  • 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 ...

  • Effects of sulfate and nitrate on the taste of water: a study with a trained panel

    The role of sulfate and nitrate in the taste of drinking water is not entirely clear. Taste threshold concentrations (TTCs) were estimated for these two species by the 3-AFC method by a trained panel, as sodium and calcium salts. In both cases TTCs for nitrate were about 100 mg NO3/L, twice the usual reference value of international recommendations. TTCs for sulfate were about 160 mg ...

  • Heterotrophic monitoring at a drinking water treatment plant by matrix-assisted laser desorption/ionization–time of flight (MALDI-TOF) mass spectrometry after different drinking water treatments

    The aim of this work was to assess the suitability of matrix-assisted laser desorption/ionization–time of flight mass spectrometry (MALDI-TOF MS) for routine heterotrophic monitoring in a drinking water treatment plant. Water samples were collected from raw surface water and after different treatments during two campaigns over a 1-year period. Heterotrophic bacteria were studied and isolates ...

  • Removing Inorganic Contaminants with Arsenic Water Treatment

    Inorganic contaminants in drinking water are more than just an annoyance. Arsenic is a naturally occurring carcinogen, which is known to lead to both cancer and heart failure. Arsenic is also a difficult contaminant to detect. Since arsenic is both odorless and colorless, testing has to be conducted in order to reliably identify it. Arsenic often appears in conjunction with iron and manganese. ...

  • Why Everyone Should Drink Filtered Water

    Your body is made up of a lot of water; 60 to 65 percent to be exact. The water that you drink each day helps to replenish your body and give you strength. But, if you’re drinking water that contains heavy amounts of chemicals, metals, and other harmful ingredients, what does that say about your body composition? Untreated water could be responsible for a number of different health and ...

  • New technique for direct fluoroimmunomagnetic detection of rotavirus in water samples

    A new rapid, sensitive and selective method for rotavirus detection in water samples is described in this paper. Amino pink magnetic microparticles were functionalized with monoclonal antibodies and used to capture, concentrate, separate and detect infectious rotavirus particles in distilled and drinking water samples. The fluorescence of the microparticles was used to determine the ...

  • Quantitative microbial risk assessment to estimate the health risk from exposure to noroviruses in polluted surface water in South Africa

    This study assessed the risks posed by noroviruses (NoVs) in surface water used for drinking, domestic, and recreational purposes in South Africa (SA), using a quantitative microbial risk assessment (QMRA) methodology that took a probabilistic approach coupling an exposure assessment with four dose-response models to account for uncertainty. Water samples from three rivers were found to be ...

  • Effectiveness of silver and copper infused ceramic drinking water filters in reducing microbiological contaminants

    A series of bench-scale experiments were conducted on ceramic filters with various amounts of silver and/or copper nanoparticles fired-in during the manufacturing process. The experiments were designed to determine the efficacy of the filters on the removal of pathogens from drinking water. Escherichia coli and MS2 were employed as non-pathogenic surrogates for pathogenic organisms. ...

  • The role of bottled drinking water in achieving SDG 6.1: an analysis of affordability and equity from Jakarta, Indonesia

    Bottled water serves an increasingly large percentage of urban poor populations in lower-income countries, yet receives little attention within international development research and policy. This study investigates the impact of packaged drinking water (refill water) on affordability and equity of drinking water access by the urban poor under SDG 6.1, comparing refill water cost and ...

  • Solutions for removing arsenic from drinking water

    Arsenic, a metalloid element, is found in many naturally occurring compounds. In its inorganic form, arsenic is toxic. Arsenic occurs naturally in some groundwater supplies worldwide, including in the drinking water supplies in parts of Taiwan, Japan, Bangladesh, and western South America. This is causing health problems, according to the American Cancer Society. Albuquerque, New Mexico, is the ...

  • Why are drinking water treatment plants in a city important?

    Different natural water bodies and reservoirs are the vital resources of fresh water for the municipal areas. The water collected from the natural water bodies and reservoirs are chemically treated and are made suitable for drinking and other regular activities. Billion litres of water is transmitted from the plants to the municipal sectors. The main target is to provide safe and clean Drinking ...

  • PeCOD® Analyzer oxygen demand analysis for source & treated drinking waters

    MANTECH’s chemical oxygen demand (COD) analyzer is breaking new ground in the science of monitoring source and treated drinking water. In addition to providing 15-minute COD results and biochemical oxygen demand (BOD) estimates, MANTECH’s PeCOD® Analyzer measures natural organic matter (NOM) in raw and treated drinking water. The NOM Analyzer™  — which is the ...

  • Solutions for Safe Drinking Water Through Biological Water Treatments

    Most people across the U.S. expect to turn on their faucets and have immediate access to clean drinking water. The truth is, it wasn’t until 1974 that Congress passed the Safe Water Drinking Act with the goal of regulating the nation’s public water supply. Over the years, the SWDA has been amended to include water sources as well, such as rivers, lakes, springs and groundwater wells ...

  • Using Biological Filtration to Remove Arsenic from Drinking Water

    In 2001, the U.S. Environmental Protection Agency changed the standards for arsenic levels in drinking water. At that time, the agency had estimated that more than 36 million Americans were drinking water that contained arsenic levels at or above 3 parts per billion. A new standard was set, lowering the maximum contaminant level to 10 parts per billion (ppb) from the previous standard of 50 ppb. ...

  • In-situ features of LNA and HNA bacteria in branch ends of drinking water distribution systems

    The knowledge of bacteria with low or high nucleic acid (LNA or HNA, respectively) content was relatively limited in drinking water distribution systems (DWDSs). In the present study, LNA and HNA bacterial growth characteristics and effect of water physicochemical properties on these two subgroups were analyzed at the branch ends of a DWDS. The results showed that LNA bacteria were in the ...

  • The risk of cancer as a result of elevated levels of nitrate in drinking water and vegetables in Central India

    The objective of the present study was to determine the effect of nitrates on the incidence of gastrointestinal (GI) cancer development. Nitrate converted to nitrite under reducing conditions of gut results in the formation of N-nitrosamines which are linked to an increased gastric cancer risk. A population of 234 individuals with 78 cases of GI cancer and 156 controls residing at urban and ...
