1. INTRODUCTION The tradition of bottled water and mineral water is not very old. Even in western countries the practice of bottled drinking water started in 1950s. The trend of having mineral water gained grounds in the market. Now around 100 companies sell an estimated 424 million liters of bottled water valued at around Rs. 200 crores in the country annually. Since ancient time people have used water from mineral springs, especially hot springs, for bathing due to its supposed therapeutic value for rheumatism, arthritis, skin diseases, and various other ailments. This started the trend of using mineral water for drinking purpose to exploit the therapeutic value of the water. This trend started gaining momentum in mid 1970s and since…

More and more people are using bottled water because of its easy assecability, and its conveince. Unaware to most, the useage of bottled water has dire effects on the environment, and itself can provide several health risks. Although bottled water can serve as a great convience, the harm it causes to the environment outweights its convience immensly and contrary to popular belief, bottled water is often no healthier than tap water. Despite perceptions that bottled water is healthier than tap water, more times than not, it is not amd bottled water has much more lienant rules when it…

Waterbottle

The consumption of bottled water has been increasing consistently over the last few years. Some reasons why people decide for an option that is often more expensive and less comfortable than tap water, could be their dissatisfaction with tap water taste and health-risk concerns. Other factors could involve, demographic variables and the perceived quality of the water source. Trust in tap water companies also seems to influence public opinion. The demand for bottled water has consistently increased in the past decade. The trend has been observed worldwide, but the rates of increase vary accordingly to the country. It has been said; bottled water has become the fastest growing segment of non-alcoholic beverages. Globally almost every country is accepting the bottled…

Kapshi Model Village

About this document: It is about a remote village named Kapshi in Maharashtra. A group of us from IIT Bombay visited the village to learn about the progress that was achieved there. This document is hosted on my website: http://www.it.iitb.ac.in/~gumma I can be reached at [email protected] Backdrop: Until about three years back, the village was experiencing severe drought conditions with no water availability during the dry periods. It was inspirational to witness the way villagers transformed their conditions with self-belief and a camaraderie that is worth emulating. 1 Efforts towards water conservation Kapshi experiences about 250-300 mm of rainfall every year, which occur in bursts of six to ten spells of rains from June to September. The water table of…

Lab Experiment Stoichiometry of a Precipitation Reaction

The purpose of this experiment is to use stoichiometry to predict how much of a product will be made in a precipitation reaction, to measure the reactants and products of the reaction correctly, to figure out the actual yield vs. the theoretical yield and to calculate the percent yield. Procedure First, 1.0 g of CaCl2·2H2O was put into a 100-mL beaker and 25 mL of distilled water was added. The two ingredients were stirred to create a calcium chloride solution. Then, stoichiometry was used to determine how much Na2CO3 was needed for a full reaction: First, 1 g of CaCl22H2O was converted to moles: 0.00680 moles. The mole ratios of CaCl22H2O and Na2CO3 was seen to be 1:1. Then, moles…

Seaworld Water Conservation in Sanantoino

Many of us have been to water parks/ theme parks and probably never thought about how much water is being used. I especially have been intrigued with the fact that San Antonio has a Seaworld, because the other cities that have one are San Diego and Orlando. San Diego and Orlando both are by many beaches and land of water compared to San Antonio. So to me I felt that San Antonio having a Seaworld would have a major impact on our city water supply. How much water does Seaworld consume and or try to conserve? I talked to Melissa, an educator at Seaworld, and she discussed with me that several of Seaworld’s management had already developed the park’s Water…

Qualitative Analysis Lab

The purpose of the experiment is to identify every cation present in an unknown solution by performing specific chemical tests. Chemical tests such as adding specific chemicals to make precipitates, adding strong and highly concentrated acids and bases, centrifuging the precipitate from the supernate, and performing a flame test are carried out to determine the presence or absence of the ions in each group. Experimental Procedure: Separation of Group I Cations: Ten drops of the unknown solution C were placed into a small test tube. Four drops of 6 M HCl were added to the unknown solution. After being stirred, the yellowish unknown developed a white, cloudy precipitate. The solution was centrifuged and a white precipitate sunk to the bottom…

The Story of the Flood- the Epic of Gilgamesh

‘You know the city Shurrupak, it stands on the banks of Euphrates? That city grew old and the gods that were in it were old. There was Anu,-lord of the firmament, their father, and warrior Enlil their counsellor, Ninurta the helper, and Ennugi watcher over canals; and with them also was Ea. In those days the world teemed, the people multiplied, the world bellowed like a wild bull, and the great god was aroused by the clamour. Enlil heard the clamour and he said to the gods in council, “The uproar of mankind is intolerable and sleep is no longer possible by reason of the babel.” So the gods agreed to exterminate mankind. Enlil did this, but Ea because of…

The Purity and Purification of Solids Recrystallization Lab

In this experiment, impure adipic acid is purified though recrystallization. The impure adipic acid is dissolved in a solvent. After cooling it is ran through a vacuum filter to separate any moisture. The dry crystals are then weight for percent yield and the melting point range is taken to test the purity. There were two different trials ran in this experiment. The difference between the two was the addition of charcoal in the initial step to remove color impurities. For part A (without charcoal) the initial impure weight was 1.0256g. After the filtration, the final pure product weighted 0.6063g which is a 59.17% yield. The Melting point range for part A was 151.1°C – 154.9°C. For part B (With charcoal)…

The True Tragedy of Water

Sweat is dripping off my face from this hot summer day and as I reach for my cold tea (filled with as many ice cubes as I could fit in) from my lawn chair, I start to think about something very basic. Water. As I hear my sister splash into the inflatable pool that I had to fill up with by turning the garden hose and just leaving it in there, I start to realize that my relationship with water is an utter tragedy. A tragedy of the commons. The definition of the tragedy of the commons is: The use of a depletable resource by many individuals that is used for independent gain, instead of a long term public gain….

Thermal Pollution

It is one of the pollution that effects on living things and the environment badly. The definition of thermal pollution is the degradation of water quality by any process that changes ambient water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the change in temperature decreases oxygen supply, and affects ecosystem composition. Urban runoff–stormwater discharged to surface waters from roads and parking lots–can also be a source of elevated water temperatures. When a power plant first opens or shuts down for repair or other causes, fish and other organisms adapted to…

Water Conservation

INTRODUCTION: Water is essential for life on earth. Water is needed for growing food, keeping ourselves clean, generating power, controlling fire and most importantly to stay alive! This list is simply non-ending. This shows that water is an integral part of our daily life and we are heavily dependent on it. Water conservation: Refers to reducing the usage of water and recycling of waste water for different purposes such as cleaning, manufacturing, and agricultural irrigation. Fresh Water Availability: * Two thirds of the surface of the Earth covered with water, so you might be thinking why it is a problem. It is because most human uses require fresh water with about 97.5% of the water on the Earth, salt water…

Water Scarcity is a Real Threat

The next war ripping across continents may well be triggered by water scarcity. Already a third of the world is suffering from water shortages. Ironically, rainfall has been adequate. The water is there. But what has gone awry is its management. Water scarcity in Asia and Australia alone affects a fourth of the world’s population and is triggered by over-usage whereas in Africa, it is lack of adequate infrastructure that wreaks havoc. Water scarcity around the world has come about primarily due to quintessentially wasteful practices that have seeped into present-day agriculture which sadly mops up 80% of fresh water. Over the past 100 years, water usage has gone up by six times globally, and is threatening to double again…

Bottled Water and Tap Water

The quality of water that we drink is a significant determinant of our health. Guarantee of the safety of water is a base for the prevention of diseases. Several people prefer to drink bottled or commercial mineral water in the presumption that they are safer and have quality as compared to tap water. I believe that tap water is the best choice for a few different reasons. Bottled water is very popular and easily available at most stores. Consumers spend a large amount on purchasing bottled water. People prefer bottled water over tap water because they are saved in plastic containers, which are less weighty. After consume these bottles, people discard the bottle instantly, thus removing the need to carry…

Determination of Water Hardness

Introduction: In this lab a total of six titrations are to be performed. Three of them will be done using a known Ca2+ solution, (1.000 g CaCO3 /L solution) and three of them will be done using an unknown solution obtained from the stock room. The objective of this lab is to determine the hardness of water, using the data collected from each titration performed with the unknown sample. Since the hardness of water arises from the presence of metal ions, we can use disodium salt of EDTA and the indicator Eriochrome Black T to determine the concentration of M 2+ ( Mg 2+ or Ca 2+) metal ion impurities. Chemical principle or theory involved in this lab: To determine…

Fresh Water

1. Introduction Fresh water is an indispensable resource for human livelihood, agricultural irrigation and economic development (Brooks, 2007). However, due to the rapid population growth and the limited reserves, increasing regions have faced serious scarcity of fresh water (Williamson, 2010). Saudi Arabia is one of the driest countries in the world (CIA, 2011). According to World Bank (2011), the world average fresh water consumption is nearly 7000m³/year/person, while the water resource per capita in Saudi Arabia is less than 1200m³/year/person. In order to satisfy the demand for water, Saudi Arabia currently supplies fresh water via deep drilling of fossil groundwater (UNESCO, 2009). Nevertheless, society increasingly recognises that those water resources are non-renewable and are liable to be reduced by the…

Procedures in Making the Soap Out of Pineapple Peel

Last month, I and my group decided to pick “Pineapple skin extract as soap” as our I.P title yet we are unaware of the things that might come our way. We are planning to conduct an experiment tomorrow using the procedures that we guess will work.We have separate procedures for our ingredients: For our pineapple skin extract 1)Cut the pineapple skin into one-inch squares with a sharp knife. 2)Put the pineapple skins in a pot. Add water until the skins are barely covered. 3)Cover the pot with a lid and put it on the stove at medium-high heat. Allow the water to boil for 20 minutes. 4)Remove the pot from the stove. Strain the mixture through a strainer. Discard the…

Separation Techniques

A mixture is usually an impure substance and it is necessary to separate mixtures in order to obtain its pure components. The components of a mixture are not chemically combined. Therefore, they can be separated by physical methods; the components of a mixture will still contain their properties. Methods used to separate mixtures depend on the physical differences between the components of the mixture. The main separation techniques include: Filtration A method which is used to separate a suspension, a type of mixture produced when a solute does not dissolve in a solvent. The mixture is poured into a filter funnel containing filter paper. The paper possesses small pores which allow the solvent to pass through but does not allow…

Solid and Melting Point

(2pts) Indicate the correct waste container for the following compounds: a. hexane – non-halogenated organic b. 10% NaOH – aqueous c. methylene chloride (dichloromethane) – halogenated organic d. magnesium sulfate – solid e. sodium hypochlorite – halogenated organic 2. (1pt) Describe the proper way to separate ground glass joints if they become stuck. The proper way to separate ground glass joints is to hold the two pieces of glassware with paper towels so that your hands are touching as close to the joint as possible and pull with a firm grip. Try to loosen with a slight twisting motion. If that does not work try to tap with a wooden handle and try to pull apart. Lastly you can heat…

Water Consumption in Saudi Arabia

The Kingdom of Saudi Arabia requires water for sustainable social and economic development. Given that the Kingdom boasts approximately 53 hectares of arable land (Library of Congress, 2006), it is important that the agricultural and industrial sectors as well as the rural and metropolitan population are well provided for with a consistent water supply. However, Saudi Arabia lies in the tropical and subtropical desert region of Asia. Therefore, kingdom is arid, thus receives little rainfall and is not endowed with permanent fresh water sources besides the 1750 km coastline of the Red Sea and the 480 km of coastline on the Persian Gulf (Library of Congress, 2006). This research paper will look at the water resources of the Kingdom of…

Water Pollution

Clean water is extremely essential for a healthy living. It is life’s most important basic necessity while dirty water is one of the deadliest killers. UN has estimated that 10 people die every minute from contaminated water. The World Health Organization estimates that 80% of all sickness and disease in developing countries is due to unsafe water. As water pollution is one of the most widespread problems and it has deadly effects, I chose this topic. Water pollution is the contamination of water bodies (e.g. lakes, rivers, oceans and groundwater). Water pollution occurs when pollutants are discharged directly or indirectly into water bodies without adequate treatment to remove harmful compounds. The project includes the Global perspective, National perspective, possible scenarios…

Coagulation and Flocculation

1.0 Introduction In this lab, we are conducting two experiments on natural surface water. The first experiment is to conduct jar tests to estimate an optimum dosage of iron salt to remove suspended solids. The seconds experiment is to observe the rate of floc formation nad sedimentation. 2.0 Background Coagulation and Flocculation: Coagulation and flocculation are important part in water and wastewater treatment. Coagulation is the destabilization of particulate matter by physical or chemical processes. Flocculation is the formation of larger particles that will settle out of the solution. They are usually the first form of treatment of water and wastewater to remove suspended matter or color. Jar tests are used as a control test for plant operations. Aluminum or…

Complexometric Determination of Water Hardnesss

Introduction/Background: This lab was about determining water hardness. Water hardness is the amount of metal ions in the water. The most common found ion in the water is calcium ions and typically with a charge of +2. Water hardness plays a big significance in our daily life because to many metal ions in our drinking water can have adverse effects on our body. You can measure the water hardness by EDTA titrations. EDTA is a disodium salt that stands for ethylenediaminetetraacetic acid and it is a chelating agent. Chelation is the process of a ligand forms a complex with a metal ion. Eriochrome Black T is an indicator you add to the water sample that will turn the water pink…

Extreme Ice

In this documentary film, “Extreme Ice,” produced by PBS TV, 2009, James and scientists shows how glacier ice is melting. James Balog, a photographer, wanted to document and help scientists to understand mountain monumental changes. So he surveyed the ice and went to the places such as Alaska, Green land, etc. The project team which called “Extreme ice” discovered that there were very serious problems. The sun was the most reason of ice melting. But now, such as Industrial revolution and fossil fuels output green house gases alter the planet. For example, Columbia bay where is the fastest melting ice in the world, the ice is going to be collapsed faster than before. Scientists eventually discover about the mystery of…

Eye Injury Risk from Water Stream Impact

Ocular injuries caused by solid projectiles have been described in the literature (Duma, 2005; Kennedy, 2006; Kennedy, 2007). However, the impact of a high-velocity water stream on the globe has not been previously quantified. Such pressurized water jets can be found in children’s water toys, squirt guns, and interactive water fountains. As the velocity of these water streams increases, product capabilities, and therefore popularity, likewise increase. In addition to those on the market, water gun enthusiasts custom build powerful guns in order to maximize flow rate, often in excess of 55 ft/s. Interactive water fountains (also called wet decks, splash pads, spray pads, or spray parks) are found in public areas and water parks throughout the country. The attractions feature…

Is Bottled Water Worth It?

In somewhat recent discussions, one of the worlds favorite grab and go drink has come into question whether it’s safe enough to drink or not and that is, bottled water. A well-known convenient commodity to everybody, but some argue it is neither healthy for our environment, our pockets, or ourselves. The people from this perspective say bottled water deserves to be banned because the negatives indeed out weigh the positives. On a different side of the spectrum others use bottled water’s good marketability, convenience and it being a better alternative to soda and other sugary drink found in schools as excuses to keep bottled from being banned. Another interesting view expresses the fact that bottled water is silly in itself…

Three Gorgeous Dam

Introduction: A computer simulated model of how the finished dam is supposed to look like A computer simulated model of how the finished dam is supposed to look like The three Gorges dam is the world’s largest dam with a total length of half a mile and 600 feet high. The construction of this massive dam took over 21 years starting from planning till the finished construction. The dam was built to stop the floorings that occurred and to cut down the greenhouse emissions of Chinas energy production. With t total production of 100 terawatt per year the dam provides 3% of Chinas total energy consume. But this dam had also been a disaster to the environment and the society….

Water Pollution

More people die from dirty water and poor sanitation in Africa, than acts of violence , including war(“Why is Clean Water so important?”). Children are especially targeted for disease, because their immune system is smaller, and they are younger (“Why Water?” ). Africa has many poor countries, and many people are dying from diseases in water. Every day, people have to walk over five miles to get a bucket of water for the family they are in. Most of the time, the only water people can find is dirty. Dirty water causes children to develop diseases every year. In fact, over eighty percent of disease is caused by unclean water (“Drop in the Bucket”). Many organizations are desperately working to…

Comment and Compare the Boscastle and Pakistan Floods

During the 2010 monsoon season (July and August), Pakistan experienced the worst floods recorded in its history. Heavy rainfall caused flash floods in the north and north-western regions of the country. The subsequent run-off created a southward moving mass of water approximately the size of the United Kingdom. The flood waters travelled downstream through Punjab and Sindh until they reached the Arabian Sea. Many of the main tributaries feeding into the Indus River were also flooded, further inundating agricultural lands. In total, some 20 million people were displaced and 50,000 square km were submerged, while standing crops, infrastructure and land were damaged extensively. The extent of the destruction caused by the 2010 floods is hard to comprehend. The floods impacted…
