<p>Surabaya River is very beneficial to Surabaya people as its water becomes the  main source of PDAM (Perusahaan Daerah Air Minum of Regional Water Utility<br />Company). The existing indications on pollution in the flow of Surabaya River due to various activities at its riverbank must not be ignored. Therefore, a study on identifying the distribution of water quality of Surabaya River is required so as to be a reference for formulating control actions to river damage. Identification on water quality distribution was carried out based on the differences of land-use around the left and right sides of river. The research involved the variables of the qualities of river water and waste water thrown into the river, river characteris-tics, and land-use. The results of research  demonstrated that the upstream water quality of Surabaya River was relatively better than the downstream. This statement was proven by the humans’ activities which were more intensively carried out at the downstream area. Numerous land-uses and great number of people living at the riverbank became the phenomena  increasing pressures toward the decreasing quality of river water.</p>

Abstract. River wetlands are heavily impacted by human intervention. The degradation and loss of river wetlands has made the restoration of river ecosystems a top priority. How to rehabilitate rivers and their services has been a research focus. The main goal of it is to restore the river wetland ecosystems with ecological methods. The Gudong River was selected as a study site in Chaoyang city in this study. Based on the analysis of interference factors in the river wetland degradation, a set of restoration techniques were proposed and designed for regional water level control, including submerged dikes, ecological embankments, revegetation and dredging. The restoration engineering has produced good results in water quality, eco-environment, and landscape. Monthly reports of the Daling River show that the water quality of Gudong River was better than Grade III in April 2013 compared with Grade V in May 2012. The economic benefit after restoration construction is 1.71 million RMB per year, about 1.89 times that before. The ratio of economic value, social value and eco-environmental value is 1:4:23.

The river is one of the important water sources and at this time the river water quality has decreased.The type of land use around the river is thought to have a significant contribution to river water quality. This research was conducted to determine of correlation between the type of land use and water quality in Rembangan River, Jember Regency.The study was carried out at four stations that passed through secondary forests, coffee plantations, rice fields and residential housing. The data of biodiversity and density of plants and physical-chemical parameters of river water were noted, and benthic macroinvertebratessamples were collected at each station. Data of biodiversity and density plants were used to determine of environmental services index (ESI) values. Benthic macroinvertebrates samples were identifiedat the family level, and after that the tolerance score and the abundance of each family was determined. The last two data were analyzed to determine of Family Biotic Index (FBI) values.The value of ESI, physico-chemical parameters of river waterand FBI were analyzedto determine the relationship between these variables by using Pearson correlation analysis (α < 0.05).The research result revealed that the type of land use (ESI) was significantly related to the biological quality of river water (FBI) as indicated by the p value > 0.05. The correlation characteristic is negative and very strong (R = 0.886). High ESI values indicate that the diversity and carbon sequestration of plant community around the river are in good condition and vice versa. Low HBI values indicate good river water quality and vice versa. Based on this research, each land use type must provide space for the natural growth of the plant communityto maintain the quality of river water to remain good. Keywords: river, benthic macroinvertebrates, land use, water quality, ESI, HBI.

ABSTRACT: Land use outside its agricultural potential and low vegetation cover in the watershed impair the quality of water used for irrigation and may contribute to the spread of pathogenic coliform bacteria. The objective of this study was to relate the quality of irrigation water with the intensity and type of land use and the rainfall in a vegetable-producing region of São José dos Pinhais, Paraná. Water samples were collected monthly in 2013 from two reservoirs and one preserved source. After collection, the samples were chilled in Styrofoam boxes and transported to the laboratory for analyses of the total and thermotolerant coliforms. Effect of land use was analyzed by probability estimation trees. High land use and weekly above average rainfall increased the probability of thermo tolerant coliforms exceeding the limit allowed under legislation. In regards to thermo tolerant coliforms in the analyzed period, the water from only one reservoir was in accordance with the legislation for the quality of water to irrigate vegetables that are consumed raw. Results of this study are an alert to the local government for the necessity of environmental preservation to maintain the water quality of the county.

AbstrakSungai Klampok mengalir melalui Kecamatan Bergas dan sekelilingnya terdapat beberapa industri sehingga mengakibatkan sungai tersebut tercemar karena menjadi badan penerima air limbah. Akibat penurunan kualitas air Sungai Klampok akan berimbas pada penurunan kualitas air tanah yang digunakan oleh penduduk sekitar sungai tersebut. Penelitian ini bertujuan untuk mengetahui kualitas air tanah yang berada di sekitar Sungai Klampok sebagai akibat adanya pengaruh beban pencemaran oleh air limbah industri berdasarkan Permenkes No. 416/MENKES/PER/IX/1990 tentang persyaratan kualitas air bersih. Lokasi pengambilan sampel air sungai dibagi menjadi 3 stasiun (LK1, LK2 dan LK3) sedangkan untuk sampel airtanah dari rumah-rumah penduduk dilakukan pada 6 titik yaitu 3 titik di daerah utara dari Sungai Klampok (U1,U2, U3) dan 3 titik di daerah selatan dari Sungai Klampok (S1,S2, S3). Pengambilan sampel dilakukan pada musim kemarau. Dari hasil uji kualitas air sungai, pencemaran yang terjadi pada air sungai Klampok masuk dalam kategori tercemar ringan-sedang. Sedangkan hasil uji kualitas air tanah masih berada di bawah baku mutu yang disyaratkan oleh Permenkes No. 416/MENKES/PER/IX/1990, sehingga penurunan kualitas air sungai Klampok tidak mempengaruhi kualitas air tanah di sekitar sungai tersebut. AbstractThe Klampok River flows through the Bergas Subdistrict and there are a number of industries around it, causing the river to become polluted because it becomes the body of the recipient of wastewater. As a result of the decline in the quality of the water in the Klampok River, it will impact on the quality of groundwater used by residents around the river. This study aims to determine the quality of groundwater around the Klampok River as a result of the influence of pollution load by industrial wastewater based on Permenkes No. 416 / MENKES / PER / IX / 1990 concerning requirements for clean water quality. The location of river water sampling is divided into 3 stations (LK1, LK2, and LK3) while for groundwater samples from residential houses is carried out at 6 points, namely 3 points in the northern area of Klampok River (U1, U2, U3) and 3 points in the area south of the Klampok River (S1, S2, S3). Sampling is done in the dry season. From the results of the test of river water quality, pollution that occurs in Klampok river water is categorized as mild-moderate polluted. While the results of groundwater quality testing are still below the quality standards required by Permenkes No. 416 / MENKES / PER / IX / 1990 so that the decline in the water quality of the Klampok river does not affect the quality of groundwater around the river.
