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 add laundry detergent to water in the washing machine, or notice oil within a

puddle on the street. These chemicals run off into local water sources, but run through soil first. It is

important to know how effective the soil is at removing chemicals like oil, vinegar, and laundry

detergent.

...Week 5 – Water Quality and Contamination Final Lab Rona Harris SCI 207: Dependence of Man on the Environment Instructor: Jacqueline Poole 10/6/2013 Week 5 – Water Quality and Contamination Final Lab Abstract Testing of how ground water is affected by different contaminants was the bases of the experiment. The results were interesting in that when vinegar is filtered through dirt it came out fairly clean. This is surprising because I did not think that any of the contaminants used would affect the water the way it did with vinegar. I figured all the water would have dirt mixed in with the water that was filtered. This shows that maybe we can find a way to find a safer choice on how we filter and purify water. Introduction In this Lab we will explore how contaminants affect the water supply. Contaminants can be anything from human waste, chemicals used in farming and industrial factories to the laundry detergent and cooking oil that you use at home. We are going to asking how and why this affects us when we drink water from the faucet. One contaminant that is found in water is lead. Studies have shown that lead can led to developmental delays in kids and can cause cancer in adults. According to Bruce Lanphear a pediatric epidemiologist, “Lead in water is an underappreciated service of lead intake" (Renner, 2009. A544) It is estimated that 10-20% of children are exposed to lead through the drinking water according to the Centers for Disease Control and...

Water Quality and Contamination

...Lab 5 – Weather and Climate Change Lab 5 - Demonstration 1: Modeling the Water Cycle POST LAB QUESTIONS 1. Which water cycle processes are represented in this model and by what components? Answer = evaporation, and condensation. The warm water evaporated into water vapors, that it transformed back into a liquid state during the condensation process. 2. Which processes are not represented? How could the model be altered to include these processes? Answer = surface run off, infiltration, and percolation. Its components is how the water vapor turns to gas. 3. How would the “weather” be affected if the water was at a decreased temperature? What about at an increased temperature? Answer = if it is decreased temperature the weather will be cold or stay warm within a humidity climate. And if the temperature increase the weather will be hot because we know that the water is being evaporate at that time according to the water cycle process. Experiment 1: Water Movement POST LAB QUESTIONS 1. Develop a hypothesis predicting the effect of sunlight on evaporation? Hypothesis = direct sunlight will lead up to more evaporation. The direct photons of light increases the motion of the water molecules it strikes giving them a better a chance to evaporate. 2. Based on the results of your experiment, would you reject or accept the hypothesis that you produced in question...

Water and Contamination Final Paper

...Water Quality and Contamination SCI 207: Dependence of man on the environment Instructor: Marc Hnytka Date: September, 2014 Water Quality and Contamination Abstract The correlation between water quality and contamination was examined through using different substances in the water along how these substances effected the water quality. Different levels of contamination is seen through the process of different acids (vinegar) oils (cooking oil) and fragrances (laundry detergent) in three different water models. When these contaminants are filtered naturally through the earth (charcoal, gravel, sand, etc.) the outcome is a purified water from each containment sample. This overall theory suggest that natural filtration will take place if the eco-system is not overwhelmed by these contaminants. Introduction Water quality is important when providing sufficient ecological balance for drinking purposes, vegetation and more particularly fish species. The most important resource used in America, such as growing crop, is produced consistently through the provision of monitoring the quantity of water sources along with the quality of what the water contains. There are certain minerals and contaminates that can harm us as humans and also the eco-system. For example, oil spillage from drilling, nuclear plants, and use of GMO’s to grow food can have a major impact on the water quality and soil. An article states that “When water from rain and melting snow runs off roofs......

Water Quality and Contamination

...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......

Water Quality Management

...Water Quality Management Water Pollutants and their Sources Water pollutants are categorized as: Point Source – pollutants that enter watercourses through pipes or channels. These can be discharges from sewage treatment plant or factories. Nonpoint Source – pollutants that originate from multiple sources. Several points of contamination over a large area contribute to the pollution of a water body. E.g agricultural runoff and construction sites. Types of Pollutants: 1. Oxygen-demanding substances/wastes - biodegradable organic compounds contained in domestic sewage or certain industrial effluents. When these compounds are decomposed by bacteria, oxygen is removed from the water. If the oxygen level drops low enough, the fish will die. Examples: * Sewage – includes domestic and hospital wastes, animal and human excreta etc. * Animal Manure and Plant residues - These substances in water causes increased algal blooms and microorganism population. This is introduced into water due to sewage, agricultural run-off, paper mills, food processing etc. 2. Sediments - particles of soils, sands, and minerals washed from the land. They can smother bottom life such as shellfish and coral, as well as fill in reservoirs and harbors. * Organic sediments - can deplete the water of oxygen, creating anaerobic (without oxygen) conditions, and may create unsightly conditions and cause unpleasant odors. 3. Nutrients - such as the nitrogen......

Water Quality

...of the household emissions calculator, name at least 2 actions that you can take to limit your carbon emissions? Include in your answer the exact dollar savings and the weight of carbon dioxide that could be saved (from the calculator results) for each of these two actions. Answer = One action I can take is to reduce my carbon emission is to keep my heating thermostat on winter nights down by $72 which will save me $644, Also I would replace all my 11 incandescent light bulbs with Energy Star Lights which will save me $44 4. Does reducing the size of your ecological footprint necessarily mean reducing your quality of life? Why or why not? Are there ways of enhancing your quality of life while lowering your environmental impact? Answer =No, I do not believe reducing the size of my ecological footprint would mean that my quality of life would get no better. Changing certain things like my light bulbs or keeping my thermostat down to 72 is very inexpensive and yes it will help me to save on those things but lowering and changing some of my habits will help lower the impact on the environment around us.

... Final Lab Report Water Quality and Contamination Rachel Hewitt SCI207: Dependence of Man on the Environment Professor Andrea Van Gunst May 16, 2016 ABSTRACT All lab experiments were conducted in Windham, New York. The first experiment regarding water quality and contamination, used vinegar, liquid detergent and vegetable oil to contaminate tap water. The results of this experiment showed that when the water was contaminated and filtered through dirt some of the contaminates remained trapped in the soil and didn’t contaminate the groundwater but some did. This experiment could help in finding safer ways to purify and filter water. The results of this experiment were that the oil separated in the water and was trapped in the soil not the groundwater. The vinegar changed the smell of the water and contaminated the soil but without any major effect on the groundwater. The liquid detergent also changed the smell of the water as well as the color but also contaminated the soil and groundwater. The next experiment that was conducted was to use products like sand, charcoal and gravel to filter contaminated water that had been treated with alum. The products were used as an aquifer. The results of this experiment were basically if you used coagulants combined with alkalinity you would be able to remove contaminants from the groundwater. The last experiment bottle water and tap water were compared and tested for levels of iron,......

Water Quality in Rural Areas

...consume water that is of low quality, with the chief reason for such low standards in water quality being contamination by pollutants that originate from various sources. Rural areas in most underdeveloped and developing countries do not have piped water and they rely mostly on wells or boreholes, rivers, springs, and rain water for their domestic consumption. Human activities such as intensive farming that use a lot of pesticides, fertilizers, and herbicides, mining, and industrial run off are the primary sources of water pollutants and contaminants. According to Li L, Li CS, and Wichelns’ (2016) study established that rural areas in Tra Vinh Province of Vietnam experience seasonal fluctuations of water quality annually. L, Li CS, and Wichelns (2016) observed that during the wet monsoon season in the Mekong Delta, the inhabitants have access to abundant rainwater that they collect for both domestic and commercial applications. However, during the dry season they are faced with acute shortages of clean and safe drinking water often opting for canal or groundwater that is usually contaminated and unsafe for human consumption. L, Li CS, and Wichelns (2016) observed that during the wet season, inhabitants of the Mekong Delta were unwilling to purchase clean and safe bottled drinking water from vendors compared to the dry season when demand for the same was extremely high. A study carried out by Trevett, Carter, and Tyrrel (2004) in rural Honduras to investigate water quality......
