Sei Siarti Village, Panai Tengah District, Labuhanbatu Regency have problems in the form of limited clean water sources that are suitable for use. There are several potentials including peat water, drilled well water, and Barumun river water that crosses the village. The condition of peat water that does not comply with quality standards for water that is fit for consumption has a brownish color, high acidity, and the organic matter contained in peat water is high enough to cause an odor. The well water has a salty taste (high salt content) so that what has the potential is Barumun river water even though it has a cloudy color. The method used to purify cloudy river water is through the processes of coagulation (deposition), filtration (filtering), absorption (absorption), and adsorption (ion exchange). This water purifier is made using 2 tubes filled with silica sand, MGS, activated carbon, and zeolite sand so that the water produced is clear and fit for consumption and can be utilized by the surrounding community. The results obtained from this water purification are water that does not have a smell, taste, and is clear in color so that it is suitable for use by the surrounding community

Heavy metal in river come mainly from naturally occurring geochemical materials. However, human activities has enhanced concentration of heavy metal such as coal mine in the case of pollution in Lematang River. The high suspended solid loads in the river can remove most soluble metals from the water and trapped them in the bottom sediment. Freshwater molluscs were collected 3 sampling site, Lahat (ST1) as reference site, and polluted rivers of West Merapi (ST2) and East Merapi (ST2). Freshwater molluscs were analysed for the heavy metal contents in tissue. Relationships of the heavy metal in sediment to the heavy metal content in molluscs was performed using SPSS 24. Thiara scabra was the most abundant taxa in sampling area. Concentration of Fe and Mn in sediment has no significant effect on the Fe content in mollusc tissues. Molluscs appeared to more sensitive to higher Mn content. This study did not clearly show molluscs as a bioaccumulator for metal. Nonetheless, Thiara scabra were common, abundant, easily sampled and it is a useful choice as bioindicator in Lematang river for future study.

The study was conducted to investigate the iron (Fe) contamination in groundwater at Tangail municipality during the period from January to June 2011. Groundwater samples were collected from 18 locations, where 15 were tube-wells, 2 deep tube-wells and 1 pump. The result of the study showed that the highest level of Fe (24.50 mg/l) was found at Dewla north, while the lowest level (1.03 mg/l) was recorded from Bepari para. The highest and lowest amount of Fe was found in ward 1 and 4, respectively. The results were compared with the Bangladesh drinking water quality standards as well as with the international standards. In Bangladesh, permissible limit of Fe is 0.3-1.0 mg/l, whereas WHO standard level is 0.3 mg/l. All the samples were exceeded the standard levels of Fe, whereas ward 1, 2 and 7 were worstly affected. The study also reveal that the availability of Fe does not depend on the type of water sources, but it depends on the aquifers or water table. If the aquifer contains Fe, then the tube-well water will contain Fe or vice versa. These higher Fe concentrations found in the study area may be harmful for those families who are consuming the water from these sources on regular basis. Thus, to overcome this problem the consumers should not drink these higher amounts of Fe, and they should find other sources or replace the tube-well or treat the water before drinking and other domestic and household purposes.DOI: http://dx.doi.org/10.3329/jesnr.v6i1.22051 J.

[ID] Di kabupaten Kepulauan Meranti khususnya Masyarakat Kecamatan Rangsang pada umumnya menggunakan air hujan dan air Sungai sebagai kebutuhan air bersih sehari-hari, jika pada musim kemarau masyarakat pada umumnya sulit mendapatkan air bersih. Dengan adanya Sarana penyediaan air bersih yang dibangun oleh pemerintahan Kabupaten Kepulauan Meranti yaitu Sarana Penyediaan Air Minum (SPAM) ini sangat membantu dalam memenuhi kebutuhan air bersih masyarakat. Dilihat secara warna, air bersih yang di produksi oleh SPAM Kecamatan Rangsang berwarna kecoklatan, dilihat dari segi warna hampir sama dengan air baku SPAM Kecamatan Rangsang tersebut. Pada SPAM Kecamatan Rangsang ini proses pengolahan air bersih menggunakan metode koagulasi, flokulasi, sedimentasi dan filtrasi. Peneliti mencoba meninjau apakah proses-proses pengolahannya telah sesuai dengan metode yang telah di terapkan, mengetahui kualitas air bersih yang dihasilkan serta mengetahui masalah-masalah yang terdapat pada SPAM Kecamatan Rangsang tersebut. Dari hasil penelitian yang dilakukan untuk pemprosesan air bersih adanya proses yang tidak dilakukan yaitu tidak dilakukan pembubuhan zat Koagulan,  hal tersebut dikarenakan zat-zat Koagulan yang ada di SPAM Kecamatan Rangsang tidak tersedia untuk saat ini. Untuk kualitas air bersih yang di produksi SPAM Kecamatan Rangsang tidak memenuhi standar kualitas air bersih berdasarkan peraturan menteri kesehatan nomor 416 tahun 1990 tentang “syarat-syarat dan pengawasan kualitas air” yaitu air bersih sesuai dengan hasil uji laboratorium dinas kesahatan kota pekanbaru pada tanggal 13 November 2017, serta terdapat beberapa alat yang tidak beroperasi, yaitu rusaknya 1 buah pompa Intake  dan 1 buah pompa distribusi [EN] In the Meranti Islands district, especially in the Subdistrict of Rangsang District, the people generally use rain water and river water as their daily clean water needs, if in the dry season the community in general is difficult to get clean water. With the availability of clean water facilities built by the government of the Meranti Islands Regency, the Drinking Water Supply Facility (SPAM) is very helpful in meeting the community's clean water needs. Viewed in color, the clean water produced by SPAM in the District of Rangsang is brownish in color, in terms of color it is almost the same as the SPAM raw water in the District of Rangsang. At SPAM in the District of Rangsang, the process of treating clean water uses the methods of coagulation, flocculation, sedimentation and filtration. Researchers try to review whether the treatment processes are in accordance with the methods that have been applied, find out the quality of clean water produced and find out the problems found in the SPB Subdistrict. From the results of research conducted for the processing of clean water there is a process that is not done that is not done by adding coagulant substances, it is because the coagulant substances in SPAM Subdistrict, Rangsang District are not available at this time. For the quality of clean water produced by SPAM in the Subdistrict of Rangsang District, it does not meet clean water quality standards based on the Minister of Health Regulation number 416 of 1990 concerning "requirements and quality control of water", which is clean water in accordance with the results of laboratory tests on the city health office Pekanbaru on November 13 2017, and there are some tools that are not operating, namely the damage of 1 Intake pump and 1 distribution pump.

<i>Abstract</i>.—A 37-year series of standardized fish assessments in the Scioto River (Ohio, USA) since 1979 coupled with historical information documents a near complete recovery from heavily polluted conditions in the late 19th and early to mid-20th centuries. Nearly 100 fish species were extirpated downstream from the city of Columbus (Ohio, USA) by sewage and industrial pollution. The 1972 amendments to the Federal Water Pollution Control Act (Clean Water Act) mandated the control of sewage and industrial pollution. Reductions in loadings of untreated or poorly treated sewage were incremental. Full recovery to near-prepollution composition and abundance took more than two decades after advanced wastewater treatment was achieved. Unpolluted tributaries served as recolonization sources for populations of extirpated species. These positive changes extended across all fish assemblage members as evidenced by increased values of the Ohio index of biotic integrity; modified index of well-being; native species richness, density, and biomass; and the reduced incidence of external anomalies on fish. These restoration successes and their documentation were facilitated by the Clean Water Act that set forth the goals for water quality standards and treatment technology for reducing water pollution and conducting baseline and follow-up monitoring. An important lesson learned was that serious doubts that existed in the 1970s about the feasibility of advanced wastewater treatment technology and the attainability of water quality standards in an effluent dominated river were completely erased by the demonstrated improvements in the fish and macroinvertebrate assemblages in the Scioto River. The extent of improvements in recreational opportunities have tracked that of the biota by an increased use for fishing, canoeing, kayaking, and related forms of recreation. However, maintaining these improvements will require continuation of high levels of wastewater treatment and water quality standards. A growing human population that is forecast to increase by one-half million persons by 2050 makes maintaining the currently high levels of biological integrity a continuing challenge. Given the lessons learned with the mosaic of stressors in the Scioto River over the past 150 years, we believe this challenge can be met successfully.
