In urban Maroua, Cameroon, improved drinking water sources are available to a large majority of the population, yet this water is frequently distributed through informal distribution systems and stored in home containers (canaries), leaving it vulnerable to contamination.
Presently, water contamination issues are of great concern worldwide. Mexico has not escaped this environmental problem, which negatively affects aquifers, water bodies and biodiversity; but most of all, public health.
Do Contaminants Originating from State-of-the-Art Treated Wastewater Impact the Ecological Quality of Surface Waters?
This study highlights the importance of reducing the wastewater-associated impact on surface waters. For aquatic ecosystems in urban areas this would lead to: (i) improvement of the ecological integrity, (ii) reduction of biodiversity loss, and (iii) faster achievement of objectives of legislative requirements, e.g., the European Water Framework Directive.
Shigellosis Outbreak Associated with Contaminated Well Water in a Rural Elementary School: Sichuan Province, China, June 7–16, 2009
This investigation of shigellosis outbreak in an elementary school in Sichuan Province, China, identified the source of infection, mode of transmission and risk factors for illness, and concluded that this shigellosis outbreak was caused by drinking untreated water from a well polluted by Shigella flexneri 2b.
Self-Reported Household Impacts of Large-Scale Chemical Contamination of the Public Water Supply, Charleston, West Virginia, USA
A January 2014 industrial accident contaminated the public water supply of approximately 300,000 homes in and near Charleston, West Virginia (USA) with low levels of a strongly-smelling substance consisting principally of 4-methylcyclohexane methanol (MCHM). We conclude that the spill had major economic impact with substantial numbers of individuals reporting incident-related illnesses and psychological distress. Authorities were successful supplying emergency drinking water, but less so with risk communication.
Source Apportionment and Risk Assessment of Emerging Contaminants: An Approach of Pharmaco-Signature in Water Systems
This paper presents a methodology based on multivariate data analysis for characterizing potential source contributions of emerging contaminants (ECs) detected in 26 river water samples across multi-scape regions during dry and wet seasons.
There is substantial concern that microbial and nutrient pollution by cattle on public lands degrades water quality, threatening human and ecological health.
Soon after the transition was made, residents began complaining about the quality of the water, noting its strange color, taste, and smell. With proceeding investigations, it was found that the Flint river, and therefore the water being supplied to the community, was contaminated with almost unprecedented amounts of lead.
This study explored the combined effects of Assimilable organic carbon (AOC) and free chlorine on bacterial growth in drinking water using flow cytometry (FCM).
Cloud-Enabled Microscopy and Droplet Microfluidic Platform for Specific Detection of Escherichia coli in Water
The ScanDrop platform integrates droplet microfluidics, a portable imaging system, and cloud-based control software and data storage for the rapid and specific capture, detection, and identification of bacteria in drinking water.
