Background Context
The history of water contamination in India is deeply intertwined with urbanization, industrialization, and agricultural practices. Traditional water management systems, such as tanks and stepwells, were effective in localized areas but couldn't cope with the demands of rapidly growing populations and industrial activities. The British colonial era saw the introduction of piped water systems in major cities, but these were often inadequate and poorly maintained. Post-independence, the Green Revolution, while boosting agricultural output, also led to increased use of fertilizers and pesticides, contributing to groundwater contamination. The lack of comprehensive water management policies and enforcement mechanisms has exacerbated the problem over the decades, leading to the current crisis.
Current Developments
In recent years, there has been increased focus on water quality monitoring and treatment technologies. The Jal Jeevan Mission, launched in 2019, aims to provide safe and adequate drinking water to all rural households by 2024. However, challenges remain in ensuring the sustainability of water sources and the effectiveness of treatment processes. Emerging contaminants, such as microplastics and pharmaceuticals, are also posing new threats. Future outlook involves greater emphasis on decentralized water management, rainwater harvesting, and community participation in water quality monitoring. Technological advancements in water purification and sensor-based monitoring systems are expected to play a crucial role in addressing the water contamination crisis.
Key Facts
- Aging infrastructure: Causes water contamination
- Health risks: Posed by contaminated water
- Need for: Infrastructure upgrades and sanitation
Practice MCQs
Question 1
Consider the following statements regarding the causes of water contamination in India:
1. Untreated sewage discharge into water bodies.
2. Over-extraction of groundwater leading to arsenic contamination.
3. Lack of stringent enforcement of environmental regulations.
Which of the statements given above is/are correct?
- 1 and 2 only
- 2 and 3 only
- 1 and 3 only
- 1, 2 and 3
Explanation: All the given statements are correct. Untreated sewage, over-extraction of groundwater, and weak enforcement of regulations all contribute to water contamination in India.
Question 2
With reference to the Jal Jeevan Mission, which of the following statements is/are correct?
1. It aims to provide safe and adequate drinking water to all rural households by 2024.
2. It focuses solely on providing piped water connections and neglects water source sustainability.
3. It is implemented by the Ministry of Rural Development in collaboration with state governments.
Select the correct answer using the code given below:
- 1 only
- 1 and 3 only
- 2 and 3 only
- 1, 2 and 3
Explanation: Statement 1 is correct. Statement 2 is incorrect as the mission also focuses on source sustainability. Statement 3 is incorrect as it is implemented by the Department of Drinking Water and Sanitation under the Ministry of Jal Shakti.
Question 3
Which of the following contaminants is most likely to be found in groundwater due to over-extraction for irrigation in certain parts of India?
- Lead
- Arsenic
- Mercury
- Cadmium
Explanation: Arsenic contamination is a significant concern in groundwater in areas with over-extraction, particularly in the Indo-Gangetic plains.
Question 4
Assertion (A): Aging water infrastructure in India contributes significantly to water contamination.
Reason (R): Leaks and corrosion in old pipelines allow pollutants to enter the water supply.
In the context of the above statements, which of the following is correct?
- Both A and R are true and R is the correct explanation of A
- Both A and R are true but R is NOT the correct explanation of A
- A is true but R is false
- A is false but R is true
Explanation: The assertion and reason are both true, and the reason correctly explains why aging infrastructure leads to contamination.
