  • Why You Should Monitor Groundwater?

    What is groundwater? Groundwater is water that is stored below the earth’s surface. When rain or other sources of water come into contact with the ground, the majority of it travels below the surface. Though much of this moisture is then absorbed by plants or returned to the atmosphere (through infiltration), some water will travel deeper beneath the surface – where it ...

  • Why Interactive Ultrasonic Programs are Important to Effectively Control Algae

    Many different algal types can bloom in a water body. Some of these algae are plant cells, while others are bacteria. Algae may vary in size, shape and cell characteristics. Typically, the type of algae that blooms depends on water temperature and sun hours. As a result, algal types may change several times during a season. To effectively  ...

  • Ultrapure Water for Determination of Toxic Elements in Environmental Analyses

    Abstract In this paper the importance of reagent water quality for toxic element environmental analyses is discussed, and the suitability of fresh ultrapure water produced using Merck water purification systems for ICP-OES and ICP-MS trace element analyses in environmental laboratories is demonstrated. Key words or phrases Trace elements, metals, toxic ...

  • The Water Quality Association comes to Denver

    Purolite representatives from Canada as well as the Midwest and Northeast regions of the United States spent a few days in Denver to support the Water Quality Association (WQA) at their annual meeting. The WQA has been holding this event for its members for more than many decades and Purolite has been a part of the exhibition floor for several years. Visitors from across the globe were in ...

  • Water quality testing: solutions from catchment to waste

    Globally, over 80% of the wastewater generated by society flows back into the environment without being treated or reused.1Clean water is an essential part of daily life, from catchment all the way through to wastewater treatment, therefore analysis throughout the whole cycle ...

  • Algae control in Auckland Dam - Case Study

    Five solar-powered algae control systems where installed in the Lower Nihotupu Dam in Auckland, New Zealand to reduce the levels of blue-green algae. The project started in December 2016 and so far, the project appeared to be of great success with the blue-green algae count over summer 90 per cent less than the previous year. The Challenge: Reduce Blue-green Algae Count The ...

  • Validation of Salt Water Disposal Well Treatment Plants with Handheld Oil in Water Sample Analyzer

    Salt Water Disposal (SWD) well operators often dispose a substantial volume of oil inadvertently when injecting salt water, thereby losing the opportunity to sell the oil on the market and potentially reducing the ability to inject water in the well. Injection facilities are typically operated with minimal instrumentation or system optimization, which means the operators don't know how much, or ...

  • Assessing the spatial pattern of iron in well water from a small central Florida community

    Iron is one of the most common elements in the Earth's crust, which corresponds to it being a common constituent in drinking water supplies. Residents of Bithlo, an unincorporated community in east-central Florida, have observed that their drinking water tastes like metal and stains clothing and teeth. An evaluation of water samples collected from over 200 private drinking water wells revealed ...

  • Sodium hypochlorite dosage for household and emergency water treatment: updated recommendations

    Household water treatment with chlorine can improve the microbiological quality of household water and reduce diarrheal disease. We conducted laboratory and field studies to inform chlorine dosage recommendations. In the laboratory, reactors of varying turbidity (10–300 NTU) and total organic carbon (0–25 mg/L addition) were created, spiked with Escherichia coli, and dosed with 3.75 mg/L ...

  • How to identify issues in water quality

    Water quality can mean different things to different people and therefore depends on what standard of quality one is looking for, for example, water may be fine for fish to live in but lack the quality required for human consumption. To measure the quality of water accurately, tests are carried out to identify several key indicators. These characteristics are then compared ...

  • Sample preparation is the key to quality analysis with a laser analyser

    Sample preparation is the most important step of any chemical analysis. To get the best results with any elemental alloy analyser regardless of the technology, the sample must be clean before taking a measurement. Otherwise the results are always compromised at least to some extent. The effect of dirty surfaces will vary and some technologies are more forgiving to sample surface conditions than ...

  • Viruses in the environment – presence and diversity of bacteriophage and enteric virus populations in the Umhlangane River, Durban, South Africa

    Due to the continued persistence of waterborne viral-associated infections, the presence of enteric viruses is a concern. Notwithstanding the health implications, viral diversity and abundance is an indicator of water quality declination in the environment. The aim of this study was to evaluate the presence of viruses (bacteriophage and enteric viruses) in a highly polluted, ...
