An epilithic benthic algae functions as a primary producer living on rock substrates. The Autotrofic Index (AI) was measured to understand the level of water pollutions by quantifying an autotrofy organism. This research determined water quality of Pitap river based on the autotrofic level of an epilithic benthic algae and to understand the correlation between the autotrofic level and physicochemical parameters. The measurement of water quality based on Ash-Free Dry Mass (AFDM), the amount of chlorophyll-a and physicochemical parameters were taken every month with two repetitions on September and October 2014. Five sampling sites were selected using a purposive sampling method based on the variety of environmental conditions around the Pitap river. The results showed that the water quality in the upstream (Ajung and Langkap villages) were classified non-pollution (dominated by autotrof compounds) until less pollution (dominated by autotrof-heterotof compounds). Other locations in downstream (Tebing Tinggi, Sungsum and Juuh villages) were determined pollution of water quality by dominance of autotrof-heterotrof components to dominance by heterotof components. Spearman correlation explained that autotrofic index on September 2014 was closely correlated with water temperature and water velocity with their value are 0,954 and -0,794 at significantly α=0,01. On October 2014 water temperature was closely correlated with its value 0,681 at significantly α=0,05.

This research aimed at assessing the influence of Municipal Waste on Otamiri River by comparing the levels of the contaminants against the set limit by regulating agencies. Stream samples were collected at five different points along the stream using the conventional WHO (2004) methods. The Physico-chemical of the samples collected were analyzed. The results were compared against the standards of regulating agencies. Spatial variations in Physicochemical parameter variations were observed in the levels of the physicochemical parameters measured across the sampling locations. Maximum levels of pH, water temperature and K+ ions were recorded in sampling Locations (SL) 5 (7.12, 29.00C and 2.73mg/L respectively). Maximum levels of TSS, TDS and Turbidity were recorded in sampling locations 4 and 5 (568.60mg/L, 67mg/L, and 110.24 NTU respectively). Maximum levels of EC, Alkalinity and Acidity were recorded in SL 4, 5 and 1 respectively (154.30mg/L, 37.33mg/L, and 32.44mg/L respectively). Maximum levels of DO, BOD, and Chlorides (5.60 mg/L, 3.53 mg/L, and 120.60 mg/L respectively) were recorded in SL 1 and 2. Maximum levels of Ca+, Mg+ and Na+ ions (64.24 mg/L, 3.60 mg/L, and 5.27 mg/L respectively) were recorded in SL 4 and 5. Maximum levels of Ammonia and Total Hardness were recorded in SL 5 (0.100 and 98.27 respectively). The constant dumping of refuse at the site has increased the concentration of organic and inorganic constituents of the river water, even though some remain within established standards. Water from Otamiri River requires elaborate treatment before it could be suitable for domestic purposes.

Danau Maninjau yang terletak di Provinsi Sumatera Barat telah ditetapkan sebagai salah satu danau prioritas nasional diantara 15 danau lainnya. Kondisi kualitas air Danau Maninjau salah satunya dipengaruhi oleh kondisi kualitas air dari sungai-sungai yang bermuara di danau tersebut. Penelitian ini bertujuan untuk mengetahui kondisi kualitas air sungai inlet Danau Maninjau dengan menggunakan bioindikator makrozoobentos. Penelitian dilakukan pada bulan Juni dan Agustus 2019 di empat sungai inlet Danau Maninjau yang meliputi Sungai Koto Kaciak, Kurambik, Kularian, dan Ranggeh Bayur. Pengambilan sampel makrozoobentos dilakukan di segmen hulu, tengah, dan hilir dengan menggunakan kick net pada substrat berbatu dan berpasir, serta pengeruk Ekman pada substrat berlumpur. Berdasarkan hasil penelitian, ditemukan makrozoobentos di keempat sungai inlet dengan kisaran 5-25 famili dan 4-10 ordo yang tergolong ke dalam delapan kelas meliputi Insekta, Clitellata, Malacostraca, Bivalvia, Gastropoda, Polychaeta, Hirudinea, dan Turbellaria. Hasil analisis korelasi Spearman antara metrik biologi dengan Water Quality Index (WQI)  menunjukkan bahwa metrik SIGNAL, EPT, dan LQI memiliki korelasi yang sangat kuat dengan nilai r > 0,7 (p<0,01). Metrik SIGNAL dengan korelasi tertinggi (r = 0,752) menunjukkan kondisi perairan sungai inlet Danau Maninjau  yang tercemar ringan hingga berat. Metrik SIGNAL, EPT, dan LQI dapat diaplikasikan untuk melengkapi penilaian parameter fisik kimiawi perairan sungai inlet Danau Maninjau. ABSTRACTLake Maninjau which is located in West Sumatra Province has been designated as one of the national priority lakes among 15 other lakes. Water quality conditions of Lake Maninjau is influenced by the condition of the water quality of the streams that flow into the lake. The present study aimed to determine the condition of the water quality of the inlet stream of Lake Maninjau by using macrozoobenthos as bioindicators. This study was conducted in June and August 2019 in four inlet streams of Lake Maninjau including the Koto Kaciak, Kurambik, Kularian, and Ranggeh Bayur streams. A sampling of macrozoobenthos was carried out in the upstream, middle, and downstream using Surber nets on rocky and sandy substrates, and Ekman Grab on muddy substrates. Based on the results of this study, macrozoobenthos were found in the four inlet streams with a range of 5-25 families and 4-10 orders and classified into eight classes including Insects, Clitellata, Malacostraca, Bivalvia, Gastropods, Polychaeta, Hirudinea, and Turbellaria. The results of the Spearman correlation analysis between biological metrics and the Water Quality Index (WQI) show that the SIGNAL, EPT, and LQI metrics have a very strong correlation with r values > 0.7 (p < 0.01). The SIGNAL metric has the highest correlation (r = 0.752) indicates the inlet streams of Lake Maninjau which are lightly to heavily polluted. Metrics of macrozoobenthos communities such as SIGNAL, EPT, and LQI can be applied to complete the assessment of the physicochemical parameters of inlet streams of Lake Maninjau

Tarahara Fish Farm includes 37 large ponds as a fish super zone. Physicochemical parameters viz., air and water temperature, pH, DO, BOD, CO2, Cl-, TA and TH of these ponds were studied for two years (Nov. 2008 to Oct. 2010). The air temperature had positive and significant correlation with water temperature (r=0.893, P<0.01) but inverse and significant correlation with DO (r = - 0.669 P<0.05) and TH (r = - 0.673, P<0.05). Both air and water temperature showed a decreasing trend during the winter months of November to January and again September to October in both years. Similarly, positive and significant correlation showed by pH with DO (r =0.660, P<0.05) and BOD (r =0.846, P<0.05); by free CO2 with DO (r=0.854, P<0.01), chloride (r=0.648, P<0.05) and TA (r=0.616, P<0.05); by DO with TA (r =0.715, P<0.01) and chloride (r =0.625, P<0.05) and by TH with TA (r= 0.592, P<0.05) but inverse and significant correlation showed by pH with water temperature (r =-0.671, P<0.05); by free CO2 with BOD (r=-0.627, P<0.05) and by DO with BOD (r = -0.810, P <0.01). The water quality parameters were within suitable range for the fish growth and breeding with small fluctuations in different months during the first and second years. Physico-chemical parameters significantly (P<0.01; 0.05) differed between different months. However, no mass mortality of fish was recorded from this site. So, the area selected as fish super zone is fruitful to meet the expected production level of fishes and fish seeds in peripheral areas.

Water quality is relevant due to the complexity of the interaction of physicochemical and biological parameters. The Irrigation District 005 (ID005) is one of the most important agricultural region in Chihuahua, México; for that reason, it was proposed to investigate the water quality of the site. Water samples were collected in two periods: Summer (S1) and Fall (S2). The samples were taken from 65 wells in S1, and 54 wells in S2. Physicochemical parameters (PhP) such as Arsenic (As), Temperature, Electrical Conductivity (EC), Oxide Reduction Potential (ORP), Hardness, pH, Total Dissolved Solids (TDS), and Turbidity were analyzed. The data were subjected to statistical principal component analysis (PCA), cluster analysis (CA) and spatial variability tests. In both seasons, the TDS exceeded the Mexican maximum permissible level (MPL) (35% S1, 39% S2). Turbidity exceeded the MPL in S1 (29%) and in S2 (12%). Arsenic was above the MPL for water of agricultural use in 9% (S1) and 13% (S2) of the wells. The PCA results suggested that most variations in water quality in S1 were due to As, pH and Temperature, followed by EC, TDS and Hardness; while in S2 to EC, TDS and Hardness, followed by As and pH.

The Difference

The use of surface waters such as rivers for domestic, agricultural andindustrial purposes have made them vulnerable to pollution leading to impairedwater quality. The water quality of Lahug River in Cebu City was evaluated usingcoliforms as indicators, in relation with physicochemical parameters such as biological oxygen demand (BOD), conductivity, dissolved oxygen (DO), nitrate,pH, phosphate, salinity, temperature, total dissolved solids (TDS) and totalsuspended solids (TSS). Sampling was done once a month from November 2011to April 2012 in three stations covering the upstream, midstream and downstream.The multiple tube fermentation technique was used for the analysis of coliforms.The level of these indicator bacteria increased from the upstream towards thelower reaches of the river especially in the months of February to April; however,the difference in values across time was not significant. This implies that therewas a continuous fecal pollution in the river. There were no statistically significantcorrelations between FCs and TCs with the physicochemical parameters. Anegative relationship was observed among FCs and TCs with pH, TSS, DOand nitrate (p>0.05). These results suggest the presence of sewage and organicpollutants in the river.Keywords: Aquatic Ecology, water quality, coliform, physicochemical parameters,experimental design, Philippines

Water Quality Status

The Mananga River today is a source of potable water to meet the demands of a fast growing Cebu metropolis. The physicochemical parameters of Mananga River were studied to assess its water quality status. Six sample collections were done from February to December 2006 in 3 monitoring stations covering the upstream (S1), midstream (S2) and downstream (S3) of Mananga River. Results showed significant spatial variation (p<0.05) in the studied physicochemical parameters except for alkalinity, total phosphates and nitrate-nitrogen (NO3-N). Significant temporal variation (p<0.05) was also observed for the factors except for stream width, biological oxygen demand (BOD5) and total suspended solids (TSS). Flow velocity showed significant positive correlation with discharge, pH, DO and NO3-N, and negative correlation with water temperature and TSS. Water temperature correlated negatively with DO and pH, and positively with TSS, with the latter showing a positive correlation with BOD5. The results implied that water currents play a major role in the distribution of dissolved substances and the suspension of sediments. Water quality of the studied segments of Mananga River progressively decreased downstream and was more pronounced during the dry periods. Results also indicated that the river was receiving loads of organic matter from natural and anthropogenic sources.   Keywords - ecology, Mananga River, water quality, flow velocity, Cebu City, Philippines
