The other common way, electrochemical analysis uses what is already there to help identify the pollutant. As one should know, all atoms and molecules are surrounded by a bunch of electrons. When using the electrochemical strategy a small amount of electrodes are released into the concerned matter. A very sensitive reader attached to the substances will read the amount of voltage that is in the water.

I want to know if you swim in the water. And is it good to drink the water. And water does the water have in it.

Gravimetric is a very efficient way of measuring the condition of the water, all you have to do is weigh the pollutant on a very sensitive scale, that should be able to tell one-tenth of a milligram.

What kind of water quality data would you like to see during the next stage of the expedition?
do you dring the wather.do you take a bath with the wather.do you clen your close with the wather.do you close you house with the wather.

Most of the pollutants are classified under pH terms. pH measures how acidic or alkaline a solution is. 7 is the neutral (number) form on the scale. The solution is measured on a scale of 0-14, anything above 7 is alkaline, and anything below 7 is acidic.

We want to know how much pollution and chemicals are in the water.

Well I think that there might not be any difference in the water because the water from all of the fields hasn't washed down from the fields into the water. Unless it has been raining then I don't know what is going on!?!

you would have to do basic algabra

We found some things to test for:

1. Nitrates are a sign of pollution from farms and fertilizer. The minimum is 10 ppm of nitrates.

2. Phosphates are another sign of pollution.

3. Sewage levels are another sign.

4. Oxigen levels need to be tested. A minimum of 2 to 5 ppm is necessary for fish to surviv.

We would like to see water that is really badly polluted to show other people how we are hurting the Earth. We would also like you to get a very clean sample of water and compare it to the dirty water. We would hope the samples would show everyone how bad we are hurting the Earth.

We think it is inportant to test for:

1. Oxygen Levels- These are important for the fish to survive in underwater habitats.

2. Color- The color of the water could change with the amount of sewage blocking the river.

3. Garbage- Considering the space you are in the amount of garbage will change.

These could help you with your tests.

you could use basic algebra and have x as the poulutants

I think that you should calculate how much garbage is being thrown out at and average home,school,or any other place you stay, and see if that makes any difference
