Summary

A report indicates that Sewage Treatment Plants (STPs) in Delhi are not meeting the prescribed discharge norms, leading to concerns about water pollution and public health. This failure underscores the need for better monitoring, maintenance, and upgrading of STPs to ensure effective wastewater treatment. The situation also highlights the importance of stringent enforcement of environmental standards to protect water resources.

Background

Sewage treatment in India has historically been inadequate, leading to significant water pollution. The Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs) are responsible for monitoring and enforcing environmental standards.

Latest Developments

The news highlights the failure of Delhi's STPs to meet discharge norms, indicating systemic issues in wastewater management. This can lead to increased pollution levels in the Yamuna River and other water bodies.

Practice Questions (MCQs)

1. Consider the following statements regarding Sewage Treatment Plants (STPs) in India: 1. STPs primarily aim to reduce the levels of Biochemical Oxygen Demand (BOD) and Total Suspended Solids (TSS) in wastewater. 2. The Central Pollution Control Board (CPCB) sets the discharge standards for STPs across the country. 3. The National Green Tribunal (NGT) has no jurisdiction over the functioning and compliance of STPs. Which of the statements given above is/are correct?

A.1 and 2 only
B.2 and 3 only
C.1 and 3 only
D.1, 2 and 3

Show Answer

Answer: A

Statement 1 is correct as STPs reduce BOD and TSS. Statement 2 is correct as CPCB sets discharge standards. Statement 3 is incorrect as NGT has jurisdiction over environmental matters, including STP compliance.

2. Which of the following parameters is NOT typically used to assess the performance of a Sewage Treatment Plant (STP)?

A.Biochemical Oxygen Demand (BOD)
B.Chemical Oxygen Demand (COD)
C.Total Dissolved Solids (TDS)
D.Gross Domestic Product (GDP)

Show Answer

Answer: D

GDP is an economic indicator and not a parameter for assessing STP performance. BOD, COD, and TDS are all relevant parameters.

3. In the context of the Water (Prevention and Control of Pollution) Act, 1974, which of the following statements is/are correct? 1. The Act empowers the Central Pollution Control Board (CPCB) to set standards for water quality. 2. The Act provides for penalties for non-compliance with the prescribed standards. 3. The Act applies only to surface water sources and not to groundwater.

A.1 and 2 only
B.2 and 3 only
C.1 and 3 only
D.1, 2 and 3

Show Answer

Answer: A

Statements 1 and 2 are correct. The Act empowers CPCB and provides for penalties. Statement 3 is incorrect as the Act covers both surface and groundwater.

4. Assertion (A): Many Sewage Treatment Plants (STPs) in India fail to meet the prescribed discharge norms. Reason (R): Inadequate infrastructure, lack of maintenance, and insufficient monitoring contribute to the poor performance of STPs. In the context of the above statements, which of the following is correct?

A.Both A and R are true, and R is the correct explanation of A
B.Both A and R are true, but R is NOT the correct explanation of A
C.A is true, but R is false
D.A is false, but R is true

Show Answer

Answer: A

Both the assertion and the reason are true, and the reason correctly explains why many STPs fail to meet discharge norms.
