🗑
Thermal pollution impacts on dissolved oxygen   Warmer water has less dissolved oxygen  
🗑
Noise pollution   Sounds emitted by ships in submarines  
🗑
Impact of noise pollution on ecosystem   Interferes with animal communication  
🗑
Clean Water Act   Issued water quality standards that defined acceptable limits of various pollutants in U.S. waterways  
🗑
Safe Drinking Water Act   Establishes maximum contaminant levels for 77 different elements or substances in both surface water and groundwater  
🗑
