Estimated withdrawals and use of freshwater in New Hampshire, 1990
Laura Medalie, M.A. Horn
1994, Water-Resources Investigations Report 93-4096
Estimated freshwater withdrawals during 1990 in New Hampshire totaled about 422 million gallons per day from ground-water and surface-water sources. The largest withdrawals were for thermoelectric-power generation (60 percent), public supply (23 percent), and industrial use (9 percent). Most withdrawals, 358 million gallons per day, were made from surface- water...
