Abstract

This work aimed to inspect the microbiological quality of water from a well located in the monkey site in the rural area of Areia-PB. The study was developed with water samples collected in an artesian well located at the monkey site in Areia-PB. The water samples intended for microbiological analysis were collected directly from the artesian well, in wide-mouth glass bottles (500 ml), protected with laminated paper, previously autoclaved at 121 oC for 30 minutes, and were sent to the Laboratory of the Vocational Training Center of the Albano Franco Institute of Leather and Footwear Technology (CTCC) in Campina Grande. The samples were stored at 4 to 8 oC for a maximum of four hours until sowing. The parameters analyzed were: total coliforms, thermotolerant coliforms, Escherichia coli and heterotrophic bacteria. The microbiological parameters of the waters were determined following the methodologies of CETESB. Based on the potability criterion established by the Ministry of Health Consolidation Ordinance No. 5/2017, it was observed that the samples analyzed presented an amount of heterotrophic bacteria, totally outside the limits established by the current ordinance (up to 500 CFU mL-1). Regarding total coliforms and thermotolerant coliforms, the samples showed positive results. The presence of E. coli bacteria was not evidenced. It is concluded that all samples are in disagreement with the recommendations stipulated by the current Ordinance, thus requiring significant improvements regarding source protection, sewage disposal and pre-treatment before being supplied for human consumption.
