Water Discrimination Final Lab Report

My report was based on the how ground water may be affected by myriad containments present in our experiment and in our everyday . Surprisingly when vinegar was filtered through dirt it came out fairly clean. This surprised me because I would never believed that vinegar had such a profound effect on water considering its oily nature. I was convinced that vinegar more than the other contaminates would have produced a wider, more polluted field. I believed that all the water would have been contaminated with the dirt had been mixed in. This exercise may

Prepare the vessel for running the experiment. A fish tank will be used to simulate the natural environment, such as a lake, where these reactions would occur. The vessel needs to be duly and appropriately cleaned, and rinsed with distilled water to make sure that there are no contaminants within it.

The cup with the second greatest change in mass of the rock was number 2. Cup 2 had the solution of 10% vinegar and resulted in the change of -0.3g. Lastly, Cup 3 with distilled water had the lowest change in the mass of the rock, of 0g. It was hypothesized at the beginning that Cup 3 with distilled water would have the least amount of change, if any. This hypothesis was correct. Water is not acidic, so there would be no reason for the rock to change. When the hypothesis was conducted, it was based on the pH level. Instead, the actual solution should have been taken into consideration. The fact that the soda water would eventually lose its carbonation and become flat within a few days. Therefore, taking the acidity away. The experiment was done correctly, and there did not need to be any changes. Just the hypothesis could have been more thoroughly

Next, one of the 5 mL syringes was used to collect 1.5 mL of tap water. Before filling, the cap was removed from all the syringes. The water was checked for air bubbles. Throughout the experiment, if the fluid in the syringe had air bubbles it was emptied and filled until air bubbles were no longer present. The 1.5 mL of tap water was emptied into well #2. The same syringe was then filled with 2.0 mL of tap water. This water was then placed in well #3. Well #1 was left without H2O. The syringe was finally placed in the H2O beaker in order to keep the syringes

Beakers 5-8 were set aside for later use. I then recorded by observation of beaker 1 in Table 1 on the Lab Reporting Form; this included smell, color, etc. 10 mL of vegetable oil was added to beaker 2, 10 mL of vinegar to beaker 3, and 10 mL of liquid laundry detergent to beaker 4. Each beaker was mixed thoroughly with a wooden stir stick. My observations such as color and smell were annotated in Table 1 on the Lab Reporting Form. Next, I cut the cheesecloth into five different pieces. I took one piece of cheesecloth and folded it so it was 4 layers thick. I then placed it into the funnel. 60 mL of soil was measured out using the 100 mL beaker and placed into the cheesecloth lined funnel. The funnel was then put inside beaker 5. The contents of beaker 1 (water) were poured through the funnel and let filter for 1 minute into beaker 5. My observations were recorded on Table 1 on the Lab Reporting Form. I repeated the process of creating a filter of cheesecloth and soil and filtered the contents of beaker 2 (vegetable oil) into beaker 6, beaker 3 (vinegar) to beaker 7, and beaker 4 (detergent) to beaker 8. All observations were recorded on Table 1.

The purpose of this lab is to simulate the effects of slightly acidic rainwater on rocks and minerals.

The purpose of the experiment was to test the levels of water contamination in each beaker to see how high each vial would contaminate the water based on the color the water became once each vial was poured into the given beakers. In Experiment 2: Water Treatment, I used potting soil, sand, activated charcoal, gravel, alum, bleach, and beakers with my own-supplied tap water. The purpose of this experiment was to see if the different particles placed in the tap water could be removed by various filtration techniques. In Experiment 3: Drinking Water Quality, I used several various test strips, each individual strip testing for ammonia, chloride, 4-in-1, phosphate, and iron, along with samples of Disanti bottled water, Fiji bottled water, and my own tap water from home. The purpose of this experiment was to determine if bottled water is any more or less filtrated than my own tap water at home.

The control in the experiment is distilled water, as it does not contain sucrose solution.

These cleanups are required by federal and state laws passed in the last two decades mostly in response to public concern that drinking contaminated ground water may cause cancer or other illnesses. The laws require that, in most instances, the contaminated ground water be restored to a condition that meets state and federal drinking water standards. Businesses and government agencies paying for the cleanups are calling for reconsideration of whether returning all contaminated ground water to drinking water standards is a realistic goal. At the same time, public interest groups are advocating maximum protection of the public's right to a safe water supply in places where there is

Pre-test 2: Water from the taller and narrower beaker is poured back into the standard beaker and the child is asked to determine if the beakers have the same amount of water.

The exponential growth of human population, caused an unprecedented problem for the global ecosystem. (Carolina EcoKits, 2012) The increase in pollution brought upon great fear and concern about what types of contaminants were in the foods and water supply for citizens. In 1977, the Clean Water Act was passed, the act ensured that any release of pollutants at toxic levels into any water source was forbidden. (Carolina EcoKits, 2012) It allowed for the Environmental Protection Agency (EPA) to set guidelines and standards for how pollutants were emptied in navigable waters. (Carolina EcoKits, 2012)

My hypothesis was supported because there were some contaminants that were visible and there were some that were not visible. One of the contaminants that was visible with sample c was copper which was orange. Copper is an orange/red metal and it can be found in small amounts (less than 1 parts per million) in natural, ground, and surface water. However, elevated amounts may occur if corrosive water completely gets dissolved with copper water. This will only happen if corrosive water stays unmoving with copper water for six or more hours which will likely make the water more unsafe for drinking. It will be more unsafe for drinking because it can give a bitter taste and can cause discoloration in the water. Copper is also a contaminant that

Oil was present on the water surface proving my oil hypothesis correct. Vinegar having the least amount of effect on the groundwater, and showing clear visibility, was also correct despite carrying a slight odor due to contamination. Laundry detergent had a slight soap odor with a cloudy look to the water, resulting in backing up my hypothesis. For my second experiment the treated water mixed with soil became clearer, thus being filtered and supporting my hypothesis. For my third experiment, after three water sources were tested for contaminants, Dasani water had the lowest amount of contaminants, while tap water had the highest levels of contamination, supporting my

Recoveries experiments would be conducted to confirm the validity of the methods. Findings from this study would allow us to propose an efficient extraction procedure for selected imidazolinone herbicides in fish samples.

Step 1 and 2 was repeated by using distilled water by replacing the test solution.
