It nas been proved that planting various aquatic vascular plants with proper arrangements of time and space in tne eutropnic water of tne Cao Yang Round Creek nas formed an effective and stable ecological system for purifying water. Within two years, the water quality of the Round Creek has been improved significantly. The density of algae (content of chlorophyll a) has dropped by 95%, the total suspended solids is decreased by more tnan 90%, and COD is also reduced by 50%. The transparency of the water has increased from 15cm Before treatment to 53cm after treatment. Some parts of tne Creek are clear enough to see the bottom, to count tne fish. At the same time, beautification and planting of plants on the water surface has been carried our, together with the purification of the water. In this way, tne sightseeing value of water body is also increased. The paper intends to probe an efficient way of harnessing the eutropnic water By practicing witn purification, Deautification and plant planting all at one time.

Correlations between water quality parameters and seagrass depth penetration were developed for use as a biological indicator of integrated light availability and long-term trends in water quality. A year-long water quality monitoring programme in Moreton Bay was coupled with a series of seagrass depth transects. A strong gradient between the western (landward) and eastern (seaward) portions of Moreton Bay was observed in both water quality and seagrass depth range. Higher concentrations of chlorophyll a, total suspended solids, dissolved and total nutrients, and light attenuation coefficients in the water column and correspondingly shallower depth limits of the seagrass Zostera capricorni were observed in the western portions of the bay. Relatively high correlation coefficient values (r2 > 0.8) were observed between light attenuation coefficient, total suspended solids, chlorophyll a, total Kjeldahl nitrogen and Zostera capricorni depth range. Low correlation coefficient values (r2 < 0.8) between seagrass depth range and dissolved inorganic nutrients were observed. Seagrasses had disappeared over a five-year period near the mouth of the Logan River, a turbid river with increased land use in its watershed. At a site 9 km from the river mouth, a significant decrease in seagrass depth range corresponded to higher light attenuation, chlorophyll a, total suspended solids and total nitrogen content relative to a site 21 km from the river mouth. Seagrass depth penetration thus appears to be a sensitive bio-indicator of some water quality parameters, with application for water quality management.

Pinheiros River (Brazil) plays a pivotal role in supplying water to Billings Reservoir, which presents multiple uses (human drinking, energy generation, irrigation, navigation, fishing and leisure). An intense monitoring program was performed during the years 2007 and 2008 to find out whether on site flotation is a feasible solution or not for improving the water quality of this urban river, attenuating the pollutants load caused by the water pumping to the reservoir (approximately 10 m3 s−1). The monitoring of 18 variables (13,429 laboratorial analysis during the period of 490 days), suggested that despite the convenience of the on site approach for water treatment, especially for rivers located in fully urbanized areas, the flotation system is not enough itself to recover Pinheiros River water quality, given the several constraints that apply. Total phosphorus removal was high in percentage terms (about 90%), although the remaining concentrations were not so low (mean of 0.05 mg L−1). The removal efficiency of some variables was insufficient, leading to high final mean concentrations of metals [e.g. aluminium (0.29 mg L−1), chromium (0.02 mg L−1) and iron (1.1 mg L−1)] as well as nitrogen-ammonia (25.8 mg L−1) and total suspended solids (18 mg L−1) in the treated water.

Data Set

The present study evaluated the spatial variations of surface water quality in a tropical river using multivariate statistical techniques, including cluster analysis (CA) and principal component analysis (PCA). Twenty physicochemical parameters were measured at 30 stations along the Batang Baram and its tributaries. The water quality of the Batang Baram was categorized as “slightly polluted” where the chemical oxygen demand and total suspended solids were the most deteriorated parameters. The CA grouped the 30 stations into four clusters which shared similar characteristics within the same cluster, representing the upstream, middle, and downstream regions of the main river and the tributaries from the middle to downstream regions of the river. The PCA has determined a reduced number of six principal components that explained 83.6% of the data set variance. The first PC indicated that the total suspended solids, turbidity, and hydrogen sulphide were the dominant polluting factors which is attributed to the logging activities, followed by the five-day biochemical oxygen demand, total phosphorus, organic nitrogen, and nitrate-nitrogen in the second PC which are related to the discharges from domestic wastewater. The components also imply that logging activities are the major anthropogenic activities responsible for water quality variations in the Batang Baram when compared to the domestic wastewater discharge.

Water is essential part of ecosystem, so its quality must be ascertained for use especially in Ekole creek of Nigeria where dredging activities is heavy, hence this study examined the dredging effect on the downstream water quality of Ekole creek. Water samples were collected from four points which are; Upstream, Dredge I, Dredge II, and Downstream points. The parameters of the water quality determined showed that Turbidity and Total Suspended Solids (TSS) were higher at the Downstream point with values of 31 NTU and 1664 mg/l respectively; pH was also slightly acidic (6.61); but low in Total Dissolve Solid (TDS), Electrical Conductivity,  Nitrate (NO3) and Dissolved Oxygen (DO), as compare to the Upstream. The values of the  heavy metals like Pb (3.845 mg/l), Cr (0.612 mg/l) Ni (0.104 mg/l) and Cu (0.128 mg/l),  at Downstream point, were above Pb (3.0605 mg/l), Cr (0.0 mg/l), Ni (0.017 mg/l) and Cu (0.102 mg/l) of  the Upstream point,before the Dredging points I and II, that have  correlative matrix of(Pb>Fe>Mn>Zn>Cu>Ni>Cr) and  Pb>Fe>Cr>Mn>Zn>Cu>Ni Downstream point. Is discovered the Downstream water is slightly acidic, high in Turbidity and TSS, but low in TDS, EC, NO3 and DO, as against the WHO drinking-water quality, due the effect of dredging on the water quality of the Ekole Creek. It is inferred that the dredging activities have negative effects on the water quality, which can be hazardous to the health of downstream user, and distort the ecosystem; therefore the commercial dredging activities should be checked in Ekole creek.

Aim: To evaluate water quality of the river Birim after a two-year ban as a result of illegal mining activities in the catchment areas of the river. Methodology: Samples were taken during wet and dry seasons in acid-washed plastic containers. Two water quality indices were adapted for the river under study and used in the evaluation. These were Water Quality Index (WQI) and Heavy Metal Pollution Index (HPI). Twelve physicochemical parameters, such as pH, turbidity, conductivity, total suspended solids, total dissolved solids, total hardness, alkalinity, sulphate, phosphate, nitrate, Fluoride, and chloride which were life-threatening and generally acceptable in water quality were used to evaluate the water quality index. The computed WQI was 439.168, which fell within the unfit for drinking category with turbidity and total suspended solids positively influencing the index.  Iron, (Fe), As, Mn, and Hg were used to evaluate HPI, with an index value of 39.49, which was excellent considering a critical value of 100 set, below which the water is fit for good drinking water. Conclusion: Except for heavy metal pollution, the river Birim is unfit for drinking without chemical treatment and that, the two-year ban on artisanal small-scale mining was not enough for the river to recover fully from previous pollution episodes and hence did not have any impact on water quality of the river Birim.

Water quality deterioration has become an essential concern worldwide due to climatic ‎changes and increased pollution. As a result, the available drinking water supply resources‏ ‏will receive its ration of this deterioration. This study was conducted to monitor the water ‎quality of the Tigris River in eight different locations in Baghdad during the period ‎between 2005 and 2013. Water samples were collected and analyzed for fourteen ‎selected physicochemical parameters including alkalinity, total hardness (TH), turbidity, ‎total suspended solids (TSS), temperature, pH, nitrate, nitrite, phosphate, electrical ‎conductivity (EC), chloride, calcium, magnesium, and sulfate. To show the spatial and ‎temporal variations of the selected parameters along the study area easily and objectively, ‎Geographical Information System maps (GIS maps) were used. Results showed that the ‎obtained values in winter of alkalinity, turbidity, electrical conductivity, and the ‎concentration of calcium, magnesium, sulfate, nitrite, phosphate, chloride, and total ‎suspended solids were higher as compared with the corresponding values in summer. On ‎the other hand, temperature, total hardness, pH, and nitrate values were higher in summer ‎as compared with the corresponding values in winter. The water quality of Tigris River ‎throughout the study period was within the permissible limits of the Iraqi standards for ‎drinking water.‎

Abstract Fish farming and especially rearing and breeding of rainbow trout and carp is one of potential sources of surface water pollution. The study was aimed at assessing the effect of a rainbow trout farm on water quality in the Gowienica River in winter. Temperature, pH, electrolytic conductivity, total suspended solids, dissolved oxygen, BOD5, CODCr, alkalinity, water hardness, calcium, magnesium, ammonium-nitrogen, nitrate-nitrogen (III and V) and total phosphorus were determined according to Polish Norms and APHA [1995] in water samples collected in winter up- and downstream the study object. The increment of pollutant concentrations in rainbow trout farm effluents was referred to the requirements in Rozporządzenie MŚ [2006]. Performed studies and literature review show that effluents from the assessed fish farm did not worsen water quality of the river. Increased concentrations of total suspended solids and CODCr in effluents were noted only in March. According to data from the report on environmental status in zachodniopomorskie province in the years 2008-2011, poor water quality of the Gowienica River is recorded already upstream the rainbow trout farm. Pollution of this stretch of the river may originate from uncontrolled waste water management and from nutrient runoff from fields.
