The increasing rate in population, poor sanitation habits, flooding and lack of enforcement of environmental Sanitation laws in the study area have contributed immensely to the pollution of water sources. Thus, water samples were obtained from river Niger, hand-dug wells and a bore-hole in Ganaja, Lokoja, north-central, Nigeria for water quality analyses. The hydro-geochemical results showed that the pH values range from 6.70-7.70 indicating alkaline water type. The water hardness of the hand dug wells rage from 7.46 - 241.09 with an average value of 110.30 indicating soft to moderately hard water. The hardness value of sample (HW-S8 = 53mg/l, HW-S9 = 241.09 mg/l, HW-SW10 = 152.87mg/l, HW-S11 = 207.78mg/l, HW-S12 = 155.67, HW-S14 =152.03mg/l, HW-S15 = 150.11mg/l) and the TDS for sample (BH-S1) is 525mg/l, the concentrations of K in HW-SW10 = 13mg/l and Ca in HW-S11= 79.89mg/l. These are all above the WHO admissive limit. The value of the physico-chemical parameters such as the ToC, Ec, BOD, COD, HCO3, CO3, SO4 Cl, NO3 Na, Ca Mg, and the heavy metals including Pb, Cd, Cu, Fe, Mn, Ni and Zn as well as the concentration of TDS, Ca and K in all other waters samples are within the allowable limits. TDS is linked to taste, hardness, corrosion properties and tendency for incrustation by water. Negative association between water hardness and cardiovascular disease have been observe. Hard water can cause aesthetic problems. An increase K in the blood is known as hyperkalemia appears as reduced renal functions, abnormal breakdown of protein and severe infections. It is advisable that the water be treated against hardness, TDS, Ca and K before consumption or other domestic use..
