The Importance Of Geology

The lead in the environment is formed naturally in the earth’s crust mainly as Lead Sulphide. The main exposure channels of lead entering the environment through atmospheric lead is predominantly from automobile emissions. Other lead exposure routes include lead-acid batteries, paint chips, fertilizers, utilized ammunition, pesticides, and other industrial byproducts. The means of conveying lead from key emission sources is mainly through the air. Concerning the sources of lead in drinking water, normally lead reaches into the residents’ water after it is channeled from their water treatment plant or the wells. To be more precise, the source of lead in people’s water supply largely emanates from their households’ pipes or lead solder from plumbing. The most typical cause of the lead formation is from the corrosion reaction by the lead pipes or solders and the water. The acidity as a result of the low pH, dissolved oxygen, and little mineral contents in the water are main reasons of the corrosion. The lead amounts in the water become high if the water spends a long duration of time stagnated inside the old pipes.

     Heavy metals, such as copper, lead, mercury, and selenium are another group of toxins that pollute the water as well as the rest of the environment. The source of many of these pollutants are industries, automobile exhaust, mines, and even natural soil.

There are three main mechanisms by which the chemical composition of groundwater, which is our natural source of drinking water, may be changed: by natural processes, by man's waste-disposal practices such as those for sanitary wastes, liquid industrial wastes, solid wastes, and radioactive wastes, and by spills, leaks, and agricultural activities and other sources unrelated to disposal. The degree of risk posed by contaminants varies according to many factors. These include the volume and toxicity of the contaminant, its concentration in the aquifer, its persistence in the environment, and the degree of human and environmental exposure to the contaminant. In addition, the number of persons affected, or likely to be affected, over time and the percentage of available groundwater both locally and regionally should be taken into consideration. If the contaminants in the groundwater exceed the standards set for drinking water by the federal government, for example, then the water is hazardous for the use for which it was designated under the standards. These standards include, however, only a limited number of chemicals, and thus they do not necessarily protect humans or the environment against either the short-term or the long-term effects of every contaminant that might be found in

This situation showcases the major dependency on the unique physical and chemical properties of water by displaying the results of water contamination. The switch from Detroit to Flint water system proved to be a fatal decision as the chemical and physical properties of the water were altered by both the iron and lead metals. The addition of high levels of chloride left the water exposed to contamination of lead and iron. The corrosion of the pipes occurred when the chlorine disinfectant reacted with the elemental metals of iron and lead. The chemical property of water was altered with these high levels of lead, chloride, and iron. This contamination also left the water with different physical properties such as a reddish-brown colour and a pungent odour as opposed to a colourless and odourless liquid. The manipulated physical and chemical properties of water led to irritability, developmental delay, learning difficulties, hearing loss, and many more. Thus, this situation showcases how living things depend for their survival on the unique physical and chemical properties of water as with these alterations it can lead to lethal consequences.

According to ( Compton's by Britannica, 2011, SIRS discover) Lead is found in tap water and other water sources which is toxic metal

Water pollution has become a huge factor in the crisis of earth contamination. It is defined as the addition of harmful chemicals to natural water. Sources of water pollution include industrial waste, marine dumping, global warming, oil pollution,

The environmental issue of interest is clean drinking water and the abuse of our water sources. The interest in this discipline is because clean water and water abuse have been an issue for many years. Many countries around the world and in our own back yard lack clean drinking water. The cause of unclean water can be caused by bad agriculture practices and industrialization. The cause of these unhealthy practices may cause waters to be contaminated with a mineral called Chromium; this mineral exposes a high risk of cancer. The county of Gwinnett is full of lakes, rivers, streams, creeks and ponds but the only source of drinking water that is disposed to residents comes from a man-made lake called Lake Lanier. The lake provides clean drinking

Water pollution impacts how humans and other living organisms live their life. Most common way humans are effected by water pollution is through diseases while drinking the water. Scientists have found over “five hundred different types of diseases” that can affect humans. (Book). These diseases get into the water streams by human and animal wastes. The diseases in the water can often lead to death for humans. Recent research has shown that that each year

The health hazards for humans who come in contact with contaminants from exposure to polluted water can have long term effects on the body causing possible organ failure and death. Contaminants and chemicals such lead and mercury can bring about many minor illnesses ranging from nausea, lung irritation, skin rash, vomiting, and dizziness, to the major diseases that include cancer, liver and kidney damage, disorders of the nervous system, damage to the immune system, birth defects and even death.

Groundwater pollution is a major problem that is growing in all over the world. Of course the united states America also facing this problem. People of Mississippi State are worried about groundwater pollution due to the several human activities. Groundwater is a main source of their water supply. Disposal of solid waste in landfills is an economic option for many municipalities in developing countries where alternatives like incineration and composting are costly. However, groundwater pollution from the leachate generated within the landfill and migrating through the bottom liner material into the underlying groundwater aquifers remains a major public health concern I studied chemical parameters of groundwater in Alcorn State University as a part of my project.

Three main ways our public drinking waters can become contaminated are by agricultural runoff, which have effects that go all the way from the effects of the remnants left behind from sprayed pesticides and unmanaged animal feces. Second, we have an oil and coal industry that just never stops. What comes from our oil industry ultimately ends up changing and altering the biology of the surrounding water with thermal pollution, and in some cases I have seen this reported as just as if not more damaging than bacterial or sedimentary pollution. The coal industry pollutes surrounding waters with sulfides from leaching. Illustrations are given below.

Although municipal water can contain a vast array of contaminants, several continued to repeatedly show up in water of the cities studied. Among the most frequently found contaminants were Arsenic, mentioned earlier, and other toxic chemicals such as radon, the rocket fuel perchlorate and other carcinogens, which may cause skin problems, birth defects, reproductive problems and even cancer. High Volumes of Lead were found, which enters the drinking water supplies from the corrosion of old pipes and

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical or sensory changes such as elevated temperature and discoloration. While many of the chemicals and substances that are regulated may be naturally occurring (calcium, sodium, iron, manganese,
