Question

Dan took three samples of water from the creek behind his house once a month for the last six months. He tested the water and reported the results in the following data table.

Answer 1

i found another ope study member who asked the same question this is what their answer was

If the dissolved oxygen is lower than a 4.0 then that could be a problem, also the nitrates should be at least at 1.0 and 6 to 7 is way to high.Too much Fecal coliform can cause less oxygen. The turbidity seems concerning because the water is starting to become dirty.


If the water is in bad quality it can cause the plants and organisms around the creek to die.

It all sounds good, except you want to mention that the creek is possibly eutrophic and that there is a lot of life is there, but it has resulted in overconsumption from a large amount of phytoplankton and ultimately less life because there's not enough nutrients (it's depleted).

Answer 2

so do I put more than one because I thought it was only the Fecal coliform
I saw the Dissolved oxygen but it said Which water-quality indicators would be of concern in this situation so I thought you are to pick the greater problem

Answer 3

are you there

Answer 4

yes im here sorry i had to do something lol

Answer 5

My mom showed me it said indicators so know I know it is more than one thanks

Answer 6

a lot of it is actually alarming but i would go with fecal coliform bacteria it would be more than one that wuld be a problem i thought you could only choose one so i was trying to figure out the worst one lol

Answer 7

I don't know why they say the nitrates is too high because my chart says that 10 mg/L is Acceptable

Answer 8

im not sure :/ i suck at science

Answer 9

lol I'm ok but questions like this make want to ask for others opinions

Answer 10

thank you for your help
