  • 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 ...

  • 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 ...

  • The impact of low-flow season on source drinking water quality, Rosetta branch, Egypt

    The present work was conducted to document the problems raised regarding low-flow in the Rosetta branch, Egypt and to develop management options to protect drinking water sources. The water quality was monitored during low-flow periods at four drinking water intakes. Results showed an increase in electric conductivity (EC), ammonium (NH4), nitrite (NO2), phosphate (PO4), and ...

  • 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. ...

  • 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 ...

  • MYTH vs TRUTH: “If my disinfectant residual is always high enough, I don’t have to worry about microbes”

    Monitoring disinfectant residuals (i.e. Free and Total Chlorine and/or Chloramine concentration) is one of the most essential practices in drinking water management programs.  This ensures that sufficient protection is maintained at all points in the distribution system.  The absence of a disinfectant residual means that suppression of microbiological growth is much more difficult and ...

  • This polluted lake shows why we are all stakeholders when it comes to clean water

    When environmental protection gets short shrift, the price we pay can be staggering. When I visited Onondaga Lake in 1999 as part of research I did as a student at Cornell, there was no evidence the lake was once home to vibrant waterfront resorts. Yet, in the late 1800s and early 1900s, Onondaga was considered “ ...

  • Statistical assessment of water quality of a Ramsar site wetland

    This study was conducted to evaluate the wetland water quality (WWQ) over a period of 3 years and establish relationships between these qualities using Ramsar site Uchali Wetland, Pakistan (32 °33′N, 72 °01′E). WWQ data obtained were subjected to summary statistics, generalized linear model (glm), correlation, covariance and cluster analysis. The glm of the monthly mean water indices showed ...

  • Guide to Removing Arsenic from Drinking Water

    It’s said that the human body is made up of almost 60 percent water. Is the water you’re putting into your body pure? Many people are unaware of the chemicals and compounds that are seeping into their drinking water and wreaking havoc on their internal systems. Arsenic, for example, can be found in many different areas. In the Northeast especially, well water is more likely to be ...

  • Nitrate Analysis of Water Samples Using a Benchtop UV-Vis Spectrophotometer

    Nitrogen is naturally found in groundwater and surface water in the form of nitrate, nitrite, or ammonium. The EPA has established a maximum contaminant level of nitrate-nitrogen in potable water of 10ppm. This application presents results of UV-Vis analysis of nitrate concentrations in drinking water, ground water, and industrial wastewater, showing that the manual colorimetric method is ...

  • The Benefits of Biological Treatment for Drinking Water

    The biological treatment of drinking water is undertaken using both organic and inorganic contaminants, and can be used to treat groundwater and surface water. These contaminants, contrary to what the name implies, are applied to strip away the factors that make the water unsafe for drinking until it is potable—meaning drinkable. If you would like to learn more about the benefits of ...

  • The effect of human activities on the pollution of water in southwest Giza area, Egypt

    Southwest Giza area is one of the most complicated regions in Egypt because of the combination of agricultural, industrial and urbanization activities with few studies about water resources contamination with heavy metals. In this study, ten surface water samples and eight groundwater samples were collected and analyzed for pollution with Fe, Mn, As, Cr, Cd, Pb and Cu. The samples were ...
