“…Monitored seasonal geochemical variations and the water quality of groundwater in the aquiferous formations of Kumba [14] and [15]. The saturated hydraulic conductivities of aquifers in Kumba were studied in 2016 [16] and darcy and apparent velocities of groundwater [17]. Their studies were based on water quality and how time taken for contaminants to enter or leave the aquifer.…”

The rapid economic growth of the town present the matter of water issue as a problem to human life human life, construction life, agriculture, etc. This study is to predict techniques of foundation construction through the displaying of the water table at the flow direction in the town of Kumba and GIS. It is characterized by a significant research question which is the level of fall and rise in groundwater levels within the town of Kumba and this influence on choice of types of foundation in construction. This study is directed to decision makers, and technicians of the construction field to develop policies facilitating the supervision when building construction foundation by informing about water level depth and its flow direction in the town. To achieve this, depths of static water levels were measured in over 200 randomly selected hand-dug wells in Kumba, after their geolocation and data were collected during the dry season (November and March 2017) and during the rainy season (between April and October 2017). Data were analyzed and treated using Microsoft Excel and GIS software us as Golden Surfer, Global Mapper, and ArcGIS. The results show variations of water level and those areas that may threaten foundation construction. Quarter as Kumba Station, Mile 1, Bulletin Street (Fongong Quarter), and parts of Fiango show that water table is to deep water and proper for the shallow foundation but very hard

“…Groundwater pollution is particularly significant in rural areas of developing countries, such as Cameroon [4]. Various studies have utilized diverse analytical methods to assess critical water quality conditions in different regions of Cameroon [5,4,71,72] The geological conditions, recharging water and the extent of water rock interaction influences groundwater quality rock [22,31,12; 30,8].…”

This research focuses primarily on exploring the role of silica in deciphering the geological controls and hydrogeochemical processes affecting groundwater in this challenging terrain. To assess the hydrochemical properties of groundwater and its quality, fifty samples were collected from hand dug wells, boreholes, springs and rivers. Electrical conductivity (EC), pH, temperature and total dissolved solids (TDS) were measured in situ. The mean concentration of major ions indicated Ca > Mg2+ > k+ > Na+ and HCO-3 > CL- > NO-3 > SO2-4. The majority of the water samples (76%) were found in the rock dominance zone, while only 14% were in the precipitation dominance zone, indicating that the interaction between rock and water is the main factor controlling the groundwater chemistry. Chemical geothermometry was used to estimate the groundwater temperature .The silica levels in the samples ranged from 5.8 to 58.7 mg/l, and chalcedony temperatures of over 60°C were detected at five sites, indicating a depth of over 1,000 metres. This study highlights the effectiveness of this combination of instruments in tracking water-rock interactions, regardless of factors such as flow depth, water properties, geological conditions and variations in interaction time. Examination of mineral saturation indices showed supersaturation with silicate minerals such as quartz, but undersaturated with carbonate, sulphate and halide minerals such as calcite, gypsum and anhydrite.

The physicochemical properties and impacts on water quality were evaluated in volcanic and sedimentary aquifer systems for management and sustainable development. Fifty (50) water samples were collected from hand dug wells, boreholes springs and rivers. The physicochemical parameters (pH, EC, TDS, T, and Salinity) were measured in situ. The pH ranged from 6.22 to 6.68 with a mean of 6.49 signifying slightly acidic. Slightly mineralized water sources with TDS that ranged from 11 to 211 mg / l. The mean concentration of the major ions indicated Ca2+ >Mg2+ > Na+ > k+ and HCO3− >CL− >NO3− >SO42− The hydrochemical facies were Ca-Cl type (74%), Ca-HCO3 type (20%), and mixed Ca-Mg-Cl (6%). The Gibbs plots indicated 86% dominance of rock weathering influencing the chemistry of the water sources, 14% by precipitation and cation-exchange as indicated by positive CAI values. Twenty-nine (58%) samples were classified as excellent water quality (Rank I) according to the Drinking Water Quality Index (DWQI). At the same time, 13 (26%) samples had drinking water of good quality (rank II). In the research area, the distribution of groundwater physicochemical indicators and drinking water quality index (DWQI) was shown. According to the Wilcox diagram connecting sodium percentage with total concentration, all of the samples fell in the good to permissible for irrigation. Based on Residual Sodium Carbonate (RSC) and Soluble Sodium Percentage (SSP), the results indicated that the majority of the groundwater samples were suitable for irrigation.
