Beauty and Grace
So beautiful is spring, as a photograph taken,
a keepsake to treasure, and never retaken.
The cold winter days, and long winter nights,
have suddenly vanished, but no need for fright.
spring has arrived, with wonderful cheer,
the trees are now green, for once in the year.
The brisk autumn days, and leaves on the ground,
all raked away in a pile or mound.
All of the pumpkins have fled from their patch,
but spring has brought fruits grown by the batch.
The weather is calm, neither hot or cold,
the summer heats await, and springtime will hold.
So beautiful is spring, the air is fresh,
the dream of fair nature, is now in the flesh.
And why do I weep when spring rolls around,
the plants are so lively, as the grass on the ground.
This green spread widely, nothing left bare,
the sights are so precious, nothing can compare.
The hustle and bustle has come to a halt,
people will turn to watch the exalt.
But why does spring receive such high praise?,
The mild nights of comfort, and long sun filled days.
Kites of Spring
I came across your soaring kites flying so high
kissing the clouds of spring’s full and light blue sky,
And suddenly the ties snapped and broke away,
leaving you just to sulk, and nothing left to say.
It made you cry for goodbye you had to bid,
but then again I saw things different than ever you did.Though I heard your shrill voice through the trees,
I could not see your head bowed low, which brought me to my knees.
The wind that once gave you joy now leaves you to ball,
it felt your agonizing pain, and always heard you call,
You give and give, but in the end it only makes you ache,
for the wind has become the enemy, and only lives to take.

Water from both public and private supplies often needs some treatment to ensure that the water is sage and appealing to drink. Treatments for water can include simple filters in households to a complex process and a public plant.
Water quality: The measure of the substances in water besides water molecules.
PH: Ph is the measure of hydrogen in water which can determine the acidic or basic qualities of water is. Ph has a scale of 0 to 14. Pure water has a neutral ph level, meaning it is neither an acid nor base, and has a ph of 7. The lower the pH, the more acidic, and the higher the pH the more basic.
The level of calcium and magnesium in water is referred to as hardness; which contains high levels of these minerals.
Organisms that cause disease can be present in water as well. Measures of coliform can show the number of Escherichia coli bacteria, which is waste material.
A concentration of water is the amount of one substance in a certain volume of another substance.
Water Quality Standards
Substance Limit
Arsenic .05 parts per million (ppm)
Carbon tetrachloride .005 ppm
Copper 1.3 ppm
Cyanide .2 ppm
Lead .015 ppm
Coliform count > 5 % of samples taken in 1 month can be positive.
pH 6.5-8.5
TYPICAL WATER TREATMENT
Step #1
Filtration is the process of passing water through a series of screens that allow the water through, but not larger solid particles.
Step #2
Flocs are sticky globs that are formed from alum and other chemicals.
Coagulation is the process of other particles sticking to the flocs formed by the chemicals.
Step #3
Chlorine is added to water to kill disease-causing microorganisms. Sometimes other chemicals are added to water to kill specific organisms, such as Cryptosporidium.
Once water has been treated it is distributed to homes and businesses. From the treatment plant, the water goes to the central pumping station and then it is pumped through underground mains. From there they are branched into smaller pipes and into houses. Some communities store water in the air instead of underground. No in clouds or water vapor, but large tanks at the top of hills. Treated water is pumped into the water tower and is released into mains and pipers. Wastewater used in the home or other outlets are referred to as sewage. Many communities treat their wastewater to make it drinkable again. During primary treatment, solids called sludge are settled of the water.
Septic Tanks are underground tanks containing bacteria that treat wastewater as it passes through. The area that water filters into that is around the septic tank is the leech field.
Water shortages are when there is too little water or too great in demand or there is too little water, or both.
Chapter III Section II
The Colorado River provides water for many people in the desert Southwest, but once it flows through Mexico and up into the United States, it has been taped and little precipitation provides a lack of water. A water shortage occurs when there is too little water or too great demand in the area, or both. When a place of normal precipitation receives little or no water through a period of several years, it is known as a drought. A drought will affect groundwater and underground water supplies as well. Without enough water to get to the aquifer, its amount of water decreases. Many people overuse the aquifer, even when there is no drought. When too much water is pumped into it, the probability of it sinking of collapsing increases. Solutions of refilling the aquifer include injecting water underground, but since this is expensive and requires more water, it is easier to just not overuse the aquifer. Using a resource wisely so that it will not be used up is called conservation. Water is used mainly in the United Sates for home use, agriculture, and industry. For example, paper mills conserved water and use only half of the water used in the past to make the same amount of paper. Reducing water use, recycling water, and reusing water are three major forms of water conservation by industries. The process of obtaining fresh water from salt water is called desalination. A farfetched way of obtaining fresh water is also to pull icebergs by tugboat and melt them until liquid forms of water are present in large quantities.
Chapter III Section III
Contamination of fresh water became so bad in the Cuyahoga River near Lake Erie, that chemicals on top began to become flammable. The addition of any substance that has a negative effect on water or the living thinks that depend on the water is called water pollution. Some types of pollutants can build up in the bodies of living things such as the pesticide DDT which can be absorbed into water. The major sources of water pollution are human wastes, industrial wastes, agricultural chemicals, and runoff from roads. A specific source of pollution that can be identified is the point source and the less obvious source is the more dominant cause of pollution. A widely spread source of pollution that can’t be tied to a specific point of origin is called a nonpoint source.
History
Dr. John Snow discovered the reason of large amounts of illnesses in London was caused by Cholera in 1854. Many large cities have sewage lines which contain hazardous wastes. This sewage can seep into the water supply and pollute it. The result of rain with that is largely acidic is known as acid rain. Acid rain can eat away at stones of buildings and statues. Rich supplies of nutrients from fertilizers encourages the growth of plants and algae in and around nearby bodies of water. Pesticides are chemicals intended to kill insects and other organisms that damage crops. They may be sprayed onto crops but run off into large water bodies. The run off substances from crops and roads can run off into wells or even an entire aquifer. Living things in lakes, streams, and wetlands filter out and break down waste materials. Not only living things can help clean up polluted water. Passing through sand and rock can naturally purify water. Many recycling techniques can help conserve water and lessen pollution. Avoiding over fertilizing gardens and disposing of toxic substances can help homes lessen pollution.

Kinetic Energy is the form of energy that an object has when it is in motion.
Potential Energy is energy that is stored and waiting to be used.
Electricity produced by kinetic energy of water moving over a waterfall or dam is hydroelectric energy.
Hydroelectric power plants capture the kinetic energy of moving water and changing it into electrical energy.
Hydroelectric power is clean, safe, and efficient.
Although building a dam is expensive, the water is free and is naturally renewed by the water cycle.
Hydroelectric plats do have limitations.
Only certain locations are suitable for building a dam. A fast flowing river is necessary, and an area that can be flooded to create a reservoir.
For countries that want to strengthen industry, hydroelectric power is the best way to provide large amounts of power because it is cheap and widespread.
Dams that are large can provide much power, but effect the land around them.
