This case study characterizes the drinking water quality by using the multivariate technique. The spatial variation of the physico-chemical and heavy metals parameters toxicity with the drinking water quality based on 28 water treatment plants in Selangor, Malaysia from 2009 to 2012 was evaluated. The objectives of this study are to analyze the physio-chemical activities and heavy metals activities in the collected drinking water samples from the treatment plants, and to detect the source of pollution for the most revealing parameters. The discriminant analysis (DA) and the principal component analysis (PCA) are the chemometric techniques used to investigate the spatial variation of the most significant physico-chemical and heavy metal parameters of the drinking water samples. The classification matrix accuracy for standard mode of DA, forward stepwise and backward stepwise for the physico-chemical and heavy metal parameters are excellent. PCA highlighted 13 significant parameters out of 18 physico-chemical water quality parameters and 14 significant parameters out of 16 heavy metal parameters. PCA was carried out to identify the origin and source of pollution of each water quality parameters. For that reason, this study proves that chemometric method is the principle way to explain the characteristic of the drinking water quality.

In developing countries, one of the main concerns is contaminated drinking water. The rise in demands and development pressure is also changing the characteristics of water resources. The freshwater sources are increasingly being depleted as surface water resources have become too polluted for human consumption. To address this issue, water samples were collected from industrial clusters in Kashipur town and from the Kosi River. Industrial effluents were obtained from six locations and samples from twelve sites were drawn from the groundwater. Water supplies have been sampled from boreholes, open wells, rivers and some piped waters throughout the town of this area. The specimens are examined for their concentration of physico-chemical and heavy metals to detect pollution issues and recommend acceptable solutions. Results of the assessment confirmed that in the studied area there was the presence of various health and aesthetic parameters of concern. Apart from Kosi bank and Cheema drain, most of the effluents are acceptable for discharge into the water body. Most of the groundwater surrounding these three industries was not suitable as groundwater samples for drinking purposes at Dhouri pratha 1, Glycol gate no.1, Artesian well sugarcane center, petrol pump, and Parmanandpur-2. In addition, factors of environmental significance, such as turbidity, iron, and manganese, have a negative impact on many groundwater sources. Using alternative sources, improving water supply structures and treating water can be solutions to improve drinking water quality in this area.

Bottled water is generally considered safe for drinking. However, several studies have reported the substandard quality of bottled water. Physico-chemical assessment of ten different brands of bottled water distributed in Bhaktapur Municipality was carried out from January 2018 to March 2018. In total, one hundred bottled water samples consisting of ten different brands were collected randomly from various retail outlets. Eight selected physico-chemical and microbiological parameters were analysed following standard methods, and the results were compared with the Nepal Drinking Water Quality Standard (NDWQS) (2005). Out of one hundred samples, sixty-nine samples did not comply with the standard pH limit. Other physico-chemical parameters were found to comply with the standard though variations were observed in the concentrations among different brands. Microbial contamination was not found in any brands of the bottled water samples considered in this study. However, it is necessary to examine other contaminants such as heavy metals, minerals, and chemicals to know the overall quality of water. Moreover, the regulatory bodies are required to strictly monitor water processing companies for the maintenance of the quality of bottled water.

Diarrheal diseases associated with inadequate supply of potable water are the leading causes of mortality among children under five years in developing countries. In Nigeria, women are the water managers in most households. However, there is dearth of information on the effect of women’s handling practices on drinking water quality. Therefore, this study was aimed at assessing the drinking water quality and handling practices among women in selected rural households in Oshimili North Local Government Area of Delta State, Nigeria. Paired drinking water samples from available sources and Household Storage Containers (HSC) were assessed for physico-chemical and bacteriological parameters using standard methods. The data obtained were compared with the WHO guideline limits. Water samples with 0, 1-10, 11-50 and > 50 E. coli/100 mL were graded as A, B, C, and D corresponding to excellent, acceptable, unacceptable, and grossly polluted quality, respectively. Pre-tested semi-structured interviewer-administered questionnaire was used to elicit information from the respondents. A 30-point scale was used to assess water handling practices. Handling practice scores greater or equal to mean handling practice score were grouped into good and those less than that were grouped into bad handling practices. Data were analyzed using descriptive statistics and One-way ANOVA at α = 0.05. The results showed physico-chemical parameters for both sources and households within WHO guideline limits. The mean total coliform counts for all sources and household containers exceeded permissible limits. E. coli  was not detected in harvested rain water while counts for borehole was 10.2 ±2.2 (A) and for stream sources was 44.6±33.3 EC/100 mL (B); drinking water stored in HSC had 36.8±32.3 (A) EC/100 mL, borehole had 62.31±33.2 (C) and stream had 30.00±33.2 (B). Mean handling practice score was 19.4+6.6. Majority (60.0%) practiced some water handling technique. Drinking water from assessed sources was of poor microbial quality and it significantly deteriorated when stored in household storage containers. Therefore, there is a need to improve the microbial quality of drinking water at sources and household level through the supply of simple, acceptable, low-cost treatment methods and hygiene education.
