US researchers have found that strategies for conserving water in green buildings can lead to higher levels of bacteria in the plumbing systems, with potentially serious implications for public health.
William Rhoads and colleagues at Virginia Tech conducted a survey of the drinking water quality in different types of green building, from an office to a net-zero energy home. They measured the chlorine levels, temperature and microbial content, including the prevalence of Legionella bacteria, the cause of Legionnaires’ disease. […]
