  • Development of Water Quality Test Kit Based on Substrate Utilization and Toxicity Resistance in River Microbial Communities

    Methods for measuring toxicity or respiratory activity of microbial cultures can be used as tools for assessing the presence of chemicals and their impact on the streams. The proposed toxicity test is based on the respirometric characteristics of the bacteria according to the principals of Biolog’s microplate system. As the microorganism ...

  • Care Oxfam-DelAgua Kit Case Study - Yemen

    Generally water quality testing is done to monitor the maintenance and operation of drinking water systems. In Yemen CARE uses the DelAgua water testing kit (developed by OXFAM, reproduced by the Robens Centre for Public and Environmental Health, Surrey University) as an awareness tool to improve the understanding of ‘clean and safe water’ in village communities. “We have ...

  • Comparison and verification of four field-based microbiological tests: H2S test, Easygel®, Colilert®, Petrifilm™

    The UN defines water supplies as ‘improved’ or ‘unimproved.’ These indicators are easy to measure, but do not reflect water quality, which requires laboratory or field tests. Laboratory and test availability, expense and technical capacity are obstacles for developing countries.This research compares and verifies four low-cost, field-based microbiological tests: the EC-Kit (Colilert® and ...

  • Preventative control of legionella through real-time bioburden testing

    Abstract: Of the 485,000 annual cases of pneumonia-like sickness in the USA, approximately 15% are attributed to Legionnaire’s Disease. This typically results in  health care costs of over $600 million (1, 2, 3). For the most part, these incidents can be prevented through effective monitoring and treatment. Since Legionella thrive within microbial biofilms and ...

  • The DNA Revolution for Water Professionals

    Imagine trying to solve a problem when you are provided just 1% of the total data. This is essentially the case in analyzing water and wastewater microbiomes. Conventional microbiological testing methods such as culture and microscopy can identify only about 1% of microorganisms that are contained in a ...

  • The Water Conditions in Ethiopia, Part One

    In August, I was able to visit northern Ethiopia to look at some of the drinking water issues. As you might guess, there are many, ranging from polluted water to almost no water at all. That made it interesting to discover the inhabitants of Adwa and Aksum rely on a reservoir. The reservoir water is treated first by aeration to oxidize iron, then with a flocculant which attracts dirt like a ...


  • The Water Conditions in Ethiopia, Part Two

    While in Ethiopia in August to learn more about what they do about drinking water, I visited the Debre Damo Monastery. About 1,600 years old, it is situated on a flat-topped outcropping of solid rock. The only way in or out is by climbing a sheer cliff using a 15 meter rope made from woven rawhide. The top supports a community of about 150 monks. Certainly the most extreme location I found people ...


  • Things You Should Know about Your Reusable Water Bottle

    Reusable water bottles are everywhere; on office desks, in gym bags, and in kids’ backpacks. And while it’s inexpensive, environmentally friendly, and incredibly convenient to stop by any tap or fountain for a quick refill, there are a few things to remember about these reusable bottles. Actually, there are a few things to remember about microorganisms: many of them love warmth, ...

  • Evaluation of DNA extraction methods and dilution treatment for detection and quantification of Acanthamoeba in water and biofilm by real-time PCR

    Acanthamoeba, human pathogens and natural hosts of pathogenic bacteria, may be accurately detected and quantified by real-time PCR if Acanthamoeba DNA are properly extracted and PCR inhibitors are effectively eliminated. However, the optimization of DNA extraction methods has not been reported for Acanthamoeba. This study compared the effectiveness of two DNA extraction/purification methods ...

  • What classifies as water pollution and why is it an issue?

    The UN declared 2005-2015 as the International Decade for Action ‘Water for Life’. Yet each day thousands of people still die as a result of contaminated water. This does not even take into account the millions of organisms that perish every year thank to polluted water sources. Water pollution is a huge issue that is made more so by the fact that unfortunately, water is ...

  • CH#835 - Grease Removal

    The problem of degrading 6,000+ ft of grease daily has an easier solution than thought at the 27 MGD a Massachusetts Waste Water Treatment Plant. 'At one time, the plant had more grease in its scum pits than it could handle,' said an  engineer . 'Worse yet, there was nowhere to put it. Local landfills stopped accepting greasy solids.' Now the plants grease problem has been virtually solved. ...

  • Tile Cleaning Equipment with Vacuum Extraction Feature

    Ask most contractors what they require with their tile cleaning equipment and they would reply - productivity. Without a machine that offers high output, your business could fail. Tiles can be very hard to clean. Soap scum, water stains, molds, food stains, and other impurities accumulate on tiles quickly. In commercial kitchens and public restrooms especially, dirt accumulates on tile very fast. ...
