A Comparative Study of Water Quality Between Hot Spring and Borehole Waters of Mara, Shinyanga and Manyara Regions of Tanzania
This study conducted for the comparison of physico-chemical parameters between hot springs and borehole waters. Fourteen samples were collected at Mara, Shinyanga and Manyara in Tanzania. Multimeter used for the analysis of physical parameters pH, EC, TDS, salinity and turbidity. Titrimetric methods were used for the determination of Cl-, total hardness, Ca2+ and Mg2+. UV-Vis. Spectrophotometric method for NO3-, SO42-, F-, Fe2+ and Mn2+ and Flame Atomic Absorption Spectrometer for Cd2+, Zn2+, Ni2+, Cu2+ and K+. The EC, TDS, salinity, turbidity, Cl-, NO3-, SO42-, F-, Mn2+ and Cu2+ are higher (pH = 7.44-9.42, EC = 4251.33-15334 µS/cm, TDS = 2079-7526.7 mg/L, salinity = 2.2-8.67 ppt, Cl- = 189.3-3577.6 mg/L, SO42- = 11.83-1353.33 mg/L, F- = 4.68-18 mg/L, Mn2+ = 1.03-2.0 mg/L, Cd2+ = 0.01-0.05 mg/L, Cu2+ = 0.37-0.93 mg/L and K+ = 44-100 mg/L) in hot springs than borehole waters (pH = 6.36-6.58, EC = 270.0-2674.64 µS/cm, TDS = 123.67-1305 mg/L, salinity = 0.03-1.37 ppt, Cl- = 6.25-659.93 mg/L, SO42- = 28.92-493.33 mg/L, F- = 0.89-3.0 mg/L, Mn2+ = 0.3-1.70 mg/L Cd2+ = 0 mg/L, Cu2+ = 0.49-0.64 mg/L and K+ = 16-52 mg/L). The t-test at the probability 0.05 showed that there is significant difference of the parameters pH and Ni2+ between hot spring and borehole waters. Some of the parameters are at higher levels than permissible values for both hot spring and borehole waters. Therefore, there is a need of treatment for these waters before using for domestic purpose.
