Potable ground water quality is at risk due to contamination by pollution, sewage, industrial effluents along the nearby areas of Mula-Mutha river banks in eastern metropolitan region of Puneand needed treatment especially disinfection for making it domestically usable. The phytoremediation is one of the important useful method when considered for treatment of water in rural area. The study involved monitoring the quality of ground water in the selected areas along the banks of the river using physicochemical and biologicql parametersin continuation with our earlier studies. For the disinfection treatmentthe commonly found plantsin the area viz. Neem, Tulsi, and Amlawere selected and for the water samples, onsite river water samples and bore well water samples were used. The plants leaves were extracted by water and alcohol and the extracts in dose response manner were used to treat the water. The treated water was monitored for presence of Total coliform and E.coli, the indicators of contamination, using petri film method. The resultsshowedrandom presence of total coliform and E.coli in bore well water samples indicating contaminationand the need fordisinfection.The disinfection study showed that alcoholic leaves extracts were more potent in disinfecting the water samples than aqueous extracts. The complete disinfection by alcoholic extracts was shown at concentration of 21.12mg, 42.8mg and 24.07mgfor Tulsi, Neem and Amla respectively.

It is necessary to ascertain the quality of irrigation water at Anbil Dharmalingam Agricultural College and Research Institute farm in order to monitor the possible effects of the sodic irrigation water on the soil. Irrigation with sodic water enhances soil sodicity built up in soils of experimental farm which leads to adverse effects on soil physical, chemical and biological properties, not fitted for farming. In areas where ground water is sodic and where good quality surface water supplies are either inadequate or not available at all and the farmers are left with no option but to use sodic ground water for irrigation purposes, which pose grave risks for soil health and environment. The quality of sodic water can be improved by treating with gypsum. Due to gypsum dissolution calcium and sulphate ions come in soluble form in irrigation water. Research conducted at Anbil Dharmalingam Agricultural College and Research Institute Trichy for reclamation of sodic bore well water revealed that the sodic bore water samples collected from bore well 1 (AMP shed) having initial Residual Sodium Carbonate (RSC) of 8.0 meq /lit and bore well 6 (Boys hostel) having initial RSC of 6.2 meq /lit indicated the decrease in RSC upto - 0.6 meq / l and 1.2 meq / l respectively due to gypsum treatment with 0.1 per cent (12.50 tons/ha) and 0.35 per cent ( 43.75 tons /ha ) at the retention time of 1 hour to irrigate 1 ha paddy field throughout crop establishment stage. It was concluded that for lowest retention time higher doses of gypsum was required for sodic water reclamation. As we increased the retention time, the required gypsum quantity was also minimized as observed for bore well 1 (AMP shed 8 meq/l)) sodic water samples with gypsum dose of 0.15 per cent (18.75 tons /ha) with the retention time of 4 hours. These findings were very much helpful for the farmers of Manikandam block, Tiruchirappallii district having secondary sodicity built up in soils due to sodic water irrigation during summer.

The quality of harvested rainwater in Aule area of Akure, South western Nigeria was assessed in this study. Water samples were collected from 25 rain water storage tanks within the study area and a well was used as a control. The water samples were subjected to detailed laboratory analysis and the results obtained was compared with World Health Organization (WHO) standard for drinking water. The turbidity values ranged from 2.7 to 9.1 NTU for the harvested rainwater samples while the well water sample had a turbidity of 2.3 NTU. The conductivity values for the rainwater samples ranged from 101 to 1328 Ωs/cm. The conductivity value was lower in the well water (164 Ωs/cm) than in most of the harvested rain water samples. The pH of the harvested rainwater ranged from 6.1 to 7.4 with 36 % of the water samples having a pH less than the WHO minimum limit of 6.5. The pH of the well water sample was 7.4 and was within the WHO acceptable limits of 6.5 to 8.5. All the sampled rainwaters and well water had bacteria in them. The total bacterial content of the rain water samples ranged from 05 to 28 CFU/100 mL, while that of the well was 05 CFU/100 mL. The total coliform contents of the rainwater samples ranged from 03 to 18 CFU/100 mL, while that of the well was 02 CFU/ 100 mL. Based on the results obtained from this study, it is recommended that harvested rainwater be treated to kill contaminating microorganisms and to reduce the health risks associated with its consumption.

The limited availability, accessibility and deterioration of the water quality in Kathmandu valley have led to the high demand of ground water. This study aims to evaluate ground water quality of the Kathmandu valley. In this study, the physio-chemical parameters of water samples were performed using standard procedures. Also, total coliforms were enumerated using standard membrane filtration technique to quantify the bacterial contamination. Water samples were collected from July 2017 to July 2018. The results revealed that 56% and 73% of well and boring water samples, respectively exceeded standard value of iron recommended by National Drinking Water Quality Standards, 2005. Likewise, ammonia content was higher in 41% of well water and 35% of boring water samples than standard. However, few numbers of water samples were contaminated with arsenic (0.27% and 2.6% of well and boring water samples, respectively) and nitrate (3% and 8% of well and boring water samples, respectively). Besides, 96% of well water samples and 88% of boring water samples were contaminated with total coliform bacteria. Our data indicated that groundwater quality of Kathmandu valley was poor, which was not suitable for direct drinking purposes. Therefore, regular monitoring and treatment of groundwater is recommended before using accordingly.

This study was carried out to investigate the physicochemical and bacteriological quality of well water samples in Ido community. Thirty water samples were collected from five different wells ( six samples from each well) and subjected to standard microbiological and physicochemical analysis. All physicochemical properties showed difference (p<0.05) in all the wells analyzed except temperature and turbidity. Temperature ranged between 25.3±3.50C and 26±2.350C; pH, 6.3±0.7 and 6.9±0.3; electrical conductivity, 127.6±1.9 and 157.8±7.7μs/cm; total suspended solids, 25.2±8.9 and 53.2±1.8mg/l; turbidity, 0.15±0.7 and 1.20±1.4NTU; dissolved oxygen, 4.40±2.8 and 5.35±2.1 mg/l; Biological Oxygen Demand, 9.40±2.8 and15.4±2.8mg/l; Chemical Oxygen Demand, 177.2±1.6 and 260.3±1.6mg/l; chloride, 59.8±8.5 and 101.2±2.6mg/l and total hardness, 246.6±1.9 and 395.6±2.7mg/l. All values fell within WHO standards except Chemical Oxygen Demand (WHO Standard 40mg/l) and total hardness (WHO Standard 100mg/l). Results of microbial population did not show any difference (p>0.05) across the wells. However, Total Heterotrophic Bacteria ranged from  2.15±0.91×104 to 5.3±0.86×104cfu/ml; total coliform, 3.00±0.77×104 to 6.18±0.73×104 cfu/ml; Total feacal coliform, 2.61±0.71×104 to 4.39±0.76×104 cfu/ml; Total vibrio count, 2.68±0.81× 103  to 4.4±0.86×103 cfu/ml; Total salmonella shigella count. 2.02±0.84×103 to 4.8±0.95×103 cfu/ml. Total coliform bacteria ranged from 220 to > 1600 coliform MPN index /100ml-1, while thermo tolerant coliform bacteria ranged from 220 to  1600 coliform MPN index /100ml-1.  A total of forty bacterial isolates belonging to ten genera were identified. They include species of Bacillus 22 (26.4%), Staphylococcus 14(16.8%), Vibrio 13(15.7%), Serratia 6(7.3%), Enterobacter 6(7.3%), Chromobacterium 4(4.8%), Salmonella 4 (4.9%), Shigella 4(4.8%) and E. coli 4(4.8%).  This  result highlights the fact that  well water in Ido community are not safe microbiologically for drinking without additional treatment such as boiling or disinfection and this could lead to outbreak of water borne diseases. Good and proper environmental and personal hygiene is advocate especially by the users of those wells to prevent their contamination with bacterial pathogens.

The thinly populated Balkhash District of Kazakhstan’s Almaty Region lies in the lower reaches of the Ili-Balkhash basin, which is shared by China and Kazakhstan. The district is arid and heavily dependent on inflows of surface water, which are threatened by the effects of upstream population growth, economic development, and climate change. The quality of drinking water from centralized water systems and tube wells in nine villages of the district was analyzed, and the organoleptic properties of water from these sources was also assessed by an expert and via surveys of local residents. Although most samples met governmental standards for the absence of chemical impurities, high concentrations of mineralization, chlorides, boron, iron, and/or uranium were present in some well water samples. Levels of these pollutants were as much as 4-fold higher than governmental maxima and as much as 16-fold higher than concentrations reported previously in surface water. All centralized water samples met standards for absence of microbial contamination, but total microbial counts in some well water samples exceeded standards. Organoleptic standards were met by all the water from five villages, but centralized water from one village and well water from four villages failed to meet standards based on expert judgment. Residents were, for the most part, more satisfied with centralized rather than well water, but there was no obvious relationship between the failure of water to meet standards and the locations or populations of the settlements. This is the first comprehensive assessment of groundwater used for drinking in the lower Ili-Balkhash basin, and although it relies on a limited number of samples, it nevertheless provides evidence of potentially serious groundwater contamination in the Balkhash District. It is thus imperative that additional and more detailed studies be undertaken.

The Quality of Well Water around Final Garbage Dump (FGD)  Rawa Kucing, Tangerang, IndonesiaFGD Rawa Kucing is located at Sultan Iskandar Muda Street, Kedaung Wetan, Neglasari, Tangerang, Banten, Indonesia. It serves 1000 tons of garbage per day from 13 districts in Tangerang. The volume of garbage in Kota Tangerang increases from 1,212,264 m3 in 2008 to 4,590,724 m3in 2012.Well water is the main source of water for people around the FGD RawaKucing. They use well water for bath, wash,  and toilet (BWT) and other needs. Garbage decomposition which makes pollution around FGD Rawa Kucing can accur in air, water, and soil. Waste accurs in water and soil caused by leachate. Leachate can easily  spread through rainwater runoff and it absorbs to the ground and polluting it including well water around it. Contaminated well water can decrease the quality of water physically, chemically, and microbiologically.Groundwater samples taken from residents' well water around FGD Rawa Kucing  and they were represented by three groups which have distance 100 m - 3 km from FGD. Each group consisted of three samples which were taken from well water having depths between 8-18 m. The examination of the quality of well water should be made in accordance with the Regulation of the Minister of Health of the Republic of Indonesia No.416/MENKE /PER/IX/1990 on the Conditions and Control of the Quality of Clean Water and Quality Regulation of the Minister of Health of the Republic of Indonesia No. 492/MENKES/PER/IV/ on Requirements and Quality Control of Drinking Water.The quality of well water around FGD Rawa Kucing showed that there were the decreased quality water after testing with several parameter tests. There were six examination parameters which concentrate on exceeding the required quality standards that of TDS (1600-1764 mg/L), Nitrates (10.5-37.8 mg/L), Ammonia (3.50-66.21 mg/L), Iron (1.054-7.063 mg/L), Manganese (1.085-10.130 mg/L), and Total Coliform (80-130 colonies/100 mL).Keywords : Well water, leachate, TPAS, pollution, water qualityABSTRAKTPAS Rawa Kucing berada di Jalan Sultan Iskandar Muda Kelurahan Kedaung Wetan, Kecamatan Neglasari, Kota Tangerang, Banten dan mengangkut 1000 ton sampah/hari dari 13 kecamatan.Volume sampah di Kota Tangerang terus meningkat dari tahun 2008 sebesar 1.212.264 m3 sampai pada tahun 2012 telah mencapai 4.590.724 m3.

Spatial and temporal changes in the pH, electrical conductivity (EC), TDS, TSS, BOD, COD and concentration of toxic metals viz. cadmium (Cd), iron (Fe), chromium (Cr), lead (Pb), nickel (Ni), zinc (Zn) and copper (Cu) were assessed in the waste water contaminated with untreated or inadequately pretreated industrial effluents from pharmaceutical industries located in Selaqui area and sugar industry and distillery located in Doiwala area of Dehradun. Four effluent samples A, B, C, D collected from manufacturing and processing industries located in the study area and two ground water samples E1 & E2 contiguous to Selaqui industrial hub and Doiwala industrial stretch respectively, were analyzed  using standard physico-chemical methods. In order to delimit the temporal changes in parameters, samples were collected in three batches at three consecutive seasons of a year. Analyses at STP condition revealed that pH values of ground water samples remained fairly unchanged at 7.01 + 0.14 & 6.98 + 0.04 for E1 & E2 respectively, for two regional variations and three seasonal variations. EC (mmho/cm) varied non-uniformly with highest value of 0.479 observed for sample A in batch 1 whereas lowest value of 0.122 recorded for sample D in batch 3. TDS in effluents of distillery and sugar industry were found to be 3-6 folds higher than the same for effluents from pharmaceutical industries across all seasons. BOD and COD values for the effluents of distillery and sugar industries were recorded unexpectedly higher than corresponding values in effluents from pharmaceutical industries in all the three batches. TSS was very high in the range of 1500 to 4500 mg/l in all the effluent samples except the ground water samples. Highest concentration of heavy metal detected was iron with concentration of 10.80 mg/l. Cr, Pb, Cd and Ni were found to be above the permissible limit recommended by WHO standards. A plausible analysis is made to interpret the wide range variation of the parameters in the light of spatial and temporal change aspects and necessary pretreatment measures to bring down the magnitude of contamination within consent level are suggested.
