The aim of this work was to analyze the physicochemical and microbiological parameters of amazon wells located in the Novo Horizonte, Macapá, AP, which are used for consumption by the local population, aiming to awaken knowledge about water quality and care Inherent to the well, through the application of an educational primer. The sample were collected in drought (November 2016) and rains (March 2017), with water samples stored in 1 liter sterile polyethylene bottles with sealing in 20 amazon wells. The analytical procedures were carried out in loco and in the Laboratory of Organic Chemistry and Biochemistry of the State University of Amapá (UEAP). The analyzed parameters were: pH, turbidity, alkalinity, acidity, total hardness, chlorides, total solids, total and thermotolerant coliforms. All analyzes were performed in duplicate. According to the results, based on the Ordinance of the Ministry of Health No. 2914, of December 12, 2011, which establishes procedures for the control and monitoring of water quality for human consumption and its drinking water standard, it was concluded that the Novo Horizonte neighborhood had a negative index on the groundwater quality used by the local population with the presence of coliforms and, after exploratory analysis of the data by HCA, PCA and boxsplot, the related variations of pH, alkalinity, hardness and chlorides, especially in the rainy season.
