Is That a Banana in Your Water?
Banana peels are no longer just for composting or comedy shows: New science shows they can pull heavy metal contamination from river water.
Metals such as lead and copper are introduced to waterways from a variety of sources, including agricultural runoff and industrial wastes. Once there, heavy metals can contaminate soils and pose health risks to humans and other species. Lead is known to affect the brain and nervous system... ...

Study: Pharmaceutical chemicals widespread in Minn. streams
Potentially harmful chemicals and pharmaceuticals are widespread in Minnesota streams, state scientists found in a new study.
The study by the Minnesota Pollution Control Agency also shows fish have genetic changes when exposed to the mix of chemicals.... Among the substances scientists most often found are the antibiotic sulfamethoxazole and carbamazepine, a drug used to treat atentionl deficit hyperactivity disorder, agency scientist Mark Ferrey said. They also found the antibiotic trimethoprim and anti-depressant compounds.
Other commonly found chemicals include components of detergent, bisphenol A, which is found in plastics, and contraceptive hormones. ...

Monitoring of oilsands impact inadequate: panel
The province must do a better job of monitoring the impact of oilsands mining on water quality in northeastern Alberta, concludes a scientific panel.
Environment Minister Rob Renner appointed the six-member panel in September 2010 after a University of Alberta study concluded industry was responsible for increased levels of toxins in the Athabasca River, a claim contradicted by government scientists....
It found industry and government monitoring is inadequate in determining the amount of toxins entering the environment....
"It's not just that we have to have more monitoring, but we have to have a more coordinated system for monitoring."
NDP critic Rachel Notley said Renner has known for years that the current system was lacking but did nothing about it.
"The minister can try to rewrite history, but the record shows that while the Tories barged ahead on development, their commitment to environmental protection was in spin only," said Notley. ...

from CBC:
Great Lakes phosphorus levels rising, report warns
A mysterious resurgence of phosphorus in the Great Lakes is endangering the aquatic food chain and human health, says a binational agency that advises Canada and the U.S.
Fifteen years after the last programs to control phosphorus runoff ended, the International Joint Commission urged on Wednesday a renewed effort to get the oxygen-depleting chemical out of the water....
"We don't know where the phosphorous is coming from," Bill Bowerman, chair of the IJC's science advisory board and a wildlife ecologist at South Carolina's Clemson University, said during Wednesday's IJC news conference.
"Some of our monitoring programs that would allow us to understand this either are under threat or have disappeared over the past 15 years."...
The report suggests key factors likely include inadequate municipal wastewater and residential septic systems, agricultural runoff, industrial livestock operations and the impacts of climate change, which causes more frequent and intense rainstorms....
[M]uch of the lake is back to being coated with slimy green algal blooms in the summer, as it was in the 1960s and early '70s.
"They said, 'Well, we have this one fixed.' Well, we don't have this one fixed," she said. ...

Former Bush EPA Official Says Fracking Exemption Went Too Far; Congress Should Revisit
When Benjamin Grumbles was assistant administrator for water at the Environmental Protection Agency in the George W. Bush administration, he oversaw the release of a 2004 EPA report that determined that hydraulic fracturing was safe for drinking water. Then he watched as Congress used those findings to bolster the case for passing a law that prohibited the EPA from regulating fracking under the Safe Drinking Water Act....
Whether it's hydraulic fracturing or any other type of practice that can have an impact on the environment, one single report shouldn't be the basis for a perpetual, never-ending policy decision.
It wasn't meant to be a bill of health saying 'well, this practice is fine. Exempt it in all respects from any regulation.' I'm sure that wasn't the intent of the panel of experts, and EPA never viewed it that way. That's one reason why we were urging Congress to say 'look, if you are going to issue an exemption, ensure that it is not perpetual.' ...

from Montreal Gazette:
Fracking will cause 'irreversible harm'
A geological engineering professor whose specialty is rock mechanics and hydrogeology says hydraulic fracturing to free natural gas from shale rock formations will cause "irreversible harm" lasting thousands of years.
And the gas companies will be long gone, leaving behind costly remediation, Marc Durand said in an interview, suggesting the gas producers should be forced to establish a reserve fund.
"The billions required would be much more than all the profits beckoning now," said the retired Universite du Quebec a Montreal professor.
The circulating gas left behind will threaten the water Quebecers drink and could jeopardize agriculture, he said. The Utica shale field gas deposits between Montreal and Quebec City lie under some of the best farmland in the province....
The rock formations shattered by fracking will be "thousands of times more permeable," allowing the remaining 80 per cent of shale gas and underground water, 10 times more salty than sea water, to continue circulating, bubbling to the surface through the disused gas wells.
Over time, methane could leak into the groundwater and gas leaks could gush, uncontrolled, into the air.

Unregulated pesticide use in Asia destroys ecosystems and threatens resistant 'pest storms'
The unbridled manufacture and use of pesticides in Asia is raising the spectre of "pest storms" devastating the region's rice farms and threatening food security, scientists have warned.
Increased production of cheap pesticides in China and India, lax regulation and inadequate farmer education are destroying ecosystems around paddies, allowing pests to thrive and multiply, they said.
The problem has emerged over the last decade and -- if left unchecked -- pests could lay waste to vast tracts of Asia's rice farms, according to scientists who took part in a workshop in Singapore last week....
"There are big outbreaks of pests or what they are calling in China 'pest storms' as a result of the over-application of pesticides," Lukacs said....
The problem is compounded by indiscriminate application, which has destroyed the ecosystem surrounding the paddies, including the predators such as spiders and dragonflies that would normally keep pest numbers down. ...

If pesticides kill more than just pests, why don't they call it something else, like "poison"?
