>In addition to Google’s request in the Charleston area, mega farms in central South Carolina have been under scrutiny over the amount of groundwater they use to irrigate crops each summer. 549 million gallons is about 1685 acre feet, which isn't very much irrigation water. South Carolina golf courses alone use 9.7 million gallons/day of groundwater for irrigation or 3,540 million gallons per year. SC golf courses use a combined total of groundwater and surface water of 14,991 millon gallons per year. https://waterdata.usgs.gov/sc/nwis/water_use?format=html_table&rdb_compression=file&wu_area=State+Total&wu_year=2015&wu_category=IG&wu_category_nms=Irrigation%252C%2BGolf%2BCourses https://waterdata.usgs.gov/sc/nwis/water_use?format=html_tab...
