Investigation Of Bacterial Contamination Of Water

Investigation of Bacterial Contamination of Water BACKGROUND OR INTRODUCTION The bag of this experiment was to investigate the extent of bacterial defilement of pissing taken from a variety of sources. in that location have been a lot of cases of large-scale bacterial contamination in the ult in the United States so it is primary(prenominal) to understand how this stop happen and what piss sources it can affect. It is a great deal difficult to get a line a detail source of bacterial contamination of piss, which is wherefore this experiment did not focus on that aspect. However, it can be qualifyd whether specific samples of piss are more or less bacterially dirty than others, as this experiment attempts to do. QUESTION Is water that is supposed to be dissipated actually cleaner than poolwater? HYPOTHESIS To determine my hypothesis, I used two logic and research. My research showed me that bacteria in pond water are actually heavy for the water and liv ing things in the water. This, and the fact that bacteria in our alcoholism water are clearly not red-blooded guide me to the hypothesis that water that is supposed to be clean (non-pond water) willing in fact be cleaner than pond water.

MATERIALS * trance attached appendix PROCEDURES * See attached appendix twain for explanations of steps and for explanatory diagrams RESULTS (a) entropy Collection & exhibit: (b) Data Processing & Presentation: In total, the 4 supposedly clean sources had 2 colonies, or an average of 0.5 each. In total, the 5 samples of pond water had 364 co lonies, or an average of 72.8 each. acc! ord to data collected from our samples, pond water is 145.6 times more bacterially contaminated than clean sources of water. CONCLUSIONS Clearly, my hypothesis that pond water would be more bacterially contaminated was proven to be catch up with by a huge mete in this experiment. pool water had more colonies of bacteria, was less clear, and had such(prenominal) more sedimentation. error could have...If you want to get a to the full essay, order it on our website: OrderCustomPaper.com
