Analysis of water quality intended for human consumption in a rural community in the Coxim/MS municipality

Abstract

The use of groundwater for human consumption has been widely used mainly among rural populations and communities. Groundwater is linked to quality in relation to public health and environmental issues. The quality of the water is not always visible to the eyes so periodic laboratory analyzes are necessary to better classify them and check their potability for consumption. Water is classified as potable when the test values are within permitted limits. This study aimed to evaluate the physicochemical and microbiological quality of an artesian well used in a rural community in Coxim (Mato Grosso do Sul) for human consumption. The study also analyzed the Natural Groundwater Quality Index (IQNAS) which was built on the similarity to the National Sanitation Foundation Water Quality Index (adapted by CETESB) and also analyzed the Aquifer Vulnerability using the developed GOD methodology. by FOSTER & HIRATA (1988) which consists in planning three physical parameters and thus generating a natural vulnerability index. From the analyzed parameters the results indicate that only total coliforms present values above the three allowed by law, and should be investigated, as it may be a natural characteristic of water, and may have been contaminated during the well construction phase or some transmission in the water zone. recharge and the results of the Groundwater Quality Index (IQNAS) presented optimal conditions and the estimation of Aquifer Vulnerability negligible conditions.
