Question

Which of the following is an indicator of good water quality?


High levels of nitrates

High levels of phosphates

All of the above

Zero turbidity @Mathematics

Answer 1

I dont like theses answers, but Zero Turbidity is the closest thing to a real answer, so I'll go with that.

Answer 2

kk thanks you

Answer 3

Zero turbidity

Answer 4

Are you good with science? @ZZ

Answer 5

Not that you asked me, but I'm an Environmental Scientist.

Answer 6

for the most part yes, and thats the one that makes the most sense the rest do not apply

Answer 7

Really? That's cool, so you both think that its zero turbidity? what is it exactly?

Answer 8

yes zero turbidity is right

Answer 9

Turbidity is a measure of how clear the water is.
0 turbidity means you can see the bottom of it (generally measured to 3 metres)

Answer 10

it in that case is a succi disk--which is how you measure it

Answer 11

Oh that makes sense, thank you or the clear explanation. Mind helping me with some other problems?

Answer 14

sure, ask away.

Answer 15

Which of the following is an action a Florida farm could take to reduce fecal coliform in nearby water supplies?
Answer

Get a water filter that traps algae before the water is recycled

Decrease the amount of animal waste that reaches the water supply

Decrease the amounts of pesticides sprayed on its crops

Increase the amount of fertilizers used on its crop fields



Would it be the third one?

Answer 16

Decrease the amount of animal waste that reaches the water supply
makes the most sense.

Creating a Riparian Corridor is actually the correct answer, lol

Answer 17

The question and the best answer kind of describe each other.
They want to reduce fecal cloriform (fecal like feces --or animal waste--)
And the answer: reduce animal waste reaching water supply

Answer 18

1st is right for more information go to

Answer 19

Izanagi that is not referring to the 1st answer, that is talking about creating a Riparian Corridor (which I mentioned is the best idea)... the filter they are talking about is an activated carbon sand filter that captures algae from stormwater/wastewater systems

Answer 20

Oh so the fecal cloriform is dealing with animal waste?

Answer 21

yes. it is a bacterium found feces.

Answer 22

Ah this is making more and more sense now, I'm sorry for so many questions, science is my weak point even though I really enjoy learning it. So i have only 2 questions left that I need help on.

Answer 23

hehe, no worries. Science can be a difficult beast to tackle.

Answer 24

Thank you so much :) and yes I agree, science very complex, but it's something we do need to learn, in order to understand the earth better. So here are the other 2 questions:


1.Which of the following is a common source of groundwater pollution?


Storm-drainage pipes carrying water with high levels of sediment

Oil dumping and oil spills

Landfills containing chemicals that drain into the soil

Dumping paper and plastics into a river


2.Which of the following is the most likely way for bacteria and viruses to enter a water supply?


Chemical fertilizers dumped into the water attract bacteria and viruses

Poor sanitation habits cause water to mix with sewage

Water from a burst dam sweeps particulate matter into a nearby river

Increased photosynthesis releases bacteria and viruses

Answer 25

For #1.
Storm-drainage pipes carrying water with high levels of sediment
Is what I would go with. Really, this as the dumping into a river are both common. But, sedimentation (adding of soils to water--increasing turbidity) is the 2nd most common type of pollution in ground water... so thats why I wanna go with that one.

For #2:
Poor sanitation habits cause water to mix with sewage
makes the most sense. Especially with farms, if they allow water to run directly from grazing lands for cattle/pigs/etc to go into a stream... or depending on where you live: Karst geology (underground springs, caves, waterways and such).

Answer 26

I dont know what science class you are in... but it makes me happy to see that this type of stuff is getting discussed in detail--I didn't learn about a lot of this stuff until I was in college (and studying Environmental Science) lol

Answer 27

Oh ok, but that is so cool that you are a scientist, how long have you been a scientist?

Answer 28

depends on how you want to define that, lol.
I started working professionally as a scientist about 9 months ago.
But, I started studying things and working for companies as a student or intern when I was a sophomore in college (about 5 years ago)... I just graduated from grad school with a Masters of Science in Ecology and Evolutionary Biology.

Answer 29

That's very interesting, what made you want to become a scientist? and do you believe in the Theory of Evolution then?

Answer 30

Well, actually I went to college to become a math guy--I didn't really know what I wanted to do, but I really loved math throughout school... but once I got fairly far in that and started looking at jobs, i realized... I dont want to sit behind a desk all day, lol
So, I switched to the sciences, at first biology, but then I went enviro because all my friends that were got to go on backpacking trips and fun stuff (which I also always enjoyed doing, camping, boating, hiking etc) So, I looked into that... Realized I could get a job like the one I have now, where I'm in charge of studying water quality of local rivers and streams and basically get to be outdoors 1/2 the time and the other 1/2 im doing math or chemistry in our labs (mostly testing the samples I take outdoors :D )

As for Evolutionary Theory. Yes I "believe" it. Actually, I've never met anyone that doesn't. I've met people that think they don't... but when I ask questions about it--they realize they actually dont have any problems with evolution, they have problems with other scientific theories (which are also true). Evolution, in its' most simple form says: you get some dna from mom and some dna from dad and even if mom and dad have more than one kid, they aren't genetically the same kid. I've never met anyone that didnt "believe" that... because it's true. In science, a theory has been tested (a lot) and has been found to be true (usually every time).

Answer 31

That is interesting that you have a different viewpoint on how life came about. I'm pretty sure many have also told you that they believe in god, no? I agree with science on many things, but I do believe in a creator/higher minded being, as did Einstein and Darwin. But it's always fun to learn other peoples view points :) Thank you for sharing that information.

Answer 32

As I mentioned, I've met lots of people that dont believe in other things, most notably abiogenesis. Which is the study of how life can form from non-living things. But, alas... belief in God doesn't prevent you from believing in things like that... Sure, it depends on which god you believe in, but I dont know of any religion that prevents someone from understanding and agreeing with Scientific thought. Literalist Christians do tend to believe that is a gap that cannot be connected... but since the literal interpretation of the bible is a relatively new (and American) fad, it doesn't really matter, lol.

Answer 33

Haha, well the bible has been here for thousands of years, sadly many people misinterpret it, but this conversation was fun, I hope we can talk more about this tomorrow or in the future, I like to learn more :) Thank you once again for all your help :D I really appreciate it.

Answer 34

No problem, ttyl.
