Dependence of man on the environment Essay

Three experiments were conducted during week two. The first was to determine how many contaminates that we put into our body of piss system supply lead reach our ground piss. The conclusion that I arrived at was, that at that place argon unflurried large remnants of contaminates in the ground pee supply after it has had a chance to be passed through grunge. We emulated this affect by using littler amounts of contaminates such as oil, vinegar and laundry detergent. Put them in a smaller amounts of water and past passed them though soil. Introduction In the introduction, I will list the problems with our worlds water sources. Contained in the articles write by The Natural Resources Defense Council. Water. These sources go on to state problems that we argon confront as a population with our water tint. Some of these problems argon large amounts of water waste, the large cities that are going to face a climate change that will alter their dependence on water. They also note that dirty water is the worlds largest health happen and it continues to threaten the quality of life and the public health in the linked States. The first problem is that people dont know how historic having clean water is until its no longer easily cordial for them. When people become more informed about the problems that we are facing and will face very soon as a society. We rout out take certain steps to fork up to prevent it and to ensure our quality of life not only stays the same, but improves.Little fuck be accomplished by one, but if we work together and try toconserve and keep our water clean, it can last much longer. The accusative of this experiment is relatively simple, to educate on how much we affect our surround 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 have trusty quality. It also has the purpose to let people know that their actions dont just affect them or only the people that they live al well-nigh it also affects the environment and the animals that inhabit it. During the experiment of the Water Quality and befoulment my conjecture were The Oil hypothesis was that if there is oil in the aerofoil water then, I think when the water is passed through soil it will be able to filter out the oil before it reaches the groundwater. The hypothesis for the vinegar hypothesis was if there is vinegar in the surface water then, I think that when passed through soil it will still roost in the groundwater.My laundry detergent hypothesis was if there is laundry detergent in the surface water then, when it is passed through soil it will still have traces of laundry detergent in the groundwater. The next experiments hypothesis was that using particular chemicals and methods of filtration, we should be able to remove most of the contaminates that are in the groundwater. This was the experiment that involved different methods of Water Treatment. The nett experiment pertained to the drinking water quality and my hypothesis was that tap water will contain the most contaminates because of its path and unknown condition. The bottles of water are in a more sterile environment. The Dasani water is treated 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 used soil, different beakers, wooden stir sticks, vegetable oil, vinegar, liquid laundry detergent, water, cheesecloth and moves. I poured water into each of the first 4 beakers, and then put vegetable oil, vinegar and laundry detergent in respectively. I stirred them with the wooden stir sticks and used the cheesecloth to line the funnel and put soil in and poured each of the different contaminates through, replacing the soil and cheesecloth each time. The second experiment involved beakers, soil, cylinders, sand, charcoal, stick to, wooden stir stick, alum, funnel, cheesecloth , bleach, stop watch and water. I addedsoil to a beaker and put water with the soil and complicated them with two beakers 15 times. I divvied some on the contaminated source into a new beaker and added alum to it. I stirred the mixture with a wooden stick for 1-2 minutes and then let it sit for 15 minutes. I lined a funnel with cheesecloth and layered sand, charcoal and gravel into the cheesecloth.I poured the clean tap water through the filter and ingeminate 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 few drops of bleach and stirred the combination for 1 minute. I then compared and annotated the now filtered water to the initial contaminated water. The final research lab contained Dasani bottled water, Fiji bottled water, Ammonia render slip-upes, Chloride psychometric prove peels, 4 in 1 test miscue, phosphate test strips, iron test strips, beakers, m arker, stopwatch, Parafilm, pipettes, foil piece of grounds of reducing grind 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 reading. 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 moody the excess 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 and wiggled back and forth.I briskly outside the excess 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 and held horizontal for 45 seconds, leaving th e 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 foil 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 mop up and tested and compared 10 seconds later.
