The analysis of groundwater quality of important town areas of Thrissur district was carried out during the pre-monsoon period of 2014. The Physicochemical and biological parameters such as temperature, turbidity, electrical conductivity, total dissolved solid, pH, alkalinity, chloride, salinity, total harness, calcium, magnesium, iron, phosphate, sulphate, dissolved oxygen, biological oxygen demand, chemical oxygen demand, total coliform count and E. coli were determined. Most of the physicochemical parameters were observed above the desirable limit but below the permissible limit of drinking water standards of World Health Organization (WHO). Total coliform bacteria count values of different samples are within the permissible limit. The studies reveal that samples from Thrissur town (T), Guruvayoor (G) and Laloor (L) shows the presence of E.coli bacteria. All other samples were negative for E.coli bacteria. Dumping of wastes near road sides, flood due to heavy rains, improper waste management in hospitals, markets, flats etc increases the pollution of ground water. The results were compared with WHO guidelines, 2006 and Bureau of Indian Standards (IS: 10500, 1991) desirable limits for drinking water.

Groundwater Assessment

Municipal solid waste collected in Nigeria are often disposed of in uncontrolled dumpsites and/or burnt in the open spaces and consequently causing significant pollution on surface water, ground water and the air. An investigational study was carried out on the level of pollution on groundwater near Gbagede dumpsite in Kwara state. Ground water samples, GW1, GW2, GW3 were taken at three different locations: 186 m, 290 m, and 326 m from the edge of the dumpsite. Physicochemical parameters evaluated include; pH, total hardness, Total Dissolved Solids, Total Suspended Solids, alkalinity, turbidity, Chemical Oxygen Demand, Biochemical Oxygen Demand, Dissolved Oxygen, Nitrate ion, Chloride ion, Sulphate ion, Electrical conductivity, Calcium ion and Magnesium ion using standard laboratory procedures. The results of the evaluations were compared with the World Health Organization (WHO) and Nigerian Standard for Drinking Water Quality (NSDWQ) to establish its suitability for human consumption. Results fell within the stipulated range of WHO and NSDWQ standard for drinking water. It was however observed that the water quality improves with distance from the dumpsite. Statistical analyses indicated mild differences among all the parameters tested for in the samples at 95% confidence level. Uncontrolled accumulation of leachates from the dumpsite may pose potential risk to the source of water for the community in the near future. It was recommended that the dumpsite be relocated from the current residential area.Key Words: Groundwater, Assessment, Contaminants, Solid-waste, Water quality

Quarrying as a land use is a potential source of water pollution but lack of access to safe drinking water has impelled people to make use of pond water from quarry sites. This study investigated the physico-chemical parameters and heavy metals of water samples collected at China quarry site in Ngwogwo Ivo Local Government of Ebonyi State, Nigeria. The concentrations of Cd (0.01±0.00 to 0.02±0.00 mg/l), Pb (6.70±0.78 to 7.87±1.08 mg/l), Ni (1.03±0.04 to 1.37±0.04 mg/l), As (1.99±0.02 to 2.35±0.09 mg/l), Fe (3.66±0.44 to 4.18±0.04 mg/l) and Zn (2.47±0.06 to 3.17±1.13 mg/l) were higher than the permissible limit of drinking water by World Health Organization, WHO and Standard Organization of Nigeria, SON. Also, the values of biochemical oxygen demand, BOD (37.57±1.44 to 53.13±0.86 mg/l), chemical oxygen demand, COD (59.55±0.51 to 61.28±0.64 mg/l), dissolved oxygen, DO (5.14±1.51 to 5.75±1.09 mg/l), Mn (3.64±0.91 to 5.10±1.27 %) and Ca (91.88±0.18 to 102.83±0.59 %) were higher than the permissible limit recommended by WHO. Consequently, it is recommended that quarry workers and inhabitants of Ngwogwo should be discouraged from making use of the pond water since it is not fit and will expose them to serious health challenges. In addition, Ebonyi State Government should demand Environmental Impact Assessment report from miners before issuing operating license to them.

Abstract: During present study, 30 samples of drinking water from five different sources of drilled well from Kifry city have been collected and investigated for the levels of their physiochemical and Microbiological Coliform. Chemical tests were performed include tests of some soluble inorganic ions, such as chloride (Cl1-) and calcium (Ca2+), potassium (K+) sodium (Na+), magnesium (Mg2+). While the conductivity, pH, total dissolved solid (TDS), and turbidity tests belong to the physical tests. The results of chemical and physical test demonstrate the water of drilled wells in study area is possible for drinking according to Iraqi standard limits for drinking water. While their microbiological (coliform) properties have been investigate, the microbiological test includes test (MaCconkey Broth) methodology to coliform for any different drinking water. As well as the international organization World Health Organization (WHO) ranges for qualities of drinking water were used for results comparisons, but the (drilled well) water in Imam Mohamed area isn’t suitable for drinking water, according to the (WHO) ranges for drinking water.

This study aimed to assess and compare the quality of groundwater in the city of Al-Marj in Libya with the international standard guidelines for drinking water recommended by the World Health Organisation. An evaluation of the groundwater wells in the study area was conducted. Standard techniques, such as Minitab (v. 16) and ArcGIS (v.10.2), were used for the analytics of the physicochemical and biological parameters of the groundwater samples. An assessment of the calculation of groundwater quality was conducted on the basis of temperature, pH, turbidity, electrical conductivity, total dissolved solids, chloride, sulphate, bicarbonate, total hardness, calcium, potassium, magnesium, ammonia, ammoniacal nitrogen, nitrate, sodium, copper, iron, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, total suspended solids, Escherichia coli and total coliform bacteria. Results indicated that most groundwater wells in the study area display a higher concentration of several parameters compared with the permissible limits of drinking water; thus, the water in these wells is chemically and biologically unsafe for drinking purposes. On the basis of the above results, routine water quality monitoring should be performed and additional water filtration plants should be installed by the local government to obtain safe drinking water.

AbstractThis study aimed to determine the quality of drinking water supplied in different types of food stalls in Jashore Municipality, Bangladesh. A total of 35 water samples were collected from different tea stalls, street side fast food stalls, normal restaurants and well-furnished restaurants. The water quality was evaluated by determining the distinct physical, chemical and biological parameters. The results revealed that the water used in the food stalls and restaurants for drinking purpose was in desired quality in terms of turbidity, electrical conductivity, pH, total dissolved solids, nitrate (NO3−), sulfate (SO42−), phosphate (PO43−), chloride (Cl−), sodium (Na) and potassium (K) concentrations. The values were within the permissible limit proposed by the Bangladesh Bureau of Statistics and the World Health Organization. Concentrations of calcium (Ca) and magnesium (Mg) found in several samples were higher than the World Health Organization standard. Iron (Fe) concentrations were higher than the permissible limit of the World Health Organization. Only 46% exceeded the permissible limit of Bangladesh Bureau Statistics. The threatening result was that the samples were contaminated by fecal coliform, indicating that the people of Jashore Municipality may have a greater chance of being affected by pathogenic bacteria. The drinking water provided in the street side fast food stalls was biologically contaminated. The findings demonstrate that the drinking water used in food stalls and restaurants of Jashore Municipality did not meet up the potable drinking water quality standards and therefore was detrimental to public health.

Chattogram is the second most populated city in Bangladesh. This port city faces a serious threat mainly due to the lack of safe drinking water. This study was conducted for determining drinking water quality of groundwater sources in Chattogram city. The study was performed in the BCSIR laboratory, Chattogram. It was carried out for a period of six months from 1st July, 2018 to 31th December, 2018. Total six water samples were collected from three different locations (Baluchora, C&B colony and Khulshi area). Each sampling location consists of two separate sampling points. Physicochemical parameters of the collected samples like Temperature, pH, Electrical Conductivity (EC), Total dissolved solid (TDS), Hardness, Turbidity and concentration of Cl, As, Mn, Fe, Pb, Cr and Cd were examined. Microbial parameters like Total Coliform (TC) were also measured. All the analyzed parameters compared with BSTI and WHO drinking water quality standards to understand the overall ground water quality status of the study area. The results reveal that water samples in almost all locations were contaminated with microbial contamination and that the range of physico-chemical parameters was not adequate for consumption. Preliminary treatments like boiling, filtering etc are required before using groundwater for drinking and the necessary measures must be taken for a safe alternative source of drinking water.

This study examined the hydrochemistry of surface water along the River-Rima floodplain area. Five sampling locations were purposively selected, and, in each point, three samples were taken from surface water (river). The sampling was repeated after 20 days. Thus, a total of 30 samples were collected. Water samples obtained were subjected to laboratory tests. Results revealed that BOD, TDS, Mg2+, and Fe3+ are above the World Health Organization (WHO) and Standard Organization of Nigeria (SON) reference guidelines for drinking water quality. Isolates detected from the coliform bacteriological analysis include Enterobacter aerogene, Escherichia coli, and Citrobacter freundii with most of the samples showing coliform bacteria growth above the SON standard for drinking water. Hence, the water in the River-Rima floodplain of the Wamakko area is of low quality and unsafe for drinking. Results of principal component analysis (PCA) revealed external influences such as pollutant wash off and rock weathering as controls on hydrochemistry of surface water. There is some indication of anthropogenic inputs (Cl-, NO3-, and PO42-) based on hierarchical cluster analysis. Elements including Cl-, NO3-, and PO42- are increasingly added into surface water from human activities, mainly agriculture, and municipal sewage.
