Avaliação da água utilizada para consumo humano no entorno do cemitério Santa Rosa no município de Laranjal do Jari, amapá

Abstract

Water resources are of utmost importance for the development and survival of human beings, considering their use in a variety of activities. It is observed that some of these activities, such as cemeteries, can put the quality of water at risk, compromising its consumption. The consumption of water contaminated by microorganisms considerably affects human health, causing water-borne diseases that are currently emerging as one of the main public health problems. It should be noted that the waste generated by the decomposition of corpses in cemeteries, known as necrocorume, is responsible for the contamination of groundwater, when it is not installed in compliance with current legislation. In this context, the objective of this study was to analyze the quality of drinking water from an artesian well located in the Mirilândia neighborhood, around the Santa Rosa cemetery, municipality of Laranjal do Jari. As a research method, physical-chemical and microbiological analyzes were carried out at 4 points located around the Santa Rosa cemetery, Laranjal do Jari. The results showed that only the parameters of turbidity and color were outside what was normalized in Ordinance No. 888/2021 of the Ministry of Health, and it was also observed that there is contamination of the groundwater of the Mirilândia neighborhood by coliforms and E. coli, this The result is alarming due to the exposure of the population. It is concluded that the presence of pathogens in the groundwater from an artesian well in the Mirilândia neighborhood may be related to contamination by necroleachate in the Santa Rosa cemetery, being of utmost importance the implementation of monitoring wells within the area to verify the existence of critical contamination points.
