QUALITY ASSESSMENT OF SHALLOW WATER WELLS OR COMMON TOWN ARIQUEMES, RONDONIA, BRAZIL

The use of groundwater must have a rigorous treatment so that they are not sources of disease transmission binding water. Therefore, this study aimed to assess the quality of water from shallow wells or residences of common Ariquemes Rondonia, where it was taken as a basis to divide the city into sub-basins suggested by FUNASA, where they were collected (02 two) samples per sub-basin. We evaluated the following physico-chemical parameters of the water: conductivity, pH, turbidity, color, hardness, consumed oxygen, dissolved oxygen, chloride, ammonia, iron, alkalinity. The results showed that the parameters are in accordance with the decree 518/04 MS (Ministry of Health), except for pH values were lower than suggested. Microbiological parameters of fecal, total coliforms and salmonella were also evaluated, and all had values above the permitted, indicating contamination by pathogenic organisms, thus leaving some concern, since quality of life is directly related to drinking water.
