  • 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 ...

  • Moringa oleifera functionalised sand – reuse with non-ionic surfactant dodecyl glucoside

    Moringa oleifera seeds are well known for their ability to cause flocculation in turbid water and facilitate bacterial inhibition. These effects are due to the cationic polypeptide MO2.1, which affects the surface charge of suspended particles and causes lysis of bacterial cells. However, the attachment of bacteria to MO2.1 prevents further bacterial attachment, ...

  • 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 ...

  • 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 ...

  • Bioremediation of pollutant-contaminated water

    Raw water resources in Kafr El-Sheikh Governorate are affected by many contaminants particularly during the winter season and low demand period of the Nile River, in which water level decreases and organic matter increases resulting in decreased dissolved oxygen, and increased ammonia, nitrite and bacterial load in the water. In this study, physicochemical and microbiological characteristics ...

  • Preliminary results of water quality assessment using phytoplankton and physicochemical approaches in the Huai River Basin, China

    Water pollution has been a significant issue in the Huai River Basin (HRB) of China since the late 1970s. In July and December 2013, two field investigations were carried out at 10 sites along the main streams of the basin. The monitoring indices contained both physicochemical variables and the structure and composition of phytoplankton communities. The correlations between communities and ...

  • 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 ...

  • In the depths of the oceans, human activities are beginning to take their toll

    Once seen as too remote to harm, the deep sea is facing new pressures from mining, pollution, overfishing and more. Imagine sinking into the deepest parts of the Central Pacific Ocean, somewhere between Mexico and Hawaii. Watch as the water turns from clear to blue to dark blue to black. And then continue on for another 15,000 feet (4,600 meters) to the seafloor — roughly 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 ...

  • Norwegian study on microbial source tracking for water quality control and pollution removal in constructed wetland treating catchment run-off

    This study describes the first Norwegian microbial source tracking (MST) approach for water quality control and pollution removal from catchment run-off in a nature-based treatment system (NBTS) with a constructed wetland. The applied MST tools combined microbial analyses and molecular tests to detect and define the source(s) and dominant origin(s) of faecal water contamination. Faecal ...

  • Experimental study on performance of sand filter layer to remove non-point source pollutants in rainwater

    Clogging characteristics of conventional sand filter layers with different grain-size distributions were experimentally studied to estimate their filtration capacity to capture non-point source pollutants in an artificial rainwater reservoir. A series of laboratory-scale chamber tests was conducted for artificial urban runoff synthesized with non-point source pollutants collected from a real ...

  • Joint occurrence of water quality indexes in relation to river streamflow in the heavily polluted Huai River Basin, China

    Effective joint management of water quantity and quality of rivers requires a good understanding of the interrelationships between these variables. This study aims to quantitatively evaluate the impact of river streamflow on the joint occurrence of water quality variables in the heavily polluted Huai River Basin (HRB). Using data from three representative stations, joint distributions were set ...

  • Assessing the abatement potential and cost of Chinese industrial water pollutants

    Water pollution is becoming an increasing threat to China's sustainable development. To respond to this challenge, China has pledged to cut emissions of two major water pollutants, chemical oxygen demand (COD) and ammonia nitrogen (NH4), and has disaggregated the national target among provinces. However, the abatement potential and costs have not been thoroughly assessed. This paper aims to ...

  • 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 “ ...

  • 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 ...

  • 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 ...
