“…For rural people, the major sources of drinking water are groundwater from boreholes, shallow wells, and springs (Dwairo et al, 2006;NBS, 2010) and are often consumed without treatment which poses a threat to their health (Abatneh et al, 2014). Groundwater alone serves 25 % of human population in arid and semi-arid regions (Jackson et al, 2001;Oki and Kanae, 2006).…”

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.

“…Approximately, 2.2 billion people are without adequate sanitation in the world. In Ethiopia, the majority of people in rural areas and high-density townships in urban areas use pit latrines which are often in a state of disrepair and without hygiene (Abatneh et al 2014;Lungu et al 2008). In the rainy season, fecal matter from pit latrines and open sources is washed into water bodies, thereby contaminating the water (Dzwairo et al 2006).…”

The study was carried out to find the physicochemical water quality of borehole and spring water supplied to Robe Town. For this study, a total of six water samples were collected from three borehole and three spring water sources. The analyses for 14 physico-chemical parameters, pH, turbidity, electrical conductivity, total dissolved solids, total suspended solids total hardness cations (Ca 2? , Mg 2? ), anions (NO 2 -, NO 3 -, SO 4 2-and PO 4 3-) and heavy metals (Fe and Mn), were done in the laboratory by adopting standard procedures suggested by the American Public Health Association (APHA). Descriptive statistics were used to describe data, while Pearson correlation was used to determine the influences of the physico-chemical variables. The single factor analysis of variance (t test) was used to determine possible differences between the borehole and spring water, while means plots were used for further structure detection. From the total samples analyzed, most of the samples comply with the water quality guidelines of Ethiopian limit, WHO and U.SEPA. The pH of the water samples from borehole groundwater source was found to be slightly acidic and bove the maximum permissible limit (MPL). High concentration of Fe and Mn that exceeds the MPL set by WHO was found in the three boreholes. The spring water sources were found to be better for drinking than borehole water sources.

More than 2.1 billion people worldwide are deprived of safe drinking water at homes. The situation is strikingly worse in a developing country like Pakistan where over 69% of the population does not have access to safe drinking water. The present study evaluated a perenial herb, Typha angustata (TA), to purify the spring water. For this purpose, 25 water samples were collected. Majority of samples (20/25) were highly contaminated with microbes ranging colony forming units (CFU) per millileter per Petri dish ranged from 85 to 279 with an average of 136.4. Microbial inhibition of water samples treated with the nonmodified plant extract was observed to be better with the average of 55.5% compared to the treatment with NaOH chemically modified plant where average 46.4% inhibition of microbial load was observed. Four species of microbes such as Bacillus cereus, Pseudomonas aeruginosa, Pseudomonas otitidis, and Streptococcus agalactiae were identified after sequencing. We concluded that T. angustata extract may be used as an antibacterial agent/biosorbent for the purification of drinking water to provide safe drinking water to billions of humans. Practitioner points Spring water samples were collected from 25 different springs. Spring water samples were analyzed for physiochemical parameters. Spring water samples were found to be contaminated with pathogenic bacteria, that is, Bacillus cereus, Pseudomonas aeruginosa, Pseudomonas otitidis, and Streptococcus agalactiae. Pathogenic bacteria in spring water samples were treated with extract of Typha angustata. Extract of Typha angustata was found as a potential antibacterial agent against pathogenic bacteria.
