Fire in one part of a community can contaminate the water system used by other residents, as Santa Rosa, California, discovered after the Tubbs Fire.

An increasing number of communities are discovering dangerous contamination in their water systems weeks or months after fires.
We analysed the dust in 32 homes across Sydney, and found significant levels of microplastics. But having hard, non-varnished floors and vacuuming at least weekly might help.
Research estimates that each year some 15,000 deaths, 90,000 hospital admissions and 240,000 years of life lost are directly attributable to alcohol use.
Alcohol is classified by the World Health Organization as a Class 1 carcinogen. Our next federal government must step up with an Alcohol Act and a strategy to reduce harms from this recreational drug.
Research out of the US tested different varieties of beer and wine for the presence of glyphosate – but there’s lots to consider when interpreting the findings.
The amount of alcohol you'd have to drink before glyphosate posed even a negligible risk would harm you well before the glyphosate would.
Individuals using indoor tanning are exposed to two types of UV rays – UVA and UVB – that damage skin and DNA and can lead to cancer, including the deadliest one: melanoma. Young users are most at risk.
Many gyms use free tanning beds to lure in new members who are eager to look and feel their best. But this, argues Sherry Pagoto, runs against the health lifestyle premise these gyms are advocating.
But it’s unclear what that means for cancer risk.
Of the 49 inks tested, only four complied with the European standards. Carcinogens were found in more than one-fifth of the samples, and in 83% of the black inks.
Chemicals that form in cooked food have been linked to cancer – but the full picture is more complicated.
Time to hang up?
The evidence appears contradictory – but there may be a good reason for this.

Coal dust and oil can spread toxic chemicals hundreds of kilometres out to sea. But Australia's monitoring guidelines do not meet the standards used in countries such as the United States.
There are scores of carcinogens. Most aren’t as tasty.
WHO has said that processed meats cause cancer. But there are more, less visible carcinogens to worry about
Fracking in the US has relied on chemicals linked to a range of health problems but the industry claims UK operations would be far safer.
Eleven million cars worldwide could be affected by the scandal.
Volkswagen's cheating allowed its vehicles to pass rigorous emissions testing, giving customers maximum driving performance at the cost of the environment and our health.
No, we’re not swimming around in a soup of cancer-causing chemicals.
Cancer is caused by a combination of genetic and environmental influences – a kind of genetic lottery where the odds are stacked by environmental and lifestyle factors.
While we search for a cure, we are still searching for cause. A volunteer hangs bras during a promotion against breast cancer in Switzerland in 2008.
Major causes have been identified for most common cancers, like liver and lung. But we still haven't identified one for breast cancer.
So serious are the effects of air pollution on human health - the WHO recently categorised it as carcinogenic, responsible for 223,000 deaths a year worldwide - that it is easy to neglect its wider impact…
UC Berkeley’s School of Public Health has investigated 32 different lipsticks and lip glosses for potential health risk through…
