Catawba River Basin
Transcript of Catawba River Basin
So what does it look like?
Gaston, Lincolnton, Hickory, and Lenoir are all major cities near near the Catawba river basin.
What major river does the Catawba connect too?
It connects to Bodhiss river.
Where does it end?
What major cities are around this river basin?
It ends in Hickory N.C.
What are some common uses for the Catawba river?
Often people canoe, fish, walk trails, and because of the popular Catawba college people often visit the river, so it is good for tourism as well.
Why is up-wellilling and down welling important?
Upwelling is the process of where cold water at the bottom of the ocean is pulled from the bottom and brought to the top. If you hadn't already guessed, down welling is when water is taken from the top and pushed to the bottom. Upwelling brings nutrients from the bottom of the ocean and pushes them to the bottom. Down welling brings the other deeper water to the top, as fresh (I don't mean that it isn't salty) water for animals.
All about pH
pH measures the acidity of water. Water with a pH of less than 7 are said to be acidic and water with a pH greater than 7 are basic or alkaline.
How does temperature affect water?
The temperature of water can deeply affect it. Water that is out of range of the normal temperature can affect certain aquatic organisms. Even if the water changes just a little bit, it could be unnatural warming or thermal pollution. Lots of sunlight exposure can also affect the water.
Dissolved oxygen? Huh?
Dissolved oxygen is needed for aquatic life to survive because it is how the air gets into the water. This is caused from a process called aeration.
Nitrates and phosphates
Nitrates and phosphates affect water a lot, and they are found in aquatic environments, because they help maintain a stable metabolism and growth for plants and animals.
Turbidity is used to check the water's dirt or dirty particles in brackish water.
Bio-indicators are tiny organisms who change themselves to fit the environment and altered environmental conditions.
Point and non point pollution
No source or type of pollution is good. At least with point source pollution, you know where the pollution is coming from. With non point source pollution you don't know. This affects my river basin, because with pollution getting worse, you need to know where it is coming from to stop it.
How is water treated?
Aeration mixes water and air together, and during this process kills any chemicals or problems in the water, so certain reactions can occur in the water. Flocculation is another step in the water treatment process. Water is stirred around so that particles move around and stick to each other. Eventually they turn into clumps and can be easily removed from the water. Active carbon absorption is used in water where using a solid to remove a soluble solution from the water.
What government agency regulates water quality?
The EPA, or environmental protection agency, is in control of this.
When was the clean water act passed and what did it do?
The clean water act was passed in 1972 and it certifies that high levels of toxic substances aren't allowed in water.
When and why was the safe drinking act established?
The safe drinking act was passed 1974 and was issued to make sure there was safe drinking for the public.
