Drinking water quantity and quality is of the utmost importance. If the drinking water gets contaminated, it can result in severe health problems. For example, the continuous consumption of drinking water containing more than permissible amounts of fluoride can lead to bone deterioration and increased risk of bone fracture [1]. The present study was carried out to check the quality of underground water of Sukkur city. The analyzed parameters were fluoride, sodium, magnesium, calcium, potassium, iron, arsenic, TDS, pH, conductivity, odor, color and taste. World Health Organization (WHO) standards were followed in present study. Underground water samples were collected from 20 different populated locations of Sukkur city. Only arsenic, pH, iron and potassium were found to be within health safe limits while the rest of the parameters exceeded the permissible standards set out by WHO. The TDS, sodium, fluoride and magnesium were over the limits at some locations.

Physicochemical and bacteriological analysis of underground water of Crush Rock mining pit in Ishiagu, Ebonyi State Nigeria were carried out to determined the pollution level and the potability of the groundwater due to mining and human activities. The results were compared with standards for water pollution and World Health Organization for drinking water. The results showed that total dissolved solids (TDS), total alkalinity, calcium and sodium, which had concentration ranges of 126-986ppm, 200.18-615.55ppm, 7.8- 30.10ppm and 64-88ppm respectively, were above standards. However, the mean concentration of dissolved oxygen (DO)(1.2-3.20ppm) was below the standard. Other parameters measured were found to be within the permissible acceptable standard. Pseudomonas, Chromobacterium, Bacillus, Escherichia, Staphylococcus, Flavobacterium, Micrococcus, Citrobacter and Achromobacter species were identified as the major bacteria isolated from the underground water. The study revealed that the underground water from Crush Rock mining pit in Ishiagu Ebonyi State, Nigeria require some chemical and physical treatment as it is unsafe for human consumption.

This study examined the mycological quality of groundwater in Yenagoa metropolis, Bayelsa State, Nigeria. Triplicate water samples were obtained from 8 locations in the metropolis, and the fungi quality analyzed following standard microbiological procedures. Results showed that total fungi density ranged from 5.2±1.00 x102 to 8.50±0.56 x103 CFU/ml. Analysis of variance indicates statistical variation (p=0.001) across locations with total fungi density exceeding the limit of 102 CFU/ml specified by World Health Organization/Food and Agricultural Organization for potable water in 62.50% of samples. Eight fungi isolates (species) were identified in the study with frequency across the locations as follows: Aspergillus flavus (20.59%), Aspergillus fumigatus (20.59%), Aspergillus niger (20.59%), Cladosporum (5.88%), Fusarium (2.94%), Mucor (8.82%), Penicilium (14.71%) and Rhizopus (5.88%). Of these, Aspergillus species were predominant across the locations. Since groundwater meets diverse purposes, it is essential that it is suitable for the desired use, and this can be done using appropriate technology to make groundwater potable for human consumption.

ABSTRACTFluoride levels in drinking water exceeding 1.5 mg/L especially underground water can be detrimental to health. Various defluoridation technologies exist such as reverse osmosis, adsorption and ion exchange. However, adsorption has been preferred over the other due to its low cost and ease of operation. In this study, a novel adsorbent nanomaterial was prepared to remove fluoride from drinking water. The influence of different parameters such as pH, contact time, co-existing ions and dosage were investigated in order to understand the sorption behaviour of the adsorbent under varying conditions. The adsorption process best fitted with the Langmuir model with a maximum adsorption capacity of 62.5 mg/g. The adsorbent can be used under normal water pH=7. Anions and cations had no influence on the sorption capacity except for chlorides, carbonates and bicarbonates. The adsorbent reduced fluoride concentration from 10 ppm to approximately 1.5 ppm per 50 mg nanocomposite loading as recommended by World Health Organization. The synthesized nanocomposite can be used for defluoridation of water with high fluoride concentrations beyond recommended limit.

Today, one million people are drinking unhealthy water in the world. Each year 5 million people worldwide die due to the diseases caused by unhealthy drinking water. Unhealthy water creates a great risk, especially for children because of their undeveloped immune system (G8 Action Plan Decisions, 2003)1. Indeed, the World Health Organization estimates that 4.1 million children die from diarrhea, which can be inhibited by healthy water (WHO, 2010)2. In developed countries, it is observed that water is not only a basic consumption food, but also a lifestyle product. As mentioned in the Maslow’s hierarchy of needs, packaged water consumption reflects the choices related to the lifestyle as well as being a basic need at the bottom of the pyramid (Sipos, et al., 2007)3.  Water is increasingly becoming an important economic resource, and its public distribution is being privatized in many countries (e.g., France, England, Brazil, Australia, Bolivia and, recently proposed in Italy), opening new market opportunities for private investors. The consumption of bottled mineral water is significantly increasing worldwide and has become an important factor both for economic and health issues (King, 2008)4. Natural mineral water means microbiologically wholesome water, originating in an underground water table or deposit and emerging from a spring tapped at one or more natural or bore exits. This type of water cannot be sterilized, pasteurized or otherwise treated to remove or destroy microorganisms (European Commission, 2009)5. Hence, the researcher has made an attempt to find out the existing awareness and attitudes of consumers towards using packaged drinking water in Thoothukudi District.

In this study, Physico-chemical assessment of some commercial drinking water sold in bottles in Okada Town was evaluated to ascertain their compliance with World Health Organization (WHO) and Nigerian Industrial Standard (NIS): Nigerian Standard for Drinking Water Quality threshold limits using standard analytical methods. Seven different bottled water samples obtained from different manufacturers labelled BWA to BWG were analyzed physically and chemically. Physical examination of the samples showed that they were odourless, colourless, and tasteless. Chemical quality parameters examined were pH, Chloride (Cl-), total hardness (TS), Phosphate (PHO3-), Nitrate (NO3-), Sulphate (SO42-), Iron (Fe), Potassium (K), Sodium (Na), Manganese (Mn), Zinc (Zn), total dissolved solids (TDS), conductivity, turbidity, and total suspended solids (TSS). The pH values of 57.1% of the water samples (BWA, BWB, BWC, BWE & BWF) were within the standards. The remaining chemical quality parameters (Cl-, TS, PHO3-, NO3-, Sulphate SO42-, Iron Fe, K, NA, Mn, Zn, TDS, Conductivity, turbidity, and TSS) of the branded bottled water samples were within the standards for clean and safe drinking. Therefore, they were considered safe and fit for human consumption.

The radioactivity of selected sources of drinking water in Southern Bulgaria was investigated using 238U, 234U and 210Po activity measurements and dose calculation, respectively. The activities of 238U, 234U and 210Po varied from 226 to 826 mBq/L, 274 to 1623 mBq/L and < 0.6 to 25.5 mBq/L, respectively, being lower then derived concentrations for radioactivity in water intended for human consumption of the considered radionuclides, given in EC Directive 2013/51/EURATOM. In some drinking waters the mass concentration of natural uranium exceeded the set maximum chemical concentration level of 0.030 mg/L. A radioactive disequilibrium between 234U and 238U in water was detected. Based on the radionuclide activity concentrations total annual effective ingestion doses for adults, as well as contribution of each particular radionuclide to the total doses, were assessed and discussed. Тhe lowest contribution to the annual effective doses was found for 210Po and the highest for 234U. The results show that the annual effective doses of residents are below the reference level of 100 μSv/y according to the recommendations of the World Health Organization. The obtained new results are used to assess the radiation status of the investigated water.
