Put them in a smaller mounts of water and then passed them though soil. Introduction In the introduction, I will list the problems with our world’s water sources.

Water Issues in Texas. (2014). Http://systematic. NP. Org/Texas/tag/water-issues/ These sources go on to state problems that we are facing as a population with our water quality. Some of these problems are 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 world’s largest health risk and it continues to threaten the quality of life and the public health in the United States. The first problem is that people don’t know how important having clean water is until it’s no longer easily accessible for them.
When people become more informed about the problems that we are facing and will face very soon as a society. We can take certain steps to try to prevent it and to ensure our quality of life not only stays the same, but improves. Little can be accomplished by one, but if we work together and try to conserve and keep our water clean, it can last much longer. The objective 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 have good quality.
It also has the purpose to let people know that their actions don’t 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 Oil hypothesis was that if there is oil in the surface 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 remain 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 experiment’s 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 final 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 Disdain water is treated and Fiji comes from a natural spring. The treated water (Disdain) will have the least amount of contaminates. Materials and Methods The first experiment that was conducted used soil, different beakers, wooden stir sticks, vegetable oil, vinegar, liquid laundry detergent, water, cheesecloth and funnels. 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 ACH of the different contaminates through, replacing the soil and cheesecloth each time. The second experiment involved beakers, soil, cylinders, sand, charcoal, gravel, wooden 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 solution 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. Poured the clean AP water through the filter and repeated 4 times. Poured 3/4 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 lab contained Disdain bottled water, Fiji bottled water, Ammonia test stripes, Chloride test strips, 4 in 1 test strip, phosphate test strips, iron test strips, beakers, marker, stopwatch, Paraffin, pipettes, foil packets of reducing powder and tap water. I labeled each of the beakers and poured Disdain, Fiji and tap water in each of the three beakers. Gathered the ammonia test strips and placed in the water and moved them up and down vigorously for 30 seconds each, I held each pad level for 30 seconds to get 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 off the excess liquid and determined what color the test strip was. I then used the 4 in 1 test strip and dipped in each f the beakers again, one at a time, for 5 seconds and wiggled back and forth. Briskly removed the excess water and waited 20 seconds to read the results. 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 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 foil packet and covered with paraffin 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. Results Experiment 1: Effects of Groundwater Contamination Table 1: Water Observations (Smell, Color, Etc. Beaker Observations It smells like normal water and appears to be clear 2 The water has a thin film on top that is yellow, it smells like oil, and now the entire water has a yellow hue to it. 3 The water has a thin film on top that is clear, it smells like vinegar, and the water remained clear 4 The water has a thin clear film throughout it, it smells like soap and has a blue hue to it 5 The water now has a brown hue to it and doesn’t emit any smells 6 The water still smells of oil and has an oil film on top of it, it also has a brown hue to it 7 The water has a brown hue to it and still smells of vinegar and has a film of oil on top. The water has a brown hue to it and still smells like soap and has a film on top of it. Experiment 2: Water Treatment The conclusion to this experiment was that the water is clear and doesn’t exhibit many odors. This was done by the coagulants latching to the larger particles and as pulled out of the water. The bleach changed the alkalinity of the water thus further decontaminating it.
