The quality of water is crucial for the qualification of river beaches. The Cávado River watershed (Northern Portugal) contains five river beaches with a regular and specific mandatory monitorization. The main subject of this research is the evaluation of spatial and temporal water microbiological and physicochemical parameters to assess the water quality improvement and consequently watershed management. The results of monitoring surface water, considering microbiological parameters from the five river beaches (2015/19), and physicochemical parameters from three water points along the Cávado River (2018/19) were considered. The river beaches located upstream of the town of Braga has an “excellent” and “good” quality, while the river beach located downstream shows a lower water quality. The physicochemical water results indicated that there is a progressive degradation of water quality from upstream to downstream of the river, which is associated with the influence of domestic and industrial activities. To improve water quality, continuous monitoring will be necessary, with the implementation of adequate awareness-raising programs and strategic water quality management by the population and local agents.

The Mourão River basin is located on the central western region of the Paraná State – Brazil, between coordinates 23º 44’ - 24º 25 South latitude and 52º 12’ - 52º 30’ West longitude, between 270 and 820 m above sea level, and 1,648.21 km2 drainage area. Water quality was evaluated by monitoring physical, chemical and microbiological parameters. Monthly samplings were performed for a year at five sites in the basin for analysis of: pH, temperature, dissolved oxygen, biochemical oxygen demand, total nitrogen, ammoniacal nitrogen, nitrite, nitrate, total phosphorus, turbidity, total solids, volatile solids and fecal coliforms. The results of the evaluated parameters showed higher values than the limits set by CONAMA Resolution 357 from 2005 for Class 2 in some samples. The Water Quality Index (WQI) indicated that 72% of samples had average quality and 28% had good quality for the Mourão River basin. Higher values of WQI were observed after rainfall period with median of 75 compared to the dry period with median of 62. The source of the Mourão River is contaminated with fecal coliforms, evidencing the real need to treat sewage in rural areas.

The present study was undertaken in order to determine the quality of indoor pool waters in hotels along the Croatian coast. We wanted to assess the risks of exposure to microbial and chemical contaminants and find out if training pool operators to use a quality assurance system, that we developed, influenced hygienic conditions and water quality in swimming pools or not. The samples were analysed for free chlorine, pH and several microbiological indicators according to standard laboratory methodologies. Of 1,329 samples tested, 276 were found to be unacceptable either by chemical (148) or microbiological parameters (128). After training, the proportion of unacceptable samples dropped by 23.5%, mostly according to the free chlorine values. According to our results, most of the microbiologically unacceptable samples had chlorine levels within the recommended range but their pH values were too high. A free chlorine level below 0.2 mg/L was found in 106 (82.8%) microbiologically unacceptable samples suggesting the need for maintaining the lower limit at least above 0.2 mg/L in order to reduce microbial risks to a more acceptable level. This measure combined with training of pool operators might result in reduced health risks in pool waters.

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.

The objective was to characterize water quality for a section of the Grijalva River and its tributaries, for rainy and dry season in the border of the States of Chiapas and Tabasco. 23 physical, chemical, and microbiological parameters as well as contaminants were determined and compared with the Mexican norm NOM-127-SSA1-1994 which establishes water quality maximum permissible limits for use and human consumption and with the water quality classi cation scale proposed by the Comisión Nacional del Agua. Water quality of the Grijalva River in the studied section and tributaries, also locally named Almandros river, decreases as it descends to more populated areas of Tabasco. Water turbidity and high levels of coliforms and Escherichia are the main problems associated with the rivers of the studied area, even in water sources destined for human consumption. Other studied parameters have acceptable water quality mainly during the dry season, except for Mercury, which showed higher levels than the recommended by the norm in all sampling sites. The need to further study presence of Mercury in the Grijalva River basin is suggested.

Abstract DKI Jakarta is one of the provinces with the highest flood risk in Indonesia. 13 rivers divide Jakarta from upstream to downstream, one of which is the Ciliwung River. However, at this time, the Ciliwung River was asked to be one of the dirtiest rivers in the world. The purpose of this study was to determine the levels of physical parameters (TSS), chemical parameters (BOD, COD, Total Phosphate), and microbiological parameters (Total Coliform, Fecal Coliform) in the Ciliwung River, along with the potential health disaster risks from various parameters studied based on literature review. The method used is descriptive quantitative with secondary data sources in the form of monitoring data on the water quality of the Ciliwung River, which was carried out for four periods in April, June, July and August at 21 points spread along with upstream to downstream. The results showed that the physical, chemical and microbiological parameters had passed the specified standard thresholds and had the potential for a public health disaster due to exposure to organic compounds and microorganisms in the Ciliwung River. Further efforts related to disaster need to be carried out in a Penta helix manner so that disaster risk reduction efforts can be carried out as a whole.

ABSTRACTThe provision of clean water in the Class 1 Surabaya Port Health Office is supervised in accordance with the existing regulations to identify sources that could potentially cause pollution and prevent the occurrence of illness caused by unstandardized water quality and unsafe water supply. This study aimed to describe the implementation of clean water supply supervision in the Class 1 Surabaya Port Health Office in the Juanda Airport working area, Surabaya. This was an observational study which analysis was descriptive in nature. The clean water was tested for physical, chemical, and microbiological parameters, and the results showed that the water quality was in accordance with the Regulation of the Indonesian Ministry of Health No. 416 of 1990 about the Terms and Monitoring of Water Quality. However, the result from the simple chemical inspection test of the water showed that it did not fulfil health standards i.e., the residual chlorine score not equal to 0 (zero). It is suggested that more attention and supervision are conducted by water management authorities to ensure the standard residual chlorine level of 0 (zero). Additionally, expired reagents or reagents that have already changed color should not be used as it will affect the parameters tested. Keywords: Quality of clean water, clean water supply facilities, water sampling process
