Sharon Lerner: The Tragic Story of C8 (perfluorooctanoic acid or PFOA)→

The Intercept:

“A man-made compound that didn’t exist a century ago, C8 is in the blood of 99.7 percent of Americans, according to a 2007 analysis of data from the Centers for Disease Control, as well as in newborn human babies, breast milk, and umbilical cord blood. A growing group of scientists have been tracking the chemical’s spread through the environment, documenting its presence in a wide range of wildlife, including Loggerhead sea turtles, bottlenose dolphins, harbor seals, polar bears, caribou, walruses, bald eagles, lions, tigers, and arctic birds. Although DuPont no longer uses C8, fully removing the chemical from all the bodies of water and bloodstreams it pollutes is now impossible. And, because it is so chemically stable — in fact, as far as scientists can determine, it never breaks down — C8 is expected to remain on the planet well after humans are gone from it.

Eight companies are responsible for C8 contamination in the U.S. (In addition to DuPont, the leader by far in terms of both use and emissions, seven others had a role, including 3M, which produced C8 and sold it to DuPont for years.) If these polluters were ever forced to clean up the chemical, which has been detected by the EPA 716 times across water systems in 29 states, and in some areas may be present at dangerous levels, the costs could be astronomical — and C8 cases could enter the storied realm of tobacco litigation, forever changing how the public thinks about these products and how a powerful industry does business.”

Elizabeth Grossman: Summarizing Drugs in our Water→

Ensia:

“There’s no way around it, the headlines are disturbing. And they come, not from tabloids or click-bait blogs, but from papers published in scientific journals. They describe fish and birds responding with altered behavior and reproductive systems to antidepressants, diabetes medication, and other psychoactive or hormonally active drugs at concentrations found in the environment. They report on opiods, amphetamines and other pharmaceuticals found in treated drinking water; antibiotics in groundwater capable of altering naturally occurring bacterial communities; and over-the-counter and prescription drugs found in water leaching from municipal landfills. And these are just some of many recent studies examining the countless pharmaceuticals that are now being found just about everywhere scientists have looked for them in the environment.”

Christopher Hawthorne: City Freeways Are No Longer the Solution→

LA Times:

“The relationship between Southern Californians and our freeways is broken. Freeways still enable mobility — at certain times of the day. At many other times, they actively seem to frustrate it. They don’t stitch together the region, if they ever did, as much as divide it. The idea that they help us make sense of Los Angeles — that they operate as existential way-finding devices — now seems quaint, at best...

Increasingly the fundamental task Los Angeles faces is one of re-urbanization — of infill development, of reanimating or repairing the public realm. At the heart of that task is an understanding that the most successful kinds of spaces in the city are the ones where a broad range of activities has a chance to play out.

In this emerging Los Angeles, the freeway is an outlier, a hulking support system for an aging, if not outdated, set of beliefs. The freeways were built to allow the region to stretch outward; the movement that counts now is in the opposite direction, as the city doubles back on itself, looking to develop more densely areas where it built lightly before.”

Mass transit was our past and it is our productive future.

Linda Poon: Putting Citizens at the Center of Urban Design→

CityLab:

“Creating a lively public space isn’t as easy as building it and waiting for the crowds to come. There’s a lot that city planners have to consider: How much space is available? What’s the target demographic? How can a public space be made energy efficient?

A group of researchers at MIT thinks that there’s an important piece of the puzzle that’s too often overlooked: the human experience. Studying how people interact with cars, buildings, and sidewalks within an urban space says a lot about its quality, says Elizabeth Christoforetti, an urban and architectural designer at MIT Media Lab.

With a $35,000 grant from the Knight Prototype Fund, she and her team are working on a project called Placelet, which will track how pedestrians move through a particular space. They’re developing a network of sensors that will track the scale and speed of pedestrians, as well as vehicles, over long periods of time. The sensors, which they are currently testing in downtown Boston, will also track the “sensory experience” by recording the noise level and air quality of that space.”

NASA: Less Algae, Not Clear Water, Keeps A Lake Blue→

“Lake Tahoe’s iconic blueness is more strongly related to the lake’s algal concentration than to its clarity, according to research in “Tahoe: State of the Lake Report 2015,” released today by the Tahoe Environmental Research Center (TERC) of the University of California, Davis. The lower the algal concentration, the bluer the lake.

Data from a research buoy in the lake, owned and operated by NASA’s Jet Propulsion Laboratory, Pasadena, California, enabled Shohei Watanabe, a postdoctoral researcher at TERC, to create a Blueness Index that quantified Lake Tahoe’s color for the first time.

The assumption that lake clarity is tied to blueness has driven advocacy and management efforts in the Lake Tahoe Basin for decades. But Watanabe’s research showed that at times of the year when the lake’s clarity increases, its blueness decreases, and vice versa.

Watanabe combined the blueness measurements with data on clarity. Clarity is measured by observing the depth at which a dinner-plate-sized white disk remains visible when lowered into the water. He was surprised to find that blueness and clarity did not correspond. In fact, they varied in opposite directions.

This is due to seasonal interplay among sediment, algae and nutrients in the lake. Clarity is controlled by sediment. Blueness is controlled by algal concentration, which in turn is controlled by the level of nutrients available to the algae.”

We’ve dropped anchor near the shore of Jute Lake, and waves whip the side of the boat vigorously in the high wind. It’s a beautiful day, utterly devoid of cloud cover, but the wind is sharp and swift over the water, forcing us to don our sweatshirts and windbreakers to stave off the chill. Michaela and I, both UW-Madison undergraduates, wait in the boat while Ellen Albright, a student at Minnesota’s Macalester College, wades along the shoreline, dragging a tape-measure behind her.”

Alana Semuels: Contaminated Drinking Water →

Atlantic:

“None of the samples Walters sent were safe to drink. Some had lead content of 200 parts per billion. Over 30 samples, the average lead content was 2,000 parts per billion, which meant that no matter how long Walters let her taps run, it still would have been toxic. This could easily have been causing the health problems that Walters and her children were experiencing.

“Lead is the best known neurotoxin, it adversely impacts every system in the human body,” Edwards told me. “Certainly it could have caused children’s lead poisoning.”

The city says it does not know why so much lead was found in Walters’ pipes, but Edwards has a theory: Many cities have lead pipes, and when water sits in those pipes, the lead can leech into the water. So cities usually add corrosion-control chemicals, such as phosphates, to keep the lead out of the water. But because Flint didn’t take such precautions when they began pumping their own water, “the public health protection was gone,” Edwards says.”

See the other 'lead' tagged articles on this site. The best crime prevention may be lead reduction programs. A causal link not understood by many city government officials.

“A recent study found three dozen bodies of water with chloride levels that exceed state standards. Too much salt can harm fish and encourage invasive plants.

The MPCA’s Brian Livingston, who supervises the metro watershed district, said there are ways to reduce salt use without compromising winter road safety. Such methods, he said, include “wetting the salt so it doesn’t bounce off the highways and actually gets applied directly onto the surface, and measuring more accurately the amount of salt that’s being applied, and not over-applying it.””

Hal Schramm: Why Great Lakes Smallmouth Bass are Big→

Outdoor Life

“The Beaver archipelago is a group of islands in the middle of northern Lake Michigan. A comparison of fishery metrics taken from 1969 through 1984 and from 2005 through 2008 reveal drastic changes.

At Beaver Island 40 years ago, brown bullheads made up 60 percent and smallmouth and rock bass 14 percent of the total number of fish obtained in routine samples. A total of 14 other species made up the remaining 12 percent. From 2005 to 2008, smallmouth samplings grew to a whopping 93 percent of the total.

Despite their dramatic rise to dominance in the Beaver Island fish mix, neither the abundance nor the mortality of bronzebacks changed significantly from the historic periods. But smallmouth bass size structure indices (the proportions of fish greater than 12, 14, and 17 inches), growth rate, and body condition (plumpness) were significantly greater in the more recent period than they were 40 years ago.”

“Mamie Parker, a former assistant director of fisheries and habitat conservation at the U.S. Fish and Wildlife Service, was the first African-American to head a regional office for that agency. But when she started out in the field, she says, she “did not see anyone that looked like me doing this type of work.”

When she was in ninth grade, Parker says, “I heard the song by Marvin Gaye, ‘Mercy, mercy me. Things are not like they used to be.’ He talked about the pollution in the air, and the wind that was blowing poison and radiation and all of that.” She decided she wanted to do something about it.”

Michael Swearingen: BP Settlement for Minnesota's Loons→

MPR:

“Minnesota loons could benefit from an $18.7 billion legal settlement over the massive 2010 Gulf of Mexico oil spill, a Department of Natural Resources official said Wednesday.

Minnesota could receive up to $25 million over the next 15 years from the settlement between oil company BP and the federal government, Carrol Henderson, the department’s nongame wildlife supervisor, told MPR News.

Scientists have conducted a large amount of research documenting the effects of the April 2010 oil spill on wildlife, and the settlement might not have been reached without that research, Henderson said.

”Loons and pelicans were actually in the gulf in April when the oil spill first occurred,” he said. “My recollection is that there was just shy of 200 loons that were found dead in the oil.””

Lisa Palmer: Genetically Modified Mosquitos→

Yale Environment 360:

“When people think of genetically modified organisms, food crops like GM corn and soybeans usually come to mind. But engineering more complex living things is now possible, and the controversy surrounding genetic modification has now spread to the lowly mosquito, which is being genetically engineered to control mosquito-borne illnesses.

A U.K.-based company, Oxitec, has altered two genes in the Aedes aegypti mosquito so that when modified males breed with wild females, the offspring inherit a lethal gene and die in the larval stage. The state agency that controls mosquitos in the Florida Keys is awaiting approval from the federal government of a trial release of Oxitec’s genetically modified mosquitos to prevent a recurrence of a dengue fever outbreak. But some people in the Keys and elsewhere are up in arms, with more than 155,000 signing a petition opposing the trial of genetically engineered mosquitoes in a small area of 400 households next to Key West.”

Kaye LaFond: Lake Baikal Pollution→

Circle of Blue:

“Nutrient pollution from outdated sewage-treatment plants degrades water quality in the world’s deepest, oldest lake.

Siberia’s Lake Baikal is the world’s largest lake by volume, containing nearly 20 percent of the planet’s fresh surface water. The ancient lake harbors an astounding array of biodiversity and is so treasured in Russia that it has its own anthem.

Excessive nutrients, most likely from outdated sewage-treatment facilities in coastal cities, are now spoiling the waters of Baikal with waves of an alga called Spirogyra. During the fall of 2013, researchers found blooms of the algae along the northwest coast of the lake, near the town of Severobaikalsk and the estuary of the Tyya River.”

John Seewer: States Agree to Reduce Phosphorus Runoff to Lake Erie→

Associated Press:

“ Ohio and Michigan have agreed to sharply reduce phosphorus runoff blamed for a rash of harmful algae blooms on Lake Erie that have contaminated drinking water supplies and contributed to oxygen-deprived dead zones where fish can’t survive.

The two states along with Ontario, Canada, said Friday that they will work to cut the amount of phosphorus flowing into western Lake Erie by 40 percent within the next 10 years.

It’s a significant move to combat the algae blooms that have taken hold in the western third of the lake over the last decade and colored some of its waters a shade of green that’s drawn comparisons to pea soup and the Incredible Hulk.

Researchers have linked the toxic algae to phosphorus from farm fertilizers, livestock manure and sewage treatment plants that flows into rivers and streams draining into the lake.”

The goal will need to be followed up with effective actions. Lake Erie is a great resource, and it is great to see politicians making commitments to clean up this lake.

Doug Smith: Governor Dayton signs bill to mandate buffers→

Star Tribune:

“The governor said the ­buffer bill will be one of his most important legacies.

“I think we’ll see in the next couple of years a very significant expansion in the number and quality of buffers to make our water cleaner and increase wildlife habitat,” he said. “Given the predictions that were made at the beginning of the session, that nothing would happen, I think this is a very significant accomplishment.”
...
Said Dayton: “We put the deterioration of Minnesota’s water quality and wildlife habitat on the front burner. It directs attention to the fact that we need to be doing a lot more. “It’s a very important first step, but it’s not the last step.””

Well done Governor Dayton! You tackled a difficult issue, informed people along the way, found reasonable compromises to move it forward, and acknowledged that more work still needs to be done. Good governance and great progress on an important environmental issue. 

Eric Jaffe: Tear Down the Expressway in Toronto→

CityLab:

“Writing at the blog Architect This City about the Gardiner debate, transport planner Darren Davis of Auckland, New Zealand, gives a simple four-part explanation for what happens to traffic when a major roadway gets removed or altered. Some people change their routes. Some shift their travel times to hit the road earlier or later. Some switch from cars onto public transit or another mode. And some—typically the case for non-work travel—just don’t make the trip at all.

At the end of his recent op-ed favoring a teardown, Globe and Mail architecture critic Alex Bozikovic asked: “But are we building a city? Or a highway?” Toronto won’t live or die based on the Gardiner decision, but it will be answering that critical question.”

One should tear it down for the opportunity for citizens to be close to the waterfront. 

John Myers: Study finds widespread drug pollution in Minnesota lakes→

Pioneer Press:

“A chemical associated only with X-ray technology is showing up in Lake Kabetogama in Voyageurs National Park and other northern lakes, one of many industrial compounds showing up in samples taken from Minnesota waterways.

The Minnesota Pollution Control Agency on Tuesday released the results of its latest survey of 11 lakes and four rivers tested for 125 different chemicals, many of which are suspected of being harmful to the environment and, possibly, to humans.

Several of the compounds are considered so-called endocrine-disrupting chemicals that, in other studies, were shown to cause male fish to develop female characteristics and spurred other disruptions in ecosystems.

The survey shows that even remote Minnesota waters are contaminated by a variety of pharmaceuticals, ingredients of personal care and hygiene products as well as endocrine-disrupting compounds — everything from antibiotics, nicotine, caffeine and antidepressants to medications that regulate diabetes, cholesterol and blood pressure.

The chemical DEET, for example, a common ingredient in most commercial mosquito repellents, was found in 10 of the 11 lakes studied.”

Ben Mylius: Ecological Indifference in the Face of Ecological Crisis→

Minding Nature:

“A growing literature from many disciplines now views our ecological crisis not just as an “environmental issue,” but as a symptom of deep failures in our ways of thinking and being.[2] The philosopher Timothy Morton calls it “a crisis for our philosophical habits of thought, [which confronts] us with a problem that seems to defy not only our control but also our understanding.”[3]

This failure of thought, and the crisis it has caused, poses grave risks to our capacity to continue in negotiated co-existence with each other and with other species. How grave? Kevin Anderson, of the United Kingdom’s Tyndall Centre for Climate Change Research, asserts that the levels of global warming predicted are “incompatible with any reasonable characterization of an organized, equitable and civilized global community.” The Intergovernmental Panel on Climate Change—an organization not known for its sensationalist language—is now warning us about climate change’s “severe and irreversible effects.” Graham Alexander and Cathy Turner, tracking the Club of Rome’s predictions in 1972’s Limits to Growth, advise us to “expect the early stages of global collapse to start appearing soon.”[4]

These claims are undeniably significant. Many people and communities are already responding to their implications. Given the stakes of the game, we should expect nothing less. Continued indifference, from any quarter, is deeply problematic.

In this article, I propose that the majority of jurisprudence—the academic discipline that gives us our theory of what law is, of where it’s from, and how it works—is currently crippled by exactly such “ecological indifference.” Our dominant doctrine, legal positivism, claims that ecological crisis makes no difference to how we understand the content and validity of laws. It assumes that there is a sharp division between matters that are internal to our law (as a system of rules) and matters that are external to it. As a consequence, when the time comes to ask what makes our laws valid and what determines their content, ecological crisis can simply be dismissed.”

I've not thought about environmental problems in this light. But the author makes a convincing case that the social construct of our laws is fundamentally flawed. Since there is not a Lorax in our court system, our system of laws generally fails to protect that what we all depend on - Nature.

Greg Seitz: Unlocking Lake of the Woods→

St. Croix Watershed Research Station Blog:

“Lake of the Woods is the vast body of water that makes up most of the spur on Minnesota’s northern border. Sprawled across the U.S.-Canada border, it is 70 miles north-south and 60 miles east-west, contains more than 14,552 islands, and boasts 65,000 miles of shoreline. It is the size of Rhode Island and a good candidate as the “sixth Great Lake.”

Like Lake Erie and other Great Lakes, Lake of the Woods is also plagued by harmful algal blooms. Even after nutrient pollution was reduced, Lake of the Woods seems to keep getting greener.

Enormous amounts of waste discharged from paper mills on the Rainy River poured into the lake for decades, carrying phosphorus, which fed the algae. City wastewater also went straight into the river. After the Clean Water Act was passed in 1972, the waste discharges were significantly lowered and the overall cleanliness of the water entering the lake was improved.”

Jed Kolko: How Suburban Are Big American Cities?→

FiveThirtyEight:

“Our analysis showed that the single best predictor of whether someone said his or her area was urban, suburban or rural was ZIP code density. Residents of ZIP codes with more than 2,213 households per square mile typically described their area as urban. Residents of neighborhoods with 102 to 2,213 households per square mile typically called their area suburban. In ZIP codes with fewer than 102 households per square mile, residents typically said they lived in a rural area.2 The density cutoff we found between urban and suburban — 2,213 households per square mile — is roughly equal to the density of ZIP codes 22046 (Falls Church in Northern Virginia); 91367 (Woodland Hills in California’s San Fernando Valley); and 07666 (Teaneck, New Jersey).

Other factors played minor roles in predicting how respondents described where they live. Residents of very small cities and towns rarely said they lived in an urban area, even if their neighborhood was quite dense. Residents of lower-income neighborhoods with older housing stock often said they lived in an urban area, even if it was lower-density. Residents of lower-density ZIP codes with lots of businesses sometimes called their neighborhoods urban; so did residents of lower-density, higher-income ZIP codes that are next to higher-density ZIP codes. But, in general, ZIP code density alone gets us most of the way to predicting whether people say they live in an urban, suburban or rural area.”

Density makes a place vibrant. Density makes a city work. Density is the word and our answer to make better communities. Holly Whyte said "we are going to have to work with a much tighter pattern of spaces and development, and that our environment may be the better for it." 

We need to confront the need for density. I've denied and deluded myself that density was not the main issue. I've used words like 'compact', 'vibrant', and 'urban'. What is meant is more people per unit area, as well as mixed use and class. 

Higher density is better for a city. Again, Holly Whyte:

“Density also has an important bearing on the look and feel of a neighborhood. If it is urban it ought to be urban. Most of our redevelopment projects are too loose in fabric. They would look better, as well as being more economical, if the scale were tighten up... concentration is the genius of the city, its reason for being. What it needs is not less people, but more, and if this means more density we have no need to feel guilty about it. The ultimate justification for building to higher densities is not that it is more efficient in land costs, but that is can make a better city.”
