Nearly 90 percent of all municipal withdrawals are from the Biscayne aquifer, which also supplies 200 million gallons per day for agriculture, irrigation, industry, mining, and recreational purposes. Municipal withdrawals in Broward, Dade, and Palm Beach Counties have increased 700 percent over 45 years, increasing from less than 100 million gallons per day in 1950 to nearly 800 million gallons per day in 1995. By the year 2020, municipal water demands are projected to reach 1,200 million gallons per day and serve 6 million people. Increased withdrawals from the Biscayne aquifer have combined with substantial land-use changes to affect the balance between freshwater and saltwater in the ground-water flow system.
