2

Multiple Select

Which of these are healthy (check all that apply)

1

low turbidity

2

low DO

3

PH of 6

4

low temperature

3

Turbidity and Color

There is high turbidity in the ocean and, the water has turned green.


4

Open Ended

what causes high turbidity

5

Dissolved Oxygen

In this area of the ocean there is low dissolved oxygen resulting in the death of organisms.


6

Multiple Choice

low DO = what

1

low bioindicators

2

pollution

3

Dababy

4

Lebron James

7

Water Temperature

The temperature of the water is high especially in the summer months the highest being August.


8

Bio-Indicators

Fish and other ocean organisms have died showing poor water health due to low DO levels.

9

PH

The water has an acidity of 7 


10

Pollution

There is low point source pollution and high non-point pollution caused by runoff from farms.


11

Main Problem

With runoff coming from farms we have nitrates causing an Algae Bloom which in itself causes high turbidity, high water temperature and, low dissolved oxygen.


12

Solutions

There are a few solutions we propose a law to prevent farmers from using nitrates on their fields which led into the ocean this would be prevention which is our best option. To remove nitrates from water would take large scale reverse osmosis which would be expensive and take a lot of time

Poll

Do you think this solution will work

yes
