Cleaning Water By Ben, **// __Claudia__ //**, Eva, Andre Supplies Alum Filter paper Funnel Charcoal, Sand, Gravel Funnel Beakers Strainer/slotted spoons Bleach we took a first look at our water. it was a swampy green color and not very clear. it was an unusual smell of ovaltine and vinegar. it had a pH of 4. it had a negative glucose test and it had oil. after we cleaned it it was clearer but the color
 * 1) Write up the actual steps you performed to clean the water.vg
 * 2) Write up your observations. Be very specific as to what the water looked and smelled like after each step!
 * 3) Answer these questions:
 * 4) What were you not able to remove?
 * 5) How might you be able to remove it from the sample?
 * 6) How was your treatment process like that of the Sweetwater plant?
 * 7) How was your treatment process different?

The first thing we did was do a chemical check. Then we added alum to the dirty water. While adding the alum one of us stirred the dirty water to get the alum to mix with it better. then after all that we used a funnel to filter the water. We got a funnel paper and poured the water through that piece of paper. After that we used the charcoal, sand, and gravel, method. We then did another chemical check so we could compare the before and afters.

Somethings we couldn't take out was the smell of vinegar. A way we could've taken the smell out is by adding bleach to the water. Our water treatment was similar to the Sweetwater treatment because the water goes through similar processes. the difference between the sweetwater treatment and our water treatment is that it is the sweetwater treatment is more professionally done.

Observations- when we added the alum the water got a little darker. it got even darker after we stirred it some more. after we filtered it with the funnel it had lost some of the dirt so it turned into more of a yellow-ish color. after we used the filter paper it got a little clearer but was still sora yellow. but once we ran it through the charcoal, sand, and gravel it was fully clear but had the oil on top.

When we first got the water it was green, it smelled like ovaltine and viniger, it had lots of oil floating ontop, and there were chunks of white stuff and dirt. We pu i through a peice of filter paper and funnel to get all the chunks of stuff out. When we poured the water through charcoal, sand, and gravil it turned out clear but still with the smell of ovaltine and viniger and it still had oil. we tested the water in the end and we got pH 4.
