Abstract

Research effort dealing with the remediation of leaching waters
polluted to prevent further damage of surface and ground water reserves are
needed. For this purpose, diatomaceous earth, an inexpensive, available and no
pollutant material, has been tested for retention of persistent pollutants, such as
heavy metals (cadmium) and pesticides (atrazina and chlorpirifos). It has been
used as underground water pollution prevention because of their high mobility
reported, and for cleaning irrigation waters of a soil destined to agriculture
purposes. There are parameters, such as depth, thickness, etc. that should be
carefully established in order to respect the exploitation use of the potential polluted
soil. The results obtained shown percentages retention for cadmium higher
than 75 %, and 50 % for atrazina. This emphasises the potential of diatomaceous
earth with remediation and cleaning purposes for persistent pollutants, such as
heavy metals and pesticides used for this purpose. This DE adsorption is valid for
all soils tested. The possibility to prevent cadmium underground water pollution
by placing a diatomite earth layer under the surface of the soils exists then.
