Assessment of the Efficiency of Disinfection Methods for Improving Water Quality

The efficiencies of three disinfection methods namely boiling, water guard and pur purifier were assessed. The micro-organisms isolated from the groundwater samples were Escherichia coli and E. aerogenes. The major components of Water Guard and Pur Purifier were found to be NaNO2,SO4, Cl2; and NaNO2, Ca, CaCO3, SO4, Mg and ClO2 respectively. Pur purifier was most effective for removal of electrical conductivity, nitrate, total coliform and yeast while Water Guard was most effective for removal of phosphate, potassium, E-Coli and Fungi. In addition, boiling and water guard were most effective for removal of turbidity while boiling was most effective for removal of chlorine. Furthermore, Water Guard was found to be the cheapest with an estimated monthly household cost of N240. Use of Water Guard for disinfecting household groundwater sources utilized for drinking and cooking is highly encouraged among the rural populace to safeguard their health against waterborne diseases.http://dx.doi.org/10.4314/njt.v34i4.33

Evaluation of groundwater quality in a rural community in North Central of Nigeria

Evaluation of water quality of nine boreholes and three open hand-dug wells in a rural community in North Central Nigeria revealed relative abundance of cations Na > k > Ca >Mg> Zn > Pb and anions Cl− > PO4 2 − > SO4 2 − > NO3− in the boreholes and cations Ca>Na>K>Mg>Pb and anions NO3− > PO4 2 − > SO4 2 − > Cl− in the wells. The major contaminants exceeding SON and WHO permissible limits were NO3−, Mg, TH, pH and Mg, Pb, TH, pH and DO in the wells and boreholes, respectively. They are attributable to anthropogenic sources such as domestic waste water and poor waste disposal and natural sources such as mineral dissolution from clayey aquifer which made the acidic groundwater unsuitable for consumption unless they are appropriately treated. Correlation studies revealed existence of three major mineral groups in the aquifer Ca-Fe group, Na-Mg group, Zn-K group, as well as a minor group Pb-group, and they determine the chemical composition of the groundwater and the ionic exchange between the groundwater and mineral-bearing clayey aquifer. In order to curb microbial contamination by Enterobacter aerogenes and Escherichia coli, it is recommended that proper latrines and drainages be provided while domesticated animals should be restricted from boreholes and well. Further, treatment with water guard and pur purifier is recommended
