...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...

...WATER QUALITY AND CONTAMINATIONS PG. 1 Water Quality and Contamination Nalissa Johnson SCI207: Dependence of Man on the Environment Otishna Jacobs 16 August 2015 WATER QUALITY AND CONTAMINATIONS PG. 2 Introduction Ground water is the biggest source of drinking water available to human population around the world and is rapidly being polluted because of industrialization and increasing demands of agriculture around the world. “Ground waters frequently contain iron, manganese and ammonium above the allowed concentration levels for drinking water”(Strembal, 2004)There are a lot of dangers associated with drinking or cooking with contaminated water. Diseases, poisons, and toxins can be found in contaminated water. There is also a possible correlation between an increased cancer risk and consuming contaminated water. “Being out of sight, it is not always apparent that damage has been, or is being, done to the groundwater resources. The need to prevent groundwater pollution is important because of the very high proportion of groundwater resources that are used for potable supply.” (Helmer, 1997) The objective of the first experiment we conducted was to test the ability of soil to remove oil, vinegar, and laundry detergent from the environment before it reaches ground water. We want to know this because often we...

...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...

...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...

...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...

...Abstract In this lab we tested the contamination of water using oil, vinegar, and soap. Using plain tap water I added various amounts of contaminants to the water and noted the change. Introduction The introduction should describe the background of water quality and related issues using cited examples. You should include scholarly sources in this section to help explain why water quality research is important to society. When writing this section, make sure to cite all resources in APA format. The introduction should also contain the objective for your study. This objective is the reason why the experiment is being done. Your final report should provide an objective that describes why we want to know the answer to the questions we are asking. Finally, the introduction should end with your hypotheses. This section should include a hypothesis for each one of the three experiments. These hypotheses should be the same ones posed before you began your experiments. You may reword them following feedback from your instructor to illustrate a proper hypothesis, however, you should not adjust them to reflect the “right” answer. You do not lose points for an inaccurate hypothesis; scientists often revise their hypotheses based on scientific evidence following an experiment. 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...

...Clean Water Project Report Day 1- “The Balanced Equation” Documentary Notes In the documentary, “The Balanced Equation”, a group of high school girls tells their story of traveling to Kenya and the Dominican Republic to investigate and learn more about issues dealing with water in developing countries. The girls focus primarily on problems with water that exist in these countries and the water filtration systems being provided. According to the video, approximately 3.5 million people die from water-related illnesses each year, and over 800 million people do not have access to clean water today. The girls discover that portable point-of-use filtration devices are given to those in developing countries who don’t have access to clean water. Permanent water solutions, such as digging wells, have been tried, but often fail due to lack of maintenance and education. Wells often become contaminated with runoff water among other issues, so over 50% of these permanent solutions fail after 5 years. Instead, point-of-use water systems are distributed since they are portable and can be used at home. The girl’s spent their first night of their adventure in...

...of our planet is covered in water, only a small percent of this water is usable freshwater. (eScience Lab 2, 2012) Most of our freshwater is frozen in glaciers at the poles, which means that it is not a viable option because melting them would disrupt the delicate balance of that ecosystem. The small percentage of fresh water that is accessible is stored underground in aquifers. These aquifers collect precipitation like rain water and water from melted snowfalls and stores it in ducts and pores, layers beneath the earth’s surface. When you think about the fact that there are over seven billion human being on this earth and countless other species that depend on freshwater to live and how little there actually is that alone is legitimate cause for alarm. In addition a lot of our technological advances, which have enabled us to feed a growing population by using chemicals to grow more crops, can threatened and potentially contaminate our freshwater supply. A good example of this as explained by Turk & Bensel 2011, is the fact that nitrogen and phosphorus are important crop nutrients, and farmers apply large amounts to cropland each year. They can enter water resources through runoff and leaching and affect water quality through eutrophication, which can result in decreased oxygen levels, fish kills, clogged pipelines, and reduced recreational opportunities. Another reason why water quality research is so important is because growing urban water demands have long clashed with...

...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,”...

...Introduction Lab safety is the most crucial part when working in a laboratory. Following all the proper precautions and acknowledging the lab protocols will ensure that everyone in the laboratory does not get harmed in any way. The three modules reviewed in this lab included: personal safety protocols, proper hand washing techniques, and proper disposal practices. Reviewing and practicing all three of these modules helped me recall and understand the importance of lab safety. Methods and Materials The first portion of the lab was over proper hand washing techniques. Proper hand washing includes using water, soap, a nailbrush, and paper towels. First you remove all jewelry from your hands and wrist. Next, you turn on the water and then apply soap to your hands. You must rub your hands together and scrub for at least 20 seconds. During this process of scrubbing your hands, you will use the nailbrush to clean under your...
