Qualidade da água de poços tubulares localizados no Município de Monteiro PB.

Abstract

Consumption of water from alternative sources, mainly through tubular wells, has been an increasing practice, especially in the semi-arid region of Northeast Brazil, due to the scarcity of good quality water in the surface water sources and the periods of drought and scarcity element. This work aims to evaluate the groundwater quality of five tubular wells, located in the urban area of Monteiro-PB, used by the population for domestic use. Wells were evaluated from the extreme places of the city, ranging from the periphery to the center of the city. The water samples were collected in November and December 2017 and in March 2018. Laboratory, physical, chemical and microbiological parameters characterizing the quality of the resource were used as support. The results obtained were compared to the potability standards issued by Ordinance No. 2914 of 2011 of the Ministry of Health and revealed that the water samples were not, in most cases, in accordance with the potability levels of the physico-chemical parameters and necessary for water to be considered potable and can be consumed by the population. These results also revealed the need for effective basic sanitation, ranging from an efficient sewage network to a complete collection of waste, as a way to reduce pollution and prevent diseases that may be caused by poor water quality.
