Análise da gestão de águas subterrâneas em Mato Grosso

Abstract

Groundwater is a natural resource of vital importance for the supply of potable water in rural and urban areas, for use in economic activities, and for the maintenance of aquatic and terrestrial ecosystems. The degradation of the quality of surface waters and the development of drilling techniques, which make access to groundwater easier and cheaper, have led to an increase in its use for various purposes. This work aims to investigate how groundwater management occurs in Mato Grosso according to the National and State Water Resource Policies and sublegal norms, and how management instruments are being adopted for groundwater. The methodology includes a documentary bibliographic review, based on initial qualitative research in official databases. Relevant legislation and how groundwater is addressed in water resource plans and information systems (availability of quantitative and qualitative data) were evaluated, as well as in the State Water Resources Council, from which meeting minutes and published resolutions were assessed. The results highlight advances in legislation for groundwater, but underscore persistent challenges, such as inadequate integration with policies for surface waters and deficiencies in monitoring. It is concluded that it is crucial to strengthen governance, increase transparency and public participation, and improve hydrogeological studies to support effective decisions and preserve this vital resource.
