Illinois EPA looking to cut back on air monitoring

Facing the prospect of budget cuts, the Illinois Environmental Protection Agency has drafted plans to reduce the number of air quality sensors throughout the state.

The 2014 Ambient Air Monitoring Plan, drafted in May by the IEPA, recommends that the agency discontinue one sulfur monitoring site, one particulate matter monitor, and three lead monitoring sites.

"The proposed 2014 network plan provides select discontinuations from the plan approved by US EPA and operated in 2013," the plan reads (PDF). "The design of the monitoring network for 2014 has also been based upon the assumption that funding to support the monitoring program is likely to be reduced in fiscal year 2014 and that all efforts would be made to keep as much of the network intact as possible."

The particulate matter monitor is located atop Washington High School in the South Side of Chicago, one of the more polluted parts of the city. It specifically measures the amount of particles under 10 micrometers in diameter, known as PM 10, which can damage lung tissue, cause cancer, and lead to death.

According to the IEPA's 2011 annual air report (2012 and 2013 reports are not available from the website), this was the same monitoring station that observed the highest annual average concentration of airborne cadmium and sulfur in the state for that year.

Why the word "drone" is scaring neighbors, creating bad legislation, and blocking an economic boom.

Sensationalist coverage and fabricated illustrations have cemented the word "drone" as a weapon in the public psyche. But it may not be too late to change public opinion about the technology behind the word.

A few years ago, a colleague and her husband, an ex-helicopter pilot, realized a tectonic shift was disrupting industries in which they had devoted entire careers.

This disruption had a passing resemblance to what happened to other American industries. The hard work once done by skilled, human hands was now being automated by the calculating actuators of a machine.

Automation had long since dominated the appliance, automotive, and electronics industries. But this was a brand new territory – aviation.

The reduced price and size, and the increased reliability and capability of processors, sensors and batteries meant unmanned aviation had been unleashed. A nouveau DIY revolution meant that basements and garages were once again incubating nascent technology, just as they did in the 1970s when the personal computer was being developed.

The silver lining is that the cost of search and rescue, disaster relief, monitoring wildlife, guarding endangered animals from being poached, and even medication delivery to underserved populations all could be slashed.

Like many other small startups in the unmanned aviation industry, my friend and her husband saw an opportunity. And despite criticism of slow progress on regulations, the Federal Aviation Administration also sees it. The FAA estimates that the market for commercial unmanned aerial systems will eventually reach $90 billion.

The Association for Unmanned Vehicles and Systems International (AUVSI) believes there will be an economic impact of $13.6 billion within 3 years that unmanned aircraft are integrated into the national airspace.

Where to start? What better way to get acquainted to the industry than attend one of the premier industry conference in the nation, hosted by AUVSI?

She learned about new applications for unmanned aircraft. She listened to a UAV operator who used his homemade robotic aircraft to assess flood damage in Thailand. The information gathered from the aerial vehicle allowed the government to make decisions that mitigated flooding in the country’s capital.

This was great. But when it came to talk shop, things became awkward when she used a five-letter word that began with the letter “d.”

“The conversation would just stop,” she said. “Just completely stop dead.”

Civilian whose drone was shot down over Turkey protests comes back for more video

Since May 28, citizens in Turkey have been protesting their government's plan to raze a park in the country's capital, and replace it with a commercial center and military barracks. Violence in Taksim Gezi Park has escalated much since then, with police hitting protesters with tear gas, rubber bullets, and water cannons.

On June 13, I reported on sUASNews.com that a civilian had been filming clashes between police and demonstrators from the sky with an RC aircraft, and that the drone had been shot out of the sky by police.

The drone's pilot, who goes by the name Jenk, was able to capture dramatic footage of the violence from the sky before his aircraft went down on June 11. Video from his DJI Phantom showed billowing smoke, and demonstrators scrambling to find cover from high-pressure water hoses and lobbing back the gas canisters from the riot police.

Now, it appears that Jenk has either repaired his drone or found a new one, and has returned to the Gezi Park protests to capture more aerial footage.

Finding a definition and purpose for sensor journalism at the Tow Center

Before I left for the Tow Center's sensor journalism workshop at Columbia University last weekend, my wife and I hosted some friends for a spinach lasagna dinner. On the stack of books my wife was researching for her dissertation on toxins in science fiction, sat my latest obsession, the DustDuino sensor node.

While we ate, the node's tiny LED lights blinked away as it took particulate matter readings every 30 seconds. A friend pointed out the interesting juxtaposition of the pollution monitor siting on a copy of Rachel Carson's Silent Spring. Our friend's husband, an entomologist, asked what it was all about.

"Part of the idea is to have people make these all over the country, especially places with bad air," I said.

"Interesting," he said. "You know... that doesn't sound much like journalism," he said. "It sounds like research."

I thought about it for a moment, and took a sip of the lemon-and-bourbon cocktail my wife prepared. I didn't have a good answer.

"Journalists are kind of unemployed at the moment, so we're looking for other things to do," I replied.

For me at least, the Tow Center's workshop helped find an answer to that question, and provide a deffinition and goal for sensor journalism. About 50 folks with backgrounds in journalism, science, architecture, community informatics, and computer technology came to the Tow Center's first sensor journalism workshop on June 1-2.

I owe a big debt to the organizers of this event: Emily Bell, the Tow Center director; Fergus Pitt, Tow research fellow; Taylor Owen, Tow research director; along with Laura Kurgan, director of the spatial design lab at Columbia; and Chris Van Der Walt and Sara Jayne Farmer of Change Assembly, Inc.

Step-by-step guide to programming the RN-XV WiFi module for Arduino

The Arduino prototyping standard has been around for about 6 years now, and has proven to be immensely useful for sensing devices. It's the heart of the DustDuino and many other sensor nodes.

But for all the flexibility that the Arduino provides for collecting data about the environment, there still isn't a reasonably-priced, reliable shield to send data via WiFi.

The official Arduino WiFi shield, while well-supported, costs around $85. That's a pretty high price to connect a $4.50 chip to a network. Cheaper options such as the WiFly shield do exist, but some of the libraries supporting these devices are difficult to decipher or unstable, if they exist at all.

I spent a long time myself looking for a cheap, effective WiFi solution for the Arduino platform, and I've been very pleased with the $35 RN-XV module.

DustDuino: A plan to crowdsource environmental reporting with low-cost dust sensors

There's some good news in the air. Or, well, about the air.

Last month, the American Lung Association released its 2013 report on the quality of the nation's air. The Lung Association's "State of the Air" report shows the country's air is continuing to improve.

The Lung Association attributes healthier air as a "direct result of emissions reductions from the transition to cleaner diesel fuels and engines and coal-fired power plants, especially in the eastern United States."

That much is good. But there's much room for improvement.

According to the report, "Of the 25 cities with the worst problem with spikes in particle pollution, fourteen had more days or worse problems in 2009-2011 than in the previous report." Six cities included in the report had their worst year ever (over the 14 years the report has been made) for short-term spikes in particulates.

Chicago, home to some of the dirtiest coal-fired power plants in the nation, continued to flunk both daily and annual levels of particulate pollution. This was where I did my own environmental investigation on how the Fisk coal-fired power plant threatened the health of the Pilsen neighborhood (see: "Battle in the Barrio").

The Fisk station dumped 755 tons of particulates into the air on an annual basis, according to a pollution report from the Environmental Protection Agency. The Clean Air Task Force found that the plant contributed to 15 deaths and 23 heart attacks annually, a figure based on EPA data.

The residents of Pilsen eventually won their battle, and the Fisk station was closed. EPA tests after the plant closure showed the particulate and radiation levels had returned to city-wide norms. Interestingly, one of the EPA air quality monitors was mounted in a baby stroller to measure levels around the perimeter of the plant.

Pilsen didn't have air quality monitors to begin with, though. Its residents had to lobby the Illinois EPA before the state placed an air monitor atop an elementary school in the neighborhood. The readings from the monitor led the IEPA to declare Pilsen a "nonattainment" zone for lead, a particulate which impairs the IQ, learning capabilities, and memory of children.

Columbia's Tow Center is brainstorming sensor journalism prospects in workshop

In a little over a week, the Tow Center for Digital Journalism at Columbia University will be organizing experts across multiple disciplines, from around the country, to come up with low-cost, widely-distributable solutions for sensor journalism.

For their Sensor Journalism Weekend (June 1-2), the Tow Center will host discussions on the "pre-history, current practice and opportunities for sensors in journalism," in anticipation of a pilot sensor journalism project to be conducted over the summer.

According to Tow's calendar, there will be "technical, ethical, theoretical and practical resources available, demonstrations of current sensing equipment and opportunities to expand links throughout the community of people working in the field." Folks from the Spatial Information Design Laboratory in the Graduate School of Architecture, Planning and Preservation at Columbia University will be in attendance.
