J. Patrick Coolican: Buffer Bill Passes→

Star Tribune:

“For Dayton, the passage of the bill caps off a week of lobbying that he hopes will galvanize Minnesotans on clean water, which has become one of his signature issues.

“More and more citizens and communities throughout Minnesota are being threatened by water that is unsafe for their drinking, washing and recreation,” he said in his statement last week. “These water quality problems must be addressed by all of us recognizing our shared need for safe and clean water, and our by shared willingness to protect this priceless resource.””

The politics of shoreline buffers is hard. 

Lee Bergquist: Little Plover River Groundwater Study→

Journal Sentinel:

“A long-awaited study that examines how irrigation is affecting the closely watched Little Plover River in central Wisconsin could help prevent the river from running dry again.

The results of the state-funded research also may provide clues on how large-scale groundwater withdrawals are affecting streams, rivers and lakes elsewhere, according to scientists.

Groundwater issues have become increasingly contentious in Wisconsin, especially in the 1.75 million-acre Central Sands region — home to a large potato and vegetable growing industry. The region relies on more than 3,000 high-capacity wells to grow crops.

The Little Plover, a Class 1 trout stream, flows for about 6 miles near Stevens Point before it enters the Wisconsin River. But more than its reputation for fishing, the river is infamously known for stretches that run dry, as they did in 2005 and 2009.”

Good groundwater science was done years ago by Dr. Kraft, who was quoted in this article. However, farmers and civic leaders apparently did not want to hear about how farm irrigation was the main reason for lower river flows. So the science and the predictions are now better and yet some farmers and civic leaders apparently still will not be convinced. When you start with a given pre-set belief or dogma and then search for any argument to rationalize, defend or justify the overexploiting of a pubic resource, then you are corrupt and your actions self-servicing. 

Wisconsin Public Radio's Route 51 broadcast a program discussing the newly released scientific study of the effects of high capacity wells on groundwater and the Little Plover River in the central sands region of Wisconsin. It included a panel discussion with George Kraft, hydrologist with UW Extension in Stevens Point; Tamas Houlihan, executive director of the Wisconsin Potato and Vegetable Growers Association; Scott Krug, Republican Party Assemblyman from the Town of Rome; and Katrina Shankland, Democratic Party Assemblywoman from Stevens Point.

Beth Mole: Antibacterial Soaps Do More Harm Than Good→

Ars Technica:

“Whether you’re coming home from an airport fluttering with international germs, a daycare full of sticky-fingered toddlers, or just a grimy office building, scrubbing your hands with bacteria-busting soap seems like a great idea. But the data that have washed up on the cleansers in recent years suggest that they actually do more harm than good—for you, those around you, and the environment.

Scientists report that common antibacterial compounds found in those soaps, namely triclosan and triclocarban, may increase the risk of infections, alter the gut microbiome, and spur bacteria to become resistant to prescription antibiotics. Meanwhile, proof of the soaps’ benefits is slim.

There are specific circumstances in which those antimicrobials can be useful, civil engineer Patrick McNamara of Marquette University in Milwaukee told Ars. Triclosan, for instance, may be useful to doctors scrubbing for minutes at a time before a surgery or for hospital patients who can’t necessarily scrub with soap but could soak in a chemical bath. Triclosan and triclocarban do kill off bacteria during long washes. But most people only clean their hands for a few seconds. “There’s evidence that there is no improvement with using soaps that have these chemicals relative to washing your hands under warm water for 30 seconds with soaps without these chemicals,” he said.”

Jonathan Kaiman: Groundwater Pollution Crisis in China→

The Guardian:

“Nearly 60% of China’s underground water is polluted, state media has reported, underscoring the severity of the country’s environmental woes.

The country’s land and resources ministry found that among 4,778 testing spots in 203 cities, 44% had “relatively poor” underground water quality; the groundwater in another 15.7% tested as “very poor”.

Water quality improved year-on-year at 647 spots, and worsened in 754 spots, the ministry said.

“According to China’s underground water standards, water of relatively poor quality can only be used for drinking after proper treatment. Water of very poor quality cannot be used as source of drinking water,” said an article in the official newswire Xinhua...”

Sarah DeWeerdt: Bird Deaths From Window Collisions →

Conservation Magazine:

“Collisions with windows are one of the biggest human-related causes of bird deaths in the United States, responsible for up to one billion avian fatalities every year. That’s as much as 9 percent of the country’s entire bird population.

In general, the more windows and the bigger windows a building has, the more dangerous it is for birds. Many green buildings are designed with lots of windows to reduce the need for artificial light and heating. So there can be a tension between saving energy and saving birds.

Glass with etched patterns, mullions, or UV-reflective films can help birds recognize windows as a barrier and avoid flying into them. But scientists have incomplete knowledge of how well these measures work, as well as what aspects of buildings and biology make birds more vulnerable to window strikes in the first place.

Two recent studies conducted on opposite sides of the country fill in some of these details...”

Some alternations of our buildings and bird-friendly designs appear reasonable and responsible. Now if we can reduce mortality due to our domesticated cats...

Thompson and Rogers: Global Warming Threatens Lake Trout→

Thunder Bay News:

“Warming water from climate change is beginning to encroach on the habitat of Northwestern Ontario’s cold water fish. Research conducted at the Experimental Lakes Area shows the region’s temperature has warmed 0.4 C over each of the last five decades. Shorter winters are heating surface water and delaying lake trout spawning.

The runoff from increasing summer rain is causing a tea-like discolouration, affecting the water’s heat distribution and compounding the change. Added together, fish biologist Lee Hrenchuk can see consequences for aquatic ecosystems beginning to show.

“The average size of an adult fish has been decreasing over time and we’re seeing this mostly in the cold water fish species that are really dependent on having good spring periods and good fall periods where they can do a lot of eating,” Hrenchuk said.”
