Wate National Environmental Engineering Research Institute (NEERI), Nehru Marg Nagpur - 440020 (Mah.); India Abstract: Present communication deals with a study of Physico-chemical parameters such as pH, Temperature, Total Suspended Solids, Turbidity, Dissolved Oxygen, Biochemical Oxygen Demand, Nitrate, Phosphate and Fecal coliform in water samples of rivers, lake and canal in Gujarat state of India. The water quality of the samples was compared with standard values given by World Health Organization (WHO) and United State Salinity Laboratory for drinking and irrigation purposes. Water Quality Index (WQI) was also calculated to know the overall quality of water samples. The results show that the water quality index is observed in the range of 44-61 and expected in the range of 45-64 which shows marginally water quality for drinking purposes. The water quality index is calculated by indicator (100-point scale) shows that this water can be used for drinking purpose after purification treatment. Results show that quality for irrigation purpose is quite good. Key words: Water Quality Index, Rivers, Lake, Canal, Surface...

Hello,

Here is yet another essay of mine. The topic is

"Many parts of the world are losing important natural resources, such as forests,

animals, or clean water. Choose one resource that is disappearing and explain

why it needs to be saved."

If you take a look and propose any suggestions on its imporovement, I'll be very obliged.

Essay:

All organisms on Earth somehow depend on water. And if the water they consume is adulterated, it may result in fatal changes in consuming organisms' lives.

Water is of a great significance for people, since it is used for drinking and in food. The human organism must receive a certain amount of water every day. Otherwise, if an organism does not obtain the required amount of water for several days, it dies. It is obvious that the water consumed by the human organism should be pure. Water that contains any harmful bacteria or chemicals may cause various diseases of an organism or even death. Animal organisms depend on water in the same way. Organisms of some animals are more resistant to soiled water than human organisms. For instance, if a human drink from a puddle on a street, it is highly probable that one will get intoxicated, while a bird drank from the same puddle won't get any harm. However, if water contains some caustic chemicals of artificial or natural origins, it may significantly harm both humans and animals.

Water also serves as a major nutritive component for all plants. Water is used by a plant participating in a process of plant's development and growth. A plant obtains nutritive substances from the soil by absorbing water that contains these substances. Some deleterious chemicals being contained in water may blight a plant causing its growth stop or death.

Water serves as a habitat for various animals. These animals not only drink water, but they are in contact with water during all their lives. The more close is the contact with water, the more water influences on these organisms. Water interacts not only with these animals' digestive systems, but also with their external tissues, and the harmful chemicals the digestive system may successfully resist may injure tissues. Though, humans don't live in water, they spend some time in it, while taking a shower or swimming, so their tissues are also exposed to water.

It may be concluded, that all live organisms on Earth utterly depend on water, and if the water they consume is not clean, it reflects negatively on these organisms. Water refinery systems partially solve the problem for humans who are beyond such a barrier. However, people in non-developed countries do not necessarily have such refinery systems; they consume water directly from its natural sources, as do animals and plants. That is why it is highly important to make all natural water sources clean, so all live organisms on the planet have access to clean water.


Thanks in advance.
