  • Water Quality Assessment and Onshore Development in Tropical Waters

    Standards for bacteriological recreational water quality in Puerto Rico are those proposed by US EPA. The standard for primary contact recreational use has both single-sample limits and running- average threshold limits based on historical data developed for the specific site. La Parguera is the site of a Special Marine Reserve and counts among its unusual habitats a phosphorescent bay, important ...

  • An integrated approach for urban water quality assessment

    This paper introduces an integrated approach for the assessment of receiving water quality and the relative contribution of the urban drainage system to perceived receiving water quality problems. The approach combines mass balances with relatively simple receiving water impact models. The research project has learned that the urban drainage system is only one of the determining factors with ...

  • Simulation adequacy assessment of water quality of Rosetta Branch

    Quality status of fresh waterways in Egypt, especially those that receive agricultural drainage water such as Rosetta Branch (RB), is critical for most of its water uses. However, the country depends on this marginal quality water to fill the gap between demand and supply. Therefore, the need for effective/economic water management tools turn into an obligation. Mathematical models can be ...

  • Water quality assessment of a polluted urban river

    Urban rivers in Latin America are heavily impacted by human activities that affect their functions and services. This paper shows the results of a water quality assessment for the Reconquista River, the second most polluted urban river in Argentina. They allowed the identification of the main processes of transport of pollutants and the prioritisation of different areas of the basin for ...

  • Xylem helps Italian spa go with the flow

    A case study on the termal Hotel Mamma Margherita, Abano Terme (Padova) For many people, a relaxing break in a secluded Italian spa is the ideal way to recharge. However, what many may not be aware of is the importance of a solid and reliable pumping system to keep activity above the surface running seamlessly. Hotel Mamma Margherita, situated in Padua, north-east Italy, ...

  • Assessing water quality in Europe using stratification techniques

    This report aims to provide information in relation to the trends of major nutrients in rivers. It focuses both on the trends considered as indicators of water quality status and on the possible differences in trends in relation to main driving forces (agriculture, urbanisation). Referring to the driving forces — pressures — state — impact — response (DPSIR)assessment framework of the EEA, the ...

  • Selection of monitoring locations for storm water quality assessment

    Storm water runoff is a major contributor to the pollution of receiving waters. Storm water characteristics may vary significantly between locations and events. Hence, for each given location, this necessitates a well-designed monitoring campaign prior to selection of an appropriate storm water management strategy. The challenge for the design of a monitoring campaign with a given budget is to ...

  • Assessment of River Water Quality in Northwestern Greece

    The effect of land use patterns on river water quality was studied in three different river basins located in Epirus, Northwestern Greece. Studies were conducted from October 2000 to {September} 2001. During this period, the parameters chemical oxygen demand (COD), biological oxygen demand (BOD), NO2–, NO3–, NH4+ and PO43– were measured, employing standard methods of analysis. The results were ...

  • Turbidity tubes for drinking water quality assessments

    Turbidity tubes have been considered to be the field method of choice for drinking water quality monitoring in resource-limited contexts because of their relative simplicity and low cost in comparison with conventional (nephelometric) turbidimeters. These tubes utilise the principle of visual extinction of a submerged target for turbidity determination and were therefore thought to be subject to ...

  • Ecological Quality Ratios for Ecological Quality Assessment in Inland and Marine Waters

    The REBECCA project focuses on establishing quantitative relationships between physicochemical and hydromorphological pressures and biological indicators. One of the major applications of such relationships is to support the establishment of WFD compliant assessment and classification methods. All EU Member States are required to establish such methods for the different biological quality ...


  • Assessment of groundwater quality in sunamganj of Bangladesh

    Huge quantities of groundwater, particularly from the shallow aquifers, are used for irrigation in Bangladesh and in the absence of adequate surface water in the dry season, irrigation becomes heavily dependent on groundwater. The water quality management is essential for long-term irrigation system as it persuades the soil properties. In irrigation water evaluation, emphasis is given on chemical ...

  • Development of a water quality assessment model: a water quality assessment model based on watershed characteristics by non-linear regression

    Here, a water quality assessment model (WQAM) is developed by non-linear regression as an alternative to physical watershed modeling in South Korea. Three cases and 10 scenarios are applied and reviewed to determine the most appropriate WQAM. The three cases are: (1) the area size allocation of sub-watersheds, (2) the watershed imperviousness ratio, and (3) the combination of the area size and ...

  • Impact assessment of waste disposal on water quality of a freshwater reservoir of India

    Physico–chemical parameters and heavy metals were analysed in water samples, collected during rainy, winter and summer season of 2006–2007 to evaluate the impact of wastes on Halali reservoir. In surface water temperature, pH, TDS, EC, free CO2, DO, alkalinity, hardness and chloride were from 18.3–35.5°C, 7.4–8.9, 103–509 mg L−1, 162–800 ...

  • Assessment of water resources management and quality of El Salam Canal, Egypt

    The Government of Egypt implemented El Salam Canal project to reuse drainage water, to create new communities along the Canal and to re–chart Egypt's population map. The objectives of the present study are to evaluate the quantity of the drainage water which feed El–Salam Canal, and the quality of water discharge through the course of El Salam Canal. This paper assesses water quality of El Salam ...

  • Assessment of the quality, effectiveness, and acceptability of ceramic water filters in Tanzania

    Globally, approximately two billion people drink contaminated water. Use of household water treatment (HWT) methods, such as locally manufactured ceramic filters, reduces the diarrheal disease burden associated with unclean water. We evaluated the quality, effectiveness, and acceptability of ceramic filters in two communities in Arusha, Tanzania, by conducting: 1) baseline household surveys ...

  • Methods for microbiological quality assessment in drinking water: a comparative study

    The present study aimed to compare several methods for quantifying and discriminating between the different physiological states of a bacterial population present in drinking water. Flow cytometry (FCM), solid-phase cytometry (SPC), epifluorescence microscopy (MSP) and culture method performances were assessed by comparing the results obtained for different water samples. These samples, ...
