WATER SUPPLY OP PASTERN AND SOUTHERN PEORIDA. 281 
DADE COUNTY. 
LOCATION AND SURFACE FEATURES. 
Dade County lies in Southern Florida, bordering the Atlantic 
Coast. The county includes an area of 2,305 square miles. The 
western part of the county reaches into the Everglades of Florida. 
East of the Everglades the surface formation is chiefly the Miami 
Oolitic Limestone. 
WATER-BEARING FORMATIONS. 
The limestones exposed at the surface, in Dade County, are 
of Pleistocene age and it is probable that most of the wells 
terminate without passing through these Pleistocene formations. 
The deepest well recorded in Dade County is a well drilled 
recently at Homestead by the Florida East Coast Railway. This 
well reached a depth of 300 feet, but the age of the formation in 
which it terminated was not determined. 
ARTESIAN WELLS. 
The water in the wells at the city waterworks, at Miami, 
rises to within fourteen inches of the surface level and flows into 
the collecting basin excavated for that purpose. The possibility 
of getting flowing artesian water from the Vicksburg Limestone, 
which lies at a depth of several hundred feet, has not been tested 
by deep borings. 
LOCAL DETAILS. 
DANIA. 
A well has been drilled at Dania by the Florida East Coast 
Railway, to a depth of 5,4 feet. The following is an analysis of 
the water from this well made by the American Water Softener 
Company, Philadelphia, Pa., November 3, 1909:
