Chloride can be found in lakes by road salt runoff.
Chloride can be bad. If there is too much,
Target level for Lake Mendota is 45 mg/l or parts per million (ppm)
chloride is mainly caused by salt, which comes from salt runoff on the road

algae are single celled organisms. algae also produces oxygen.
some are good, some are bad
More algae in water means that more carbon dioxide is used from the atmosphere and more oxygen is released into the atmosphere

a simple nonflowering plant of a large group that includes the seaweeds and many single-celled forms. Algae contain chlorophyll but lack true stems, roots, leaves, and vascular tissue.

Algae goes through photosynthesis

Algae will block out all of the sun and eliminate the plants, the plants go through decomposition and take up all the oxygen, then the fishes dies

-How clear the water is
-You use the clarity tube
Transparency is how light passes through water

-Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae.

Nutrients can run off of land in urban areas where lawn fertilizers are used. Pet and wildlife wastes are also sources of nutrients.

Use a secchi disc or transparency tube

Define clarity: a way to measure water quality, it is a measure of how many particles are in the water

Define turbidity: The amount of suspended particles in the water

-Dissolved Oxygen is the level of oxygen in the water

-the colder the water the more oxygen is supposed to be in the water
Oxygen can be produced by plants.

How else does oxygen get into water? By photosynthesis, the air water interface and through wave action

# data[].attributes.body
The amount of heat that is in the water or air which is shown in numbers. The measurements are celsius or fahrenheit

-Plants use co2 in photosynthesis
-A colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis.

How does carbon dioxide enter water?
Through the air water interface.
Decomposition. at a certain point the air/ carbon dioxide infuses with the water. Dead animals decompose and turn into the water

7 is neutral
Anything less than 7 (<7) is acidic
Anything over 7 (>7) is basic
Stands for parts hydrogen
Most organisms adapt to a specific type of pH

Collect algae by scraping off of rocks, docks and any hard substrate. * Any free floating algae can be picked up in the collection container (bag/ bottle etc.) * If algae are attached to a plant, break off a piece and include in sample.
