  • 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 effects of input materials on ceramic water filter efficacy for household drinking water treatment

    Locally manufactured ceramic filters can improve drinking water quality and reduce diarrheal disease burden in developing countries; however, production methods and quality control protocols vary at the >50 factories. We manufactured filter disks with varied clay, burn-out material, burn-out material sieved with different mesh sizes, and burn-out material to clay ratios and calculated ...

  • Adenovirus, MS2 and PhiX174 interactions with drinking water biofilms developed on PVC, cement and cast iron

    Biofilms colonizing pipe surfaces of drinking water distribution systems could provide habitat and shelter for pathogenic viruses present in the water phase. This study aims (i) to develop a method to detect viral particles present in a drinking water biofilm and (ii) to study viral interactions with drinking water biofilms. A pilot scale system was used to develop drinking water biofilms on 3 ...

  • Rapid, specific and quantitative polymerase chain reaction (PCR) detection of pathogenic protozoa Entamoeba histolytica for drinking water supply

    In this study, a quantitative species-specific polymerase chain reaction (PCR) method to rapidly detect E. histolytica in water is developed. First, the specificity of E. histolytica PCR detection was verified by using species-specific primers of 16S-like rRNA genes to clearly differentiate it from the closely related amoebae species E. dispar and E. ...

  • Determination of oil and grease in water with a mid-infrared spectrometer

    The concentration of dispersed oil and grease (OG) is an important parameter for water quality and safety. OG in water can cause surface films and shoreline deposits leading to environmental degradation, and can induce human health risks when discharged in surface or ground waters. Additionally, OG may interfere with aerobic and anaerobic biological processes and lead to decreased wastewater ...
