  • Evaluation of groundwater and surface water availability

The assessment of water availability is of paramount importance to enterprises, in general, once the water has become an increasingly coveted resource and, at the same time, more protected. In a study of water availability, surface and groundwater resources available to enterprises are assessed in terms of the allowed maximum intake flow, taking into consideration flows committed to users already established. Important consideration is given to possible environmental and heritage constraints, thus facilitating grants and permits deferral. The ultimate goal of a study of water availability is to indicate, to the entrepreneur, sustainable source alternatives for raw water for its industrial consumption


  • Raw water intake (study of locational alternatives)

Within the assessment of water availability, the study of locational alternatives for raw water intake aims at a cost-effective assessment to indicate which alternative is more beneficial to the enterprise.


  • Hydrochemical characterization of water bodies

The hydrochemical characterization of water bodies has the objectives of checking the conditions of usability of water abstracted for industrial processes and to verify the conditions of water quality in the release of effluent, before usage Classes, according to CONAMA Resolutions 357/2005 and 396/2008.


  • Hydrogeological inventory of springs and drainages

The hydrogeological inventory of springs and drainages is one of the first steps in hydrogeological characterization of a region where enterprises are to be set, when their activities affect water resources. During this activity, the main water sources are registered and all the major drainages are covered, with an aim at understanding how discharge of groundwater are processed in these sub-basins. Wells, ponds and tanks are also registered. Expeditious measurements of flow and physical-chemical parameters are made in situ.


  • Hydrogeological conceptual models for Pre-Feasibility Report and Statement of Environmental Impact Assessment

In many enterprises, either the Environmental Impact Assessment (EIA) or the Pre-Feasibility studies already require an understanding, at a conceptual level, of the hydrogeological environment where they are located. In a hydrogeological conceptual model, the main characteristics of the aquifer systems are presented, as well as their relationship with surface water, with the climate regime, and with relief. In mining, specifically, preliminary estimates of the groundwater inflow to the mine are made (open pit or underground mine) as well as the prediction on the impact on local drainages.


  • Hydrogeological numerical models

Hydrogeological numerical models are useful tools for better understanding of subsurface hydrodynamics in various studies such as: lowering of water table in mining areas or for relief of foundations; dispersion of contaminants in groundwater; and water wells projects. Hydrogeological numerical models allow simulating a number of scenarios and testing various hypotheses about the hydrogeological framework of the project in question.


  • Aquifer tests design and oversight

Water drawdown tests in wells are designed to extract quantitative information about the hydrodynamic parameters of a given hydrogeological system (hydraulic conductivity, specific storage, specific yield, among others). In order for these parameters be used reliably in future studies, it is essential that the test is designed specifically for the case at hand and executed correctly, monitored by a qualified professional.


  • Design for lowering of groundwater level in mines and pits dewatering

Very often in mining, lowering of the water table is either a necessity or a consequence of mine operation. In such cases, a detailed hydrogeological study, usually supported by a computational model, is crucial to the dewatering system design. In these projects, the means for aquifer drainage are defined as well as the location of draining devices and optimal exploitation rates over time.


  • Development of programs for hydrological/hydrogeological monitoring

The establishment of a monitoring program hydrological/hydrogeological monitoring is important for better understanding of the interrelationship between groundwater and surface water in a given hydrogeological context. For enterprises in pre-operation phase, this program is able to establish conditions for the "background", an important step for the company to plan its water resources policy and its status in relation to other stakeholders. In other cases, conducting a monitoring program is part of conditions of environmental permits or permits for water use.


  • Consistency analysis of monitoring data and results interpretation

Data obtained from a monitoring program must be processed to check its consistency and to correct any errors that may appear. Once consisted, data interpretation aims at the establishment of flow regimes and understanding of their correlations with other hydrogeological and hydrological variables producing basic subsidies to the hydrogeological conceptual and numerical models.


  • Project and installation oversight of monitoring devices (piezometers, weirs, sampling wells)

For monitoring programs to successfully reach their goals, it is necessary that the monitoring devices are designed to suit the specifics of each situation. Thus, the careful design of monitoring devices aims not only to the quality of the data obtained, but also the accessibility and the longevity of its use.


  • Characterization and diagnosis of 'background' (pre-operation) and contaminated areas

Environmental issues are extremely sensitive to companies, since they affect how their image is perceived by their customers and by the market. Thus, in the pre-operation phase, the diagnosis of 'background' aims at characterizing the project area, supporting the entrepreneur with the knowledge of any pre-existing environmental liabilities as well as in its environmental policies.


  • Water balance for dams reservoirs and projects

Dam reservoirs (either for exclusive uptake of raw water or for tailings disposal) are crucial to the understanding of water availability in an enterprise. Thus, the development of a water balance seeks to understand, statistically, the dynamics of in-flows and out-flows in these reservoirs, so that the entrepreneur can make decisions regarding water management and its industrial effluents. The water balance is also an important tool for the entrepreneur can manage the quality standards of their effluents into water bodies.


  • Studies of acid drainage formation in rock piles and tailings dams

Acid drainage is a phenomenon that usually occurs when sulfide materials are exposed to weathering (in waste piles or in tailings dams). When this occurs, acid drainage can bring very serious consequences, such as contamination of soil and water by heavy metals. Understanding what materials have this potential and knowing what steps to take to prevent or control the generation of acid drainage is essential for mining enterprises to minimize their environmental liabilities and achieve greater agility in obtaining environmental permits.

  • Grants for surface- and ground-water

The use of surface water and / or groundwater is only awarded to the entrepreneur, after obtaining a grant, the legal instrument which gives the user the right to use those resources. Application for a grant requires hydrologic and / or hydrogeological studies to support the calculation of the grantable flow at a given site, which later will be part of the Technical Report for Grant Request.
