Avaliação da qualidade da água potável que abastece as residências do bairro Pitimbu, Natal-RN

Abstract

Drinking water can present risks to human health if it does not receive adequate treatment to reach the required quality. Thus, the present work aimed to evaluate the water quality in the Pitimbu neighborhood of the city of Natal, verifying its adequacy to potability standards. Water samples were collected from the public supply network and from the domestic reservoir, in ten residences. The following parameters were analyzed: pH, electrical conductivity, turbidity, free residual chlorine and Total Coliforms. The results obtained indicate non-conformity in pH in 90% of the samples from the public supply network and in the concentration of free residual chlorine in two samples from residential reservoirs, the other physical-chemical parameters and the microbiological parameter complied with current legislation.
