  • European water policies and human health — Combining reported environmental information

    Society depends on the satisfactory and sustainable management of water. Historically, the primary purpose of water treatment was to protect human health, through reducing disease being transmitted through water. Subsequent measures to address environmental concerns have broadened our expectations of what water and waste water treatment should deliver. This report considers three pieces of EU ...

  • Water, water everywhere: But is there enough to drink?

    Original story at MIT News At MIT, experts address the challenges of supplying clean, safe water to a growing world population. The challenge of supplying clean, safe drinking water to an expanding world population comes down to money, MIT economist Franklin Fisher ...

  • The Future of Drinking Water

    Predicted future growth in population numbers and rising sea levels mean demand for drinking water will continue to increase just as the natural availability of freshwater decreases. It is likely that brackish groundwater will be an important source of drinking water in the future, but the current methods used to produce fresh water from this source are expensive in terms of their energy use and ...

  • Linking drugs of abuse in wastewater to contamination of surface and drinking water

    The concentrations of 17 drugs of abuse, including cocaine, several amphetamines, opioid drugs, and 2 metabolites—benzoylecgonine, a metabolite of cocaine, and 2‐ethylidene‐1,5‐dimethyl‐3,3‐diphenylpyrolidine, a metabolite of methadone—were investigated in an urban watershed that is heavily impacted by discharges of municipal wastewater. The artificial sweetener sucralose was also monitored as ...

  • Comparison of three methods to concentrate Giardia cysts and Cryptosporidium oocysts from surface and drinking waters

    In this study, three methods commercialized by Pall (Envirochek HV), Idexx (FiltaMax) and Whatman (Cryptest) to concentrate Giardia cysts and Cryptosporidium oocysts from surface and drinking waters were compared according to the EPA standard protocol. Twenty litres of surface and 100 litres of drinking waters were inoculated with 103 (oo)cysts before being concentrated by ...

  • Monitoring Nitrates in Drinking Water and Wastewater

    Nitrate is present in high levels in wastewater due in part to the high nitrates present in human sewage but also from some types of industrial effluent entering the municipal sewer system. Nitrate is also a very common contaminant in both surface water and ground water. Nitrate occurs naturally in source water as a result of decaying plants. However, there are other manmade sources of ...

  • Crossville, TN, municipal drinking water

    The Situation: The City of Crossville, Tennessee, needed to address increasingly strict regulations on the use of gas chlorine to disinfect their community’s water. The Solution: By switching from gas chlorine to MIOX mixed oxidants, the City has reduced operational costs, improved residual durability, reduced byproduct formation, produced longer filter ...

  • Adsorption of fluoride from water by surface-functionalized polyurethane foam

    Surface-functionalized polyurethane foam (SPUF) showed an exceptionally high adsorption potential for defluoridation of drinking water. Kinetic experiments of fluoride adsorption on SPUF demonstrated quick adsorption in first 60 min and then achieved maximum adsorption (7.8 mg  g−1). The adsorption isotherm was described using Bradley equation. The adsorption capacity of SPUF was significantly ...

  • Removal of DOC and DBP Precursors from a Surface Water Supply

    Background: The 2.5 MLD Airey’s Inlet Water Treatment Plant is conventional alum coagulation, sludge blanket clarification, filtration WTP. It sources raw water from the 514 ML Painkalac Dam situated in the Angahook State Park This raw water is soft and high in colour and dissolved organic carbon (DOC). After heavy rainfalls, colour and DOC content are known to further increase along with a spike ...

  • Fresh Ideas for Fresh Water: Okeechobee Utility Authority`s Surface Water Treatment PLant Uses Innovative Technology to Achieve High Quality Drinking Water from Lake Okeechobee

    ABSTRACTThe goal of this project was to expand Okeechobee Utility Authority’s (OUA) Surface Water Treatment Plant while meeting the challenges of limited space, raw water quality, available capital, and new EPA regulations. The preliminary engineering, consisting of site visits, pilot studies, and research, resulted in an innovative design for surface water treatment. This design combines several ...

  • Feasibility assessment of surface water disinfection by ultrafiltration

    Ultrafiltration (UF) has been presented as an alternative to chemical disinfection to obtain safe drinking water, for its ability to remove microbiological contamination. Hollow-fiber UF membranes are designed as an effective barrier to microorganisms, for their high manufacturing integrity and for the ‘potting’ method adopted to seal fibers to the feeding/extraction manifold. ...

  • Rapid Quantification of Perfluorinated Compounds in Drinking and Surface Water Using LC-MS/MS

    As contaminants of emerging concern, research on PFCs is ongoing to determine the impacts of these materials on human health and the environment. A CDC study detected four of these analytes in >98% of serum samples representative of the general US population above age twelve. Low level analysis of these compounds is challenging due to their ubiquitous presence in the laboratory and analytical ...

  • The effect of the surface-to-volume contact ratio on the biomass production potential of the pipe products in contact with drinking water

    The biomass production potential (BPP) test is a semi-static test for assessment of microbial growth promoting properties of construction products in contact with drinking water (CPDW). In 2003 the test was selected for incorporation into a scheme for acceptance of CPDW in the framework of implementation of the European Construction Product Directive and Drinking Water Directive. The pass/fail ...

  • Influence of Copper Mine on Surface Water Quality

    Aras water basin is located in northwest of Iran. Sungun mine which is the largest open-cast copper mine of Iran is located in this region and is in the primary stages of extraction. The influence of mining activity on the quality of regional surface water has been taken in to consideration in this study. Accordingly, sampling was done from 5 local streams in the study area. In order to consider ...

  • Application of the membrane technology to control ammonia in surface water

    Amnonium ion is effectively removed by Reverse Osmosis membranes (Brackish water, BW; Saline water, SW). The removal efficiency of ammonium ion from a solution containing ammonium ion which is not complexed is varying in the range of 5–60%. On the contrary, ammonium ion forms complexes with other ions in water and wastewater removal efficiency was as high as 99% for the synthetic solution which ...

  • Oxidation and volatilization of bromide by electrolysis in drinking water

    To reduce the concentrations of brominated disinfection by-products, a process is presented here which removes bromide from a widely used surface water source, the California State Water Project (SWP). The process consists of oxidizing bromide to bromine and volatilizing the bromine. SWP water was passed through this unit under various conditions and the bromide was oxidized and volatilized under ...

  • Impact of plumbing age on copper levels in drinking water

    Theory and practical experiences suggest that higher copper levels in drinking water tap samples are typically associated with newer plumbing systems, and levels decrease with increasing plumbing age. Past researchers have developed a conceptual model to explain the ‘aging effect’ founded in the proposed evolution of copper(II) corrosion by-products on the pipe surface, based on theoretical ...

  • Perceived agricultural runoff impact on drinking water

    Agricultural runoff into surface water is a problem in Australia, as it is in arguably all agriculturally active countries. While farm practices and resource management measures are employed to reduce downstream effects, they are often either technically insufficient or practically unsustainable. Therefore, consumers may still be exposed to agrichemicals whenever they turn on the tap. For rural ...
