From July 1972 to June 1973, 78 5,200 metric tons or 5,700 tons of the total nitrogen and 90 207 metric tons or 228 tons of the total phosphorus entering the conservation areas was contributed by bulk precipitation rainfall and dry fallout. Controlled and noncontrolled surface-water discharge contributed the remainder 22 1,460 metric tons or 1,610 tons of total nitrogen and 10 22.4 metric tons or 24.7 tons of total phosphorus. Most surface-water loads, 90 of the total nitrogen 696 metric tons or 767 tons and 88 of the total phosphorus 5.2 metric tons or 5.7 tons leaving the conservation areas entered Everglades National Park. About 5,000 metric tons 5,500 tons of total nitrogen and nearly 220 metric tons 242 tons of total phosphorus were apparently retained within the conservation areas.
