Tracking the viral parasites cruising our waterways

(Michigan State University) Humans aren’t the only ones who like to cruise along the waterways, so do viruses. For the first time, a map of fecal viruses traveling our global waterways has been created using modeling methods to aid in assessing water quality worldwide.

GWRC Emerging Contaminants and Pathogens Workshop report

Water Research Australia News 25 June 2015

Stuart Khan from UNSW, currently on sabbatical in Germany, represented WaterRA at a recent GWRC workshop – “Fate and Occurrence of Emerging Contaminants and Pathogens” in Karlsruhe (Germany) in early June. He has prepared this report on the meeting.  Major identified themes included microplastics, antibiotic resistance, risk assessment, microbial indicators,
an emerging contaminants research prioritisation decision making framework; and support for the standardisation of molecular methods for pathogen assessment.

Detecting the undetectable: New chip identifies chemicals in ultratrace amounts

EurekAlert 18 June 2015

A George Washington University professor has designed new technology that can identify traces of chemicals at 10-19 moles, a previously undetectable amount. This minute quantity can be conceptualized as 10 times below a billionth of a billionth of a teaspoon of water.

Water screening: International hunt for unknown molecules

EurekAlert 18 June 2015

The available options for quickly identifying unknown molecules in water have been limited in the past. But the principle of preventative screening is essential when testing surface waters, which frequently serve as drinking water sources. A key goal is “screening to prevent or at least quickly identify potential risks”.

Chemical analyses show that a single water sample can contain thousands different types of molecules. These substances stem from the surrounding environment, but are also introduced by humans in the form of industrial chemicals, pesticides, medications and household chemicals, as well as their respective degradation products. The amounts and composition of these molecules vary from region to region and from country to country, depending on the indigenous vegetation and the drugs, pesticides and chemicals approved for local use.

Don’t drink the water, Paluma residents warned

Townsville Bulletin VICTORIA NUGENT  June 11, 2015

PALUMA residents are being told to boil their drinking water after tests in the town supply found a parasite that can cause bowel infections.
A routine test carried out by Townsville City Council found the water contained giardia, a parasite causing a form of gastroenteritis.
Flyers were dropped in letterboxes yesterday warning residents of the dangers, with signs to be installed on public taps and at the entrance to town. The scare comes as money was set aside in the council budget to design and construct a new water treatment facility for the township.
