Consider the following statements: 1. 36% of India's districts are classified as "overexploited" or "critical" by the Central Ground Water Authority (CGWA). 2. CGWA was formed under the Environment (Protection) Act. 3. India has the largest area under groundwater irrigation in the world. Which of the statements given above is/are correct?

1. Incorrect. The commonly cited figure is about 29% of assessment units/blocks/taluks/mandals being overexploited, critical or semi-critical; saying 36% of India's districts are overexploited or critical is not the standard CGWA/groundwater assessment fact.
2. Correct. CGWA was constituted under Section 3(3) of the Environment (Protection) Act, 1986.
3. Correct. India has the largest area under groundwater irrigation in the world.
Therefore, statements 2 and 3 only are correct.
