%X O trabalho tem como objetivo estudar a contamina  o microbiol¨®gica do perfil do solo com esgoto sanit¨¢rio sob tratamento pr¨¦vio. O experimento foi montado no delineamento em blocos casualizados (DBC) com tr¨ºs repeti  es. Os seguintes tratamentos foram usados: T - solo sem irriga  o; MC - solo com aplica  o de ¨¢gua doce e MR - solo com 350 aplica  es de ¨¢gua residu¨¢ria. Foram coletadas amostras de solo, um dia ap¨®s a ¨²ltima aplica  o do efluente para an¨¢lise microbiol¨®gica. Os resultados comprovaram que no MR a contamina  o por coliformes termotolerantes na superf¨ªcie do solo foi m¨ªnima esem risco para a sa¨²de do homem, chegando ¨¤ aus¨ºncia de contamina  o a 1,00 m de profundidade. The microbiological contamination of soil by pretreated domestic sewage was analyzed. An experiment featuring randomized block design (RBD) with three replicates was undertaken. The treatments comprised: T ¨C non-irrigated soil; MC - soil with fresh water; MR - soil with 350applications of wastewater. Soil samples were collected one day after the last effluent application of effluent so that microbiological analysis would be undertaken. Results show that the contamination of soil surface by fecal coliforms in the case of MR was minimum and without any risk to health human. Absence of contamination was reported up to 1,00 m depth.
