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.

Leaky pipes ‘could pose health risk’

BBC News 8 June 2015

Leaky pipes may be causing upset stomachs because they allow contaminated water to get into the system, it is being claimed.  Sheffield University’s Prof Joby Boxall issued the warning after studying the risks posed by leaky pipes, especially when pressure drops.

Gold Coast’s stinkiest beach spark calls for animal control officers to step up patrols

Gold Coast Bulletin 3 June 2015

SOUTHERN Palm Beach is officially the Gold Coast’s stinker of a beach.

Confronted with the stench, beach walkers and surfers are questioning the quality of the water in the surrounding surf and lagoon and calling on the council to step up patrols by animal control officers.

Surfrider Foundation spokesman Chris Butler, fearing the lagoon behind the beach was contaminated, complained to the council in October last year.

“We did some quality (water) testing some years ago in the northern end of the lake and the E coli levels were off the Richter (scale) then,” he said.
