摘要：Civil construction has grown inadvertently in Brazil, and, consequently, its demands for raw material. The production of such materials, as to any industrial process, yields wastewater effluents and has as destination, in general, water resources such as rivers and lakes. Nonetheless, government inspection cannot keep up with the number of starting companies, resulting in impunity due to lack of inspection. In the present work, the first of the kind, some chemical-physics aspects of wastewater effluents samples generated from grout industries were analyzed. The study shows that the pH of these samples lie outside the established limit by the national laws. The extremely alkaline pH and high conductivity of these effluents may cause severe damage to the aquatic environment in which they are disposed.
