148 REPORT OF INVESTIGATIONS NO. 50 to the sea during wet periods, yet most streams go dry during droughts. If holding basins can be obtained and economical water treatment methods developed, much of this water can be stored in the Floridan aquifer where it will tend to improve the quality of the ground water, raise artesian water levels, and prevent salt-water intrusion. A detailed study and a pilot project on artificial recharge would help to develop methods and evaluate its feasibility in insuring a continuous adequate water supply for Orange County and the east-central Florida region.
