The soil mapping units at the reconnaissance soil survey level demonstrated that these are rather helpful and relatively more homogeneous in the environment stratification for the more geomedical interactions study.

In compiling and interpretative study of the present investigation, the attributes of the soil survey units of the Paraiba (BRAZIL, 1972) are considered favorable or not, in regards to the incidence, prevalence, or frequency of certain diseases, for examples: cardiovascular and cancer. It is, therefore, suggested that the use of these geoenvironmental unutis tied to the diagnostic medical-odontological as a valuable instrument in the epidemiological highlight.
