Sungai Ranoyapo adalah sungai utama  DAS Ranoyapo yang memiliki luas sekitar 87,154 Ha.  Sungai Ranoyapo melintasi kawasan pertanian, perkebunan, permukiman penduduk, dan industri. Limbah yang berasal dari kawasan tersebut mempengaruhi kualitas air Sungai Ranoyapo. Makrozoobentos dapat digunakan sebagai parameter biologi dalam menentukan kondisi sungai karena hidupnya relatif diam di dasar sungai.   Penelitian ini bertujuan untuk menentukan kualitas air Sungai Ranoyapo berdasarkan indeks keanekaragaman makrozoobentos.   Penelitian dilakukan pada musim hujan yaitu Januari-Maret 2013.  Lokasi penelitian ditentukan dari bagian hulu, tengah dan hilir sungai dengan 3 ulangan di tiap lokasi.   Kualitas air Sungai Ranoyapo ditentukan berdasarkan indeks keanekaragaman makrozoobentos dari Shannon Wiener (H’) menurut kriteria                   Staub et al (1970).  Makrozoobentos di Sungai Ranoyapo terdiri dari 3 Filum, 5 Kelas, 13 Bangsa, 21 Suku, dan 23 Marga. Indeks keanekaragaman makrozoobentos dari Stasiun I (hulu), Stasiun II (tengah) dan Stasiun III (hilir) yaitu 2,43; 2,06; dan 1,77. Kualitas air Sungai Ranoyapo di Stasiun I dan di Stasiun II telah tercemar ringan dengan indeks       H’: 2,0 – 3,0 (H’>2).   Kualitas air Sungai Ranoyapo di Stasiun III telah tercemar sedang dengan indeks     H’ sekitar 1,0 – 2,0 (H’ <2). Kata kunci: Sungai Ranoyapo, kualitas air, pencemaran air, keanekaragaman makrozoobentos MACROZOOBENTHOS AS BIOINDICATOR IN DETERMINING WATER QUALITY OF RANOYAPO RIVER, SOUTH MINAHASA, NORTH SULAWESI ABSTRACT Ranoyapo River is the longest river in the Minahasa Region with its length of  60.5 Km. Ranoyapo River is the main river watershed Ranoyapo which its area of 87.154 ha. Ranoyapo River crosses agricultural, plantation, resident, and industry areas. Waste originated from those areas will affect water quality of Ranoyapo River. Macrozoobenthos can be used as a biological parameter in determining the condition of the river because they relatively slow move on the riverbed. This study aims to determine the water quality of the River Ranoyapo based on biodiversity index of macrozoobenthos. The study was conducted during the rainy season i.e. from January to March 2013. Three locations were chosen from upstream, midstream and downstream river with 3 replications in each location. The quality of Ranoyapo River was determined by the biodiversity index Shannon Wiener (H') of macrozoobenthos using classification of Staub et al (1970. Macrozoobenthos of Ranoyapo River consisted of 3 Phyla, 5 Classes, 13 Orders, 21 Families, and 23 Genus. Biodiversity index (H’) of macrozoobenthos from up (Station I), middle (Station II) and downstream (Station III) respectively were 2.43; 2.06, and 1.77. The quality of Ranoyapo River at up and middle were lightly polluted with index H’: 2.0 to 3.0 (H '> 2.0) and at down was moderately polluted with index H ': 1.0 to 2.0 (H' <2).

This study is only the second to use DNA fingerprinting technology in Maryland to identify fecal coliform sources in order to guide the implementation of water pollution control practices in a watershed with bacterial impairment. By combining the use of digital air photos and GPS with GIS, fieldwork is planned and conducted more efficiently because sample sites can be selected that accurately represent the physical environment of the study area. We can also return to the field and find our sample sites or locate new ones, even in the remotest part of the study area. It is also possible to more accurately map the data directly in the context of its physical environment, greatly increasing the quality of analysis. The integration of DNA fingerprinting techniques with GIS shows great promise for extending our capabilities to identify the controls on water quality and point sources of waterborne health hazards.

A framework for characteristics identification and source apportionment of water pollution in the Jinjiang River of China was proposed in this study for evaluation. A total of 114 water samples which were generated between May 2009 and September 2010 at 13 sites were collected and analysed. First, support vector machine (SVM) and water quality pollutant index (WQPI) were used for water quality comprehensive evaluation and identifying characteristic contaminants. Later, factor analysis with nonnegative constraints (FA-NNC) was employed for source apportionment. Finally, multi-linear regression of the absolute principal component score (APCS/MLR) was applied to further estimate source contributions for each characteristic contaminant. The results indicated that the water quality of the Jinjiang River was mainly at the third level (65.79%) based on national surface water quality permissible standards in China. Ammonia nitrogen, total phosphorus, mercury, iron and manganese were identified as characteristic contaminants. Source apportionment results showed that industrial activities (63.16%), agricultural non-point source (16.50%) and domestic sewage (12.85%) were the main anthropogenic pollution sources which were influencing the water quality of Jinjiang River. This proposed method provided a helpful framework for conducting water pollution management in aquatic environment.

The aim of this study was to evaluate some parameters of water quality of semiarid reservoirs under different uses and occupation of the catchment’s soil. For this, the reservoirs Acauã and Boqueirão, belonging to the Paraíba do Norte river watershed and Middle and Upper course sub catchments, respectively, were studied. For this, water samples were collected in August, September and October 2016. From these samples, total and dissolved phosphorus, nitrate, nitrite, ammonia, chlorophyll, dissolved and suspended solids were analyzed. In addition, images of the Landsat 8 satellite were acquired for the calculation of the Normalized Difference Vegetation Index (NDVI), and for the supervised classification of the use and occupation of the sub catchments. Thus, it was observed that, in general, the Acauã reservoir presented values of phosphorus and nitrogen and solids larger than the Boqueirão reservoir, due to the greater urban area, even though it had a smaller total area of the basin. Both reservoirs presented low vegetation rates and high areas of sparse vegetation and exposed soil, increasing the propensity to soil erosion and the transport of nutrients from the basin to the reservoirs, making water quality worse or impossible.

A study of the water quality of the Adolfo L&oacute;pez Mateos Reservoir (ALMD) was developed through different indicators from a spatial and seasonal perspective. Variables related to the general characteristics of water quality, trophic level and ecological risk were assessed through the water Quality Index (WQINSF-BROWN), Trophic State Index (TSICARLSON) and the Ecological Risk Index (RIHAKANSON). Using data from physical, chemical and biological parameters obtained from four sampling points in the ALMD, the water quality was assessed in each model used. The results indicated that the reservoir presents a water quality classified as &ldquo;medium&rdquo; (WQINSF-BROWN = 70), where significant variations in the concentrations of some parameters are observed. The reservoir showed a general trophic state classified as &ldquo;Mesotrophic&rdquo; (TSIGENERAL-AVERAGE = 43.04). The ecological risk analysis achieved the best classification of the methodology, discarding contamination by heavy metals in surface waters. Through this type of applied methodologies will help as decision making tools in the dam, as well as for application in other dams in the region.
