India is an agricultural-based country, and groundwater is the major water source for Indian farmers. A study has been conducted to examine the trends and variability of groundwater levels that occurred over the past 20 years from 1999 to 2018 in Bhiwani district, Haryana, India. To better understand the trends and variability, the duration is further divided into two halves from 1999 to 2008 and 2009 to 2018. It has been seen that over the 20 years, the groundwater level had decreased 0.178 meters yearly. The least-square method (LSM) has been used for the trend analysis and coefficient of variance for computing variability. Further, the seasonal groundwater well data were collected throughout the district. After mapping out the groundwater levels, it has been observed that, in the southern and western regions of the district depicting water scarcity condition whereas, in the district's northern and eastern region, the groundwater levels are fair enough. From the yearly analysis is ha
