Legionella pneumophila was quantified during the COVID-19 pandemic in 26 buildings three countries to identify factors that influenced positivity.
Antimicrobial silver materials for drinking water disinfection have become increasingly popular in building-wide systems (e.g., copper-silver ionization) and point-of-use applications containing plumbing fixtures) to combat the microbial growth of associated pathogens that can cause infections immunocompromised (DWPIs). However, evaluations various silver-containing treatments suggest their efficacy is often temporary or incomplete. A potential explanation these observations insufficient...
Low-flow showerheads offer consumers economic and water-saving benefits, yet their use may inadvertently affect the microbial content of produced water water-associated aerosols. This study aimed to compare abundance composition bacteria in shower associated respirable aerosols by various low flow rate (1, 1.5, 1.8 gpm) showerheads. Our findings indicate that lowest-flow showerhead produces with lower total opportunistic bacterial pathogen densities compared higher counterparts. However,...
The incidence of waterborne disease outbreaks in the United States attributed to drinking water-associated pathogens that can cause infections immunocompromised DWPIs (e.g.,
Respiratory infections from drinking water-associated pathogens that can cause in the immunocompromised (DWPIs) are increasing, yet knowledge of DWPI aerosolization and if dynamics DWPI-specific is lacking. Although there several mitigation strategies, use antimicrobial showerheads one easiest most economical. There many manufacturers designs claim to remove microorganisms shower water, all fail assess efficacy realistic conditions. In this study, a custom-built laboratory housing...
Abstract In spring 2020, reduced water demand was an unintended consequence of COVID-19 pandemic-related building closures. Concerns arose that contaminants associated with stagnation, such as Legionella pneumophila , could become prevalent. To investigate this potential public health risk, samples from 26 reduced-occupancy buildings across 11 cities in the United States, Canada, and Switzerland were analyzed for L. using liquid culture (Legiolert, n=258) DNA-based methods (qPCR/ddPCR,...
Reinforced concrete (RC) is the most widely used construction material in world, but its susceptibility to cracking ultimately shortens structure’s operational lifetime. When cracked, water can enter RC and undergo cycles of freezing thawing, causing further damage corrosion reinforcement. While many conventional crack remediation strategies are effective short term, they high maintenance be environmentally hazardous due emission volatile organic carbons or chemical runoff. Microorganisms...
