The analysis of river pollution and assessment of spatial and temporal variation in hydrochemistry are essential to river water pollution control in the context of rapid economic growth and growing pollution threats in China. In this study, we focused on hydrochemical characteristics of the Luanhe River Basin (China) and evaluation of 12 hydrochemical variables obtained from 32 monitoring stations during 2001–2010. In each study year, the streams were monitored in the three hydrological periods (April, August, and October) to observe differences in the impacts of agricultural activity and rainfall pattern. Multivariate statistical methods were applied to the data set, and the river water hydrochemical characteristics were assessed using the water quality identification index (WQIIM). The results showed that parameters had variable contribution to water quality status in different months except for ammonia nitrogen (NH4-N) and total nitrogen (TN), which were the most important parameters in contributing to water quality variations for all three periods. Results of WQIIM revealed that 18 sites were classified as 'meeting standard' while the other 14 sites were classified as 'not meeting standard', with most of the seriously polluted sites located in urban area, mainly due to discharge of wastewater from domestic and industrial sources. Sites with low pollution level were located primarily in smaller tributaries, whereas sites of medium and high pollution levels were in the main river channel and the larger tributaries. Our findings provide valuable information and guidance for water pollution control and water resource management in the Luanhe River Basin.

Water Pollution Control

 Sirau River is one of the rivers in the Barito Timur Regency which flows through the Dusun Timur District. Sirau River water is used as raw material for regional water companies (PDAM) and is used by communities around the river to meet the needs of other daily life such as MCK and other uses and is also used as a landfill, domestic wastewater and waste water mining and plantation activities both directly and indirectly. This study aims to analyze the status of pollution of the Sirau river through the approach of the pollution index value, assess the quality of the Sirau River water and identify the source of pollutants entering the Sirau River. The results showed that in general the water quality of the Sirau River for pH, COD, BOD, Fe, and Mn parameters exceeds the water quality standard namely Government Regulation No. 82 of 2001 class II concerning Water Quality Management and Water Pollution Control, the main source of pollutants comes from residential domestic waste, coal mining activities and dry leaves that fall into river streams. Sirau river water quality from upstream to downstream based on river water quality analysis using the pollution index method shows that water quality has decreased where the river conditions are generally mildly polluted. The quality of lightly polluted Sirau river water cannot be utilized in accordance with the designation of class II water based on Government Regulation No. 82 of 2001 concerning Management of Water Quality and Water Pollution Control.

Quality Status

Sebagian besar limbah cair hasil dari kegiatan manusia dibuang ke saluran. Sekitar 60% pencemaran KaliSurabaya berasal dari limbah domestik (Fatnasari dan Hermana, 2010). Padahal air Kali Surabaya memasoksekitar 96% kebutuhan air baku Perusahaan Daerah Air Minum (PDAM) Kota Surabaya (Herera dkk, 2013).Penelitian ini bertujuan untuk mengidentifikasi tingkat pencemaran dan menentukan prioritas strategipengendalian pencemaran air Kali Surabaya menggunakan AHP (Analitycal Hierarchy Processes).Pengumpulan data sekunder berupa data kualitas air Kali Surabaya yang terdiri dari temperatur, TSS, pH,BOD, COD, DO, nitrat, amonia, kromium, tembaga, nitrit, minyak, deterjen, fenol, total coli, dan faecal coliyang dibandingkan dengan baku mutu air kelas 2 berdasarkan Peraturan Pemerintah nomor 82 tahun 2001.Kemudian dilakukan penentuan status mutu air Kali Surabaya menggunakan metode indeks pencemaranberdasarkan Keputusan Menteri Lingkungan Hidup Nomor 115 tahun 2003. Analisis Strategi pengendalianpencemaran air Kali Surabaya didapat setelah dilakukan pembagian kuesioner kepada Badan LingkunganHidup Provinsi Jawa Timur, Dinas Pekerjaan Umum Pengairan, Perum Jasa Tirta, Dinas Perindustrian danPerdagangan, PDAM dan Tokoh Masyarakat. Hasil penelitian menunjukkan bahwa parameter pencemar airKali Surabaya adalah TSS, BOD, DO, nitrit, minyak, dan fenol. Selain itu, status mutu air Kali Surabayatermasuk tercemar ringan. Hasil running prgram AHP diketahui bahwa strategi pengendalian pencemaran airKali Surabaya lebih menitik beratkan pada ketegasan dalam menaati peraturan perundangan yang berlaku. The Surabaya River’s main problem currently was the wastewater resulted from human activities mostly being discharged into the river. About 60% of Surabaya River pollution originated from domestic wastewater (Fatnasari dan Hermana, 2010). Infact, about 96% of water Perusahaan Daerah Air Minum (PDAM) Surabaya take from this river (Herera dkk, 2013). This study aims for identification of pollution level and determination of strategy priority of water pollution control in Surabaya River using Analytical Hierarchy Processes (AHP). The study was begun from secondary data collection of water quality parameter of: temperature, TSS, pH, BOD, COD, DO, nitrate, nitrite, ammonia, chromium, copper, oil, detergent, phenol, total coli and faecal coli. The data would be compared with stream standard. Then quality status of Surabaya River water was determined by using pollution index method according to Ministry of Environment Decree N0. 115/2003. The analysis of strategy to control Surabaya River water was done by questionnaire and direct interview methods to Badan Lingkungan Hidup (BLH) of East Java Province, Dinas Pekerjaan Umum Pengairan, Perum Jasa Tirta I, Dinas Perindustrian dan Perdagangan, PDAM and several affectional peoples in society. The result of study shows that the polluting parameters of water in Surabaya River were TSS, BOD, DO, nitrite, oil and phenol. The water quality status of Surabaya River is categorized as low polluted. From the result of AHP the strategy of water pollution control in Surabaya River should be focused on social aspect which more focused firmness in keeping the existing regulations

Recreation Benefits

Water pollution control policies generally direct sources (i.e., industry, agriculture) to reduce loadings of certain pollutants. Thus, evaluating the relative net recreation benefits of policies to improve water quality requires establishing a linkage between the sources, the resultant water quality degradation at the affected water bodies, and, ultimately, the effect on recreation behavior. This linkage is rarely present in the empirical literature which is, thus, deficient for water pollution control policy assessment purposes. In this paper, we estimate the relative recreational swimming benefits that may result from controlling point and nonpoint sources of pollution, respectively, in New Hampshire's lakes. We use a repeated discrete choice framework to model swimming behavior as a function of each lake's level of eutrophication, bacteria, and oil and grease. For each pollutant, at each affected lake, we identify which source is responsible for the pollution, and we conduct scenarios controlling each pollution source independently, and then, taken together. Seasonal benefit estimates are presented for each scenario. Coupled with information on the most cost effective means of generating the scenarios, these estimates provide a useful starting point for a quantitative assessment of the net recreation benefits of policies to improve the quality of New Hampshire lakes.
