Water contamination events in UK drinking-water supply systems.
Water supply companies in the UK have a duty under prime UK legislation to notify the Drinking Water Inspectorate of events affecting or potentially affecting the quality of drinking-water supplies. Under the same legislation, the Inspectorate has a duty to investigate each event. After assessing all of the information available, including companies' reports, the Inspectorate advises on the way...
متن کاملHazards of heavy metal contamination.
The main threats to human health from heavy metals are associated with exposure to lead, cadmium, mercury and arsenic. These metals have been extensively studied and their effects on human health regularly reviewed by international bodies such as the WHO. Heavy metals have been used by humans for thousands of years. Although several adverse health effects of heavy metals have been known for a l...
متن کاملModelling Water Quality for Water Distribution Systems
Maintaining water quality in distribution systems has become a prominent issue in the study of water networks. This thesis concentrates on disinfectant and particle counts as two important indicators of water quality. The models discussed in this work are based on data collected by the author. The experimental set-up and procedure are described and observations of particle counts, particle coun...
متن کاملVirus contamination from operation and maintenance events in small drinking water distribution systems.
We tested the association of common events in drinking water distribution systems with contamination of household tap water with human enteric viruses. Viruses were enumerated by qPCR in the tap water of 14 municipal systems that use non-disinfected groundwater. Ultraviolet disinfection was installed at all active wellheads to reduce virus contributions from groundwater to the distribution syst...
متن کاملAssessing Inhalation Exposures Associated with Contamination Events in Water Distribution Systems
When a water distribution system (WDS) is contaminated, short-term inhalation exposures to airborne contaminants could occur as the result of domestic water use. The most important domestic sources of such exposures are likely to be showering and the use of aerosol-producing humidifiers, i.e., ultrasonic and impeller (cool-mist) units. A framework is presented for assessing the potential effect...
