Exploitation of mineral aggregates as sedimentary type has a great expansion at national level and at the level of the Alba Iulia County; due to growing industrialization thus aggregate resources are critical to modern society. Aggregated resources are used in almost every element of the newly built environment, whether for roads, bridges and transportation infrastructure, either for private development. Natural aggregate (crushed stone, sand, and gravel) is used as a construction material in various sectors, especially in this period, when, in Alba County, are developing a series of infrastructure projects, such as the construction of highways and railways. Sand and gravel pits are located in almost every city of Alba County, especially on the terrace of the rivers Mures, Tarnava and Sebes. In this period the demand for aggregate will continue to grow, due to the increasing number of infrastructure projects in the coming years. Investments in transport infrastructure that were started in the city of Sebes require a large amounts of mineral aggregates, therefore deemed appropriate location of that exploitation of mineral aggregates in the locality Lancram, area rich in resources, in order to secure the raw materials necessary, but also to reduce their transport costs from other areas. The present work want to be a study conducted for the identification and quantification of soil and groundwater impacts generated by the exploitation of mineral aggregates from the upper terrace of the rivers Mures in Sebes municipality area.
