ABSTRACT: Experiments were done on the water quality and the contamination of groundwater. First, I observed the effects that different pollutants had on groundwater. I predicted that the experiments with the oil and vinegar would create the most contaminations to the water. When the laundry detergent were mixed with the groundwater, it created a light green color with a pleasant smell. The second water treatment experiment were about filtering techniques to remove contaminants from water. I predicted to drain the water by removing all the contaminants

Then place the funnel on the top of the beaker and let it sit there for 5 minutes before emptying the beaker. Now without mixing up the contaminated water jar, pour 3/4 of the contaminated water into the funnel and let it filter through the funnel into the beaker for 5 minutes and notice the smell of the filtered water comparing it to the 10ml. sample taken from the mixture earlier. Next remove the filter and add a few drops of bleach into the filtered water in the beaker and stir slowly for 1 minute. Since now the contaminated water has been filtered, compare the treated water with the 10ml. sample of the contaminated water and record your observations. In experiment 3 drinking water quality, I will test the quality of two different types of bottled water and tap water using materials such as: Dansani bottled water, Fiji bottled water, ammonia test strips, chloride test strips, 4 in 1 test strips, phosphate test strips, iron test strips, (3) 250ml. beakers, parafilm, pipettes, (3) foil packets of reducing powder, stopwatch, permanent marker and water. First you must label the (3) 250ml. beakers with Tap water, Dasani, and Fiji, and pour 100ml of each type of water into the beakers name. Next place an ammonia test strip with the pads down into the tap water and move it up and down for 30 seconds. Next remove the test strip shaking off excess water and then hold level with pad side up for 30 seconds. Read the results of the strip pads by
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
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.
When recording my results I realized that my hypothesis was not acceptable the cheese cloth working as a filtration system removed most of the contaminants from the water with the vinegar added leaving very little change. In the other beakers it was as I expected, there was
The human body is contained mostly of water. Plants and animals will stop to exist without water. Water is used in transportation, cleaning, and other walks of life. It is not hard to figure out that water is one of the planet’s most valuable useful things (Bottcher 2012). However, the previously-mentioned walks of life create many of the concerns connected with the consumption of water. Water contamination is a hot topic in America. Americans are concerned with the contaminants that may be waiting in a creepy way their tap
My lab report was based on how ground water could be affected by contaminants that surround us everyday. “ Access to safe drinking water depends not only on the quality of water at source but also on contamination throughout it's way to the user and practices related to purification and sanitation” ( Mishra, S., & Nandeshwar, S. 2013).I was very surprised that the detergent contaminated the water. I thought that the detergent would stay in the soil but it ended up going through the soil into the water. Which then left the water bubbly and dark. These labs may show that we may need to look into more
I was fascinated by this experiment that we recently did on water contamination, tap water versus expensive bottled water. Our water is tap well water. While exploring the topic futher, our research area took place on our kitchen counter where we observed how the test chemicals reacted with the tap water versus the bottled waters. We needed to follow the directions thoroughly, so we got accurate results. We started with test strips of ammonia: all three glasses of water contained: 0 mg/L of ammonia, 0 mg/L of chloride. The 4 in 1 showed: Tap water; 0 mg/L, total alkalinity; 10.0 of total chlorine, 120 mg/L of total hardness. The Dasani revealed 40 mg/L of total alkalinity, 0 mg/L of total chlorine, 0 mg/L of total hardness. The Fiji
To develop a better understanding of water contamination, a field comparison between two separate water sources was conducted. The first water sample was gathered from the Simmons Park Pond and the second from a NES water fountain. The data gathered from this experiment was used to answer several questions regarding the prevalence of contamination in nearby water sources. The field analysis ultimately concluded what contaminants had the greatest prevalence, thereby exemplifying the defining differences between the two water sources.
The purpose of the succeeding article is to weigh the opinions of two different sources concerning the topic of water pollution. Many people neglect the water issue due to the fact that it does not necessarily pertain to them. However, there are several complications that should definitely be brought to awareness among the public. This article uses two sources to explain why and how the activities of humans contributes to the poisoning of the world’s water supply, and how the articles use argumentative such as ethos, logos, and pathos to justify and compare their position.
The experiment was started preparing 300 mL of a 2 M HCl solution. A graduated cylinder was used to collect 200 ml of deionized H2O, then it was added to an empty 600 mL beaker which was designated to be the 2 M HCl solution. 100 mL of 6M HCl was then added to a sanitized graduated cylinder and poured into the 600 mL beaker with H2O. The solution was then stirred with the glass rod. 150 mL of a 2 M NaOH solution was then prepared. 50 mL of deionized H2O was added to a 400 mL beaker. Then, a graduated cylinder of 100 mL 3 M NaOH was added to the beaker. Repeat stirring. LabQuest was then configured and setup for data collection of Part A; the interval box should be set to 15 seconds.
The contamination of water and drinking supplies with high concentrations of nutrients from animal waste has fatal effects on different organisms. “Elevated nitrates in drinking water...hinders the ability of the...blood to carry oxygen” (Hribar 4), which can cause serious health conditions such as birth defects, miscarriages, and can even lead to death in seniors and infants. Although nitrates may have the greatest consequences on younger and older individuals, adults that consume tainted water develop increased risks of “cancer and non-cancer diseases...diabetes...and neurodevelopmental defects” (Halden and Schwab 16). Contaminated drinking water poses a serious threat to human health, and can affect people’s happiness and quality of life.
There is greater awareness of the issues and hazards of the dumping of chemical waste and there are laws restricting the dumping of this waste. Since many individuals rely on groundwater for drinking water, many of them are drinking contaminated water. Due to this, there are many health risks including, hepatitis, poisoning and cancer when exposed to polluted water. As well, the wildlife can be harmed from the contaminated ground water.
Few people give much thought to what’s in the water that comes out of their faucets until a funny smell or color alerts them that more than just water is coming from the tap.
Step 1 and 2 was repeated by using distilled water by replacing the test solution.
Few resources are essential to human survival. Access to clean water is the most critical of all. Water is a vital resource responsible for sustaining all life on earth. However, clean water is in short supply, but in high demand in all parts of the world. It is thought that most Americans have access to safe, affordable, clean water right from their taps. However, the media is uncovering the true nature of America’s deteriorating water situation. Americans have reason to be seriously concerned about the state of their drinking water. So what really is on tap in America?
Water hardness is typically known as the amount of minerals present in an aqueous solution. It specifically looks at the amounts of dissolved calcium and magnesium in the water. Hard water generally has high levels of dissolved minerals whilst soft water has low levels.
