Water is a basic need of life, and more so, potable water is critical for healthy living. Shallow boreholes are now popular as the main source of drinking water in the Yenagoa metropolis due to the contamination of surface water and rainwater caused by poor management of wastes and crude oil facilities in the area. However, there are concerns about variations in the quality of groundwater across communities in the Yenagoa metropolis. Thus, this study assesses the spatial variations of physicochemical parameters of groundwater samples from 50 boreholes in the area, and results compared with recommended standards prescribed by the World Health Organization (WHO). Parameters analyzed were pH, electrical conductivity (EC), salinity, total dissolved solids (TDS), nitrate, chloride, sulfate, total alkalinity (TA), total hardness (TH), calcium, magnesium, sodium, potassium, and iron. Global Information System (GIS) technology was adopted to present the groundwater quality in respect to each physicochemical parameter, in thematic maps. The maps showed that groundwater was slightly acidic in most communities in Central and Northern Yenagoa like Ekeki, Swali, Akaba, and Okolobiri. In communities like Ogbogoro, Ekeki, Azikoro and Yenegwe the EC was higher than the standard permissible value according to the WHO. A very high concentration of iron was observed across all communities except a few like Nedogo, Okolobiri, Tombia, Gbarantoru, Ayama, Famgbe, and Ikibiri having iron-free groundwater. Concentrations of TDS, calcium, magnesium, nitrates, sulfates, potassium, and sodium were within permissible limits across all communities. Communities like Ayama-Ijaw, Obololi, Ikibiri, Ikudu, Bomodi, Tombia, and Akaibiri had good groundwater while Ekeki, Famgbe, Yenaka, and Kpansia boast of excellent groundwater quality, and other areas had either poor or unsuitable groundwater for consumption. Treatment is recommended for parameters with higher concentrations than the standard value stipulated by the WHO.

Kabul is one of the most populated cities in Afghanistan and providing resources to support this population in an arid climate presents a serious environmental challenge. The current study evaluated the quality of local Kabul Basin groundwater to determine its suitability water for drinking and irrigation purposes now and into the future. This aim was aided through groundwater parameter assessment as well as determination of Water Quality Index (WQI) developed from 15 observation points near the city. The results of our physicochemical analysis illustrate that groundwater in the majority of areas of the Kabul Basin is not generally suitable for human consumption, and in some cases the concentrations of many contaminants are higher than accepted health standards or water quality benchmarks. The aquifer underlies an arid landscape, and because of this 85% of the samples tested are very hard while just over 13% are classified as hard. Groundwater in the Kabul Basin is typically high in calcium and magnesium and overall classified as a calcium bicarbonate water type. Overall, more than 60% of the analyzed samples had concentrations higher than the World Health Organization (WHO) standard of total dissolved solids (TDS), 10% in total hardness (TH), about 30% in turbidity and more than 90% in magnesium. The results show that based on WQI, without treatment, roughly 5% of groundwater in the studied area is unsuitable for human consumption, while 13.3% is very poor and 40% is poor quality water. Approximately 40% of the assessed groundwater has good quality and could be used as drinking water for future development. Groundwater in some areas shows evidence of pollution and high dissolved solids content, rendering these sources unsuitable for either drinking or irrigation purposes.

Some sources of drinking water in Kari Estate in Bauchi Metropolis were analyzed for physicochemical contents and coliform contamination. A total of five samples were collected from different sources as follows: 2 sachets water, 2 wells, and tap water. The physicochemical analysis included the determinations of temperature, pH, electrical conductivity, total dissolved solids, turbidity, colour, suspended solids, odour, taste, total hardness, iron, nitrate, nitirite, manganese, ammonia, fluoride and cyanide. The two wells had total coliforms of 6 and 10 and faecal coliforms of 4 and 5 respectively. Tap water had total and faecal coliforms of 7 and 3 respectively. E. coli were identified in the samples from wells while Bacillus sp. were found in the tap water. Although the physicochemical contents of the samples were normal range, coliform counts of the wells and tap water were above those set by the Nigerian Industrial Standards (NIS) and the World Health Organization (WHO) standards. Presence coliforms above the standards indicates contamination and that the water may be unsafe for drinking. The presence of E. coli suggests that improvement in monitoring and water hygiene practices should be employed to improve the drinking water quality.

Present communication deals with study of physico-chemical parameters such as pH, electrical conductivity (EC), total dissolved solids (TDS), total alkalinity (TA), calcium hardness (CaH), magnesium hardness (MgH), total hardness (TH), chloride (Cl-), fluoride (F-), sodium (Na+), potassium (K+), dissolved oxygen (DO), biochemical oxygen demand (BOD), chemical oxygen demand (COD) and sulphate (SO42-) of water samples of bore wells of forty villages of Gandhinagar taluka of Gujarat state,India. The experimental values of water samples were compared with standard values given by World Health Organization (WHO) and United State Salinity Laboratory for drinking and irrigation purposes respectively. Water Quality Index (WQI) was also calculated to know the over all quality of water samples. The statistical analysis like mean, standard deviation (SD), coefficient of variance (% CV), analysis of variance (ANOVA),t-test, coefficient of correlation (r) and regression analysis of obtained data were carried out. The results show that the quality of water is poor and quite good for drinking and irrigation purposes respectively. The variance was found significant at 1% level of significance in case of sodium and potassium content and at 5% in case of total alkalinity and dissolved oxygen among the four regions (North, South, East and West) of Gandhinagar taluka. The linear relation also established for each pair of water quality parameters of studied water samples.

Optimum fish production is greatly dependent on the physical, chemical and biological qualities of water. Hence, successful fish pond management requires an in-depth understanding of water quality. A study to assess heavy metal (Cr, Cd, Mn, Pb and Zn) contamination and physicochemical parameters of water samples from eight selected fish ponds in Sunyani, Ghana, was conducted. The parameters included temperature, pH, salinity, total hardness, electrical conductivity (EC), chemical oxygen demand (COD) and biological oxygen demand (BOD). The results revealed detectable Mn and Zn levels in all the selected fish ponds; with Mn levels in three ponds being significantly higher than the World Health Organization (WHO) recommended limit (< 0.500 mg/L). Of the three samples, which showed detectable Cr and Cd levels, concentrations of two exceeded the permissible limits. Pb was below the detection limit in all the samples whilst Cu levels detected in two of the ponds were below the permissible limit. The investigated physicochemical parameters had the following ranges: temperature 26-29 C, pH 5.8-8.2, BOD 0.3-20 mg/L, Total Dissolved Solids (TDS) 37-249 mg/L, EC 73.67-498 μS/cm, total hardness 0.8-5.7 mg/L, salinity 0.03-0.22 psu and COD 2.9-9.7 mg/L. Most of these values were within WHO recommended levels. The findings suggest that regular monitoring of the heavy metal load is necessary to guard against long-term effects of its presence in the water, influencing fish and human uptake.

Hydrogeochemical analyses were conducted on groundwater sampled from the Saloum aquifer, in southern Senegal. The objective was to identify the chemical processes that control hydrochemistry and to assess the quality of groundwater for determining its suitability for drinking and agricultural purposes. Water samples were collected from 79 wells during the dry season in May 2012, and were subjected to analysis for chemical characteristics (major ions), pH, electrical conductivity (EC) and total dissolved solid (TDS). The dominant hydrochemical facies observed for the groundwater samples are NaCl and CaHCO3. Gibbs plot depicts predominance of rock water interaction and evaporation processes controlling the water chemistry. Percentage of Na+, Residual Sodium Carbonate (RSC), Total Hardness (TH) and Sodium Adsorption Ratio (SAR) values were calculated. The results were compared with the standard guideline values recommended by the World Health Organization and agricultural water standards. The TDS in groundwater is less than 1200 mg/L and SAR values are less than 10. RSC values overall are less than 1.25 meq/L. Results show that the groundwater in the area has generally a low hardness and is fresh (95%) to brackish. The majority of groundwater samples are appropriate for domestic uses. The indexes for water irrigation compared with standard limits revealed that most of the Saloum groundwater samples fall in the suitable range for irrigation.

Sachet Water

This study presents the result obtained from the quality assessment of some sachet water produced in Irele, Ondo State, Nigeria. Eight different brands of sachet water certified by the National Agency for Food and Drug Administration and Control (NAFDAC) representing the western, northern, eastern, central and southern part of Irele were obtained, their physicochemical characteristics and microbiological parameters were investigated using standard analytical procedures to determine the level of agreement with World Health Organization (WHO) and Nigerian Industrial Standard (NIS) requirements for drinking water. The results from the Physico-chemical characteristics temperature, electrical conductivity, pH, total dissolved solids, total hardness, total alkalinity, nitrate and chloride were in the range of 6.2 - 27.0 oC , 77.2-142.3 μS/cm, 7.40 -7.60, 47.7 - 99.5 mg/L, 11.3 - 51.3 mg/L, 13.20 - 70.0 mg/L, 0.8 to 2.5 mg/L and 0.01 - 0.02 mg/L respectively. The concentrations of iron, copper and manganese were in the range of 0.01 - 0.02 mg/L, 0.13 - 0.18 mg/L and 0.01- 0.6 mg/L. The concentrations of cadmium, mercury, lead, and arsenic were not detected in the sachet water studied except in sample H were their concentrations were 0.003, 0.001, 0.01, and 0.01mg/L, respectively. The microbial quality of the studied sachet water was within the WHO recommended standard. All the studied parameters have their values within the recommended limit set by WHO except for sample H with a manganese concentration above the set standard. There is a need for NAFDAC and other water monitoring agencies to focus on promoting the safety of drinking water, particularly sachet water. The Sources of water, production processes, and environment should be inspected regularly by monitory agencies to certify that there is no deviation from recommended standards.
