Analysis

Examining the water before the purification steps from my point of view it looked very dirty with multiple substances in it, also it had a horrible smell almost to the point where you couldn’t smell it without gagging. After our 1st step of purification, which was oil treatment the water still looked very murky but not nearly as dirty before we completed the first step. After the 2nd step, which was sand filtration and 3rd step, which was charcoal treatment, the water became almost very clear but still showed signs of impurity. Finally after step 4, which was filtration treatment the water looked just as pure as a bottle of water a person would drink. If one of these steps were missed the water would still be cloudy and look impure. In each step of this lab many things were removed to make what we have at the final step. First the oil was removed in the first step using the pipe, and then in the next step we mixed our water with sand and gravel. This was in order to get rid of the material that was floating around which in our eyes looked like pepper, after that we mixed the rest with water with the charcoal, and this was to remove the yellow color and other material. Our group was able to retain a decent amount of water however because of the materials given it has taken awhile to get this water. The first step with filtering it with gravel/sand took almost no time. The second step has taken a few days, the charcoal filtering. We have kept a decent amount of water. Overall I believe that our group was able to efficiently gain water, with the tools we were given.
