Which of the following statements is incorrect about the overuse of groundwater by some of the Indian states?

 Intensive irrigation in Punjab, Haryana, and western Uttar Pradesh is decreasing the salinity in the soil 

In Punjab, Haryana and western Uttar Pradesh, more than 85 per cent of their net sown area is under irrigation. Wheat and rice are grown mainly with the help of irrigation in these states. Of the total net irrigated area 76.1 per cent in Punjab and 51.3 per cent in Haryana are irrigated through wells and tubewells. This shows that these states utilise large proportion of their groundwater potential which has resulted in groundwater depletion in these states. The over-use of groundwater resources has led to decline in groundwater table in these states. In fact, over-withdrawals in some states, like Rajasthan and Maharashtra, have increased fluoride concentration in groundwater, and this practice has led to increase in concentration of arsenic in parts of West Bengal and Bihar. Intensive irrigation in Punjab, Haryana and western Uttar Pradesh is increasing salinity in the soil and depletion of groundwater irrigation.
