Causes of water pollution
1) Water pollution may be caused by the intentional or unintentional disposal of hazardous chemicals and materials into a body of water.
2) Rainfall may cause polluted landscapes to disperse their poisonous materials into the water and poison the surrounding water.
3) Water pollution may also be caused by specific points or contributing factors such as large factories, oil refineries, construction sites, chemical waste management facilities, dump sites and other large scale operations that store/produce large amounts of chemical/hazardous waste.
Effects of water pollution
1) Toxic rainfall can occur in areas where water and/or air is polluted with toxic chemicals and materials.
2) Polluted water can lead to sickness, disease, infections, deformities and even death among animals and plant life.
3) Once water becomes polluted it can affect people and animals either directly through consumption or indirectly through food sources, land degradation and the overabundance of plants and algae which can cover the surface of various bodies of water making it undrinkable and affecting the animals that live in that body of water.
Solution:
The most critical step to prevent water pollution is to adopt appropriate waste management policies. Setting up of wastewater treatment plants can resolve this issue and hence we can protect our natural water resources from contamination and embrace an eco-friendly life.
HOW YOU CAN HELPIf you would like to limit the amount of pollution you produce and thus help keep the oceans, rivers and lakes clean there are a number of things you can do.
- Replace your air fresheners with eco-friendly candles, incense and/or potpourri
- Purchase environmentally friendly cleaning products that do not harm the land if they happen to be flushed or emptied into a drain
- Reduce the amount of power you use and purchase energy saving light bulbs and appliances. This helps reduce the amount of emissions being released by utility companies and your own home products.
- Conserve your water usage and don’t leave water running when you are not using it
- Reduce, recycle & reuse materials that you have purchased. Plastics and papers may be sent to the recycling bin while some of your glass materials may be able to be reused or re-purposed
- Make sure non recyclable waste is contained properly so that it does not spill into the land, street drain sewage drain
- Purchase local food that has been grown from healthy agricultural farms that don’t use polluting fertilizers and pesticides
- Purchase eco-friendly lawn fertilizers and pesticides for your own lawn in order to prevent your lawn from becoming toxic and prevent possible hazardass chemicals from entering street drains
- Recycle old clothing by giving it away to shelters and non for profit re sellers. Not only does it lower the amount of garbage you produce it also allows you go give to a cause and help the community
- Use a reusable grocery bag rather than the plastic bags offered at grocery stores when shopping for food to minimize your plastic waste
- Eliminate unnecessary mail and have your bills sent to you by email. This helps protect the trees and reduce the amount of paper you have to dispose of later

Hello everybody, now I am going to tell you about water pollution, a serious problem. First, the definition of it is the contamination of bodies of water such as lakes, rivers, oceans and groundwater. There are two reasons why they are polluted: point source pollutants and non- point source pollutamt. Point source pollutants are industrial waste, sewage, pesticides, herbicides. Non-point pollutants are pollutants from storm water and atmosphere. There are a lot of effects that water pollution may cause. Human and animals may die if they drink contaminated water. Plants will be killed by pollutants as well. So what we can do to solve the problem? Goverment should give heavy fines to companies that are found doing this. We also educate companies about the environment and give tax breaks to companies that find “clean” ways to dispose of their waste.

Essay on Water Pollution – Essay 2 (250 Words)
Introduction:
The consumption of water forms a large part of our physical health. Aside from this obvious fact, water is an important aspect of our ecosystem. However, for water to perform its various functions, it has to be kept pure as contaminated water would lead to adverse environmental and health consequences.
Water pollution is the introduction of foreign material into our water bodies like lakes, streams, rivers or groundwater. This introduction, 9 times out of 10 is usually a result of human interference. Through various activities, sometimes inadvertently, we pollute our ecosystem with toxic materials dumped into our water.
Causes of Water Pollution:
One of the most popular features of water is also the cause of water pollution. Water is a “Universal Solvent” which simply means that it can dissolve almost any substance. Consequently, it is also why toxic substance mixes with water effortlessly. These toxic materials could be from traceable sources such as factories, farms, sewage etc. They are sometimes less traceable sources such as pollution in the air.
Water Pollution Effect on our Environment:
The first organisms that come in contact with polluted water are creatures living in the water. The effect of water pollution on aquatic animals depends on the kind of material introduced into the water. In extreme cases, it can lead to death of aqua species. It can also lead to a serious disrupting of the food chain. Finally, water pollution can lead to serious diseases in humans such as cholera and hepatitis.
Preventive Measures:
While the obvious way to reduce or eliminate water pollution is to stop industrial waste, doing just that and nothing more would not be enough. Preventive measures such as reduction in plastic consumption, controlling leaks in cars, using fewer pesticides or efficient disposal of chemicals would help us go the extra mile.

Nowadays, one of the biggest problems human are facing with is water pollution. Water pollution is defined as the presence in groundwater of toxic chemicals and biological agents that exceed what is naturally found in the water and may pose a threat to human health and/or the environment. A lot of causes are responsible for this issue. And they lead to extremely bad consequences. I’d like to explain more in the following paragraphs.
Some typical causes of water pollution are Industrial waste, Sewage and waste water, Mining activities, Accidental Oil leakage, Burning of fossil fuels, Chemical fertilizers and pesticides, … These agents contribiute to water pollution.
And the consequences? Of course, it is human health! Human are likely to get into trouble with some diseases such as hepatitis by eating seafood that has been poisoned. Water pollution also brings about the death of aquatic (water) animals, Disruption of food-chains, Destruction of ecosystems.
In conclusion, water pollution is a alarming problem that needs to be solved as soon as possible. The sooner we solve it, the more healthy we are.

Water pollution is the pollution of bodies of water, such as lakes, rivers, seas, the oceans, as well as groudwater. It occurs when pollutants reach these bodies of water, without treatment. Waste from homes, factories and other buildings get into the water bodies.
Water pollution is a problem for the species and ecosystems there. It affects plants and organisms living in the water. In almost all cases the effect is damaging not only to individual species and populations, but also to the wider biological communities. The color is usually green or brown but normal water can be blue.
Agriculture is one of the major sources of water pollution, because the fertilizers given to the crops for better growth are washed into rivers and lakes, which in large amounts pollute the water.
There are many chemicals that are naturally found in these bodies of water but today it is polluted by nitrates, phosphates, oil, acid from acid rain, and debris like sediments, fallen logs and so on.
