  • Treatment of Arsenic Contaminated Industrial Wastewaters

    Arsenic in industrial wastewater effluents is attracting greater regulatory attention. Depending on factors such as total maximum daily loads (TMDLs), the National Pollutant Discharge Elimination System (NPDES) discharge permit levels for arsenic may even be less than the drinking water standard of 10 µg/L. One of the industries affected by stringent arsenic discharge limits is coal-fired power ...

  • Slow arsenic poisoning of the contaminated groundwater users

    This paper gives impact of Arsenic contaminated water on human health as well as overview of the extent and severity of groundwater arsenic contamination in Bangladesh. Scalp hair is the most important part of the human body to monitor the accumulation of this type of poison. Therefore, an experiment has been carried out by Neutron Activation Analysis (NAA) at Atomic Energy Research Establishment ...

  • Characterisation of arsenic contamination in groundwater by statistical methods

    Statistical investigation on groundwater arsenic concentration data of southwest Bangladesh was performed. Two data sets of 1998–99 and 2002–03 were selected for this analysis. Summary statistics of the data shows that the mean concentration exceeds the Bangladesh limit (0.05 mg/l) in all areas. Normality of arsenic concentration data was checked by frequency histogram, skewness coefficient and ...

  • 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. ...

  • Plant algae method for arsenic removal from arsenic contaminated groundwater

    Field studies were carried out in Urumqi River Basin in Northwest China. The study focused on experimentation on a plant algae method that was tested by taking various water chemistries into consideration. The results from a greenhouse experiment evaluated for four doses of P (0, 100, 200, and 300 μmol/L) using two ferns (30 and 60 day old) on 15 L of contaminated groundwater per plant revealed ...

  • A Trace of Arsenic

    The cans of baby formula invaded Brian Jackson’s Dartmouth College lab late in 2010. His team picked up an armful of popular brands at the food co-op in Hanover, N.H. Then another armload. Eventually Jackson had a cabinet full of the brightly labeled canisters. Today, he still keeps a few in his office. Not as clutter — that’s not his style. He just likes to keep his toxicology ...

  • Stanford Researchers Link Aquifer Overdraft to Arsenic Contamination

    In a recent study, researchers used satellite data to establish a link between excessive pumping from California aquifers and dangerous arsenic concentration spikes in the groundwater of the Tulare Basin. This promises to be an important early warning system for the growing problem of arsenic contamination, which potentially threatens ...

  • Health and socioeconomic effects of groundwater arsenic contamination in rural Bangladesh

    This report discusses the health and socioeconomic problems that have recently emerged in the Bangladesh countryside because of arsenic contamination of the groundwater. A survey found that men in rural households are generally found to be more susceptible to arsenicosis than women. The survey also indicated that villagers with lower annual income are more likely to experience arsenicosis. About ...

  • Human health risk assessment of an arsenic contaminated golf course

    St Michael’s Jubilee Golf Course in Widnes was constructed between 1964 and 1986, by re-grading chemical waste deposits generated from local industries, which were then covered with a thin layer of topsoil and grassed over.  An estimated 4.5 million tonnes of waste materials are present beneath the golf course.  The site is underlain by alluvium and a major aquifer, the Sherwood ...

  • The fate of arsenic in contaminated paddy soil with gypsum and ferrihydrite amendments

    Ferrihydrite and gypsum (CaSO4·2H2O) are two chemicals which were suggested to reduce the bioavailability of arsenic (As) in agricultural field. The efficiency of those chemicals added in the paddy field was investigated by pot culture in this study. The results showed As uptake by rice under ferrihydrite treatment was significantly ...

  • Arsenic Treatment-Michigan

    In May, 2003, upon approval by the County Health Department, Adedge Technologies in conjunction with its Michigan representative Artesian, Inc. installed the first arsenic treatment system for a Type II non-transient, noncommunity (NTNC) water system in Oakland County, Michigan. The 40 gallon per minute (gpm) system was installed at an elementary school serving 600 students to reduce naturally ...

  • Toxic injustice in the Bangladesh water sector: a social inequities perspective on arsenic contamination

    Arsenic contamination of groundwater in Bangladesh poses a major environmental health hazard to millions. The efforts of public health programmes to address the problem have often been short-lived and unevenly distributed. The crisis represents a failure of governance and a structural injustice of global dimensions. Rights-based approaches to development have been proposed to address such ...

  • Arsenic contamination and its causative factors in parts of Chhattisgarh, Central East India

    This paper reports the present status of ground water arsenic contamination in the parts of Ambagarh Chowki block in District Rajnandgaon, of Chhattisgarh State. This location is the first arsenic contaminated location reported outside Bengal Delta Plain. The analysis of arsenic contamination measured during year 2008 to 2009 is compared with previously reported synoptic sampling results. This ...

  • Efficacy of arsenic filtration by Kanchan Arsenic Filter in Nepal

    Groundwater arsenic contamination has caused a significant public health burden in lowland regions of Nepal. For arsenic mitigation purposes, the Kanchan Arsenic Filter (KAF) was developed and validated for use in 2003 after pilot studies showed its effectiveness in removing arsenic. However, its efficacy in field conditions operating for a long period has been scarcely observed. In this study, ...

  • Spatial pattern of arsenic contamination in shallow wells of Bangladesh: regional geology and nonlinear dynamics

    Since the discovery of large-scale arsenic contamination of groundwater in Bangladesh more than a decade ago, studies related to its spatial characterization have relied on geostatistical approaches and the classical notion of linear stochastic dynamics. This study explores an alternative nonlinear approach, with a motivation to possibly achieve more cost-effective solutions for Bangladesh. It ...

  • Potential for arsenic contamination of rice in Bangladesh: spatial analysis and mapping of high risk areas

    Knowledge of the location and severity of arsenic contamination in Bangladesh is required to develop land and resource management strategies to reduce human exposure to arsenic and arsenic contamination of food and water supplies. Potential high risk areas for arsenic contamination of rice were identified using spatial analysis and modelling. Existing country-wide data on groundwater arsenic ...

  • Removal of arsenic from contaminated groundwater with application of iron electrodissolution, aeration and sand filtration

    The results from a new water treatment system for arsenic removal are presented. The technology is based on the employment of an electrolytic iron dissolution and efficient aeration procedure prior to sand filtration. The treatment was introduced and investigated in a pilot scale plant and full scale waterworks. The pilot scale results showed the potential for efficient arsenic removal from ...

  • Treatment of arsenic-contaminated water using in-line electrolysis, co-precipitation and filtration in Costa Rica

    A novel treatment was tested with groundwater to investigate its arsenic removal under natural conditions. The system utilised in-line electrochlorination to oxidise water constituents without the need for external chemical supply. The oxidised arsenic and iron co-precipitated and were filtered via Greensand Plus™. The filter was catalytically active and provided an emergency oxidant. The ...
