The process of purifying salty water to make it usable fresh water is extremely complicated and expensive and as such, people, many animals, and plants have to survive on the 1%.
There are three sources of fresh water used by people and animals; ground water, surface water, and aquifers. Surface water includes water that collects on the ground through the process of precipitation and which does not evaporate back to the atmosphere or even infiltrates to the ground. This water collects in such places such as rivers, lakes, among others. Ground water on the other hand settles underneath the ground, and is stored in pores, fractures, or solid rock underneath the earth surface. This water collects in these places through the infiltration process. Aquifers on the other hand are areas where water collects such as in sand, gravel or permeable rock.
Although rainwater is pure, it gets contaminated very fast, especially after it touches the ground through man made, natural and animal pollutants. Ground pollutants travel from one place to another through streams, rivers, or ground water while others are available in the air. Man-made pollutants include motor oil, petrol and diesel, acidic chemicals, among others.
There are many dangers of consuming contaminated water, especially the potential of these impurities in causing diseases. Poisons, disease causing agents and toxins can reside in water, and adversely affect people. Medics believe that contaminated water such as toxins and lead acid chemicals are responsible for majority of cancers affecting many people today. It is because of these impurities and dangers associated with contaminated water that water purification becomes ...Download file to see next pagesRead More

THEORY The water/cement ratio is one of the important parameters which decides the strength of the concrete (Newman, 2003). It can be assumed that generally the strength of concrete increases with the content of cement and decreases with air and moisture content. Given below is the graph which shows the relationship between water/cement ratio... at failure...

Water Quality and Contamination

... the same levels of chlorine with tap water. Fiji® Bottled water had more chlorine explaining its high pH. Discussion. The results from experiment 2 were able to support the hypothesis formulated for this test because the contaminants were able to completely contaminate the water as stated. On a large scale, these particular contaminants would have a harmful effect on the quality of a town’s water supply. Soil and detergents would make the water unpalatable because the water would have an unpleasant appearance and taste because of the detergent and the soil particles. This would necessitate the water to be treated for it to be suitable for human consumption (Howden & Marther, 2012). There are various sources of water contaminants... ?...

Water Contamination

...Water Contamination June 19 2009 Water pollution Water pollution is used to describe a body that is inadvertently affected by materials that make the content of the water unfit for use (Krantz & Kefferstein). In 1980, Anton Pohlmann arrived in Licking County, Ohio and bought 2,200 acres of farmland to start an egg producing facility (Egg cruelty). In 1983, Buckeye farm led to a massive manure spill in Otter Fork Creek Hills (Ohio History Central). This spill was responsible for killing 150,000 fish as the farm underwent expansion to fit in the production of more eggs. 1999 proved that Buckeye Farm had not done anything to reduce its manure content....

...of the water samples fall within the ranges set for clean water. Therefore my sample has good quality and is safe for drinking. 4. What results lead you to the conclusion in #3? Almost all the analysis results of my sample fall within the normal ranges for potable water. Low level soft nitrate-nitrogen show that the tap water source is not contaminated with pesticides and herbicides. 5. What may account for your results? All the practices followed to get clean and healthy water account for the results of the water analysis. In many countries, strong measures are used...

Water quality method for chemistry lab

...Water quality method for chemistry lab Introduction Determining the quality of water from various sources depicts whether the water from a specific source is suitable for human consumption or can support the life of aquatic plants plus animals. The experiment involves the collection of samples from the pond, and determining quantities of various parameters such as dissolved oxygen, nitrate levels, odor, turbidity, PH plus temperature. The results of these parameters depict the condition of water (Sturman & Kuruvilla 75). It is possible to perform a comparison of the results with the specific parameters in order to conclude whether the water sample meets desired qualities. Collection and testing of water quality is possible via... was...
