COMPARATIVE STUDY OF SOME PHYSICO-CHEMICAL AND BACTERIOLOGICAL PARAMETERS OF BOREHOLE AND PIPEBORNE WATER IN MINNA METROPOLIS, NIGER STATE, NIGERIA

Physico chemical and bacteriological analyses of boreholes and a pipe-borne water at   Minna metropolis were carried out. Values obtained were averaged for months, seasons, stations and zones. The values were generally low in comparison to set standards by World Health Organization (WHO NSDWQ AND APHA).Temperature was generally above the permissible limits of WHO, NSDWQ AND APHA with mean value ranges from (25.325±0.53 -28.250± 0.27).The pipe borne water sources show higher temperature values when compared with boreholes sources in the study area. More so, BOD indicates a mean value between (0.80 ± 0.77mg/l - 70.10 ± 35.89 mg/l) against 5 mg/L by WHO and NSDWQ, although the peak was attained in Tunga from borehole source. Similarly, COD mean value ranged between (3.00 ± 00mg/l - 175.25 ± 88.97mg/l).The only sample that went above the WHO permissible limit was that of Tunga borehole which was reported close to the dump site.EC, TDS, Turbidity, pH, Total hardness, F, N0₃, DO, Phosphorus, phosphate, mg, ca, Total coli form and E -coli have their mean values below the WHO, APHA, and NSDWQ maximum permissible limits. The study shows that pipe borne water sources is safer for drinking and other domestic uses   when compared with bore holes in Minna metropolis.
