<p>Physicochemical parameters and nutrient loads of major rivers and streams in Abakaliki, Ebonyi State were studied for a period of seven (7) months from May to November, 2011. Regular and constant monitoring of water bodies is vital to ensure that water quality characteristics are maintained. The results obtained showed; temperature (28.60&ndash;30.00 &deg;C), pH (6.80&ndash;7.93), DO (1.40&ndash;3.53 mg l-1), turbidity (41.33&ndash;97.67 NTU), conductivity (19.00&ndash;613.30 &micro;S cm-1), total acidity (9.17&ndash;17.23 mg l-1), total alkalinity (6.43&ndash;10.97 mg l-1), BOD (1.20&ndash;7.03 mg l-1), COD (16.200&ndash;53.533 mg l-1), Phosphate (0.11&ndash;1.17 mg l-1) and Nitrate (0.12&ndash;1.45 mg l-1) ranges respectively. The turbidity and BOD were well above the prescribed standards. The results suggest that refuse disposal, fertilizer use, and natural phenomena e.g. soil erosion; flooding, etc. may have contributed in various ways to the impairment of the water quality of the studied sites. Although the results do not indicate adverse pollution status of any of the sites, they provided the need for further investigations and monitoring.</p>

The present study was carried out to investigate the desmids biodiversity in traditional freshwater reservoirs of Nagaur district, Western Rajasthan, India. The samples were collected in January 2021 from the freshwater small ponds which harvests rainwater located in and around Nagaur city. These samples were analyzed by following the standard method prescribed by A.P.H.A for assessing the various physicochemical parameters such as pH, TDS, Fluoride, Nitrate, Chloride, total alkalinity, and total hardness to check drinking water quality and for ecological assessment. Furthermore desmids species-level identification and description have been done with the help of standard literatures and monographs. Results of physicochemical parameters indicate the deteriorating drinking water quality of all four sampling sites. In the present study total of 16 species belong to 5 genera i.e. Netrium, Closterium, Cosmerium, Staurastrum, and Eustrum of desmids have been recorded for the first time from the freshwater ponds located in or around the Nagaur city. The higher biodiversity of Closterium and Cosmarium species at Jhada talab confirm its significant relationship with high calcium and nutrient-rich water quality. While low biodiversity of desmids at remaining all village ponds indicates that high pH and oligotrophic quality decreases the desmids biodiversity. Results of this study might be helpful to assess the geographic distribution of desmids flora of Nagaur district and establish water quality of protected freshwater habitats as well as in updating the list of current species of desmids in this sub-region.

A general methodology for the study of water quality in rivers is presented. The paper consists of four parts. In the first part the general characteristics of the area of study, which is the Beli Lom river, and its major pollution sources are presented. The effluent of the Razgrad Wastewater Treatment Plant (RWWTP) has been identified as the most significant pollution point source, due to the inadequate performance of the plant. The second part deals with data collection and processing. Four series of data have been collected, including physical, flow and water quality characteristics. In the third part a 1-d, finite-difference, second-order model is presented. In the fourth part, the model is calibrated, for the determination of its main coefficients, and is successfully verified by predicting the BOD and DO concentrations in the Beli Lom river for all series of data. Finally, the model has been applied to determine the maximum BOD and minimum DO effluent concentrations of the RWWTP, so that a minimum DO concentration is maintained throughout the river.

Malwa region of Punjab state, India has become the center of water borne diseases due to excessive use of pesticides, chemical fertilizers, heavy metals, industrial toxins that cause toxicity in water. The main contamination in ground water is by physico-chemical parameters and heavy metals i.e. pH, total dissolved solids, total alkalinity, total hardness, calcium, chlorides, fluorides, arsenic and lead. The contamination of ground water with heavy metals causes health hazards to humans and animals. Due to lack of adequate facilities and resources for the management and handling of waste, the ground water contamination has been increased. In the present study, assessment of ground water quality was carried out in the villages of Ferozepur district of Punjab state, India. With main emphasis on analyzing the groundwater parameters of Ferozepur district which are responsible for health hazard to humans and animals. Various groundwater samples were collected randomly from the villages of Ferozepur district and analyzed for pH, total dissolved solids, total alkalinity, total hardness, calcium, chlorides, fluorides, heavy metals (arsenic and lead) using standard procedures. The concentrations of calcium, chlorides, fluorides and pH were within the permissible limits, whereas, alkalinity and total hardness were observed beyond permissible limits in most of the water samples. Even among majority of the samples taken, the concentration of arsenic and lead was found within the permissible limits. Results showed that the ground water samples collected from depth ranging from 100 to 360 ft, recorded values within permissible limits for drinking purpose as prescribed by WHO. Further, ANOVA has been applied on analysis results to study the effect of pH on fluoride and chloride, depth on fluoride and chloride and depth on arsenic and lead. Also, to adjudge the overall quality of water in Ferozepur district, the water quality index (WQI) has been calculated on the basis of large number of physico-chemical characteristics of water. The water quality index of ground water in Ferozepur district has been calculated to be 107. The value is close to 100 so the quality of ground water in Ferozepur district can be categorized under 'Good Quality' water.

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

Safe source of drinking water is always considered as an essential factor in water supply for cities and urban areas. As a part of this issue, drinking water quality is monitored via a useful scheme: developing drinking water quality index DWQI. DWQI is preferably used as it summarizes the whole physicochemical and bacteriological properties of a drinking water sample into a single and simple term. In this study, an evaluation was made for three drinking water treatment plants DWTPs named: Efraz 1, Efraz 2 and Efraz 3 that supply drinking water to Erbil City. The assessment was made by testing thirteen physicochemical and two bacteriological parameters during a long period of (2003 – 2017). It has been found that turbidity, electrical conductivity EC, total alkalinity, total hardness, total coliform and fecal coliform have more influence on drinking water quality. DWQI results showed that the quality of drinking water supplied by the three DWTPs in Erbil City fallen within good level. Except various occasional periods where the quality was varying from good to fair. The quality of the drinking water supply never reached the level of marginal or poor over the time investigated. The applied hierarchical clustering analysis HCA classifies the drinking water dataset into three major clusters, reflecting diverse sources of the physicochemical and bacteriological parameter: natural, agriculture and urban discharges.
