Federal Study Reignites Pollution Concern in Expanding Tar Sands Region

Dr. David Schindler, the scientist who sounded the alarm on tar sands contamination back in 2010, has suddenly found his research backed by an Environment Canada study recently published in the prestigious journal Proceedings of the National Academy of Sciences. The federal study, which confirmed Schindler’s hotly-contested research, has reignited concerns over the pace and scale of development in the Athabasca region, an area now beset with a host of ecological and human health concerns.

EPA And TVA Nix Coal Ash Spill Cleanup Efforts

Four years after a coal processing plant operated by the Tennessee Valley Authority (TVA) accidentally released tons of toxic coal ash into waterways in Kingston, the cleanup has finally come to an end. 

But just because cleanup efforts have ceased, that does not mean that the pollution problem is gone.

In fact, quite the opposite is true.  The U.S. Environmental Protection Agency (EPA) has reached a deal with the TVA to allow the company to stop their cleanup efforts and allow “natural river processes” to dispose of the remaining toxic sludge.

Shrinking Arctic Ice May Cause Mercury Poisoning

Arctic ice cap shrinkage over 32 years

NASA has shown repeatedly that the Actic icecap is melting, and melting faster than climate models predict. This new visualization is stark and should be of obvious concern, simply because of the impact on sea levels. Now there is a potentially new threat. The process of shrinkage may cause a chemical reaction that could poison the Arctic ecosystem with mercury.

The disappearance of old, thick ice in the Arctic means an increase in bromine released into the atmosphere. The new, thinner ice has more salt and this is where the bromine comes from. As it melts it interacts with relatively benign gaseous mercury causing it to solidify and fall in a toxic form to the ground and into ocean water. The old old ice has less salt.

it is currently popular in denier circles to tout the April 2012 ice sheet extension as a sign of slowing of Arctic ice melt. This grasping at straws is not supported by the overall data, which shows Acrtic ice disappearance increasing. The April extent is mainly thinner, new ice that will easily melt, potentially causing the "bromine explosiion" described by NASA. The old, thicker icecap is shrinking more rapidly as time passes, and with it, the benign melting of salt-depleted ice.

Coal Ash Sites Posing Increasing Dangers To Water Supplies, Public Health

The Environmental Integrity Project (EIP) has once again put together a fantastic report regarding water contamination near coal ash disposal sites.

Last year, the EIP released several reports showing that drinking water near coal ash disposal sites in states across America contained dangerous levels of heavy metals and other toxins, including arsenic. In total, last year’s report revealed 53 sites in the United States where coal ash had polluted drinking water supplies.

The new report has identified a total of 116 coal ash sites in America that are leaching deadly toxins into the environment.

The new EIP report resulted from a Freedom of Information Act (FOIA) request to the EPA, which revealed that 49 different coal-fired power plants acknowledged that their own testing showed that groundwater pollution around their disposal sites far exceeded the federally acceptable levels. Among the chemicals reported to exceed federal standards at the coal-fired plants’ disposal sites are:

The State Of The Gulf Two Years After Deepwater Horizon Disaster

Today marks the two-year anniversary of the Deepwater Horizon oil rig explosion that killed 11 rig workers and subsequently caused an oil geyser in the Gulf of Mexico that leaked hundreds of millions of gallons of crude oil into the water. The mainstream press will provide coverage over the next few days, reminding the world that the Gulf Coast is still reeling from the effects of the disaster. But for those of us that call the coast home, we’re reminded of what’s happened everyday.

A lot has happened in the two years since the rig explosion – federal inquiries, scientific testing, corporate investigations. These actions have told us two very important things: The first being that the explosion and oil leak could have easily been prevented had the companies involved not cut corners. The second is that the oil is proving to be much more harmful to the ecosystem in the Gulf of Mexico than most people realize.

The most recent developments in the ongoing saga include rig owner Transocean once again attempted to thwart a thorough investigation into their role in the disaster.
