What is Water Pollution?
Water pollution is the presence of unwanted waste material in water sources like rivers, lakes, sea, and aquifers. This pollution leads to adverse effects on the environment, people, and on other living creatures.
There are numerous reasons for water pollution and in this industrialisation period they mainly include Industrial waste and sewage, agricultural runoff, plastics and chemical poisoning. The effects of polluted water are negative such as the devastation of habitats, reduction in species, and water-borne illnesses.
Preventing water pollution is therefore an important task if humanity and all life forms on the planet are to continue living healthy lives. Measures for water pollution control involve appropriate means of disposal, treatment of sewage, minimising plastic usage and adhering to industrial policies.
Water is a necessity that can only be obtained from clean water sources that are essential for drinking and irrigation purposes. Hence, identifying ways of controlling water pollution or rather preventing water pollution is a good step towards maintaining the environment for the future generations.
Water Pollution and It’s Control?
Action of polluting water can be defined as the processes through which undesirable substances are introduced into the water sources and rendering them non-compliant with standards. This pollution poses various dangers to the ecosystem, human life and affects biodiversity.
Measures for water pollution management are those set out to reduce pollutants in water and thereby ensure that they do not reach sources of water. It covers matters such as industrial waste treatment, sewage management, prevention of agricultural pollution and plastic pollution, among others. The scalable control measures are significant for providing clean water for drinking, farming and supporting ecosystems.
Sources of Water Pollution
There are many sources of water pollution. Some of the most common sources include:
1. Sewage
2. Agricultural runoff
3. Industrial pollutants
4. Mining activities
5. Urban runoff
6. Litter and debris
7. Boat and ship traffic
8. Aquaculture
Causes of Water Pollution
As we discussed above, the main reason for water pollution is industrialisation and other significant causes. However, above all the primary reason is human activity. Let us discuss some of them in detail-
Introduction of harmful materials through human activities:
Many human activities introduce harmful materials into water bodies leading to the primary path for soil contamination by pollutants.
Industrial wastes and Chemical contamination:
The industrial waste which includes chemicals released directly into local rivers and lakes, contains heavy metals and toxins many of which are non-biodegradable in nature.
Agricultural Runoffs:
Runoff carries fertilisers, pesticides and untreated animal waste into groundwater or local streams – introducing harmful chemicals and nutrients that cause eutrophication.
Urban wastewater and Household pollution:
Urban and household wastewater also accounts for a significant portion of the water pollution, leaching pathogens, nutrients, and organic matter into natural waters. This pollution results in plastic waste that has a higher chance of clogging waterways damaging aquatic life as it takes a long time to decompose.
Oil spills and Chemical leaks:
An oil spill or a chemical leak, on the other hand has even more serious consequences as it contaminates our waters and kills marine organisms.
What are the Consequences of water pollution?
The effects of these pollution includes:
- Habitat destructions
- Loss of biodiversity.
- Transmission of waterborne diseases.
Water Pollution in India
Water pollution is a serious environmental threat in India, where river systems, lakes and groundwater reserves are contaminated by urban and industrial wastes, agricultural runoffs, and defecation by humans and animals alike. Almost all of the country’s rivers are badly polluted, including Ganges– often referred to as ‘one of the world’s dirtiest rivers’- which is used for bathing, drinking, industry, and agriculture by more than 500 million people.
Causes of water pollution in India
Controlling water pollution is a challenging task in India. It is not possible to control water pollution unless there is a thorough understanding of its source. Water pollution in India is mainly caused by-
- Organic wastes
- Chemical wastes
- Industrial wastes due to rapid industrialization
- Urbanization and agricultural modernization
Effects of Water Pollution
- Waterborne Diseases: Contaminated water can carry harmful bacteria, viruses, and parasites, causing illnesses like cholera, dysentery, typhoid, and hepatitis, leading to severe gastrointestinal issues and potentially death.
- Skin Infections: Contact with polluted water during activities like swimming or bathing can result in skin conditions such as dermatitis and rashes, often requiring medical attention.
- Long-Term Health Effects: Prolonged exposure to pollutants like heavy metals, pesticides, and chemicals can lead to chronic health issues, including cancer, neurological disorders, reproductive problems, and developmental abnormalities.
- Effects on Aquatic Ecosystems: Water pollution disrupts aquatic ecosystems, harming aquatic life and the overall food chain.
- Eutrophication: Excessive nutrients from runoff and sewage cause eutrophication, leading to algal blooms that deplete oxygen, creating dead zones in water bodies.
- Habitat Destruction: Pollutants like industrial waste and oil spills destroy aquatic habitats, leading to biodiversity loss and harming marine life.
- Economic Impacts: Water pollution negatively affects industries such as fishing, tourism, and agriculture, leading to increased costs for water treatment and public health concerns.
