Difficulty: MediumInference and Logical Deduction

Read the following passage carefully:

In recent years, the implementation of the National Decentralized Groundwater Recharge Scheme has mandated that industrial units operating within designated over-exploited hydrological blocks must recycle at least 70%70\% of their wastewater for secondary operational processes. Additionally, factories achieving a zero-liquid discharge milestone receive a 15%15\% reduction in their annual municipal water tariff. However, recent state audit reports indicate that while overall industrial water withdrawal from deep aquifers has declined by 12%12\% across these blocks, local surface water pollution levels have marginally increased. Environmental economists argue that the financial rebate creates a strong incentive for factories to substitute subsurface extraction with untreated surface water draws from nearby canals, effectively shifting the locus of ecological strain rather than reducing total water consumption. Crucially, the current regulatory framework lacks mandatory real-time monitoring devices for surface water intake, relying instead on self-reported quarterly logs submitted by industrial managers.

Based strictly on the passage provided above, which of the following conclusions can be logically inferred regarding the National Decentralized Groundwater Recharge Scheme?

  1. The current scheme's regulatory structure permits industrial units to satisfy groundwater conservation requirements without necessarily diminishing their overall intake from natural water systems.Answer
  2. B
    The financial tariff rebate has proven ineffective because zero-liquid discharge technology is economically unviable for small-scale industrial operations.
  3. C
    Mandating real-time digital monitoring devices on canal intake points will immediately eliminate industrial surface water pollution.
  4. D
    Industrial units in designated over-exploited blocks are completely barred from extracting any water from deep subsurface aquifers.

Answer

The current scheme's regulatory structure permits industrial units to satisfy groundwater conservation requirements without necessarily diminishing their overall intake from natural water systems.
The passage explicitly describes how factories reduced groundwater extraction by 12% to meet policy goals while simultaneously increasing surface water draw from canals to claim financial rebates. Combined with the absence of real-time surface water monitoring, this directly confirms that the regulatory framework allows units to meet groundwater targets by shifting water sources rather than decreasing total water intake.

Step-by-Step Solution

1
Analyze the explicit facts presented in the passage
The passage states that deep groundwater extraction dropped by 12%, but surface water draws increased because factories sought the 15% tariff reduction by shifting their source of water rather than lowering total usage.
Establishing the premise relationships between groundwater policy incentives and observed shift in water intake sources.
2
Evaluate the regulatory conditions mentioned
The current framework relies on self-reported logs and lacks real-time monitoring of surface water intake.
Identifying why factories are able to substitute groundwater extraction with unmonitored surface water draws.
3
Deduce the necessary logical conclusion strictly supported by the text
Industrial units can meet the mandate of reducing groundwater reliance while continuing to strain natural water bodies (canal surface water).
Selecting the option that expresses this exact logical implication without adding outside assumptions.
