Water Contamination
With the development of the human society, environmental problem has become increasingly serious. Environmental conservation, as a solution, has also aroused people’s wide concern. As one of the major parts of the environment, as well as the most important resource for human, water is a worth discussing topic.
The following paragraphs will mainly introduce you about the water contamination, which is a loss of water’s use value, caused by harmful chemical substance.
The cause of water contamination, those chemicals, have several sources. The first source is the domestic sewage. It contains only 0.1 percent of pollutants, and 99.9 percent of water. Although it seems that the domestic sewage is somewhat harmless, the 0.1 percent of pollutants can pose a large risk on water body. The pollutants mainly comes from detergent, sanitary sewage, and waste. The polluted water is non-poisonous, but carries

The most serious problem is that it can affect people’s health. Some pollutants exist in the form of water solution. When people drink water, those chemicals enter human’s body easily, and problems may appear. Infectious disease is one of the problems. Virus survived in the polluted water can invade into the body defense system through the drinking process. Heavy metals also cause some trouble. When people take water contains heavy metals, chronic intoxication, teratogenesis, and cancer may occur. Another problem is the lack of clear water supply. Water shortage is nothing new for the world. Thirty percent of clear water is groundwater, when groundwater is polluted, we may experience a large loss of clear water supply. At that time, the problem of water scarcity become more obvious. Aquatic organism may also suffer from the water contamination. Heavy metals may causes death to some species, and unexpected nutrients may lead to an unbalanced situation for
Wastewater contributes about the third most nitrogen and phosphorus that pollutes the Chesapeake Bay. Wastewater comes from sewage treatment plants, which are point sources. Several factories and power plants also release pollutants into the water. They also release chemicals into the air, where they can fall down onto the bay and affect the organisms. Non-point source pollution harms many organisms from the substances the runoff picks up.
“Carried by snow melt, rain water, and groundwater, NPS pollution contributes sediments, nutrients (nitrogen and phosphorus), toxic substances, and pathogens to water bodies” (Maine Rivers 2005, ijc 2008). The Non Point Pollution generally due to stormwater in the downstream portion of the river; which are the most populated areas situated near the estuary;With the stormwater large amounts of pollutants are washed off to the river because of the impenetrable surfaces of that area which does not allow water to seep into the ground. Other sources of Nonpoint pollution are seepage from broken sewage and septic tanks, runoff from construction sites ,nutrients,sediments and chemicals from agricultural farms and roads. According to the report of International Joint Commission in 2008; “This untreated runoff may contain litter, dust, soil, oil and grease from roads, garden waste, chemicals, and nutrients and pathogens from animal feces and fertilizers” (IJC
Drinking contaminated water can cause different types of cancers and also infertility and birth defects due to of the presence hazardous chemicals. Impoundments that have not been built or properly closed off have led to the death of many animals and also health issues in
The serious threat to the health of the IRL is the reduced water quality due to the manmade hydrologic changes, non-point pollution, loss
This pollutes the groundwater and puts the health of everyone that uses the groundwater into risk, as consuming too much
Around the globe every minute a child dies because of water-related disease, Women spend hours walking to collect water, it has been estimated 1 in 9 people lack access to safe water, hospital bed spaces are occupied majorly people related to water-borne diseases. Clean water is essential for both mental and physical development. Lead in tap water causes many birth defects. Thousands of contaminants are present in tap water which are even poisonous. For every spent on water and sanitation there is a double return to the economic.
Dennis B. Blanton describes how causing more and more freshwater is becoming brackish causing fresh water to become scarce. To be able to get drinking water, the colonists dug wells across the land. However, the wells became vulnerable to drought and salt water intrusion. He also talks about how the transition affects the water. Due to the saltwater transition, and the filth within the water, the water was the reason for many diseases.
"The contaminates can have dire effects on entire ecosystems, making life more difficult for humans, plants and animals. " All living things can get sick from all the chemicals polluting everywhere they inhabit. The effects that pollution can have on the body are long
Drinking water sources have been contaminated with explosive methane, as well as other dangerous substances, such as benzene and arsenic, that can cause cancer and other serious illnesses. Toxic chemicals, as well as erosion and runoff from drilling operations, have fouled
Two impacts due to salinity are; the impact on water quality for animals
Prior to, another current problem is that algal blooms contain cyanobacteria, which in some conditions can produce toxins that can contaminate drinking water and cause harm to the local ecosystem. Lastly, a current problem is that Lake Erie attracts millions of visitors for beaches and fishing and people are not going to those attractions. These problems play a huge impact on the community. The fertilizer impacts the community because it pollutes the water that we drink. Next, the toxins that pollute the water contaminate the water and it can kill people or harm people into severe conditions.
Intro: Water pollution has caused so many problems to our waterways that no one really knows how to help. Water pollution caused; dead zones, oil spills, garbage floating around, and unsafe drinking water. People disagree about water pollution because, people have found ways to improve and help out the problem that water pollution has caused around the world. Others believe that that water pollution has created situations and are in the process of figuring out solutions. Marine life habitats are getting destroyed, marine life is declining everyday, how and where the garbage is getting into the oceans, and the drinking water is becoming seriously unsafe to drink.
Stop Taking Clean Water for Granted Can you stop for a moment and think what would happen if we didn’t have water; clean water? It seems impossible, as we use water to drink, cook, clean, grow things, and for everything else in life. Unfortunately, because of the easy access to one of the most plentiful, and most valuable resources in the world, some people take water for granted. In contrast, other poor people live in places where the only easy way to get water is from a dirty irrigation ditch. Or their only source of water is backyard faucet shared by several homes.
1. Introduction Water is crucial to our survival! Water is one of the scarcest commodities in the world at the moment; some argue that it is scarcer than oil. Wars have been fought over oil; therefore a war over water is a very big possibility in the years to come on this planet. With the current growth of the world’s population and the increase in demand for water in the agricultural industry, the issue of water scarcity is very likely to get worse and worse (Gupta, 2016).
Water is one of the most important and vital substance on earth. All life forms on earth require water to survive. If there will be no water there would be no life on earth. Aside from drinking water to survive, people have many other uses for water.
