Natural Organic Matter, Orthophosphate, pH, and Growth Phase Can Limit Copper Antimicrobial Efficacy for Legionella in Drinking Water
(2021-02-02)
Copper (Cu) is a promising antimicrobial for premise plumbing, where ions can be dosed directly via copper silver ionization or released naturally via corrosion of Cu pipes, but Cu sometimes inhibits and other times ...
Critical Review: Propensity of Premise Plumbing Pipe Materials to Enhance or Diminish Growth of Legionella and Other Opportunistic Pathogens
(MDPI, 2020-11-17)
Growth of <i>Legionella pneumophila</i> and other opportunistic pathogens (OPs) in drinking water premise plumbing poses an increasing public health concern. Premise plumbing is constructed of a variety of materials, ...
Relationship between Organic Carbon and Opportunistic Pathogens in Simulated Glass Water Heaters
(MDPI, 2015-06-09)
Controlling organic carbon levels in municipal water has been hypothesized to limit downstream growth of bacteria and opportunistic pathogens in premise plumbing (OPPPs). Here, the relationships between influent organic ...
Interactive Effects of Copper Pipe, Stagnation, Corrosion Control, and Disinfectant Residual Influenced Reduction of Legionella pneumophila during Simulations of the Flint Water Crisis
(MDPI, 2020-09-04)
Flint, MI experienced two outbreaks of Legionnaires’ Disease (LD) during the summers of 2014 and 2015, coinciding with use of Flint River as a drinking water source without corrosion control. Using simulated distribution ...
Chlorine Disinfection of Legionella spp., L. pneumophila, and Acanthamoeba under Warm Water Premise Plumbing Conditions
(MDPI, 2020-09-22)
Premise plumbing conditions can contribute to low chlorine or chloramine disinfectant residuals and reactions that encourage opportunistic pathogen growth and create risk of Legionnaires’ Disease outbreaks. This ...
Effect of heat shock on hot water plumbing microbiota and Legionella pneumophila control
(2018-02-09)
Background
Heat shock is a potential control strategy for Legionella pneumophila in hot water plumbing systems. However, it is not consistently effective, with little understanding of its influence on the broader plumbing ...
Water Safety in California Public Schools Following Implementation of School Drinking Water Policies
(Centers for Disease Control and Prevention, 2020-12-01)
Introduction: Recent legislation requires public and charter schools in California to test drinking water for lead. Our objective was to describe 1)results from this testing program in the context of other available water ...
Challenges of Detecting Lead in Drinking Water Using at-Home Test Kits
(2021-02-02)
Lead in drinking water remains a significant human health risk. At-home lead in water test kits could provide consumers with a convenient and affordable option to evaluate this risk, but their accuracy and reliability is ...
Sustainable Water through Innovation in Membranes & Materials (SWIMM)
(Virginia Tech, 2017-05-15)
Water scarcity is mainly caused by overwhelming human consumption and contamination, from production of water-thirsty meats and vegetables, biofuel crop production, industrial uses, and rapid urbanization. The scale of ...
Impact of water heater temperature setting and water use frequency on the building plumbing microbiome
(2017-06)
Hot water plumbing is an important conduit of microbes into the indoor environment and can increase risk of opportunistic pathogens (for example, Legionella pneumophila). We examined the combined effects of water heater ...
