The high water pollution index causes a decrease in water quality so that it can interfere with the health of living things. In order to overcome this, the government has tried to monitor water quality whose results can be known by the community. However, information disclosure and ease of accessing information are felt to be lacking. This study aims to present information about the quality status of river water and its relatively up-to-date and easily accessed by the public online. The storet method is used to determine the status of river water quality with seven parameters: temperature, EC, TDS, pH, DO, BOD and E.coli. The features provided will be explained in the results and discussion presented in several UML diagrams. In order to get results that match user expectations, this system was developed with extreme programming system development methods.

The paper analyzes the water quality of hydrological resources in the wider area of Tara National Park (NP Tara) in Serbia and the opinions of the local community and the national park visitors about the grade of the possible damage. The pollution level of the Drina River at the Bajina Bašta hydrological station was analyzed using the Water Pollution Index. The results showed that water quality corresponded to classes II (clean water) or III (moderately polluted water) and revealed the presence of organic pollution. In addition, using a survey combined with field research, the perceptions of local inhabitants and national park visitors related to environmental pollution were analyzed. The community believed that tourism does not cause significant damage to the environment. However, the older and more educated groups of residents and visitors had a more critical perception of the environmental impact of tourism. The results also indicated that the perceptions of visitors were mostly in agreement with measured water quality in the Drina River. The findings of this study have important implications for the management of protected areas and future policies related to national parks.

Abstract The Santiago River is one of Mexico's most polluted waterways and evaluating its surface water quality during the COVID-19 outbreak is critical to assessing the changes and improvements, if any, from the nationwide lockdown (April-May 2020). Hence, the data for 12 water quality parameters from 13 sampling stations during April-May 2020 (lockdown) were compared with the levels for the same period of 2019 (pre-lockdown) and with the same interval of previous eleven-years (2009-2019). The values of BOD (14%), COD (29%), TSS (7%), f. coli (31%), t. coli (14%) and Pb (20%) declined, while pH, EC, turbidity, total nitrogen and As enhanced by 0.3-21% during the lockdown compared to the pre-lockdown period suggesting decrements of organic load in the river due to the temporary closure of industrial and commercial activities. An eleven-year comparison estimated the reduction of pH, TSS, COD, total nitrogen and Pb by 1-38%. The analysis of water quality index estimates showed short-term improvements of river water quality in the lockdown period, compared to pre-lockdown and eleven-year trend as well as indicated very poor quality of the river. The contamination sources identified by factor analysis were mainly related to untreated domestic sewage, industrial wastewaters and agriculture effluents influencing the river water quality. Overall, our findings demonstrated positive responses of COVID-19 imposed lockdown on water quality of the Santiago River during the study period, providing a foundation for the government policy makers to identify the sources of pollution, to better design environmental policies and plans for water quality improvements.

Abstract This research aims at using a combined water quality index (WQI) and pollution index (PI) to assess and characterize river water quality of Cau River which is one of the longest rivers in the north of Vietnam. Five different water quality and water pollution indices were used including the Water Quality Index (WQI), Comprehensive Pollution Index (CPI), Organic Pollution Index (OPI), Eutrophication Index (EI), and Trace Metal Pollution Index (TPI). The combined water pollution indices show more serious pollution towards the river downstream. In particular, CPI and OPI reveal a high risk of eutrophication. Cluster analysis was applied to classify water monitoring points into different quality groups in order to provide a better understanding of the water status in the river. This study indicates that a combined water quality analysis could be an option for decision making water use purposes while its single index shows the current situation of water quality.

Research has been conducted to determine the quality of shallow groundwater (dug-wells and shallow bore-wells) and the local communities opinions around the landfill Suwung. The method of determining the station was done by purposive sampling, where the station sampling was determined by selecting a place which was expected to represent the whole area.Water sampling of dug-wells was conducted by using a water sampler and the shallow bore-wells using a 2-liter bottle. Data was analyzed by descriptive comparative referenceto class I water quality of the Bali Governor Regulation No.8 of 2007. The public opinion data was obtained by using aquesioner filled by respondents who have and use wells and shallow bore wells for their daily needsand it was analyzed by using frequency distribution tables.The results showed that the quality of shallow groundwater (dug-wells and shallow bore-wells) did not meet water quality standards in accordance with the rules of the class defined in the Governor of Bali Regulation No. 8 of 2007. The water pollution index (PI) of dug-wells at a distance of 1-400 meters was in hearily polluted category, while water fromshallow bore-wells drilled at a distance of 1-200 meters was in the category of hearily polluted and at a distance of 201-400 meters was in the category of medium polluted.There was an increasing range of groundwater quality deterioration in 1997, 2008 and 2014. In 1997, contaminated shallow groundwater has occured at a distance of 80 meters, while in 2008, the pollution has occurred up to a distance of 375 meters and in the year of 2014 the contamination occurred from a distance of 1 meter to 400 meters. The average of score Pollution Index (PI) of Water wells in the year of 2008 amounted to 14.55, while in 2014 up to 15.44. It is estimated that the water quality of dug-wells and bore-wells will meet the quality standards in accordance with the value of the pollution index at a distance of over 5000 meters and 750 meters of the Suwung landfill waste.Most of the respondents who live in the vicinity Suwung landfill waste tend to give an opinion that the shallow groundwater (dug-wells and shallow bore-wells) has decreased quality as drinking water. Approximately 75% of respondents thought that the well water in their environment has been reduced in quality.

The main objective of the research is a complex assessment of the actual ecological status of Salgir River waters based on several methods: visual survey of the watercourse as well as studying spatial and temporal transformation of water quality and determining the degree of water pollution by means of an integral criterion –water pollution index (IES) and bioassay techniques carried on seeds of two test crops (cress salad and wheat), and also zoning a watercourse according to several criteria. The assessment found a tendency to increasing degradation of water quality due to the increase of the anthropogenic load (increase in water abstracted from the river). The typical pollutants in the Salgir river are petroleum products, phosphates, lead, copper, biological oxygen uptake (BOU5). Phosphate content is in the range of 5.5–27.5, lead – 3.06–6.67, copper –1.02–4.52 MPC. The most powerful source of pollution of the river is the treatment facilities of Simferopol. The results of this comprehensive study made it possible not only to reflect the real situation at the water facility, but also to highlight sections of the river where a set of measures aimed at reducing/preventing the consequences of anthropogenic impact should be carried out as a priority.

Water Pollution Index

The problems of drinking water quality have been considered in some settlements of the Turkivskiy district of Lviv region, in particular concerning the content of Nitrogen compounds. 20 sources of decentralized water supply were investigated. It was found that the main hydrochemical indicators of water samples mainly met the requirements for the degree of contamination of hygienic classification of water bodies. At the same time, analyzing the samples for the presence of nitrogen compounds, it was found that in the tested samples: the content of nitrate ions fluctuated within 0,02 - 016 mg/dm3 (average annual values did not exceed the permissible value); the content of ammonium ions is in the range of 0.5-2.8 mg/dm3, which did not significantly exceed the maximum permissible value. At the time, analysis for NO3- showed an excess of acceptable values in almost all samples by 1.3 у 4.2 times. It was found that the amount of nitrates decreased with the transition from the alluvial aquifers to the indigenous ones, where the average content was 108.9 mg/dm3 and 86.8 mg/dm3, respectively. This is probably due to better protection of the bedrock from surface contamination, greater capacity of the corresponding aquifers and their deeper occurrence. According to the average value of the water pollution index for the nitrate group, the studied objects of decentralized water supply belong to the second class ‒ moderately contaminated. The correlation between the water pollution index by nitrate group and the population morbidity is calculated to be direct and sufficiently high (0.73). The most associated indicators of water quality are diseases of the circulatory system, blood and hematopoietic organs, digestive organs, endocrine and urogenital systems.

Abstract. Baru Barat River is a man made river for flood and irrigation control. This study aims to determine the effect of activities on the bank on Baru Barat River on the water quality. Identification of activities is carried out along the bank of river. Water quality parameters are compared with the Governor of Jakarta no. 582 year 2005. The status of water quality is determined using the Pollution Inde (PI). The activities around the Baru Barat River are settlements, officem workshop, schools, deales, food stall, laundry, shops, beauty salons, guesthouses and gas station. BOD concentration range from 8.4-43.7 mg/L with a quality standard of 10 mg/L and COD range from 16-99.2 mg/L with a quality standard of 20 mg/L. Concentration of BOD and COD that exceed of quality standard at almost all sampling ponts. The level of pollutionj in the Baru Barat River is moderate polluted. The main problem at Baru Barat River are the presence of several illegal waste point left from activities that eventually enter the river and the absence of waste water treatment. The concept of community based must be implemented to waste management and communal wastewater treatment that are easy, inexpensive and integrated with the landscape.
