EPA issues order to protect Yakama Nation drinking water

Retrieved from: Scientific American

“The U.S. Environmental Protection Agency, Region 10, has ordered two gas stations to close their underground injection wells to protect drinking water on the Yakama Indian Reservation in Washington.

Da Stor at Lillie’s Corner gas station, in Wapato, operates two underground injection wells. Cougar Den gas station in White Swan operates one underground injection well.

The injection wells dispose of untreated fluids collected through open drains on the stations’ fueling pads. The wells may contain contaminants such as benzene, toluene, ethylbenzene, xylenes, cadmium, chromium, and lead that could endanger underground drinking water sources.

Groundwater is the primary source of drinking water for the communities of Wapato and White Swan.”

Canada’s method of water treatment a ‘national embarrassment’

Retrieved from: Global news

“To Mark Mattson, Canada’s  old   fashioned method of water   treatment is a national embarrassment.

“We’re probably one of the most backwards countries in terms of treating our water,” says Mattson, who runs the Lake Ontario Waterkeepers, an organization that advocates for clean, safe water.

Until recently, municipalities were only required to use primary treatment, meaning wastewater plants would clean solid waste – or “floatables” – from the water. Primary treatment doesn’t include liquids, such as spoiled milk, or cleaning products and even the old medications that get poured down our drains.

“We might have removed at best about 70 per cent of the suspended solids here,” says North Vancouver Mayor, Darrell Mussatt at the Lions Gate Wastewater Treatment plant.

Cities such as Vancouver, on the Pacific Ocean, have been banking on the old notion that ‘dilution is the solution to the pollution’ for years – that water dilutes and assimilates waste.”

Gap Dumping Toxic Wastewater

“Gap, Brooks Brothers and other fashion brands are dumping toxic wastewater in Indonesia waterways, Greenpeace says.

In its latest report, Toxic Threads: Polluting Paradise, Greenpeace investigates the PT Gistex factory, located near Bandung in West Java, with 60 percent of production located in the Citarum River watershed. The facility does polyester weaving and wet processing for several fashion brands, Greenpeace says. The nonprofit collected samples of wastewater discharged from the PT Gistex facility and found toxic chemicals — including nonylphenol (NP), nonylphenol ethoxylate (NPE) and tributyl phosphate (TBP) — being pumped in the Citarum.

NPs and NPEs are highly toxic to aquatic organisms, the EPA says. Once released into the water system, NPEs degrade to NP, which is bioaccumulative and can act as a hormone disruptor, according to the agency. TBP is also toxic to aquatic life.

Brooks Brothers has acknowledged a business relationship with parts of PT Gistex Group, the report says. Greenpeace says is has urged the company to sign on to its Detox Fashion campaign and eliminate hazardous chemicals from its supply chains and products.”

Can Jakarta ever root out the problems that cause so much destruction after every monsoon season?

Photo retrieved from: www.inquirer.net

“Jakarta, Indonesia, is one of Asia’s most flood-prone cities. Every year hundreds of thousands of citizens living in the capital of Southeast Asia’s largest economy brace for the loss of business, shelter and livelihoods.

Each year, as the rainy season approaches, the authorities insist they are ready to counter the tides of brown murky water, trash, and even animals, surging downstream. But the annual city-wide submergence continues.

This year’s sustained downpour threatens to prompt the kind of flooding not seen since 2007 when 350,000 people were evacuated from water-logged areas and dozens were killed. Already, at least 100,000 people have been affected. Army personnel have been deployed to some of the city’s poorest parts to clean up – a process likely to take weeks, if not months.

Asia’s monsoon season prompts annual debate about the state of infrastructure and the fundamental mismanagement of vital systems meant to keep some of the world’s biggest cities moving. With a population of 10 million, Jakarta’s latest battle to stem the tide highlights a deeper political and social problem: The government’s inability to remove and rehabilitate low-lying slum areas; an unwillingness on part of thousands of poor people to leave dangerous areas despite the risk to themselves and their families; and the overwhelming problem of waste and dumping, often cited as the biggest hindrance to keeping Indonesia “flood-free”.

Indonesia faces a formidable challenge: The country’s economy is growing at breakneck speed, its population is rising and the pressures on its decaying systems are mounting. The World Bank has stepped in to help save what it describes as a “sinking city”, due to rising sea levels, trash and annual rain. To dig the city out of its mess, the World Bank has invested $200 million to dredge parts of Jakarta.”

Nuclear Dump in Washington Leaking Radioactive Waste

Photo retrieved from: www.commondreams.org

“On Friday, the U.S. Department of Energy said liquid levels are decreasing in one of 177 underground tanks at the site. Monitoring wells near the tank have not detected higher radiation levels, but Inslee said the leak could be in the range of 150 gallons to 300 gallons over the course of a year and poses a potential long-term threat to groundwater and rivers.

The Northwest News Network, in an interview with Tom Carpenter, head of the Seattle-based watchdog group Hanford Challenge, found that Friday’s news highlights the fact that problems have been endemic to the site for years and there’s not even a place to transfer the contained waste or a place to return any that may be recovered from spills or leaks.

“If you have another leak, what do you do?,” ask Carpenter.  “You don’t have any strategy for that. And the Hanford Advisory Board and the state of Washington and Hanford Challenge and others have been calling upon the Department of Energy to build new tanks. That call has been met with silence.”

And the Chicago Tribune adds:

Though more than a third of the 149 old single-shell tanks at the site are suspected to have leaked up to 1 million gallons of nuclear waste over the years, this is the first confirmed leak since federal authorities completed a so-called stabilization program in 2005 that was supposed to have removed most liquids from the vulnerable single-shell tanks.”

Traces Of Anxiety Drugs May Make Fish Act Funny

Photo retrieved from: www.npr.org

“The water is likely to be considerably cleaner upstream and downstream from the sewage plant where the Swedish perch were captured.

Adding more uncertainty in this case: Benzodiazepines have been used for decades in Sweden, so they have no doubt been in this aquatic ecosystem for many years.

“These fish may have adapted to that,” Schlenk says.

Scientists now realize that low levels of pharmaceuticals have spread through the environment. For instance, Schlenk has found a Valium-like drug in the hornyhead turbot, a fish that lives on the seafloor off the California coast. Other lab studies have shown that human drugs can affect the behavior of striped bass and other species.

These drug traces don’t pose an obvious threat to people, who might drink water from streams or eat the fish that live in them.

“The presence of pharmaceuticals in surface waters — or even the residues that accumulate in edible in fish and shellfish — are much lower than what you might need to gain a therapeutic dose,” says Bryan Brooks of Baylor University in Waco, Texas.

But, he cautions, that isn’t necessarily the case in the developing world.”

“Some of the observations in India, for example, downstream of manufacturing facilities, are among the highest concentrations of pharmaceuticals reported in the environment,” he says. “So the developing world really deserves some additional attention.”

Queensland Floods Heighten Crisis Around Toxic Mine Water

Photo retrieved from: www.abc.net.au

“According to the Resources Council, those releases will probably negate the most recent rainfall, but won’t reduce the legacy water. Going into this summer’s wet season, it was estimated there was the equivalent of half Sydney Harbour’s worth of so-called legacy water, which has accumulated in mine pits, especially in the northern Bowen Basin region, since 2008.

There’s also an uncontrolled release of water from one of the most toxic disused mines in Queensland—Mount Morgan. The former gold mine, 40km south of Rockhampton, is situated on the Dee River. It closed in 1981 and is being managed by the Queensland government. Michael McCabe, the coordinator of the Capricorn Conservation Council says it contains highly acidic water.

‘Well, some have compared the acidity of that water to close to battery acid,’ Mr McCabe said.

About 700 mm of rain has fallen over the Mount Morgan mine site since last Wednesday. As a result, the water level in the mine’s open cut pit has been overflowing since Saturday morning, at a rate of about 60 megalitres a day. The state government says strong natural flows in the Dee River have achieved significant dilution of untreated water entering the river, minimising potential downstream impacts.”

Punjab ranks high in water pollution by industries

Photo retrieved from: www.wikipedia.org

“The SAD-BJP government’s claims about attracting over a lakh crore rupees of investment in Punjab have been proven hollow, evidently by their own admission. Not just are the bigger industries moving out, but Punjab is among the worst performing states in the country when it comes to checking water pollution. The state is among the worst defaulters in the country with at least seven grossly polluting industrial units dumping their toxic waste directly in the rivers and lakes.

The latest environment report of the state,Environment Statistics, has expressed concern over the present industrial scenario having a depressing effect on the economy. The report, released this week, clearly states that not just “the number of large industries in state is going down, but the state economy is based on small scale industries, mostly food processing industries.”

Of the 20 grossly polluting industries not even half, nine units, comply with norms regarding water pollution. The others are discharging toxic waste in the state’s lifeline – its rivers and lakes. Punjab ranks seventh on the list of defaulting states with most other states –Bihar, Tamil Nadu, Andhra Pradesh, Assam and Jharkhand — managing to have not a single such polluting unit. The industrially-strong Gujarat has reported one such unit. In Punjab, a few industrial units in Jalandhar and Ropar are dumping toxic waste into the river.”

Chinese Mayor Apologizes for Drinking Water Contamination

Photo retrieved from: www.scmp.com

“The mayor of the Chinese city of Changzhi apologized for a delay in reporting a poisonous leak from a chemical plant that caused the cutoff of water to 1 million people, the state Xinhua News Agency said.

The environmental authority in China’s northern Shanxi province didn’t receive a report about the pollution from the city until five days after the Dec. 31 incident when it should have been reported within two hours, the official news agency said, citing a news conference with the mayor.

About 9 metric tons of aniline, a colorless and poisonous liquid chemical, spilled from a plant owned by Shanxi Tianji Coal Chemical Industry Group, which also makes fertilizer, disrupting the drinking water supply in Handan city downstream in Hebei province, according to Xinhua. The leak was due to a loose drainage valve, Xinhua said.

Thirty more tons of aniline, which can be used to make pesticides, have been found in a nearby disused reservoir, it said, citing a local emergency response agency. The local environmental bureau is cleaning up the contamination in its reservoir, where water won’t be used until tests prove it safe.”

Loophole Lets Toxic Oil Water Flow Over Indian Land

Wind River Reservation. Retrieved from: www.blog.lib.umn.edu

“These operations have the federal government’s permission to dump wastewater on the land — so much that it creates streams that flow into natural creeks and rivers. And this water contains toxic chemicals, including known carcinogens and radioactive material, according to documents obtained by NPR through Freedom of Information Act requests.

The fumes hitting Martel’s nose are hydrogen sulfide, which can be deadly. So Martel makes sure the wind is at his back before walking over to a pit the size of several tennis courts. Pipes are emptying dirty brown water that came up from oil wells into the pit, which is completely covered in goopy black oil.

The oil is supposed to float to the surface, and then a truck will vacuum it up. Any solid stuff should fall on the bottom of the pit, before the water rushes out and forms a stream. But there are still chemicals in the water — some from the earth, some from the oil, and some the companies add to make the oil flow faster.

About a half-mile from the pit, Martel stops the car on a bridge over that stream of murky gray water. A shiny film covers the water in some places.”
