Cyto- and genotoxic profile of groundwater used as drinking water supply before and after disinfection
The assessment of the toxicological properties of raw groundwater may be useful to predict the type and quality of tap water. Contaminants in groundwater are known to be able to affect the disinfection process, resulting in the formation of substances that are cytotoxic and/or genotoxic. Though the European directive (98/83/EC, which establishes maximum levels for contaminants in raw water ...

Waterborne disease outbreak detection: an integrated approach using health administrative databases
Hundreds of waterborne disease outbreaks (WBDO) of acute gastroenteritis (AGI) due to contaminated tap water are reported in developed countries each year. Such outbreaks are probably under-detected. The aim of our study was to develop an integrated approach to detect and study clusters of AGI in geographical areas with homogeneous exposure to drinking water. Data for the number of AGI cases ...

Nosocomial pseudo-outbreak of
Mycobacterium gordonae associated with a hospital's water supply contamination: a case series of 135 patientsNontuberculous mycobacteria (NTM) are opportunistic pathogens found in natural and human-engineered waters. In 2009, a relative increase in the isolation of Mycobacterium gordonae from pulmonary samples originating from General Hospital Zabok was noted by the National Mycobacteria Reference Laboratory. An epidemiological survey revealed a contamination of the cold tap water with M. gordonae and ...

Perfluorinated compounds contamination in tap water and bottled water in Bangkok, Thailand
Perfluorinated compounds (PFCs) such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have been detected in the environment, in biota and in humans. The exposure pathways of these chemicals to humans are unclear. Tap water and bottled water are two possible pathways of PFCs occurrence in human blood. The major objectives of the study were to identify the occurrences of PFCs ...

The bacteriological quality of drinking water in Haldwani Block of Nainital District, Uttarakhand, India
A cross-sectional study was conducted to assess the bacteriological quality of water in Haldwani block, Nainital District, India. Stratified random sampling was used to categorize water sources and consumer points. In total, 108 samples were collected: 15 from the Gola river, 51 from water taps, 24 from water treatment plants and 18 from tube wells. Samples were tested for coliforms by the most ...

Study Quantifies Drinking Water Nitrate’s Role in U.S. Cancer Cases
Negative health outcomes from nitrate in drinking water hit farming communities particularly hard A new Environmental Working Group (EWG) study, published inEnvironmental Research, has estimated that nitrate contamination of drinking water will cause thousands of cancer cases annually in the United States. The cancers are also expected to run up $1.5 billion in medical bills each year, with ...

Virus 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 ...

Secondary removal of chlorophenolic contaminants in water
In this study, several factors important for the design of a water supply treatment system for the removal of trace amounts of organic contaminants by microorganisms in a fixed-film were assessed. This entailed evaluating the effect of seeding with adapted microorganisms on the acclimation time, determining what depth of support material was required for removal of contaminants and observing the ...

This polluted lake shows why we are all stakeholders when it comes to clean water
When environmental protection gets short shrift, the price we pay can be staggering. When I visited Onondaga Lake in 1999 as part of research I did as a student at Cornell, there was no evidence the lake was once home to vibrant waterfront resorts. Yet, in the late 1800s and early 1900s, Onondaga was considered “the Coney Island of Central New York,” with bustling amusement parks, ...

Water pressure too low: Possible causes and remedy
In the physical sense, water pressure is the hydrostatic pressure in water. It increases with increasing water depth and is referred to as the water column and measured in meters of water column, mH2O or mWS for short. A meter of water column is about 0.10 bar. In everyday life, water pressure refers to the the force applied per unit area with which the fresh water - alternatively also called tap ...
