    Background In August, 2004, following successful field piloting, AdEdge Technologies, Inc. (AdEdge) was selected by the Pueblo of Isleta, located south of Albuquerque, New Mexico, to provide a turnkey project for furnishing an arsenic treatment system, installation, startup, and commissioning to bring the casino water system into compliance with the new maximum contaminant level (MCL) for ...

  • Application of water quality indices to define surface water quality in Tehran

    Tehran is one of the capitals of the world that is not situated around a river, therefore surface water discharges into a network of natural streams and even some artificial canals. Owing to the lack of sewerage system, part of the sewage runs to the network of streams without any control. The aim of this work is to identify a baseline for the water quality, which will then help policy-makers and ...

  • Water recreation and illness severity

    The health endpoint of prior studies of water recreation has been the occurrence of gastrointestinal (GI) illness. This dichotomous measure fails to take into account the range of symptom severity among those with GI illness, and those who develop GI symptoms but who do not satisfy the definition of GI illness. Data from two US cohort studies were used to assess use of ordinal and ...

  • Project profile - Blue Rhino Hamptonville, NC

    Background In 2007, Blue Rhino, located in Hamptonville, NC, contacted AdEdge Technologies, Inc. (AdEdge) to install an iron and manganese treatment system. The amount of iron (5.6 mg/L Fe) and manganese (0.6 mg/L Mn) were well above the maximum contaminant levels of 0.3 mg/L Fe an 0.05 mg/L Mn respectively. The pH of the Blue Rhino site (6.10) was quite below the maximum contaminant ...

  • Best management practices (BMPS) for discharging water from a construction site

  • Catchment process affecting drinking water quality, including the significance of rainfall events, using factor analysis and event mean concentrations

    To ensure the protection of drinking water an understanding of the catchment processes which can affect water quality is important as it enables targeted catchment management actions to be implemented. In this study factor analysis (FA) and comparing event mean concentrations (EMCs) with baseline values were techniques used to asses the relationships between water quality parameters and linking ...

  • Strategies for Managing the Lakes of the Rotorua District, New Zealand

    The Rotorua district in New Zealand contains 12 nationally important lakes. Environment Bay of Plenty (EBOP), which has the responsibility of managing the quality of these lakes, set a routine monitoring program for these lakes and adopted the method of Burns et al. (1999, 2000) to analyse the data and calculate a numeric Trophic Level Index (TLI) value for each. In 1994, the district community ...

  • Changes in the water quantity and quality of the Euphrates river are associated with natural aspects of the landscape

    It has been argued that dam construction and irrigation projects in Turkey and Syria would diminish the flow of the Euphrates River and increase salinity levels. However, previous studies have not systematically defined the baseline changes in the quantity and quality of the river water. In this study, we associate variations in flow quantity and quality of water with natural aspects. We ...
