<p class="1Body">The research was conducted to assess the <em>aflaj</em> water quality in Al Jabal Al Akhdar, Oman. 9 <em>aflaj</em> were sampled during summer and winter seasons in 2012-2013 to evaluate for the physico-chemical characteristics of major quality parameters; and assess the suitability of <em>aflaj</em> for irrigation purposes. Samples collection, handling and processing followed the standard methods recommended by the <em><em>American Public Health Association </em></em><em>and </em>analysed in quality assured laboratories using appropriate analytical methods and instrumental techniques. The quality parameters of the selected <em>aflaj</em> water indicated their suitability for irrigation as most of the quality parameters were within the permissible limits set by Omani regulations of wastewater reuse for irrigation. These selected water resources are excellent or good in quality for irrigation purposes based on the evaluation of different hazards parameters including the salinity-alkalinity hazards which indicate good to admissible water based on electrical conductivity and sodium adsorption classification; and water quality indices which reveal high or moderate classes, indicating the suitability of <em>aflaj</em> for irrigation of the majority of crops and soils. This study is a first comprehensive assessment towards providing indicators and classification indices on irrigation water quality of this fragile mountain ecosystem, which will be the basis for future planning decisions on agricultural demand management measures to protect these principal resources for agricultural production in Al Jabal Al Akhdar.</p>

The water quality of seafronts and beaches of Mumbai is under pressure and deteriorating due to discharge of partially treated sewage and wastewater through point and nonpoint sources. The objective of the study was to assess the water quality and to correlate physico-chemical and bacteriological parameters for establishing relationship, association and dependence on each other. The water quality parameters were selected as per SW II standards specified by Central Pollution Control Board, India and nutrient parameters as strong indicators of sewage pollution. Box and whisker plots were generated for evaluating spatio temporal variation of water quality which suggest influence of organic pollution mostly at Mahim and Dadar in the form of outliers and extremes. Pearson's correlations were estimated between parameters and found significant correlation with each other indicating influence of sewage on water quality. The water quality of beaches and seafronts were found unsafe for recreational purposes. The study suggested that designated water quality can be achieved by restricting nonpoint source through improvement in wastewater collection systems, appropriate level of treatment and proper disposal.

Abstract Wetlands are among the most productive ecosystems in the world. They provide numerous beneficial services for people and wildlife. The most important services are improving water quality and wildlife habitats. The complex, dynamic relationships between the organisms inhabiting the wetland environment are called food webs. Both water quality and high levels of nutrients are crucial for improvement of the food web. Many bird species rely on wetlands for food, water and shelter, especially during migration and breeding. The water quality of Choghakhor Wetland was evaluated from April 2010 to March 2011, by measuring some physicochemical parameters and doing benthic macroinvertebrate analysis. Sampling was done in 3 replicates with alternation of 45 days. The resolute was divided into more than 25 identified macroinvertebrate families which belonged to 5 classes and 12 orders. The correlation between biological indices and water quality parameters showed that bioindicators and community indices could be used for the evaluation of water quality in this wetland. The water quality of Choghakhor Wetland was classified as average or in the severe pollution class, according to these indices. It can be concluded that bird migration is at risk due to the decline in the overall health of the Choghakhor Wetland ecosystem.

Water is one of the renewable resources essential for sustaining all forms of life and quality of drinking water is very fundamental for human health. Human activities such as mining act as sources of water contamination which consequently lead to ecological, environmental and health problems. To the best of our knowledge, no study has been conducted around the Thundulu Phosphate Mine to establish the quality of drinking water. In this regard, this study was carried out to evaluate the physico-chemical water quality parameters of areas surrounding the Thundulu Phosphate Mine in Phalombe District. Groundwater samples from the villages surrounding the Phosphate Mine were collected both during the wet and dry seasons for analysis of physico-chemical water quality parameters (pH, electrical conductivity, turbidity, nitrate, chloride, sulphate, fluoride, iron, calcium and magnesium). The study also investigated microbiological water characteristics mainly Escherichia coli and faecal coliforms. Results showed that pH, electrical conductivity, turbidity, nitrate, chloride, sulphate, phosphate, calcium and magnesium complied with the national and international standards set by Malawi Bureau of Standards (MBS) and World Health Organization (WHO). As regards to microbiological characteristics, it was revealed that water from three sources (B2, B3 and B4) was contaminated with Escherichia coli and faecal coliforms.

Keenjhar Lake is the main source of drinking water for the metropolitan city of Karachi. The release of untreated wastewater from Kotri industrial area and other sources have made the lake water polluted. This study was subjected to determine the impacts of such pollutant sources on the water quality of Keenjhar Lake. The study involves the analysis of water quality parameters of Keenjhar Lake and its Feeding source (KB Feeder). The sampling sites were selected based on the sources of contamination. The water samples are tested for physical, chemical and microbiological parameters. The result of water analysis indicates the contamination level of the lake is quite alarming for the sites of Kotri effluent and WAPDA colony where Total Dissolved Solids (TDS), Chloride and other ionic metals were quite higher in concentration than other sites. These sites are also contaminated with Fluoride and Arsenic which are carcinogenic elements. The study reveals that the contamination level of feeding source is causing big non-reversible damage to the lake if continued to be uncontrolled. This contamination is mainly due to the release of toxic metals and ions in the KB feeder caused by human carelessness.

Quality Status

The present investigation was conducted to assess the water quality status of the river Buriganga. Water samples were collected from three selected stations in wet (June-August) and dry (November-January) seasons during the years 2017 and 2018. Temperature and Dissolved Oxygen (DO) of water varied from 22.80 to 31.40 °C and 0.22 to 2.74 mg/L, respectively. Electrical conductivity of water varied from 180 to 598 μS/cm while pH ranged from 7.61 to 8.97. This study showed that temperature, DO and Fe were higher in wet season than in the dry season, whereas pH, conductivity and phosphate were higher in dry season than in the wet season. But manganese did not vary in different seasons. It is found that the differences of water quality parameters were significant in seasons (p<0.05) except for Fe and insignificant for stations (p>0.05) except for DO. The results reveal that there were significant differences between sampling seasons (wet and dry) (p<0.05) except for temperature and manganese. A significant correlation (p<0.01) was also found among temperature and other parameters viz. DO, conductivity, pH, phosphate. According to the result obtained in the present study, it may be said that the water quality of the river Buriganga is not acceptable to declare the river-ecosystem as a sound one ecologically.J.

The study was conducted to determine the status of physico-chemical parameters of the Brahmaputra river water in Sherpur district and also to assess the monthly variation of the river water. To perform the study the samples were collected from five different stations during the period of December 2013 to May 2014. Various water quality parameters such as transparency, temperature, electrical conductivity (EC), total dissolved solids (TDS), pH, dissolved oxygen (DO), biochemical oxygen demand (BOD), hardness and alkalinity were examined. The study revealed that a slightly variation in water quality at different stations of the river. The mean value of transparency (42.21 cm), temperature (23.38oC), EC (351.12 ?s/cm), TDS (178.54 mg/l), pH (7.75), DO (4.47 mg/l), BOD (1.02 mg/l), hardness (82.36 mg/l) and alkalinity (98.63 mg/l) showed that the present status of the Brahmaputra river water is suitable for all aquatic lives, domestic and agricultural uses. Although the overall status of the river water quality is suitable, degradation was detected in few points which might be due to anthropogenic activities, especially the direct discharge of domestic effluents into river. Thus, necessary initiatives should be taken against such anthropogenic activities to maintain the overall water quality of the Brahmaputra river for its sustainable use.Bangladesh J. Sci. Res. 28(1): 35-41, June-2015
