What industry uses most of the groundwater pumped every year

Agriculture

Explanation:

There are two sources of water, Surface water, and Groundwater. In the USA most of the groundwater is used in the Agriculture sector. Almost forty percent of the water used in irrigation is the groundwater. It is used to irrigate eggplant, squash and other crops. Water departments at the county level also withdraw a large amount of groundwater for businesses and industries. Mining facilities also use lots of groundwater. According to the 2015 statistics of the US government, 15,200 Million gallons of water was withdrawn every day from ground. California, Arkansas, Nebraska, Idaho, and Texas were the five states which had a 46 percent share of the total groundwater extracted. Saline groundwater is used in mining
