Bacteria in Sand - Beachapedia

Could the sand be acting as a "reservoir" for bacteria and therefore a source of bacteria found in the ocean? Trying to answer this question has led to studies that measure indicator bacteria in beach sand. Conventional wisdom has been that fecal indicator bacteria such as enterococcus and E. coli do not survive for very long in the environment once they are disassociated from a human or ...

Characteristics of Tropical Soils | Sciencing

The kaolinite (clay) soil that is commonly found in tropical regions has very good drainage. Due to the large micelles (phospholipid compartments within the soil) that are tightly bound together, the clay in tropical regions does not expand with the absorption of water. The soils of temperate regions that contain clay also often contain the element montmorillinite. This material absorbs water ...
