  • Rapid quantification of bacteria and viruses in influent, settled water, activated sludge and effluent from a wastewater treatment plant using flow cytometry

    As microbiological parameters are important in monitoring the correct operation of wastewater treatment plants and controlling the microbiological quality of wastewater, the abundances of total bacteria (including intact and damaged bacterial cells) and total viruses in wastewater were investigated using a combination of ultrasonication and flow cytometry. The comparisons between flow cytometry ...

  • Cost-Benefit Analysis of Urban Stormwater Retrofits and Stream Daylighting Using Low Impact Development Technologies

    ABSTRACTThis project incorporates Low Impact Development (LID) concepts into the City of Caldwell (Idaho) Indian Creek daylighting and downtown redevelopment project, which is a prime candidate for a “showcase” project producing benefits in urban runoff within the lower Boise River watershed. The primary goal of this project was to incorporate LID concepts into the Indian Creek daylighting ...

  • Advanced Water Quality Techniques Course

    Abstract:The development of a strategic water quality monitoring program is based on prioritizing risks to public safety and economic reality. The development of global standardized methods and protocols for automated water quality monitoring would facilitate international communication of water quality information and comparison of standardized methods and protocols. The three primary methods ...


  • ASTM Standards Help Meet Need for Clean Water

    The new ASTM Water Portal provides a single access point to standards and related information about ASTM International’s diverse committees working to protect and monitor this vital global resource. Clean and safe water is the underpinning of the quality of life for people around the world. Global economies depend on water, whether it’s to support the manufacturing of goods ...

  • Genetic diversity of Escherichia coli isolates from surface water and groundwater in a rural environment

    The genetic characteristics among Escherichia coli strains can be grouped by origin of isolation. Then, it is possible to use the genotypes as a tool to determine the source of water contamination. The aim of this study was to define water aptitude for human consumption in a rural basin and to assess the diversity of E. coli water populations. Thus, it was possible to ...

  • Continuous Modeling of Wet Weather Strategies Annual Water Quality Results Support a Municipality’s Decision-Making Process

    ABSTRACTAn extensive water quality modeling effort for the City of Columbus Long Term Control Plan (LTCP) was performed in order to evaluate future scenarios to abate combined sewer overflows. This modeling effort was supported by a massive data collection program and employed three different models to analyze the receiving streams. Once the models were selected and calibrated, continuous annual ...

  • Our drinking water systems are a disaster. What can we do?

    In the wake of the Flint, communities turn to innovative technology and financing to prevent the next crisis. People in developed countries turn on the tap and safe drinking water flows, a dramatic health benefit they tend to take for granted. That complacency was dramatically disrupted last year when children in Flint, Michigan, started testing positive for lead poisoning and the ...

  • Dyed viruses and metal particles for advanced separation studies

    Single nanometer sized particles are poorly retained by conventional water treatment methods and are hardly detectable in water samples. The particles present a separate class of pollutants and their transport and fate cannot be studied by tracking bacteria, turbidity, free dyes or ions. Dyed bacteriophages and gold nanoparticles are two novel tools that facilitate the studies of virus ...

  • Sorbitol-fermenting Bifidobacteria are indicators of very recent human faecal pollution in streams and groundwater habitats in urban tropical lowlands

    Sorbitol-fermenting Bifidobacteria (SFB) proved to be an excellent indicator of very recent human faecal pollution (hours to days) in the investigated tropical stream and groundwater habitats. SFB were recovered from human faeces and sources potentially contaminated with human excreta. SFB were undetectable in animal faeces and environmental samples not contaminated with human faeces. Microcosm ...

  • Scientists study DNA in wastewater to protect public health

    An interdisciplinary team of researchers from Stanford University is working on methods to monitor wastewater for the DNA of pathogens such as the flu and other viruses. This could help health agencies prepare early for a disease outbreak instead of waiting until disease symptoms are reported, but for some people is harder to present symptoms since they take health supplements from healthyusa.co ...

  • Types of bioremediation and their modes of action

    An Urgent Call for Change in U.S. Oil Spill Response With Bioremediation Agent Type EA* bearing out as a workable first response alternative to the use of chemical dispersants, contrasting evidence has become even clearer that dispersant use has been a huge failure. Dispersants have proven to be an inadequate response method with more and more studies showing an ...

  • Simon Fraser University Opens Suite of Mass Spectrometers for Natural Products Discovery Research

    As a graduate student at the University of British Columbia, Dr. Roger Linington discovered his future life’s work serendipitously. While studying sponges, it became clear to him that one of the challenges in studying macroorganisms is their limited or slowly replenishing supply. To perform mechanism and mode-of-action studies, he needed a larger, more accessible source of ...

  • Smart Series-Odor Management

    Tackling odors at composting facilities is a manageable task made simpler by inventorying and treating all sources and tapping into technology advances. Perhaps one of the most difficult realities that had to be faced 15 to 20 years ago by the composting universe is that the phrase, “odor-free” - at least when it comes to composting - is probably an oxymoron. Feedstocks that biodegrade within the ...

    Inspecting Reservoirs – what is the importance of them, why they are inspected, and how ROVs help pave the way for low-cost, regular maintenance. What is a Reservoir? Deriving from the French word réservoir meaning “storehouse,” a reservoir is exactly that – a storage place for water. More often than not, these bodies of water are ...

    A. SOLARBEE OVERVIEW 1. Origin of the SolarBee. Pump Systems, Inc. (PSI) developed, built and installed its first solar powered mixer in Dickinson, ND, in the summer of 1998. It was installed into a 30 acre x 13 foot deep municipal wastewater reservoir which had a long history of toxicity associated with ammonia, odor, and stratification problems. In six weeks the entire reservoir cleared up to ...
