“…The Wagtech Arsenator field kit uses a battery-operated handheld photometer to read the color stain, for better accuracy and precision. This kit continues to be used by UNICEF to test wells in Bangladesh [24]. It is the lowest cost and most portable and accurate method to determine safe limits of arsenic (WHO guidelines: 0.010 mg·L Elmer Model MHF-10 hydride generator (IMTA, Jiutepec, Mexico).…”

The present study was conducted in Naranjo County located in the municipality of Mixco, Guatemala. The water supply source comes from two wells with a maximum flow of 25.24 and 33.44 L·s . The aim of this study was to conduct laboratory tests, basic engineering and supervision of the construction and evaluation of an operations plant using two configurations, A (low-rate sedimentation and ceramic filter) and B (high-rate sedimentation and clinoptilolite filter), to remove arsenic present in water for human use and consumption. This plant supplies water to Naranjo County in Mixco, Guatemala (5000 inhabitants). First, a laboratory Jar Test was performed to evaluate arsenic removal efficiency. And second, a conventional clarification plant was then built (design flow: 25.24 L·s ) for arsenic, values that comply with Guatemalan standards. For this case, the relation between Fe(III) dosage/mg and As(V) removal was 1:46.

“…The arsenic problem arose with the decision many years ago to stop using surface sources of drinking water and to begin digging millions of tube wells, so called because of their design (3). Although this shift has been accompanied by a decrease in infant mortality from microbial diseases, it has exposed millions to arsenic.…”

“…Some have argued that the lab approach is preferable because it provides better accuracy and can achieve low cost per sample with high throughput. Others contend that the sheer volume of samples to test, long turnaround time, and transport logistics, combined with a lack of facilities and skilled personnel in developing countries, make the laboratory approach unrealistic and the field kits the only feasible solution (3).…”

orldwide, 1.1 billion people lack access to safe drinking water, and 2.4 billion are without basic sanitation, according to estimates by the United Nations (UN).Those are just two of the startling statistics highlighted in Water: A Shared Responsibility, a UN report issued this year (1; Figure 1 on p 5269). The UN General Assembly has declared an "International Decade for Action", with the goal of halving the figures listed above by the year 2015.Every day, ~6000 children around the world die from waterborne illnesses. Arsenic in well water compromises the health of millions. Threats from naturally occurring geological sources add to pressures stemming from population growth, industrial development, mining, and agriculture.All around the globe-developed countries included-we are facing a critical shortage of potable water, explains Mark A.

“…According to WHO guideline, 10 μg L -1 count as a permissible limit for drinking purpose, while the national standard is five times higher (50 μg L -1 ) in Bangladesh (Mosler, 2010). A few studies (Tondel et al, 1999;BGS, 1999;Erickson, 2003) reported that this level has been exceeded with it reaching up to 2000 μg L -1 in many cases.…”

Abstract. This study was performed based on local perception on arsenic toxicity with respect to socioeconomic status at the Achintanagar village in the southwestern part of Bangladesh. The questionnaire was distributed randomly at the local scale in the study area. It was found that the respondents are highly contaminated with arsenic and most of them have suffered from economic crisis and ignorance. Arsenic contamination and food poisoning concept has direct bearing on educational level which is emphasized on socioeconomic status. Correlation coefficient matrix had revealed that the whole aspects of socioeconomic component negatively correlated with arsenic toxicity for group one and two. Female participant were observed to be more unconscious than male respondents on food contamination through arsenic accumulation. Results showed that, most of the respondents continued to eat and practiced the sale of contaminated food in the community. It was observed that this practice is highly contagious for human and environmental health.
