Contaminant Level

The current United States maximum contaminant level for arsenic in drinking water is set at 50 μg/l. Because of the cancer risks involved, Canada has already lowered the maximum contaminant level to 25 μg/l; the United States Environmental Protection Agency is reviewing the current allowable level for arsenic with a view of lowering it significantly. Various treatment methods have been adopted to remove arsenic from drinking water. These methods include 1) adsorption-coprecipitation using iron and aluminum salts, 2) adsorption on activated alumina, activated carbon, and activated bauxite, 3) reverse osmosis, 4) ion exchange and 5) oxidation followed by filtration. Because of the promise of oxidation-filtration systems, column studies were conducted at the University of Regina to examine oxidation with KMnO4 followed by filtration using manganese greensand and iron-oxide coated sand to examine the removal of arsenic from drinking water; these results were compared with the data from ion exchange studies. These studies demonstrated that As (III) could be reduced from 200 μg/l to below 25 μg/l by the manganese greensand system. In the case of manganese greensand filtration, addition of iron in the ratio of 20:1 was found necessary to achieve this removal.

Group Resistance

All known societies exclude and stigmatize one or more minority groups. Frequently these exclusions are underwritten with a rhetoric of disgust: people of a certain group, it is alleged, are filthy, hyper-animal, or not fit to share such facilities as drinking water, food, and public swimming pools with the ‘clean’ and ‘fully human’ majority. But exclusions vary in their scope and also in the specific disgust-ideologies underlying them. In this volume, interdisciplinary scholars from the United States and India present a detailed comparative study of the varieties of prejudice and stigma that pervade contemporary social and political life: prejudice along the axes of caste, race, gender, age, sexual orientation, transgender, disability, religion, and economic class. In examining these forms of stigma and their intersections, the authors present theoretically pluralistic and empirically sensitive accounts that both explain group-based stigma and suggest ways forward. These forward-looking remedies, including group resistance to subordination as well as institutional and legal change, point the way towards a public culture that is informed by our diverse histories of discrimination and therefore equipped to eliminate stigma in all of its multifaceted forms.

Lead Levels

BackgroundAlthough patients with kidney disease may be particularly susceptible to the adverse health effects associated with lead exposure, whether levels of lead found commonly in drinking water are associated with adverse outcomes in patients with ESKD is not known.MethodsTo investigate associations of lead in community water systems with hemoglobin concentrations and erythropoietin stimulating agent (ESA) use among incident patients with ESKD, we merged data from the Environmental Protection Agency (EPA) Safe Drinking Water Information System (documenting average 90th percentile lead concentrations in community water systems during 5 years before dialysis initiation, according to city of residence) with patient-level data from the United States Renal Data System.ResultsAmong 597,968 patients initiating dialysis in the United States in 2005 through 2017, those in cities with detectable lead levels in community water had significantly lower pre-ESKD hemoglobin concentrations and more ESA use per 0.01 mg/L increase in 90th percentile water lead. Findings were similar for the 208,912 patients with data from the first month of ESKD therapy, with lower hemoglobin and higher ESA use per 0.01 mg/L higher lead concentration. These associations were observed at lead levels below the EPA threshold (0.015 mg/L) that mandates regulatory action. We also observed environmental inequities, finding significantly higher water lead levels and slower declines over time among Black versus White patients.ConclusionsThis first nationwide analysis linking EPA water supply records to patient data shows that even low levels of lead that are commonly encountered in community water systems throughout the United States are associated with lower hemoglobin levels and higher ESA use among patients with advanced kidney disease.
