feet of the surface. The artesian pressure head ranged from 170 to 177

feet above sea level during the period of record. The artesian pressure

head rose about 3 feet from May 1959 to July 1960, then declined about
2 feet until February 1961. High rainfall periods in 1961 and 1962 caused

the head to rise more than 5 feet until April 1962. From April until

sand-and-gravel aquifer in northern Escambia County, and graph of monthly rainfall
 at Pensacola.



September 1962, the artesian pressure head declined about 2 feet be-

cause of below normal rainfall.
 Well 054-726-2 was drilled to a depth of 107 feet and is screened

from 102-107 feet in a permeable sand bed. The water in this bed is not

under artesian pressure, and its upper surface is free to rise and fall. The
water level ranged from 184 to 194 feet above sea level during the period

of record. The water level rose several feet every spring or summer. Be-
