RESUMO
We collected 23 samples of groundwater from residential wells located in the area covered by Barcarena's industrial center (Para), aiming to determine the influence of mining industries on the potability of groundwater used for human consumption. We analyzed the parameters of potability established by Ordinance 518 of 2005 of the Ministry of Health, such as pH, turbidity, chloride, color, hardness, total dissolved solids, nitrite and ammonia. The results showed an average pH of 4.7, an average turbidity of 4.37 UNT, an average chloride of 10.45 mg / l, an average color of 6.18 UC, an average hardness of 12.89 mg / L, and an average nitrite of 47.3 STD. In general terms, all parameters examined were within the standards of potability, except for pH, which is probably associated to the hydrogeological characteristics of the region, showing that water resources are not being altered in quality.
