The Impact

Evaluation of water quality using different parameters is complex and not easy to understand as it is variable by variable discussion. Water quality index is a single value indicator used to evaluate and present the water quality to the public and the related management in precise and understandable manner. Measured values of eleven physico-chemical parameters namely, pH, TDS, TH, Cl-,NO3-,SO42-,HCO3-, Ca2+, Mg2+, Na+ and K+ were used to calculate WQI of six tanks in Tiptur taluk. The study was taken up to understand the impact of agriculture run off from the respective catchment area, domestic sewage input and human activities which contribute to pollution load. During the investigation period from December-2010 to November-2012, it was found that the overall water quality index of the studied tanks ranged from 46.72 to 92.22 indicating the quality ranging from good quality to very poor quality. Values of variables TDS, HCO3-, Na+ and K+exceeded their desirable limits of BIS/ICMR in Karadi, Halkurke and Honnavalli tanks which depend on rain water. Waters in these tanks were of moderately poor to very poor quality. Waters of Canal fed tanks were of good to moderately poor quality.

Quality Status

Sungai Jaing merupakan salah satu sungai yang melintas di Kabupaten Tabalong dengan panjang 39 km yang bermuara di Sungai Tabalong. DAS Jaing memiliki luas area ± 298 km2bagian dari DAS Barito di Kalimantan Selatan. Sungai Jaing diklasifikasi sebagai sungai kelas I (satu). Alih fungsi lahan cukup besar terjadi disekitar daerah aliran sungai jaing, bagi sektor pertambangan batubara, sektor migas, sektor industri, perkebunan dan pertanian. Banyaknya aktivitas ini menyebabkan sungai jaing berpotensi cukup besar mengalami penurunan kualitas. Pengamatan lapangan menunjukkan bahwa beberapa kegiatan berpotensi memasukkan unsur pencemar ke Sungai Jaing yang mana kemungkinan membuang limbah produksi secara langsung ataupun run off (limpasan) limbah produksi kedalam sungai. Tujuan penelitian ini adalah menganalisis kualitas Sungai Jaing melalui penentuan Status Mutu Air dari Sungai Jaing. Wilayah penelitian dilaksanakan di Sungai Jaing sejauh 39 Km di Kabupaten Tabalong, Kualitas air sungai diukur dan diamati pada 3 titik pengambilan sampel terhadap parameter fisika, kimia dan biologi. Analisis kualitas dan penentuan status mutu air menggunakan metode STORET dan metode indeks pencemaran. Hasilnya adalah (1) parameter DO, BOD, COD, Fecal coliform dan Total Coliform telah melebihi baku mutu air sungai Kelas I menurut Peraturan Gubernur Kalimantan Selatan                    No. 5 Tahun 2007 sehingga menyatakan kualitas air sungai jaing menurun ( 2) Terjadi pergeseran status mutu air sungai jaing dari hulu ke hilir yang ditandai dengan nilai STORET dan nilai indeks pencemaran (IP) yang cenderung semakin meningkat berdasarkan kriteria sungai menurut PP nomor 82 Tahun 2001. Nilai STORET sungai jaing adalah antara -108 sampai dengan -110 dengan status mutu Cemar Berat dan nilai indeks pencemaran (IP) berkisar antara 4,027 sampai dengan 4,173 yang menyatakan bahwa status mutu air sungai jaing adalah cemar ringan. Kata Kunci: Indeks polusi, kualitas air, metode STORET, status kualitas. Sungai Jaing is one of the rivers that flows in Tabalong District which has length of 39 km and empties into the Tabalong River. The Jaing watershed has an area of ± 298 km2 of the Barito watershed in South Kalimantan. This river is classified as class I (one) river. Several activities for the coal mining sector, oil and gas sector, industrial sector, plantation and agriculture considered to take over the land function widely surrounding the river. Those activities actually have a potential to reduce the water quality of the river. Field observations found pollutants which are likely to dispose of production waste directly or run off (run off) of production waste into the river. Hence, the purpose of this study was to analyze the quality of Sungai Jaing through determining the status of water quality from Sungai Jaing. The research area was carried out in Sungai Jaing as far as 39 Km in Tabalong District where river water quality was measured and observed at 3 sampling points based on physical, chemical and biological parameters. Quality analysis and determination of water quality status using the STORET method and pollution index method. The results are (1) the parameters of DO, BOD, COD, Fecal coliform and Total Coliform have exceeded Class I river water quality standards according to Governor of South Kalimantan Regulation No. 5 of 2007 stating that the quality of river water is decreasing (2) There is a shift of the water quality status of the Sungai Jaing from upstream to downstream which is characterized by the STORET value and pollution index value which tends to increase based on a river criteria according to PP number 82 of 2001. In addition, STORET value of river jaing is between -108 to -110 with the status of Heavy Pollution quality and the pollution index value (IP) ranges from 4,027 to 4,173 which states that water quality status of the Sungai Jaing is mild pollution.  Keywords : Water Quality, Quality Status, STORET Method, Pollution Index

Abstract Increasing anthropopressure affects natural ecosystems and may express itself in regional or spot contamination of water and soil environment. The quality of ground and surface waters depends to a large extent on drainage area management, where biogenic substances (i.e. nitrogen, phosphorus and potassium) are transported with surface run-offs to the environment. The article discusses results of studies on the drainage area of Lake Czolnowskie (Zachodniopomorskie Province). Studies covered physical and chemical assessment of soil conditions and water quality; additionally, fish was caught using two independent methods - gillnets and power generator (pursuant to CEN EN 14011 2003 and PN-EN 14011 2006). Results obtained confirm regular run-off of biogenic materials from the surface of farmed drainage area to Lake Czolnowskie. During the period of studies, the reservoir was exposed to i.e. reduction of water oxygen (3.56 mg/dm3) and permanently elevated level of general phosphorus (0.15-0.27 mg/dm3) and ammonium acid (0.16-0.27 mg/dm3), which degraded the quality of life for ichthyofauna inhabiting the lake.

Acceptable Quality

A study was made on the water quality of the rivers in Mongolia over the years 1949–1990 for the three river basins in the country. In most of the 72 monitoring stations, the water quality is governed by geological and hydrological characteristics; bicarbonate and calcium are the most abundant major ions. No significant trends were observed between river discharges and total dissolved solids contents. The sediment yields (expressed in the run-off of total suspended solids, TSS) were always low, viz. between 0.02 and 20 × 103 kg TSS/km2.yr. In general, the rivers in Mongolia showed low pollution levels for organic pollution, phosphorus, nitrogen, etc., and no time trends were observed in this respect. This does not hold, however, for the northern Tuul River, where especially high BOD and ammonium values were found. This can probably be ascribed to the presence of industries and larger cities, as well as agricultural practices. The rivers in Mongolia can generally be classified as “clean” or “of acceptable quality”. In contrast, the Tuul River was shown to be “moderately polluted”, with a deteriorating trend in water quality over recent years.
