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.

Water quality is one of the crucial parameters in monitoring and evaluating watersheds. A large number of parameters causes the monitoring and evaluation of watershed performance to be less efficient and costly. This study aims to determine the main parameters as a method of simplifying water quality observation parameters by producing equations that can be used to predict the level of pollution of a non-point source pollutant (watershed). A sampling of surface water was carried out by purposive sampling at several outlets located in the Brantas and Upper Solo watersheds. The research parameters analysed were: TSS, TDS, BOD, COD, Phenol, Free Chlorineine, Sulfide, Arsenic, Fe, Pb, Phosphate, Nitrate, Nitrite, Detergent, Turbidity and E. Coli. The results of the analysis of water quality are used to calculate the value of the Pollution Index (PI) according to the Decree of the Minister of Environment No. 115 of 2003 and to determine the class of water quality standards that refer to Class III water quality standards, in Government Regulation No.82 of 2001. The analysis showed that all samples were at mild to moderate pollution levels, and did not meet class III water quality standards. Multiple regression analysis produced two equations, namely: Model 1: PI = 3.952 + 91.668 Phenol and Model 2: PI = 3.086 + 80.167 Phenol + 0.152 BOD, with R squared values of 53% and 69.9% with a confidence level of 0.005. Thus the prediction of pollution levels of similar watershed can be made only by using the two most influential parameters namely phenol and/or BOD alone.

 Sirau River is one of the rivers in the Barito Timur Regency which flows through the Dusun Timur District. Sirau River water is used as raw material for regional water companies (PDAM) and is used by communities around the river to meet the needs of other daily life such as MCK and other uses and is also used as a landfill, domestic wastewater and waste water mining and plantation activities both directly and indirectly. This study aims to analyze the status of pollution of the Sirau river through the approach of the pollution index value, assess the quality of the Sirau River water and identify the source of pollutants entering the Sirau River. The results showed that in general the water quality of the Sirau River for pH, COD, BOD, Fe, and Mn parameters exceeds the water quality standard namely Government Regulation No. 82 of 2001 class II concerning Water Quality Management and Water Pollution Control, the main source of pollutants comes from residential domestic waste, coal mining activities and dry leaves that fall into river streams. Sirau river water quality from upstream to downstream based on river water quality analysis using the pollution index method shows that water quality has decreased where the river conditions are generally mildly polluted. The quality of lightly polluted Sirau river water cannot be utilized in accordance with the designation of class II water based on Government Regulation No. 82 of 2001 concerning Management of Water Quality and Water Pollution Control.

<p>Grenjeng River is one of the irrigation water resources which is currently polluted by waste from industrial, livestock and domestic activities. This study aims to assess the quality and index of water pollution based on physical-chemical and biological parameters in the Grenjeng River, Boyolali Regency. Sampling of river water was carried out in dry and rainy seasons which were taken at three observation stations (upstream, middle stream and downstream). Results from laboratory analysis were compared with water quality standards according to Government Regulation No.82/2001, and quality status was based on the Pollution Index method in accordance with the attachment to Minister of Environment Decree No.115/2003. This study shows that BOD of 53-5.7 mg L<sup>-1</sup>, COD of 49-510.5 mg L<sup>-1 </sup>and total coliforms of 540-2,400,000 mLin dry season have exceeded the quality standard water classes, while in rainy season total coliforms 24,000-240,000 mLhave exceeded the standard water for all water classes. The pollution index of the river water in dry season has reached polluted to extremely polluted levels and the index of the river water in rainy season has reached moderately polluted to polluted levels. This condition shows that the practice of dumping waste into river bodies can directly affect river water quality. The irrigation water source for agricultural must comply with irrigation water quality standards so that is suitable as irrigation water for plants. Environmentally friendly approach is needed to prevent worse pollution, which is done by increasing public awareness and business actors in managing liquid waste by making the integrated wastewater treatment system.</p>

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.

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.

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.

The lack of clean water distribution by local water service (PDAM) of Palangka Raya city is the major reason for people around the final processing site/landfill (Tempat Pemrosesan Akhir) at Km 14 to use groundwater for their daily life. The landfill may cause pollution over groundwater known as leachate, which commonly unnoticed by its users. This study aims at assessing the quality of groundwater in that area. The groundwater was taken at different distances from the site in three rainless-days. The physical, chemical and biology parameters of groundwater are observed in the field (in situ) and analyzed in the laboratory, refers to water quality standard of Class I, according to Government Regulation No. 82 of 2001 and Minister of Health Regulation No. 32 of 2017. Public opinion on that issue is cached through interview. The results showed that the groundwater around the landfill in three rainless-days was harmless to be consumed as drinking water, and did not exceed the water quality standards stipulated by government in term of odorless, tasteless, and colorless. Some indicators also show that the groundwater meets the specified quality standards, i.e. TDS (17-68.14 mg/L), DHL (17,15-69.39 ?s), turbidity (0.11-2.50 mg/L), iron (0.227-0.71 mg/L), manganese (<0.0123-0.02 mg/L), coliform (<1.8-280 MPN/100 ml), while Pb and H2S were not detected. From community side, there are no any health complaints arise as long as they use the water.
