  • What’s Hiding in the Water?

    As we grow in understanding the significance different organisms have in the ecology of an environment, it helps tremendously if we knowwhich organismsinhabit that environment – whether they’re supposed to be there or not.  One method that is gaining widespread use, and relies on a simple filtration method, is the analysis of environmental DNA (eDNA) from local waterways. ...

  • Seasonal patterns of drinking water consumption pattern in Mysore City, Karnataka, South India

    The aim of this study is to determine the general drinking water consumption pattern in Mysore city, Karnataka, South India with special reference to cold water (without boiling), and to construct a data base for water consumption habits of Mysore people. In developing countries microbial risk assessment studies, water intake values are often adopted from developed countries. However, these ...

  • How a new source of water is helping reduce conflict in the Middle East

    Scientists and others look to desalination as a way to unite longtime enemies in a common cause. Ten miles south of Tel Aviv, I stand on a catwalk over two concrete reservoirs the size of football fields and watch water pour into them from a massive pipe emerging from the sand. The pipe is so large I could walk through it standing upright, were it not full of Mediterranean seawater pumped ...

  • iSTREEM®: An approach for broad‐scale in‐stream exposure assessment of “down‐the‐drain” chemicals

    The iSTREEM® model (“in‐stream exposure model”), a web‐based model made freely available to the public by the American Cleaning Institute, provides a means to estimate concentrations of “down‐the‐drain” chemicals in effluent, receiving waters, and drinking water intakes across national and regional scales under mean annual and low flow conditions. We provide an overview of the evolution and ...

  • San Francisco bay area city cleans Mossy mess - case study

    In Contra Costa County, east of San Francisco, we installed an IWS Screen to remove all types of water borne debris including moss, grass, hyacinth and tumbleweeds.   The installation reduces man hours and risk of injury from raking trash racks as well as keeping service lines clear. This project included: Traveling Screen(s) Elevator Pump ...

  • Eight screens for California aqueduct - case study

    The Berrenda Mesa Water Districts’ California Aqueduct pumping station had a massive debris problem, causing high labor costs, injuries and endless headaches — until they contacted International Water Screens. We engineered and installed a large array of moss removal screens. Now: Labor issues resolved, no racks to clean. Pump efficiencies have improved to the point where the project ...

  • Distribution and extraction of chromium from phosphate ore

    Phosphate rocks are a vital and non-renewable resource which is crucial for agricultural uses. However, this raw material contains various contaminants such as Pb, Cr, Cu, Ni and Zn. Among these elements, chromium is considered as an essential micronutrient at low intake levels. Its occurrence in industrial products at higher concentration can cause a potential risk to plants, animals and ...

  • Discharge Measurement in a Short Intake with a Converging Section – a Case Study

    In the context of a planned retrofit and upgrade of the hydropower plant Wettingen, operated by the Elektrizitätswerke Zürich, three intakes were equipped with acoustic transit time flow measuring devices. Since the flow meters are installed in a converging section, downstream of a pier, it became necessary to perform numerical flow simulations in order to weight the acoustic path ...

  • Effects of plumbing systems on human exposure to disinfection byproducts in water: a case study

    Disinfection byproducts (DBPs) in water distribution systems (WDS) are monitored for regulatory compliance, while populations are exposed to DBPs in tap water that may be different due to stagnation of water in plumbing pipes (PP) and heating in hot water tanks (HWT). This study investigated the effects of water stagnation in PP and HWT on exposure and risk of DBPs to humans. Trihalomethanes ...

  • Assessing the potential use of abandoned mining pools as an alternative resource of raw water supply

    The water crisis in the state of Selangor has prompted the state water authority to use water from abandoned mining pools as an alternative resource of raw water supply. In this study, the potential use of the mining pool water has been assessed to evaluate its safe use for potable water consumption, which is the source of raw water to be supplied to water treatment plants. Assessments were ...

  • Guarantee rate of freshwater in a river mouth intruded by saltwater with respect to the joint impact of runoff and tide

    Saltwater intrusion is detrimental to water utilization. It is of vital significance to study the joint impact of runoff and tide on salinity and the risk of saltwater intrusion. To analyze the risk of saltwater intrusion, this paper proposes two concepts: critical runoff–tide level line and guarantee rate of freshwater. Taking Nandu River Estuary in China as a study case, a three-dimensional ...

  • Raw water intake monitoring - Case study

    The Situation Hydrocarbons in municipal water supplies, including fresh water and desalination systems, are commonly limited to less than 1 part per million. Surface water from rivers, lakes, or the sea with marine traffic, nearby pipelines, or regular flooding can be contaminated by hydrocarbons. Freshwater treatment systems can be damaged by hydrocarbons or allow them to pass through ...

  • Determination of total vanadium and vanadium(V) in groundwater from Mt. Etna and estimate of daily intake of vanadium(V) through drinking water

    Vanadium(V) can be found in natural waters in the form of V(IV) and V(V) species, which have different biological properties and toxicity. The purpose of this study was to determine the concentrations of total V and V(V) in groundwater from the area of Mt. Etna and to assess the estimated daily intake (EDI) of V(V) of adults and children through drinking water. Water was sampled monthly at 21 ...
