4.2.2. Prevention of Water Pollution

Available water resources are degrading rapidly. The major rivers of the country generally retain better water quality in less densely populated upper stretches in hilly areas. In plains, river water is used intensively for irrigation, drinking, domestic and industrial purposes.

Water resources are diminishing quickly due to pollution, especially in areas with dense populations. In the upper regions of rivers, where populations are lower, the water quality remains better. However, in more populated plains, the water is heavily used for various needs, leading to increased pollution levels.

Think of a local park that has many visitors every day. While the areas in the park that are less frequented remain clean and pristine, the spots where people gather for picnics, sports, and activities may quickly become littered and polluted. Similarly, rivers in less populated regions are like the secluded areas of the park, while those in populous areas face the 'crowding' issue, leading to declining quality.

The drains carrying agricultural (fertilizers and insecticides), domestic (solid and liquid wastes), and industrial effluents join the rivers. The concentration of pollutants in rivers, especially remains very high during the summer season when flow of water is low.

Pollution enters rivers through various drains that carry waste from agricultural fields, households, and industries. During the summer, when water levels drop in rivers, the concentration of these pollutants increases, making the water quality worse.

Imagine a sponge soaked in water that is clear. Now, if you start pouring dirt and food through it, the water at the bottom will quickly turn murky. This is akin to what happens in rivers; as more waste enters during low water seasons, the quality drops significantly.

Groundwater pollution has occurred due to high concentrations of heavy/toxic metals, fluoride, and nitrates at different parts of the country.

Various industrial processes lead to the release of harmful substances into groundwater, decreasing its quality. High levels of toxic metals, fluoride, and nitrates pose threats not just to the environment but also to human health.

Consider how a factory might dump waste into a nearby river without filtration. This waste can seep into the ground and contaminate drinking water supplies like a leaking roof allows rainwater to spoil stored food. This connection to real-world consequences highlights the severity of groundwater pollution.

The legislative provisions such as the Water (Prevention and Control of Pollution) Act 1974, and Environment Protection Act 1986 have not been implemented effectively.

Even though laws exist to manage and protect water resources, their enforcement has been weak. This poor implementation means that polluting activities continue, leading to further degradation of water quality.

Think about school rules that are never enforced. Students might continue to break them without consequence, just as businesses might keep polluting if laws aren't properly upheld. The lack of enforcement leads to ongoing problems in both cases.

There is a strong need to generate public awareness about the importance of water and impacts of water pollution.

Increasing public awareness can trigger community action to address pollution issues. People need to understand the relationship between clean water and their health, the environment, and the economy.

When communities come together for a cause, like a clean-up day, they start to understand the importance of preserving their environment. It’s similar to when you learn about recycling; once you realize its benefits, you're more motivated to participate actively.

The Central and State Governments have initiated many watershed development and management programmes in the country. Some of these are being implemented by non-governmental organisations also.

Government initiatives are crucial for managing water resources and tackling pollution. Community organizations are often involved in these efforts, emphasizing collaboration to achieve better results.

Think of a school project where students are divided into groups. If everyone contributes their part, from researching to presenting, the project turns out well. Similarly, tackling water pollution needs combined efforts from both the government and communities to be effective.

Another way through which we can improve fresh water availability is by recycle and reuse. Use of water of lesser quality such as reclaimed water for drinking, irrigation, fisheries and afforestation.

Recycling water is essential for improving its availability. Water that can no longer be used for drinking might still be suitable for other purposes, such as irrigation or fisheries, allowing fresh water to be conserved.

Imagine refilling a plastic bottle with clean water and then, once emptied, using it to water your plants instead of tossing it. By doing this, you're conserving more fresh water for drinking, much like recycling can conserve water in larger systems.
