Comparison Of The Results

High demand for clean water in Banjarmasin requires PDAM Bandarmasih to do some developments, but its efforts are hindered by the water quality of raw water to be processed. It is therefore necessary to conduct a study on the water quality of raw water sources of PDAM Bandarmasih, especially during dry season. Water quality testing was carried out by performing direct experiments in the field and in the laboratory with 7 criteria including water temperature, electrical conductivity, total dissolved solids, pH, turbidity, salinity and dissolved oxygen that were compared with the criteria of water class B (water that can be used as the raw water for drinking water), on the basis of the Regulation of the Minister of Health of the Indonesia Republic No. 492/Menkes/PER/IV/2010. Based on the analyses of water quality in the field and in the laboratory from 4 intakes namely Sungai Tabuk, Pematang Panjang, Sungai Lulut and Sungai Bilu, and the comparison of the results with the test results of water quality of the samples from PDAM taken in dry season, indicated that the amount of salt content (salinity) in two intakes, Sungai Lulut and Sungai Bilu was so high that the production of clean water from both intakes was stopped temporarily during the dry season. The service for clean water was therefore provided only at the intakes of Sungai Tabuk and Pematang Panjang during dry season, resulting in some reduction in distribution to some areas in Banjarmasin.

ABSTRACTThis research was conducted to determine the status of Lake Toba water quality in the area of Toba Samosir (Tobasa) Regency and the feasibility of its use. This study revealed that BOD, COD, iron and free Cl2 of Lake Toba Tobasa regency exceed water quality criteria for Class I and Class II based on Governor Decree No. 1 Year 2009 on Raw water quality of Lake Toba in North Sumatera. High COD and BOD values imply that Lake Toba water was polluted by organic matter presumably originated from floating net cages (KJA), while free Cl2 is thought to originate from domestic waste activities in Parapat City and its surroundings. In general, it was concluded that the water of Lake Toba in the Tobasa Regency did not meet the criteria for clean water and water tourism.Keywords: Lake Toba, raw water, pollution, water qualityABSTRAKPenelitian ini dilakukan untuk mengetahui kualitas air Danau Toba wilayah Kabupaten Toba Samosir (Tobasa) dan kelayakan peruntukannya. Penelitian ini mengungkapkan bahwa air Danau Toba wilayah Kabupaten Tobasa memiliki BOD, COD dan konsentrasi besi dan Cl2 bebas melebihi kriteria mutu air Kelas I dan Kelas II pada Peraturan Gubernur Sumatra Utara No 1 Tahun 2009. Tingginya nilai COD dan BOD mengisyaratkan bahwa perairan Danau Toba tercemar oleh bahan organik yang diduga berasal keramba jaring apung (KJA), sedangkan Cl2 bebas diduga berasal dari limbah domestik kegiatan Kota Parapat dan sekitarnya. Secara umum disimpulkan bahwa air Danau Toba di wilayah Kabupaten Tobasa tidak/belum memenuhi kriteria untuk air baku air minum  dan wisata air.Kata kunci: danau Toba, bahan baku air, pencemaran, baku mutu

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: The Decrease in the Number of Coli Bacteria in Water of Martapura River Using The Husk Charcoal Filter. The habits of the people along the Martapura river, defecates into the river, causing the river water polluted by Coli bacteria that be able to cause disease. Water treatment is required to improve the water quality of the Martapura river, one of them is using "the husk charcoal filter " to obtain clean water that meets health requirements. This study aimed to analyze the effectiveness of the husk charcoal filter, and determine the thickness of the filter were most effective to decrease the number of coli bacteria in water of Martapura river. In this design, was performed the initial measurements (pretest), performed the treatment and performed the second measurement (posttest), so it could be seen the effectiveness of the treatment. The "husk charcoal filter" was effective to Decrease the Number of Coli Bacteria in the water of Martapura river as much as 69,2% - 99,3%. However, a decrease in the number of coli bacteria still above the standards required by the Water Quality Standard class B, after filtration. Because it still found much bacteria after filtering, it is advisable to boil water to boiling before consumption, because heating is the most effective way to kill microbial pathogens that be able to cause disease. Keywords: Water of Martapura River; coli bacteria; the husk charcoal filter.

Abstract The quality of drinking water source remains as a major concern in areas of developing and underdeveloped countries worldwide. The treatment and supply of drinking water in Rwanda are carried out by Water and Sanitation Corporation, a state-owned public company. However, it is not able to supply water to all households. Consequently, the non-serviced households depend on natural water sources, like springs, to meet their water requirements. Nevertheless, the water quality in these springs is scarcely known. Therefore, this study assessed and compared metal elements in drinking water sources in the dry and rainy seasons in 2017 using the contamination degree, metal index, and geographic information systems to reveal the spatial distribution of water quality within the considered water sources of springs in Rwanda. The samples were collected monthly from nine water sources of springs and the measured elements are aluminium, calcium, copper, iron, manganese, and zinc. The metal index indicated that during the dry season and rainy season, the sites of Kibungo (1.10 and 1.26) and Kinigi (1.01 and 1.54) have assessed a metal index which is higher than 1. Thus, the water quality of those sites was getting the threshold of warning. The analysis indicated that pollutants are easily transported into water bodies during the rainy season in urban and rural areas to a greater extent than during the dry season .

The need for clean water in big cities is very dependent on water supply by water companies (PDAM). The increasing demand for clean water in big cities is proportional to the increasing of number population and industry, but not comparable to the clean water supply and quality of raw water available. PDAM has made various efforts to improve the quality of clean water services to the community. One of the effort is to improve the performance of water treatment plant (WTP). To support the improvement of the performance of WTP, required water quality monitoring at the intake location in use. This paper discusses the online and realtime water quality monitoring at the water intake location using a multi-probe digital sensor and GSM technology. This observation data is used as a comparative data analysis of laboratory data on raw water source PDAM Taman Kota (Cengkareng Drain). Keywords: air baku air minum, intake PDAM Taman Kota Cengkareng Drain, pemantuan kualitas air, multi probe digital sensor, teknologi online monitoring, Water Treatment Plant
