This dissertation reports on a comparison of the physico-chemical parameters
between hot springs and borehole waters. Thirty four samples were collected at
Mara, Shinyanga, Singida, Manyara and Dodoma in Tanzania. Multimeter used for
the analysis of physical parameters pH, EC, TDS, salinity and turbidity.
Titrimetricmethods were used for chemical parametersCl−, total hardness, Ca2+ and
Mg2+. UV-Visspectrophotometricfor NO3

1.70 mg/L and Cu2+=0.27-0.64 mg/L). Other parameterstotal hardness, Ca2+, Mg2+
Fe2+ and Ni2+ are higher in borehole waters than hot springs. Thet-test (p=0.05)
showed that there is significant difference of the parameters pH, EC, salinity, TDS,
F− 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
