%X The present work deals with the current microbiological status of boreholes found in Zinder region in the Republic of Niger. The study is centered on thirty (30) holes selected to monitor the variation in the microbiological quality of the water. For that the parameters studied are total coliforms, faecal coliforms and E-coli. From these parameters is calculated the microbiological quality index (MQI) by Bovesse and Depelchin method 1980. The variations of the faecal contamination as well as those of the various parameters on the whole of the drillings are represented on maps of spatial distribution. On the whole of the drilling the (MQI), is zero which denotes the absence of any faecal contamination. On 96.67% of the holes is observed the presence of total sprouts with structures having a rate that exceeds 100 CFU per 100 ml of sample. The presence of total coliforms is also observed on 36.67% of the boreholes with structures presenting more than 100 CFU per 100ml of sample. Although these waters do not have faecal contamination, their microbiological quality does not meet the recommended standards for drinking water
