Water Quality Standards

Ecological status of Malaysia is not as bad as many other developing nations in the world. However, despite the enforcement of the Environmental Quality Act (EQA) in 1974, the water quality of Malaysian inland water (especially rivers) is following deteriorating trend. The rivers are mainly polluted due to the point and non-point pollution sources. Point sources are monitored and controlled by the Department of Environment (DOE), whereas a significant amount of pollutants is contributed by untreated sullage and storm runoff. Nevertheless, it is not too late to take some bold steps for the effective control of non-point source pollution and untreated sullage discharge, which play significant roles on the status of the rivers. This paper reviews the existing procedures and guidelines related to protection of the river water quality in Malaysia.  There is a good possibility that the sewage and effluent discharge limits in the Environmental Quality Act (EQA) may pose hindrance against achieving good quality water in the rivers as required by the National Water Quality Standards (NWQS). For instance, Ammoniacal Nitrogen (NH3-N) is identified as one of the main pollutants to render many of the rivers polluted but it was not considered in the EQA as a monitoring parameter until the new regulations published in 2009.  Surprisingly, the new regulation for sewage and industrial effluent limits set allowable NH3-N concentration quite high (5 mg/L), which may result in low Water Quality Index (WQI) values for the river water. The water environment is a dynamic system. Periodical review of the monitoring requirements, detecting emerging pollutants in sewage, effluent and runoff, and proper revision of water quality standards are necessary for the management of sustainable water resources in the country. ABSTRAK: Satus ekologi Malaysia tidak seburuk kebanyakan negara membangun lain di dunia. Walaupun Akta Kualiti Alam Sekitar (EQA) dikuatkuasakan pada tahun 1974, kualiti air di pedalaman Malaysia (terutama sungai) semakin merosot. Kebanyakan sungai tercemar akibat pencemaran di punca sumber air dan pencemaran di bukan punca sumber air. Punca sumber air dipantau dan dikawal oleh Jabatan Alam Sekitar (JAS), tetapi sejumlah besar pencemaran adalah sisa yang tidak dirawat dan air larian ribut. Walau bagaimanapun, ia tidak terlambat untuk mengambil beberapa langkah berani untuk mengawal pencemaran di punca sumber air dan sisa tidak dirawat kerana langkah ini memainkan peranan penting bagi kebersihan sungai. Kertas kerja ini mengkaji prosedur dan garis panduan sedia ada berkaitan perlindungan kualiti air sungai di Malaysia. Ada kemungkinan bahawa had kumbahan dan pelepasan efluen dalam Akta Kualiti Alam Sekitar (EQA) boleh menimbulkan halangan terhadap mencapai kualiti air yang baik di dalam sungai seperti yang dikehendaki oleh Piawaian Kualiti Kebangsaan Air (NWQS). Sebagai contoh, Ammoniakal Nitrogen (NH3-N) dikenal pasti sebagai salah satu bahan pencemar utama yang menyebabkan banyak sungai tercemar tetapi ia tidak dianggap sebagai parameter pemantauan dalam EQA hingga peraturan baru diterbitkan pada tahun 2009. Yang menghairankan, peraturan baru menetapkan had efluen perindustrian dan kumbahan dibenarkan pada kepekatan NH3-N yang agak tinggi (5 mg / l), dan ini mungkin menyebabkan nilai Indeks Kualiti Air (WQI) sungai rendah. Persekitaran air adalah sistem dinamik. Menjalankan semakan berkala mengenai syarat pemantauan, mengesan bahan pencemaran di dalam kumbahan, efluen dan aliran, dan semakan piawaian kualiti air yang wajar adalah perlu bagi pengurusan sumber air lestari di negara ini.

Quality Status

It is very important to know the status of river water quality, in order to determine the direction of resource management which is decreasing in quality according to its allocation. Analysis of the status of the water quality of the Ayung River in Bali Province using secondary data in the form of data on illness results from 2014 to 2018. The number of parameters applied to the fire is 16 parameters with class II water quality standards referring to attachment XII of Bali Governor Regulation No. 16 of 2016 concerning Environmental Quality Standards and Environmental Damage Standard Criteria. The analysis used the Storetic Method (Decree of the Minister of Environment Number 115 of 2003). The results of the analysis show that the status of Ayung River water is at very good, good and moderate levels. The status of the Ayung River's air quality tends to decline from year to year and from upstream to downstream. Status determining parameters are: BOD5, phosphate, phenol, detergent and sulfide. Key words: water quality status; ayung river; storet.

Water pollution affects water security, reducing water supply to economic water uses and threatening environmental preservation and human health. Controlling water pollution depends on efforts on two main sectors. One is water management, which provides regulatory instruments, including water quality standards, water abstraction and water discharge permits, as well as economic instruments, like water and wastewater charges. Another is sanitation, which is responsible for expansion of water and wastewater infrastructure and faces challenges in financing extensive infrastructure. While water management defines broader (watershed scale) strategies to address water quality, other decisions regarding infrastructure investment are made by the sanitation sector at the municipality scale, with limited perception of broader watershed context on water availability and pollution. When water management and sanitation decisions are not coordinated there are missed opportunities to (a) meet water quality standards at given river reaches due to lacking investment upstream and (b) find least cost investment solutions across municipalities, at the watershed scale. In this paper, we present methods and solutions to coordinate wastewater infrastructure expansion planning with water management instruments in the long-term planning to maximize economic returns and improve water quality. Our methods identify the regions where investments could be prioritized, coordinated with the distribution of water permits and definition of water quality targets. Results show that restricting water permits on some watershed regions results in a small water availability trade-off for economic uses but a significant reduction in costs to sanitation investments, while also meeting the water quality targets. We conclude that while there are several ways to reach predefined water quality targets, each way requires well-coordinated decisions from the water management perspective (where and when to allocate water permits) and the sanitation sector (where and when to concentrate investments in wastewater treatment). Thus, as important as the decisions to improve water management instruments and to increase investments in sanitation is their coordination towards a common watershed goal

ABSTRAKSungai Kupang adalah salah satu sungai yang mengalir di Kota Pekalongan yang menerima limbah, baik dari industri, pertanian maupun domestik, Perkembangan industri dan pemukiman di sepanjang aliran sungai Kupang telah mempengaruhi kualitas air sungai. Penurunan kualitas air ditandai dengan perubahan warna air dan bau padahal sebahagian masyarakat di pinggiran sungai masih memanfaatkan air Sungai Kupang untuk kebutuhan sehari-hari. Penelitian ini bertujuan untuk menganalisis kualitas air sungai Kupang berdasarkan baku mutu kualitas air sungai menurut PP Nomor 82 Tahun 2001, menghitung beban pencemar Sungai Kupang dan menentukan Status Mutu Air serta merekomendasi upaya pengelolaan kualitas air Sungai Kupang Pekalongan. Pengukuran kualitas air dilakukan pada 6 titik pengambilan sampel. Parameter yang diukur dan diamati adalah parameter Temperatur, TSS, pH, DO, BOD, COD, Kromium dan Phosphat. Untuk analisis Status mutu air Sungai Kupang dengan menggunakan metode indeks pencemaran dan daya tampung beban pencemaran dengan menggunakan metode Qual2Kw. Hasil penelitian pada kualitas air Sungai Kupang menunjukkan parameter  COD di beberapa titik telah melebihi baku mutu. Sedangkan untuk parameter BOD di semua titik telah melebihi baku mutu yang dipersyaratkan. Nilai konsentrasi BOD terendah adalah sebesar 5,75 mg/l, sedangkan nilai BOD tertinggi sebesar 27 mg/l. Kandungan BOD meningkat diduga karena sepanjang aliran sungai yang di mulai dari hulu hingga hilir banyak menerima limbah buangan, sementara berdasarkan status mutu air menunjukkan penurunan kualitas air dari hulu sampai ke hilir sungai, dimana pada bagian hilir telah tercemar ringan. Dan untuk hasil perhitungan beban pencemaran Sungai Kupang dari hulu ke hilir mengalami peningkatan, untuk beban pencemaran konsentrasi TSS adalah sebesar 20.670,334 kg/hari, sedangkan konsentrasi COD adalah sebesar 16.517,777 kg/hari, dan konsentrasi BOD yaitu sebesar 6.618,643 kg/hari.Kata kunci: Water Quality, Pollution Load, Kupang River ABSTRACTSungai Kupang is one of the rivers that flow in Pekalongan city that receives the waste, both from industrial, agricultural and domestic, industrial and residential development along the river Kupang have affected the quality of river water. Water quality degradation characterized by changes in water color and odor when sebahagian riverside communities still use river water Kupang for everyday needs. This study aimed to analyze the water quality of the river Kupang based on river water quality standards in accordance with Regulation No. 82 of 2001, calculating the pollutant load Sungai Kupang and determine Air Quality Status and recommend management measures Pekalongan Kupang River water quality. Water quality measurements performed at 6 sampling points. Parameters measured and observed are the parameters of temperature, TSS, pH, DO, BOD, COD, chromium and Phosphate. For the analysis of the water quality of Sungai Kupang status using the pollution index and pollution load capacity using Qual2Kw.The results of research on water quality of Sungai Kupang shows COD parameter at some point has exceeded the standard quality. As for the parameters BOD at all points have exceeded the quality standards required. BOD value is the lowest concentration of 5.75 mg / l, while the highest value of BOD of 27 mg / l. The content of BOD increased presumably because the watershed is in from upstream to downstream received many waste dumps, while based on the status of water quality showed a decrease in water quality from upstream to downstream, which in part has been lightly polluted downstream. And also for the calculation of pollution loads Kupang River from upstream to downstream has increased, to the pollution load of TSS concentration amounted 20670.334 kg / day, while the COD concentration is equal to 16517.777 kg / day, and the BOD concentration is equal to 6618.643 kg /day.Keywords:  Water Quality, Pollution Load, Kupang RiverCara sitasi: Pohan, D.
