South Dade County, Florida, is one of the few areas in the continental United States where winter fruits and vegetables are grown. About 85% of the agricultural area is underlain by Rockdale soil composed of crushed limestone and organic debris. The remainder of the agricultural area is underlain by Perrine marl. Both soils must be irrigated and require frequent applications of fertilizer, micronutrients, and pesticides. The agricultural area overlies permeable limestone of the unconfined Biscayne aquifer, which is designated as the sole source of drinking water for southeast Florida. The unsaturated zone in the agricultural area ranges in thickness from 0.3 to 4.6 m.

Geochemical Techniques for Identifying Sources of Ground-Water Salinization offers a comprehensive look at the threat to the United States' freshwater resources due to salinization and outlines techniques that can be used to study the problem. The book reviews the seven major salt-water sources that commonly mix and deteriorate our fresh ground water (natural saline ground water, halite solution, sea-water intrusion, oil- and gas-field brines, agriculture effluents, saline seep, and road salting). Other topics covered are the characteristics of saltwater sources, geochemical parameters, and basic graphical and statistical methods that are frequently used in saltwater studies. The book also provides geographical charts showing the distribution of the major salt-water sources, illustrating which ones are potential sources in any given area in the United States.Geochemical Techniques for Identifying Sources of Ground-Water Salinization describes the individual geochemical parameters used in identifying salinization and the information on how and where to obtain them. This is an informative book for anyone interested in the present and future quality of our fresh-water supply.
