Abstract: This work was carried out with the objective of assisting in the construction of a water supply system inside Nova Vida Farm, located in the city of Paruapebas, southeast of the state of Pará, Brazil. The farm is divided into areas for the cultivation of various crops, such as corn, beans, and soybeans, as well as in beef cattle breeding, in confinement, export destination. However, in the dry season, with its insipid supply system, consisting of shallow artesian wells and cisterns for water storage. Based on this, a geophysical study of hydrogeological characterization was carried out, using the measurements of two Vertical Electrical Survey (VES) and 6 electromagnetic profiles with the Slingram system using 8 frequencies (110, 220, 440, 880, 1760, 3520, 7040 and 14080 Hz), where the results are presented in the form of graphs for two VES and in isocontours maps for the profiles by locating and identifying the most promising locations for new wells allocation, which can mean the solution for the management of the supply of water the farm.

Abstract: Surface water is one of the most important sources for drinking and agricultural purpose in many parts of the world. The unsuitability of surface water is often caused due to the contamination by inherent toxicity of rocks. Surface water contains many necessary ions like sodium, potassium, calcium, magnesium, chloride, sulphate, bicarbonate and fluoride the concentration of which has considerable effect on surface water quality if exceeding the permissible limits. However, the consumption of water with desirable concentration of ions is good for human health. An assessment of river water quality with special reference to drinking and irrigation purpose was carried.......

Abstract: Single-well pumping test was carried out at constantrateon six hand pump boreholes inpart of Maiha town to give information about the draw down and a quifer characteristics resulting from specific pumping rate .The test was carried out for eight hoursat constantdischargerate for each of the borehole.The drawdown result with respect to time was analyse using Cooper-Jacob'sstraight-line method in ordertoestimatethe transmissivity and specific discharge of the boreholes. The magnitude of the transmissivity in the study area fall within the low magnitude class, which impliesthat the transmission rateofthegroundwaterin the aquifer is low. The boreholes in the study area are of moderate performance which is capable of serving a smaller population using hand pump based on the result of the specific capacity obtained from the result.....
