Although water constitutes 71% of the earth’s surface, yet only 0.3% of it is available as fresh water for human use. Moreover, it is the quality of such freshwater in ground and surface system that is of utmost concern to us as potable water needs to be appropriate in terms of calories and organic nutrient content. Ground and surface water quality either in rural or urban environment is affected both by natural processes as well as anthropogenic influences. Because of this, the water is becoming scarce day by day as the population increases across the world. Changes in water quality due to natural processes are because of weathering of rocks; evapotranspiration; depositions due to wind; leaching from soil’ runoff due to hydrological factors; and biological processes happening in the aquatic environment. The changes that occur due to natural processes bring about change in PH and alkalinity in water while at places also causing phosphorus loading, increase in fluoride content and high concentrations of sulphates. The anthropogenic factors affecting the water quality includes impacts due to agriculture ; use of fertilizers, manures and pesticides; animal husbandry activities; inefficient irrigation practices; deforestation of woods ; aquaculture; pollution due to industrial effluents and domestic sewage; mining and recreational activities. The anthropogenic influence causes elevated concentrations of heavy metals, Mercury, coliforms and nutrient loads.
This paper studies the effects of natural processes and human influences in rural and urban aquatic systems. The pollution due to environmental parameters such as elemental pollution, heavy metals, compounds and bacterial and pathogenic contamination for both urban and rural areas h...

...c ecosystem, but also the access to safe drinking water for human consumption. Water quality and quantity are thus intimately linked though not often measured simultaneously. Water quantity measurement is done by hydrological monitoring stations that record water level, discharge, and velocity. In contrast, water quality is determined by analysis of water samples collected by these monitoring stations periodically. However, the results of water quality monitoring are important so as to determine the spatial and temporal trends in such surface and ground waters.
Local, regional and global assessments of water quality monitoring data help in illustration of key features of aquatic environments, while explaining the positive and negative impact of human activities. Clear and concise background knowledge on water quality can further help in other water assessments.
Water pollution is a very serious problem as it affects one of the most essential ingredients to our very livelihood. The earth is covered in water, in fact about 70% of the Earth is covered in water, only
This investigation compared the water qualities of Cherry Creek and Bear Creek in order to determine how the physical, chemical, and biological factors of the streams impacted the amount of life present within them. This investigation attempts to answer the question, “How are abiotic elements related to the number and abundance of macroinvertebrates found in the two streams?” Water quality is the term used to indicate a body of water’s suitability for use (Ayers 1976). Water quality can be assessed based on its physical, chemical, and biological characteristics that it portrays (Metcalfe 1989). All of these elements interact together to create the ecosystem in which an organism lives in.
Living in a world that is roughly 70% water, and all living creatures found on this planet depend on this resource whether directly or indirectly, making water quality an important topic and vital to sustain our world of cycles. “Determination of status of water quality of a river or any other water sources is highly indeterminate. It is necessary to have a competent model to predict the status of water quality and to advice for type of water treatment for meeting different demands.” (Bai V, 2009) With most of our water on this planet made of salt water and our constant damage towards the remaining water that can be consumed by humans is diminishing with improper distribution on a global scale. If our greed comes before companionship, and our quality of life is more important than pollution, then our future generations to come will be born into a world of chaos, and a scarce of a basic human necessity.

Today's waters are constantly being treated like sewage dumps or trash cans. We use them as garbage cans every day polluting the water more and more. "Pollution is often by way of rivers, drains and outflow pipes." Causing an outflow of sewage into our ocean waters. This is not only affecting the community but also the marine life and other sea creatures living in the ocean." This pollution includes human sewage and domestic waste water, factory outflows of acids and poisonous metals, engine oil from roadside drains and garages, farm chemicals washed off the land by rain, building-site rubble, nuclear waste from power plants, and oil from wells, refineries, and tankers." Stating that most of today's waste is from factory or factory ran products that shouldn't be polluting the water
Clean and safe drinking water resources are becoming scarce as the population grows. The world is facing many problems, but the most important thing needed to survive, is water. Water is getting low in many countries, therefore residents are suffering the misfortune of not having the reliable source of clean water. Today many countries are having water shortages meaning rivers, lakes, streams and groundwater are not enough to rely on for supplying water demands. For example, California is facing a drastic water shortage, the natural water resources are not enough to fulfill their water demands.

There will growth of water born diseases increasing health hazards and degradation of environment and ecosystems. This affects the natural environment system leading to exaction of some species. And the due contamination of water can also lower the production of agriculture products and other economy activities will decrease. If there will more water bodies pollution it also has negative effects on its environment there decline of economy of the country. Since more of the country budget have invest on the health sectors. The country major users of water are agriculture, intensification hydropower and industrialization. Urbanization is another significant challenge. Rural-urban migration increases pressure on urban infrastructure and services and cause environmental problems which will lead to water pollution.
Water is one of the most essential non-renewable natural resources on the Earth. Technically, an un-hydrated human being can live no more than three days. In the United States, people consume water mainly from tap water and bottle water. However, the consumption between these two sources is not even but lean to one side heavily. According to the Natural Resources Defense Council, people consume from 240 to over 10000 times more per gallon for bottled water than they usually do for tap water. (NRDC) In addition, according to a survey from US National Library of Medicines, only 17% of the participants prefer to drink tap water exclusively.(US National Library) Compared to the bottled water which is shining like a superstar, tap water is like a diligent worker in the shade, unpopular but useful. The extremely unbalance of bottled water consumption implies that a commonly hold conception exists: bottle water is superior to tap water. In fact, scientific evidence proves that tap water is nothing different than bottle water. More importantly, the excessive consumption of bottled water is an irrational use of resources and creates severe environmental issues.
Water quality can be described as the measurement of the condition of water relative to the requirements of humans, animals and plant’s need. When we talk about water quality testing, we are highlighting a critical piece of natural observing for civil engineers in order to create a specific structure or decision. At the point when water quality is poor, it influences almost every single form of life in our planet; going from plants to animals and thereon. Hydrology, in the other hand, is the study of water. It is important to state that hydrology is a critical part for civil engineers to determine and predicting decisions that will affect our biological environment.
There are many types of pollution. The main types of pollution are water, air, soil, thermal, radioactive, noise, and light. The topic for this experiment is Water Pollution. Water Pollution became a problem in the 1900’s when water started being treated like sewage. Earth Day was founded by United States Senator Gaylord Nelson on April 22, 1970 because of 1900’s pollution. Water Pollution also affects humans and animals. There was a Cholera outbreak in 1854, before water pollution became a problem, and a Typhoid outbreak in New York from 1900 to 1915. There are multiple possible causes to Water Pollution. Humans let out chemicals into the environment, and when some of those chemicals
Wastewater is the combination of water-carried or liquid wastes starting in the sanitary conveniences of dwellings, industrial or commercial facilities. In addition to this, surface water, groundwater and storm water may also be present. It is any water that has been badly affected in quality by anthropogenic influence. It contains waste from residential, industrial and commercial processes. Municipal water contains industrial wastewater, sewage and gray water. Gray water is the water from sinks and showers. Large industries also produce wastewater.
Water Pollution is a current issue that has serious consequences; it progresses everyday in our lakes, oceans, rivers and other bodies of water.
The problem of water scarcity has increasingly spread throughout the world as of yet, The UN reports that within the next half- century up to 7 billion people in 60 countries which is more than the whole present population will face water scarcity (Sawin “Water Scarcity could Overwhelm the Next Generation”). As well the demand for freshwater has tripled over the past 50 years, and is continuing to rise as a result of population growth and economic development. 70% of this demand derives from agriculture which shows the influence of water on food supply globally as well not just drinking water (Sawin “Water Scarcity could overwhelm the Next Generation”). But increasing water use is not just a matter of the greater number of people needing it to drink and eat; it also comes from pollution and misuse of water supplies, by either dumping or runoff of bacteria or chemicals into water. This also “causes other pollutions as well such as soil and air pollution, accelerating wetland damage and human caused global warming” (Smith and Thomassey 25). According to UN report, recent estimates suggest that climate change will account for about 20 percent of the increase in global water scarcity in coming decades.
The Causes of Water Pollution Water pollution is very harmful to the environment and living things. Water pollution can come from many different sources. If the pollution comes from only one source, such as an oil spill, it is called point-source pollution. If it comes from many different sources, it is called nonpoint-source pollution. Most water pollution affects the immediate area surrounding the source, but there are some types of pollution, such as hazardous, that can affect areas miles away from the source.
