The northeastern semi-arid region presents climatic and geomorphological irregularities besides low rainfall, indicating low volumes in its sources. The present work has the objective of showing a qualitative diagnosis of environmental conflicts and the use of water in the county of Monteiro, located in the microregion of Western Cariri of Paraíba, in the high Paraíba River course region. The research was carried out between the years 2014 and 2016, being highlighted the physical and socioenvironmental aspects for identification of the agricultural/agropastoral activities and the contamination of river waters by agrochemicals and household wastes. The agropastoral and agricultural activities in the highlighted years contributed in some way to observing the use of polluting materials, leading to the contamination of the existing water reserves in the region. The conflicts, of anthropic activities, extended more between the East axis where the levels of pollutants totaled an area of 16.1 km in relation to the South axis of the Paraiba River, in 2014. On the other hand, in 2016 the conflicting area had an increase of 22.5 km, close to the Poções reservoir, superficial water source of the region, which is included in the São Francisco River Integration Project, thus increasing the level of contaminations and loss of vegetation.
