The existence of surface water is not always sufficient for the needs of the community, also for agricultural needs. Therefore, groundwater can be an alternative water supply in the irrigation system, so it is necessary to assess its quality. Groundwater quality is the result of the interaction of material (soil/rock), the type of flow/transport and the change processes. The results of these components produce different groundwater quality in each region. To assess the groundwater quality in Bener and its surrounding areas, this research was carried out by direct survey in the field and testing the physical/chemical properties of groundwater in the laboratory. Groundwater sampling was carried out at 6 dug wells and 2 springs. The analysis shows that all samples are bicarbonate groundwater types, with variations of Na+, Ca2+ and Mg2+ dominant cations. Groundwater quality shows a pH value of 6.2 - 6.7, TDS of 45 - 306 ppm, hardness of 39.73 - 200.43 ppm, SAR (Sodium Adsorption Ratio) of 12.12 - 76.64, Na% of 19.81 - 62.11, and RSC (Residual Sodium Carbonate) of 0.04 - 1.35. According to its quality, groundwater can be used to support irrigation for agriculture in the area.
The Galur and Lendah areas are in the southeastern part of Kulon Progo Regency, Yogyakarta, Indonesia. This area has become a developing area because of the new airport in this district. Along with its development, the need for groundwater in this area is increasing, so groundwater research is also increasingly needed. A study on groundwater is required to support the development of this region. This time, a groundwater study was conducted to determine the potential for the recharge-discharge zone, also groundwater flow patterns based on the chemical facies of the groundwater. The hydrogeological survey was carried out with groundwater sampling from 9 (nine) dug wells and 1 () spring for physical/chemical testing of groundwater in the laboratory. The results showed groundwater in the study area generally flows south or northwest, with a radial pattern anomaly in the north. The shallow groundwater studied was bicarbonate type with Ca, Na, and Mg cations variations. The groundwater facies characterizes groundwater that is typical in the catchment
This research is a hydrogeological survey activity with the aim to determine the geological characteristics of groundwater in the Hargorejo area, Kokap Sub-district, West Progo. The study wants to know about the pattern of groundwater flow and water quality in the area. The northern part of the research area is included in the non-groundwater basin region of the West Progo Dome, while the southern part is included in Wates Groundwater Basin. Method of research is a field hydrogeological survey, to obtain geological and groundwater data. Groundwater flow pattern and quality analyses are based on groundwater data and pH, TDS and EC values. Groundwater can be obtained from springs or dug wells, with relatively shallow groundwater tables. The pattern of groundwater flow is generally to the south, with the H4 / H5 basin boundary type. Groundwater quality is quite good, with a pH value of 6.2 -7; TDS 191 - 558 ppm, and EC ranges from 279-783 µS / cm.
