Dependence of man on the environment Essay

Three essays were conducted during week two. The rootage was to determine how many contaminates that we say into our weewee supply leave alone r distributively our ground piss. The shutdown that I arrived at was, that there argon withal large remnants of contaminates in the ground weewee system supply after it has had a chance to be passed through with(predicate) lubricating oil. We emulated this affect by victimization smaller totalitys of contaminates such as oil, vinegar and laundry purifying. Put them in a smaller amounts of irrigate supply and indeed passed them though begrime. Introduction In the introduction, I entrust list the problems with our worlds weewee sources. Contained in the articles written by The graphic Resources Defense Council. body of water. These sources go on to land problems that we ar facing as a population with our water calibre. Some of these problems ar large amounts of water waste, the large cities that are going to face a tem per change that get out(a) alter their dependency on water. They also note that grubby water is the worlds largest wellness risk and it continues to threaten the quality of purport and the public health in the unify States. The first problem is that people shamt know how important having corking water is until its no interminable easily accessible for them. When people give way more informed about the problems that we are facing and canvasament face genuinely soon as a society. We rump take certain steps to chasten to prevent it and to ensure our quality of vitality not altogether stays the same, alone advances.Little can be accomplish by one, but if we work unneurotic and try to conserve and keep our water clean, it can last much longer. The fair game of this experiment is relatively simple, to educate on how much we affect our environment by the actions we take and what we can do to improve our habits to ensure that our water supply will last much longer and flummox good quality. It also has the purpose to allow people know that their actions dont just affect them or only the people that they live around it also affects the environment and the animals that inhabit it. During the experiment of the Water Quality and Contamination my hypothesis were The crude hypothesis was that if there is oil in the surface water then, I study when the water is passed through soil it will be able to filter out the oil before it r all(prenominal)(prenominal)es the groundwater. The hypothesis for the vinegar hypothesis was if there is vinegar in the surface water then, I call up that when passed through soil it will still remain in the groundwater.My laundry purifying hypothesis was if there is laundry detersive in the surface water then, when it is passed through soil it will still sacrifice traces of laundry detergent in the groundwater. The contiguous experiments hypothesis was that victimization particular chemicals and methods of filtrat ion, we should be able to have most of the contaminates that are in the groundwater. This was the experiment that involved disparate methods of Water Treatment. The utmost experiment pertained to the drinking water quality and my hypothesis was that angle water will contain the most contaminates because of its path and transcendental condition. The bottles of water are in a more sterile environment. The Dasani water is set and Fiji comes from a natural spring. The treated water (Dasani) will have the least amount of contaminates. Materials and MethodsThe first experiment that was conducted employ soil, different beakers, woody stir sticks, vegetable oil, vinegar, liquefied laundry detergent, water, cheesecloth and moves. I poured water into from individually one of the first 4 beakers, and then put vegetable oil, vinegar and laundry detergent in respectively. I stirred them with the woody stir sticks and utilize the cheesecloth to line the funnel and put soil in and po ured each of the different contaminates through, replacing the soil and cheesecloth each time. The atomic number 16 experiment involved beakers, soil, cylinders, sand, brown coal, gravel, woody stir stick, alum, funnel, cheesecloth, bleach, stopwatch and water. I added soil to a beaker and put water with the soil and mixed them with two beakers 15 times. I divvied some on the contaminated tooth root into a new beaker and added alum to it. I stirred the mixture with a wooden stick for 1-2 minutes and then permit it sit for 15 minutes. I lie a funnel with cheesecloth and layered sand, charcoal and gravel into the cheesecloth.I poured the clean tap water through the filter and reiterate 4 times. I poured of the contaminated water into the funnel and let it filter for 5 minutes. I annotated the smell and compared to the mixture in step 3. I added a a couple of(prenominal) drops of bleach and stirred the combination for 1 minute. I then compared and annotated the now filtere d water to the initial contaminated water. The final research laboratory contained Dasani bottled water, Fiji bottled water, Ammonia running stripes, Chloride try on strips, 4 in 1 discharge strip, orthophosphate test strips, iron test strips, beakers, marker, stopwatch, Parafilm, pipettes, crucify packets of reducing powder and tap water. I labeled each of the beakers and poured Dasani, Fiji and tap water in each of the three beakers. I gathered the ammonia test strips and fixed in the water and moved them up and down vigorously for 30 seconds each, I held each pad level for 30 seconds to get a enjoining. I did this 2 more times for each of the beakers. I then retrieved the chloride test strips and immersed the reaction zones in each of the three beakers one at a time for 1 second each. I shook off the inordinateness liquid and determined what color the test strip was. I then used the 4 in 1 test strip and dipped in each of the beakers again, one at a time, for 5 seconds an d wiggled anchor and forth.I briskly outside the superabundance water and waited 20 seconds to read the results. I then used the phosphate test strip by dipping in each of the beakers signally for 5 seconds and then removed(p) and held horizontal for 45 seconds, leaving the excess water on the test strip and recorded the results. Finally, I used the Iron test strip and removed 70 ml of water from each beaker and tested 30 ml of each of the three beakers. I added one track packet and covered with parafilm and shook the beaker for 15 seconds. I removed and dipped the test pad into the sample and moved it back and forth under the water for 5 seconds. I removed and shook the excess water off and tested and compared 10 seconds later.
