Hydrology
Hydrochemistry is the study of chemical properties and processes that occur in water, including the interactions between water and the surrounding environment. To understanding the chemical composition of water and assess their suitability for drinking and irrigation purpose, water samples were collected of Mbankomo at 10 locations during rainy seasons. From theses samples, anions and cations were separated by high performance liquid chromatography (HPLC) using a Dionex ICS-1100 with 0.45 µm diameter. From de findings, it is clear that surface water has an average pH of 5.63 while, groundwater has an arithmetic mean pH of 5.94, with a range between 5.00 and 6.64. These data indicates that the water remains acidic. From the values of TDS (Total Dissolved Solid) (average value of 26.65 mg/l. in surface water; 27.30 to 118.38 mg/l, in groundwater) water samples in the study area are considered fresh (TDS < 1000 mg/l). Water in the research area acquires mineralization through a variety of natural geochemical processes, such as weathering, dissolution, ion exchange processes, and human activity. WQI (Water Quality Index), based on 14 major parameters indicate that water of study area are good to excellent and can use for drinking, irrigation and industry. The water of study area is suitable for irrigation for almost all types of crops with a possibility of limited sodium hazards.
