Water Quality Standards

 This study aims to determine the latest water quality conditions in terms of physical, chemical and biological properties in the DAS Bugis and DAS Wain. Analysis of water sample was conducted at the Water Quality Laboratory of the Department of Aquatic Resources and Fisheries and Marine Sciences, Mulawarman University, Samarinda. Data analysis refers to the Water Quality Standards based on East Kalimantan Regional Government Regulation No. 02/2011 about Management of Water Quality and Water Pollution Control. The results showed that the parameters of temperature, colour, TSS, TDS, BOD5, SO4 and NO3 were included in the Class I water quality standards that can be used as drinking water or for other consumption purposes. COD parameters (in the Right River Basin), DO and NH3 (in the River Basin) were included in Class II water quality standards, which can be used for water recreation infrastructure / facilities, freshwater fish farming, animal husbandry and plants irrigation. The pH parameters in the DAS Bugis were included in class IV water quality standards that can only be used to irrigate plants. Pollutant loads that contribute a lot to enter were agricultural and agricultural waste and domestic waste originating from community forest areas.

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.

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.

Faecal coliforms are indicative bacteria of fecal contamination. If the bacteria are found in the waters so that the waters has been polluted and can not be used as a source of drinking  water.  The  research  has  been  conducted  from April  to  June  2014  at  Sari Residence Housing which located in Siak riverbanks by using survey method. Densitydata of water coliform bacteria the preliminary test and assertion test in the laboratory according to SNI 2897-2008. Data analysis is using ANOVA statistics and compared with the water quality standards according to the Indonesian Government Regulation No. 82 year 2001 on the Management of Water Quality and Water Pollution ControlClass I and Class II. The results showed that the density of coliform bacteria in the Siak River (around Sari Residence Housing Pekanbaru city) ranged between 11267-15650jml/ 100mL and pass the drinking water quality standards and require special handlingfor the use of water. Siak River water (around Sari Residence Housing Pekanbaru city)not feasible for consumption according to PP 82 year 2001 class I and II on the drinkingwater requirements of 1000 jml/100mL and 5000 jml/100m

Clean water is an unlimited and sustainable need that must be fulfilled every day and meet an appropriate standard in terms of quantity and quality. The research objective in this study was to analyze the quality of water in thirty freshwater springs and twenty four brackish springs in the karst area of Buton Tengah Regency to achieve sustainable water resource management. Data on the quality of freshwater springs and brackish water springs chemically and biologically have been analyzed in the biology laboratory of FMIPA Universitas Halu Oleo, then the results are compared with the standards for water quality contained in the regulations of the Minister of Health and Government Regulation of the Republic of Indonesia. The results showed that the freshwater springs in Talaga Raya District exceeded the water quality standards for hardness parameter, while the brackish springs in Mawasangka Tengah, Mawasangka Timur, Lakudo, and Mawasangka Districts has exceeded the water quality standards for parameters of total dissolved solids, hardness, and chloride. However, these parameters are relatively easy to overcome so that the use of freshwater springs can qualify as drinking water, while the use of brackish springs should be used to meet domestic non-drinking water needs.

Abstract Water is one of the primary needs of every living creature. With the increase in population, the need for water continues to increase. The declining water quality caused by human activities is one of the world’s concerns. This study examines river water quality status in the gold mining area in the downstream of Krueng Kluet sub-watershed. The method used to determine the level of river water pollution is based on the Decree of Minister of Environment Number 115 the Year 2003, which uses class 1 water quality standards according to Government Regulation of The Republic of Indonesia Number 82 the Year. The results show that river water in the study area is in the category that is not polluted or fulfills water quality standards for drinking water and daily needs.

Water Quality Models

Abstract This paper describes a method of applying probabilistic DO (dissolved oxygen) and BOD (biochemical oxygen demand) standards in river basin water quality models. Maximum likelihood estimators for the DO and BOD concentrations variances for each reach are used to obtain a lower bound for BOD so that the probability of violating specified DO and BOD standards is less than Θ per cent in any reach. These boundary values for DO and BOD concentrations are incorporated into a nonlinear water quality optimization model for finding the minimum cost set of wastewater treatment plant efficiencies required to meet DO and BOD standards. The method also provides the minimum DO concentration and the maximum BOD concentration which may be expected to occur 1-Θ of the time for any reach.
