摘要

Groundwater a crucial freshwater source faces growing contamination risks from land use activities. This study examines the effects of urbanization, agriculture, industrial activity, and landfills on groundwater quality in Muscat, Oman. Wells from varied land use zones were sampled twice a year. The study combines PCA DRASTIC modelling and WQI to assess spatial groundwater quality variations in Muscat, Oman. The data show large variability in groundwater quality across land use. Industrial zone wells show extreme degradation (WQI = 2.02) with hazardous nitrate (70 ppm) and TDS levels. Electrical conductivity ranges from 1.78 to 5.84 mS/cm, and total dissolved solids (TDS) exceed 750 ppm, making water unsuitable for domestic use. Nitrate concentrations range from 24–70 ppm, exceeding permissible limits due to agricultural runoff and wastewater discharge. The majority of wells exhibit low-quality water, with the industrial zone exhibiting the worst degradation (WQI = 2.02). Contamination is indicated by high levels of TDS (> 750 ppm), nitrate (24–70 ppm), and sulfate. High groundwater vulnerability is revealed by the DRASTIC model, and significant disparities among land uses are confirmed by PCA and NMDS. Statistical analyses (PERMANOVA p < 0.0001) confirm land use type drives significant quality differences. This study emphasizes the complex relationship between land use and groundwater quality, as well as the critical importance of sustainable practices. Urgent measures like pollution controls and land-use zoning are needed to safeguard groundwater sustainability. In order to preserve groundwater and guarantee its sustainability for future generations, this study emphasizes the necessity of prudent land management.
