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 pollution of pissing taken from a variety of sources. there have been a lot of cases of large-scale bacterial contamination in the ult in the United States so it is main(prenominal) to understand how this stop happen and what body of pee system sources it can affect. It is often difficult to get a line a unique(predicate) source of bacterial contamination of water, which is wherefore this experiment did non focus on that aspect. However, it can be qualifyd whether specific samples of water are to a greater extent or less bacterially soil 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 living things in the water. This, and the fact that bacteria in our drunkenness water are clearly not red-blooded lead me to the hypothesis that water that is supposed to be clean (non-pond water) exit in fact be cleaner than pond water.

MATERIALS * promise attached appendix PROCEDURES * See attached appendix both for explanations of steps and for explanatory diagrams RESULTS (a) entropy Collection & showing: (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 wa ter had 364 colonies, or an average of 72.8 ! each. concord 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 edge in this experiment. pool water had more colonies of bacteria, was less clear, and had lots more sedimentation. error could have...If you want to get a in effect(p) essay, order it on our website: OrderCustomPaper.com
