Step 1: Understanding Section 24 of the Act.
Section 24 of the Water (Prevention and Control of Pollution) Act, 1974 prohibits any person or industry from knowingly discharging any poisonous, noxious, or polluting matter into any stream or well, thereby causing pollution. It directly relates to cases where untreated industrial effluents are released into water bodies.
Step 2: Application to the problem.
In the given case, the company discharged untreated industrial waste into a river, which led to water pollution and health hazards for the public and aquatic life. This act clearly violates Section 24 of the Water Act, 1974.
Step 3: Analysis of options.
(A) Incorrect — The company’s actions clearly violate environmental laws.
(B) Incorrect — Section 23 deals with the powers of entry and inspection, not pollution discharge.
(C) Correct — Section 24 prohibits polluting discharges into water bodies.
(D) Incorrect — Section 40 concerns offences by government departments, not private companies.
Step 4: Conclusion.
Thus, the manufacturing company is guilty of violating Section 24 of the Water (Prevention and Control of Pollution) Act, 1974.
