To evaluate the actual status of water quality and conclude on the mains source of pollution in the Nyong estuary River, seasonal and spatial variation of water quality parameters was interpreted by multivariate statistical techniques (Principal Component analysis). Nine (09) environmental variables were monitored at four surface stations in the estuary for two seasonal cycles. The fieldwork was conducted from 2018 to 2019 during high tide and low tide for each survey. In situ physical parameters were measured for a total of 64 samples (32 samples for each tide). The laboratory works consisted of some physicochemical analyses and processing of these data by descriptive and multidimensional statistical analyses. Temperature, suspended particle matter, nitrate, nitrite and phosphate change significantly in the estuary with season (p < 0.05), while salinity, dissolved oxygen, pH, and ammonium do not vary significantly with season (p > 0.05). Principal Component analysis found temperature, salinity, pH, ammonium to be the most important parameters contributing to the fluctuations of surface water quality in the Nyong estuary during the dry seasons whereas suspended particle matter, nitrate, and phosphate are the most important parameters contributing to the fluctuation of surface water quality in the Nyong estuary during the rainy seasons. Based on spatial variation, the Principal Component analysis found that, sus-

“…Rainfall recharge is considered to be as one of the leading controls on the seasonal uctuation of EC. Recharge reduces the ionic concentration of groundwater whereas leaching, dissolution, and evaporation tend to increase ionic strength in general(Chidambaram et al 2019). The highest TDS is observed in NEM, and lowest values are noted in PRM.…”

The present research reports the level of major ions and other physical parameters like pH, EC and TDS and possible sources of contamination in groundwater from south India. A total of 138 groundwater samples were collected during four different seasons and analyzed for physical parameters and other major ions. Many samples are above or approaching the recommended level of ions for safe drinking water. The groundwater quality has been determined by considering 11 parameters and classified into 5 different categories based upon water quality index (WQI) value. The groundwater of the study area is approaching towards pollution which has to consider for future management of the resource. Different geochemical diagrams like Gibbs and Piper are used to evaluate the process affecting the composition of groundwater. Again, the geostatistical techniques applied to confirm the processes through an integrated approach. Based on result of geochemical investigation, the contamination sources in the groundwater of this region are likely to be from (a) Anthropogenic activities (b) Weathering (c) Agricultural fertilizers. Continuous consumption of such water may pose serious health risk to the residents.
