The aim of present study is to evaluate the groundwater quality of Liaquatabad Town using water quality index (WQI) measured through physico-chemical parameters. For this purpose, groundwater samples (n = 31) were randomly collected through boring wells from various sites of study area. Data revealed that TDS content of groundwater is very high (mean: 1045.55 mg/L) which is double the WHO limit for drinking purpose. Elevated concentration of Ca, Na, Cl, and HCO3 is reported in 85%, 33%, 40% and 70% wells respectively which are exceeding the corresponding WHO guideline for drinking purpose. Very high concentration of these major ions (Ca, Na, Cl, and HCO3) is indicative of sewage mixing with groundwater in Liaquatabad. The calculated value of water quality index (WQI = 66.1) shows that groundwater in Liaquatabad town is not suitable for drinking purpose but can be used for industrial and irrigation purpose. © International Journal of Ground Sediment & Water, @ Sun Jichao.

The author relies on the "Aojiang River Basin decorative stone centralized mining area UAV aerial image interpretation" project, obtained by aerial image interpretation of the Aojiang River basin in Fujian Province decorative stone geological evaluation of environmental indicators of the basic data. On this basis, it is put forward that it is suitable to evaluate the geology environment of facing stone mine by adopting the grid method and analytic hierarchy process. The geological environment evaluation of facing stone mine based on the grid method and AHP was studied, and the geological environment evaluation index of the mining face stone mining in Aojiang River Basin was collected. According to ARCGIS platform, the index assignment is converted into the corresponding raster data, and then the contrast matrix is calculated to calculate the index weight, and the raster data is used to calculate the comprehensive evaluation of the geological environment in the study area. Finally, the grading map of the geological environment assessment in the study area is obtained. Thus providing basic data and decision-making basis for eco-environmental protection in Aojiang River Basin and accumulating experience for the evaluation of mine geological environment in the province. © International Journal of Ground Sediment & Water, @ Sun Jichao.
