Before treatment we had to measure the water twice and came up to 197 mL. The water was a heterogeneous mixture when we started with it. The water smelt like vinegar, oil and salad dressing which was a physical property. the water was less dense then the oil. you can tell cause the oil was floating on the top. It was not transparent and there were bubbles at the top as well as a thick layer of oil. After the first step of purifying we measured the water once and came out with 97 mL. After we were done the oil water came to 49.23857868%. Most of the oil had subsided after we disposed of it and the water was clearer. The solid dirt at the bottom was no longer visible and there were no longer 2 layers to the water. The color of the solution was now a lighter brown. After the next step of purification there was only 71 mL of water left. All the specks of dirt disappeared by this time and we added sand and gravel solution. after we added the sand the percentage was 73.19587868%. We separated the sand from the liquid it physical changed into a greener color now. We added the element of charcoal to the mixture and the water was completely black. The charcoal went through suspension. The water went through the charcoal and the charcoal rid the water of odor and made the water more clear. After filtration the after turned out to be semi-clear it was a little foggy. It has a tint of a green color to it. the percentage of the water after filtration was 26.395939086% There was not nearly as much water as we started out with we came out with a final result of 52mL of //clean// water. This process can be identified as a chemical and physical change of the water and is now a homogeneous mixture.

% oil water= 49.23857868 % after sand= 73.195876289 % after filtration= 26. 395939086
