Dependence of Man on the Environment

...Water Quality and Contamination Lab Report Kathryn Thomas SCI207: Dependence of Man on the Environment Instructor Joseph Fiedor October 6, 2014 Water Quality and Contamination Lab Report Abstract The water filtration process was examined using oil, vinegar, and detergent to show how well the process works. The watercolor, consistency, and smell would change allowing the difference to be seen. Different kinds of water were tested using test chemical strips to evaluate the chemicals within them. The reason was to show that bottled water was not better for human consumption than tap water. Contaminants can be carried from one point to another and can affect human health. Water quality is very important and knowledge gained in our communities can make a difference. Introduction Water quality research is important because it helps to protect and restore the quality of the Nation’s water. Certain standards help to identify problems caused by incorrectly treating wastewater, sediment, fertilizers, and chemical from agricultural areas. Standards are put in place to achieve and preserve protective water quality conditions. (EPA, 2012). Water quality affects ecological processes such as good river health, vegetation, wetlands, and birdlife. Our water resources have major environmental, social, and economic values. If the water quality is not maintained, it will affect more than the environment; it will affect commercial and recreational values as well. (NSW, 2012). The main...

...Environmental Science Table of Contents Lab 2 Water Quality and Contamination 21 Water Quality and Contamination Concepts to Explore • Usable water • Ground water contaminates • Ground water • Water treatment • Surface water • Drinking water quality Figure 1: At any given moment, 97% of the planet’s water is in the oceans. Only a small fraction of the remaining freshwater is usable by humans, underscoring the importance of treating our water supplies with care. Introduction It is no secret that water is one of the most valuable resources on planet Earth. Every plant and animal requires water to survive, not only for drinking, but also for food production, shelter creation and many other necessities. Water has also played a major role in transforming the earth’s surface into the varied topography we see today. While more than 70% of our planet is covered in water, only a small percent of this water is usable freshwater. The other 99% of the water is composed primarily of salt water, with a small percentage being composed of 23 Water Quality and Contamination glaciers. Due to the high costs involved in transforming salt water into freshwater, the Earth’s population survives off the less than 1% of freshwater available. Humans obtain freshwater from either surface water or groundwater. Surface water is the water that collects on the ground as a result of precipitation. The water that does not evaporate back into the...

Lab Report

...Final Lab Report (Water Quality and Contamination) Student’s Name Course Name Institution Instructors Name Date of Submission Final Lab Report Abstract Establishing water quality was done by analyzing the chemical, physical and biological characteristics. This process helped determine safe water for human consumption in public in addition to making sure that humans are not affected by chemicals or disease causing organisms. This was done by analyzing 3 water samples which entailed Tap water, Fiji® bottled water and Dasani® bottled water. The goal of this research was to establish the effects of ground water contamination. This research necessitated hypothesizing on the capability of oil, vinegar and laundry detergent to pollute ground water in view of soil as a contributing filter of oil. Arising from the results obtained from the data analysis and observations from the experiments, conclusive evidence about bottled water was deduced and further research consideration is brought to light. Introduction Water quality was established by analyzing various characteristics which entail chemical, physical and biological. There are benchmarks of water quality set for every of these classes of characteristics. The benchmarks for water quality are advanced by (EPA) Environmental Protection Agency (2004) and (WHO) World Health Organization (2011). The quality of water taken in public was determined in the view of these benchmarks. Water quality research is significant due to...

...Final Lab Report James Dillon SCI 207: Dependence of Man on the Environment Instructor: Jessica Bostock February 20, 2016 Final Lab Report Abstract The experiments conducted for this lab report focused on water contamination and filtration. Experiment 1 was effects of groundwater contamination. Oil, vinegar, and laundry detergent were added to clean water with no means of filtration. The clean water was found to be contaminated. A filtration system consisting of cheesecloth and 60 ml of soil was created and the contaminated samples were filtered through it. The soil and cheese cloth did not affectively filter the contaminants. Experiment 2 focused on water treatment and a filtration system using cheesecloth, sand, activated charcoal, alum, and gravel was created. The contaminated water sample was created by mixing soil and water together. After the contaminated water was put through the filtration system and a few drops of bleach were added you could see that much of the sediment was filtered out, but an overwhelming bleach smell remained. The third experiment was to determine drinking water quality. Samples of Dasani and Fiji bottled water were compared to my local tap water. Test strips were used to determine each samples ammonia, chloride, alkalinity, chlorine, hardness, phosphate, and iron levels. The results were that the Dasani water was cleaner overall and that the Fiji water and...

...to attempt to clean the ground water and make it drinkable. We also tested various bottled and tap water for certain chemicals. Introduction Many areas have water containing impurities from natural or artificial sources. These impurities may cause health problems, damage equipment or plumbing, or make the water undesirable due to taste, odor, appearance, or staining. Those impurities which cause health problems should be attended to immediately; other problems caused by water impurities can be corrected if they are a nuisance. Before beginning any treatment plan, have water tested by an independent laboratory to determine the specific impurities and level of contamination. This will help you select the most effective and economical treatment method. (Ross, Parrott, Woods, 2009) The reason why we conducted this experiment is to test the filtration to remove oil, vinegar, and laundry detergent has on soil before it reaches groundwater. These chemicals go to our local water supply, but first it goes through the soil. Materials and Methods The materials and methods section should provide a brief description of the specialized materials used in your experiment and how they were used. This section needs to summarize the instructions with enough detail so that an outsider who does not have a copy of the lab instructions knows what you did. However, this does not mean writing every little step like “dip the pH test strip in the water, then shake the test strips,”...

...The Quality of Water: Tap and Bottled Water Tiffany R. Jones SCI 207: Dependence of Man on the Environment Instructor Leslia Wilson 3/2/2015 Introduction Body Paragraph #1 - Background: The debate of water quality and the effects it has on the public is one that has a lot of weight to it. The advancement of water testing has evolved into one that is of meaning, and is talked about frequently. Efficient testing of the water supply makes way for people to know what they are drinking. According to the Environmental Protection Agency (n.d.), “Climate change can have a variety of impacts on surface water, drinking water, and ground water quality.” In testing the water quality and contamination, the EPA regulates a lot of different ways to get the water clean to get it to become drinkable. According to the Centers for Disease Control (n.d.), “Even though our tap water supplies are considered to be one of the safest in the world, water contamination can still occur.” The occurrence of this is because of places not being regulated and inspected properly. Coming out of the Natural Resources Defense Council (n.d.), “Studies have shown that chemicals called phthalates, which are known to disrupt testosterone and other hormones, can leach into bottled water over time.” The plastic used in that of bottled water tends to have an effect on the human body, and can pose a threat. Body Paragraph # 2 - Objective: There is still a lot to be learned about the difference between tap...

...WATER QUALITY AND CONTAMINATION Name: Instructor: Institution: Course: Abstract The experiment was based on the identifying the effect of different contaminants on ground water. The yielded result indicated that, when vinegar is filtered through dirt the vinegar filtrate was relatively clean. The results noted were indicative that vinegar is not affected by contaminants that affect. Introduction In the lab report, we will have a look at how various contaminates influence the water supply. In the world, there are various contaminates that contaminate ground water. These contaminants range from the simple items we use in the house such as cooking oil and laundry detergents to the well-known contaminants that come from agricultural and industrial processes. The experiments sought to answer the question how and why these particular contaminants affect what we drink from the faucet. One of the most common contaminants in water is lead. Studies have indicated that had a detrimental effect on children especially those in the development stages of their life and cancer in adults. According to Bruce Lanphear, a renowned pediatric epidemiologist, lead found in water is usually underappreciated service in terms of intake of lead. Statistics has shown that approximately 10-20% of children are exposed to lead through intake of drinking water. Pharmaceutical chemicals are another common contaminant of water. Many individuals usually do not know that they are exposed to this form...
