Proctor's environmental mission statement is to create and sustain a carbon neutral campus. The term carbon neutral refers to the concept of generating fewer or equal carbon emissions than the amount of carbon sequestered naturally by the environment. In reference to to our campus, this means lowering our energy consumption to a sustainable level. Sequestered carbon can be stored in the ocean, terrestrial environments, or geologic formations. Terrestrial carbon sequestration is the process of absorbing CO2 from the atmosphere into biomass and soils.

The school has put a significant amount of effort and funding into achieving this goal. The outline of the environmental mission statement includes, "sustaining a carbon-neutral footprint on campus... providing systems and services that encourage behavior, innovations, and technology that reduce our resource consumption [and] purchasing goods that are ecologically responsible." Proctor has lived this out in many ways, one of which has been the creation of the Wright Biomass Facility. Built in 2009, it replaced the school's oil furnaces with an alternative form of energy: biomass. Not only are the steam emissions from the facility clean water vapor, but the school's usage of fuel oil has dropped. Since 2006, our #4 fuel oil consumption per year has dropped 55% (from 84,334 gallons to 37,843 gallons) and our #2 fuel oil consumption per year has dropped 50.9% (81,037 gallons to 39,715 gallons).

Another step the school has taken as a community towards carbon neutrality and reducing its carbon footprint is the construction and installations of solar panels. In 2013, 273 PV (photovoltaic) panels were installed atop the Wilkins Meeting House. Generating 70,000KW annually, they have generated 225MWh of electricity since their construction. This equates to 153 tons of CO2 emissions avoided, 7,582 nights of powering the Christmas Tree at Rockefeller Center, or 8 days of powering a search engine data center. Just last year, we added another array of PV panels on four Proctor buildings and the Proctor ski area, bringing our campus solar energy production rate to over 320,000KWH per year.

Other projects Proctor has begun that work towards sustainability include Peabody Dorm (2009), which is heated and cooled via geothermal energy, Sally B (2013), which utilizes energy efficient lighting, and the construction of thee new dining hall (2016), which will also take advantage of geothermal heating.

So how close is the school towards their goal of carbon neutrality. As it turns out, we already are carbon neutral. Terrestrial carbon sequestration accounts for about 2,806mtons of CO2 per year. In 2015, our CO2 output was about 1,425.9mtons of CO2, or 1,484.5mtons of CO2 if we take rough values of ground transportation into account. As it stands right now, our campus produces 1,321.5 fewer metric tons of CO2 than the carbon neutrality threshold.

I'm excited to be a part of a community that holds environmental consciousness with such a high regard. We're in a position where it is our responsibility as contributing members of society to lower our carbon footprint as much as possible. I'm proud of our administration, trustees, faculty, and students for showing initiative to better the world from an environmental standpoint. As Jon Ferris says, "For us, the future of alternative energy at Proctor is looking bright." One point I remain curious about is the financial motivations behind these projects; how do these more efficient and cleaner forms of energy relate to the amount we pay for energy at this school?

I like the fact that at Proctor we live out our mission statements. Yesterday, on April 28th, 2016, we celebrated Eaarth Day, a time during which we all gathered at different workshops to appreciate and understand the role the environment plays in our lives. I spent the day hiking on Proctor woodlands building cairns and inukshuks and appreciating the beauty of nature.

Pandora's Promise Movie Review

Nick Ho
APES E Block
04/14/16
Information from Pandora's Promise, Documentary

Anti-nuclear activists (PC: Pandora's Promise)
Pandora's Promise, 2013, is a documentary set out to break down many of society's misconceptions regarding nuclear energy. It takes stories from a group of environmentalists explaining the history of nuclear power, as well as many of the reasons why the fear of nuclear power has been ingrained into our minds. Pandora's Promise explains how many of the dangers of nuclear power are simply unjustified, and how nuclear energy is the solution to solving global scale issues surrounding climate change.

"The fact that the whole nuclear business was started for a bomb, and used as a bomb, put this whole negative side to it."

Light-water reactor (PC: Pandora's Promise)
After the bombings on Hiroshima and Nagasaki during World War II, the idea that nuclear power's exclusive use was to destroy took hold. Soon, everyone began testing this new source of power. By the end of WWII, over 2,000 nuclear tests had taken place. Then, Admiral Rickover began to utilize this new technology for something new: submarine power. There were, in the 1950's, two kinds of reactors: breeder reactors and light-water reactors. Breeder reactors breed and recycle plutonium at a slower rate than light-water reactors, which complete nuclear processes much faster but with reduced resource efficiency and higher waste generation. Rickover opted for the light-water reactor in his submarine design.

“The enticement of the nuclear business was the fact that it was a new source of energy, a new source to generate heat, but the equivalency is huge. One pound of uranium, which is the size of my fingertip, if you could release all the energy, has the equivalent of about five thousand barrels of oil. That, to me, is amazing.”

Waste comparisons: coal, oil, hydro, solar, nuclear
(PC: Pandora's Promise)
People began to catch light of the fact that this new source of power was not only efficient, but also incredibly clean, especially compared to coal and oil processes. The first commercial nuclear plant in the US was built in Shipping Port, Pennsylvania. It was a modified version of a large submarine reactor. It was built because emissions in the area had become a cause for concern, and the low waste proposition of nuclear power was incredibly appealing. Power and light companies began to push harder for nuclear plants, and forced them to scale up quickly. Safety had become a secondary priority. Although the chances of an accident were low, they weren't no existent. 

“It must be absolutely awful to have your town wiped out, and you can’t even come and rebuild because it’s contaminated with radiation. It’s contaminated enough that it scares the shit out of you. Nobody can look you in the eye and tell you that you shouldn’t be worried. No other energy source does this, leaves huge areas contaminated by this huge invisible presence that you know can be deadly.”

Footage from inside Three Mile Island Nuclear Reactor
(PC: Pandora's Promise)
The accidents at nuclear power plants over the course of history have done a good job of instilling the innate fear of nuclear power. The first was in Three Mile Island in 1979. After a pump in the generator system broke down, many don't realize that the nuclear damage was a result of human error. Then, the Chernobyl disaster in 1986. Chernobyl was inherently unsafe. It was primarily designed to make plutonium for bombs. No nuclear stations like the one in Chernobyl were built in the West. Finally, the tsunami and earthquakes in Fukushima  (2011) caused equipment failures in the nuclear plant. 

“Misconceptions and myths about the threat of radiation persist, promoting a paralyzing fatalism among residents.”

Radiation Reading on plant in US

Radiation Reading in Chernobyl (0.92)
(PC: Pandora's Promise)
Many don't realize that the dangers of nuclear power are almost insignificant compared to the background radiation we're exposed to on a daily basis. There hasn’t been a single death from the operation of commercial nuclear reactors in the US. One would get more radiation exposure by eating a banana (from Potassium) than drinking all the water from a nuclear plant in a day. After the disaster in Chernobyl, many simply decided to ignore the restrictions and go on living in their homes. Only 28 died in 1986 due to ARS (acute radiation syndrome). 19 died from 1897-2004 of various other causes. 

"We won't get rid of nuclear weapons by forgetting how to make them. We'll get rid of them by deciding we don't want them anymore."

Countries with Nuclear Capabilities vs Countries with
Nuclear Weapons (PC: Pandora's Promise)
Another great concern is that the encouragement of nuclear energy will result in higher nuclear proliferation. This doesn't appear to be the case, however. According to the CIA, 37 countries are capable of having nuclear weapons. Only 9 actually have nuclear weapons. “We won’t get rid of nuclear weapons by forgetting how to make them. US is currently buying warheads from the Russians (now about 16,000 warheads). These warheads aren't being used during wartime, but rather being recycled for energy. So nuclear power has begun to deweaponize the world. 

“The very things made to blow up our cities are being used to power our cities.”

I personally am still skeptical about how safe nuclear radiation is. The idea that we're more affected by background radiation than by nuclear power plants is a bit of a surprise. It remains a possibility that the casualties from all of the aforementioned nuclear disasters have been covered up by governments and nuclear companies. Perhaps it is the voice in my head that has been told to think of nuclear power as dangerous. It's difficult to separate the two concepts of nuclear power and nuclear weapons. 
Regarding the overall benefits of nuclear power, I think they far outweigh the potential cons. Nuclear power is a clean source of energy that is also renewable. Looking at the Integral Fast Reactor (IFR), I understand how fuel can be recycled to continue generating nuclear power. This new reactor has passed various tests on safety, and can shut itself down. The waste is also comparably insignificant to the waste generated by coal, oil, and other fossil fuels. The amount of nuclear fuel spent in the entire US could fit in a football field if stacked to a height of about three meters. Overall, I'm excited to see what the future looks like in terms of nuclear power as an energy source and how public perception shifts over time.

Climate Change at Proctor

Nick Ho

Information from Environment Textbook, Class Notes, Internet Research, Interviews on Campus

Evidence of climate change through
melted icecaps (PC: Google Images)
We are currently studying the causes and effects of climate change in our APES class. Evidence of climate change, which is defined as an "array of changes in aspects of Earth's climate," can be found everywhere. These changes include temperature, precipitation, and storm frequency/intensity. Our class was tasked with finding evidence either supporting or disputing climate change on Proctor's campus.

Firstly, how does climate change take place? Factors that affect the rate at which the Sun's energy is received and lost are what affect the process of climate change. These factors can be natural or be direct impacts of humans. For example, an increase in the production of greenhouse gasses (like Carbon Dioxide, Methane and Chlorofluorocarbons) would result in the warming of the earth's atmosphere. This key aspect of climate change is known as global warming, which is an increase in the Earth's average temperature.

My two sources of evidence are photographs of Carr Field and around Carr House and statistics from www.accuweather.com. In taking my pictures around campus, I noticed quite a few puddles and slippery icy patches, especially relative to February of last year, during which the ground was consistently covered with snow. This shows that the temperature in Andover is rising, and that snow is melting.

 In addition to this photographic evidence of climate change, I also found evidence by looking at the
temperature from one year ago relative to the temperature today. I found that the daily temperatures  in February 2015 were simply much lower than the temperatures of this month. The highest temperature in Feb 2015 was 37F, whereas the predicted high of this month is 47F. The lowest temperatures in Andover a year ago were around 1F, whereas this year our coldest day of the month was 12F. This trend shows that this year's  February is significantly warmer than last year. Of course, the difference between the winter of one year and the winter of the following year cannot be classified as a trend. Still, these statistics point to the conclusion that climate change is real and is constantly happening.

Temperatures from February 2016 (Credits: http://www.accuweather.com/en/us/andover-mn/)
Today we see climate change everywhere: not only in our local community of Proctor but also in the world. The warming of our planet, the rise in sea-levels, and the decrease in arctic ice are all examples of global evidence of this phenomenon. Scientists are working to predict the magnitude of this change. Average global temperatures are predicted to increase by 0.5F to 8.6F by the end of the century. Precipitation levels are expected to increase, though in different proportions depending on region. The United States itself is expected to warm by up to 12F by 2100. (http://www3.epa.gov/climatechange/science/future.html) For me, it's a little bit frightening to know that this change is happening so rapidly.  A world 12F warmer could potentially be the world that my children and grandchildren grow up in. While the issues have manifested themselves in life on campus, the problem is much larger than just affecting a boarding school in New Hampshire. I was aware of climate change as an issue before writing this photo blog, simply by virtue of the fact that I live through its effects everyday: walking through puddles on my way to class or having trips to Ragged mountain canceled due to lack of snow. However, this only means that I am now more conscious of this rapidly growing issue, and makes me curious about the ways we as a community can begin to contribute to a solution.

Chasing the Inversion (and Other Atmospheric Phenomenon)

Nick Ho
APES E Block
02/14/16
Information from Environment Textbook, Class Notes, and Internet Research

Our APES class is currently studying atmospheric science, air quality, and pollution control. One key concept of this unit is thermal inversion, or temperature inversion. This term describes a process where cool air forms beneath a layer of warm air. The cool air (being denser than the warm air) resists vertical mixing and remains stable. This is unlike normal conditions, where the cool air rises and warm air sinks, creating vertical mixing.

The presence of vertical mixing allows pollutants to be carried upward and diluted. This means that pollution is less dense, and thus the conditions are less harmful. However, in thermal inversion, pollutants are prevented from being dispersed.

What does this mean for the human race, or, more specifically, big cities and metropolitan areas? Pollutants like smog are trapped in a much more condensed area. For example, London was hit with the most devastating case of thermal inversion in history back in 1952. The event, known as the "Great Smog of '52", was triggered by simple weather conditions (a period of cold weather combined with anticyclone and windless conditions). The pollutants, created from factories and coal-burning stoves, were trapped in a small area, and scientists estimate fatalities were as high as 12,000 people.

The smog that affected London is known as industrial smog, or gray smog. Unlike photochemical (or brown) smog, industrial smog is produced when industries burn coal or oil. The results include carbon dioxide, carbon monoxide, ammonium sulfate, and more. These chemicals pose risks to humans, even in small doses. For example, carbon monoxide (CO) binds to hemoglobin, preventing oxygen transport in the blood.

Today, a great deal of legislation has been passed in order to better monitor pollution in the country. The Clean Air Act of  1963 funded research and encouraged emissions standards. The Clean Air Act of 1970 set standards for emissions and provided funding for pollution-control research. Most recently, the Clean Air Act of 1990 strengthened regulations for auto emissions, toxic air pollutants, acidic deposition and stratospheric ozone depletion. Additionally, the Environmental Protection Agency (EPA) has set standards for emissions and concentrations of toxic pollutants.

Learning about thermal inversion is rather eye opening for me. I've always been aware that pollution is a growing issue, especially in highly populated areas and metropolitan cities. However, the learning about this idea is making me realize how important it is for humans to reduce pollution production. Thermal inversion can take place even without human influence. Take, for example, in the case of London's "Great Smog of '52" (where thermal inversion was brought on by purely natural occurrences). This makes it even more important that we as humans limit pollution, so when it does occur, the effects are not as devastating.

Field Trip to Andover Transfer Station (with APES E Block)

Our APES block took a trip to Andover Transfer Station this weekend where we learned about the role a transfer station plays and where the waste that we generate ends up. Transfer stations sort out and organize waste in order to figure out the next destination for each piece of trash. They play a few critical roles in the process of waste management: recovering discarded materials, finding ways to recycle them, and disposing of waste safely and effectively. Alan asked each of us to bring along a piece of trash to the Transfer Station. I brought an empty gum packet, which was non recyclable. When we arrived, I tossed it into a garbage compactor, along with several other pieces of non recyclable trash.

We then went inside where the recyclables and recoverable items were organized. There we met Debbie, who has been working at the Transfer Station for over five years now. She explained that there was a unique system in charging people who brought their trash to the Transfer Station. For example, compact fluorescent bulbs cost 50 cents each to recycle, while air conditioners and refrigerators are $10. The Transfer Station also takes much bigger items, like trucks (which cost as much as $225 if full). Debbie provided us with a fairly comprehensive guide to what can be recycled and what must be incinerated. Things like cardboard boxes, various paper based products, plastic containers #1-7 are examples of recyclables, while food stuffs and foam packaging are non recyclable and must be taken to the compactor. Debbie also explained how frustrating it was when people brought items like fluorescent lamps, because it meant she would have to disassemble them to figure out which components were reusable and which were not.

All the waste products need to end up somewhere. The journey of each piece of garbage is unique. For example, paints are brought to Franklin and Bristol twice a year, appliances are sent off to Concord, and electronics are shipped off to Rochester.
More recyclable and renewable items

After meeting Debbie, we went outside again and saw where items like tires and various metal scraps were compiled. Tires, which cost $2 each to bring to the Transfer Station, can't be incinerated with all the other non-recyclables because they contain lead, which is poisonous and would be released into the air if it was burnt. That being said, tires are not useless after serving their primary function. They can be reused as playground material, building material, erosion control, and fuel. There are also special plants where tires can be taken to be incinerated.

Our trip to the Transfer Station was enlightening and educational. I learned that there is more to the waste management process than simply having two big piles for recyclables and non recyclables. It was also a bit jarring to see the sheer amount of waste produced by a small town like Andover, whose citizens are already more environmentally conscious than many other places. Only six hundred to seven hundred people are bringing their waste to the station per week. What does this mean for the waste production of big cities like Hong Kong with populations of over seven million? The visit made me realize that humans need to minimize the amount of material in the waste stream, the easiest way being source reduction: limiting the amount we produce and create. The visit also left me with some questions about the Transfer Station. For example, is the incineration process waste-to-energy (meaning that the heat produced through incineration is then harnessed as energy)? Is the entire process profitable, or does the station only charge what's necessary to keep the station running? I hope to learn more about transfer stations in the near future.

Guest Speaker: Linn Harwell

Tonight Linn Harwell came to the Stone Chapel and spoke to a group of Proctor students from 6:30 to 7:30. She described herself at a reproductive rights activist, in addition to a women's rights activist. She also called herself a "free associator". Currently Linn is working with Hilary Clinton on her campaign because of policies Clinton supports that are in line with Linn's philosophy. Before even beginning, she explained that she wanted to have a discussion with her audience rather than lecture.

"My mantra: caring is curing; don't hesitate, just help." -Linn Harwell
Linn talks about her previous occupations (Photo Credits: Nick Ho)
One of the first topics she covered was the history of abortions from a legislative standpoint. She talked to us about Charles Lee Buxton and his wife Estelle Griswold. She explained their pivotal role in the progress of abortions becoming accepted from a legal standpoint.  The supreme court case Griswold v Conneticut (1965) allowed for abortions between married couples (in essence, repealing the Comstock laws). Additionally, a birth control center was opened in New Haven, Conneticut. Soon after, even women who were not married were permitted to abort their unborn children.

"You can never tell what your future is going to be; anything can happen." -Linn Harwell

Linn regularly attends Planned Parenthood conferences around the world; she even spoke at a conference in Bucharest, Romania. She also acted as the lead member of the League of Women's Voters, which she described as one of the most time consuming roles she's played. She recently attended the UNCPD (United Nations Conference on Population and Development) in Cairo, Egypt, which was the last scheduled conference ever.

"Sex is a big part of life. Trust me, I've had a lot of it." -Linn Harwell
Linn's Paternal Grandfather (Photo Credits: Nick Ho, Photograph property of Linn Harwell)
One of the most powerful stories Linn told tonight was of her mother, who died due to a self abortion when Linn was sixteen. During the Irish wake, Linn told us that she never shed a single tear. She said she had no time for tears, and was too stunned by the sudden loss of her mother. Linn told us that the title of the book she intends on writing and publishing is "No Tears". Her father, who was making $18 a week at the time, sent his five then motherless children off to Baltimore to whichever relatives would take them in.

While I enjoyed going and listening to Linn speak, I don't think I learned anything or gained anything by attending the discussion. I expected to hear about forms of contraception and about women's rights, but as I paid attention to Linn speak on an array of topics, I found the talk to be somewhat unorganized and had little to do with what was advertised. Even when I asked a question regarding her personal experience in dealing with the death of a loved one (due in part, of course, to not using a contraceptive), I didn't really get a comprehensive answer. Additionally, I struggled to see how the talk applied to the material we've covered so far in APES. I have a great deal of respect for Linn and what she advocates, especially for a women of her age. I think it's very amendable that she continues to fight for what she believes in, and actively participates in current events surrounding her beliefs. However, I wasn't sure her talk tonight was entirely beneficial, at least in the context of both female contraceptives and what we're learning in APES.

GUEST SPEAKER: Kent Armstrong on Bioremediation

Nick Ho '17
APES E Block
01/27/16
Information from Kent Armstrong's Lecture and Presentation

BioStryke's Website (www.biostryke.com)
This past Monday, Kent Armstrong came and spoke to our APES class about the process of bio-remediation and the role his company plays in that process. BioStryke is a company that aims to "develop, manufacture and market innovative, differentiated technologies for the environmental remediation of soils and groundwater," as described on their website.  Part of what sets them apart is the fact that their solutions to biochemical issues are much more cost-effective than other solutions available today. Kent describes what he does as "leveraging the momentum Mother Nature creates."

The issue that Kent deals with is not a simple one. Soils and groundwater sources have been contaminated with toxicants, primarily building materials (such as asbestos and silicon), metals (like lead and mercury), and organics (meaning petroleum and solvents). Kent now spends his time dealing with organics, which can be found in things like dry-cleaner solvents. These toxic substances find their way into the ground in a multitude of different ways. For example, leakage from petroleum tanks and improper disposal of waste can lead to an area becoming polluted. Kent described locations such as previous gas stations as highly probable of being contaminated. He also explained to us that these chemicals aren't something to be brushed off lightly. He showed us real world examples of where these toxins can be found, like schools and homes. We are all affected, as students, parents, home owners, etc.


Some examples of contamination
characterization strategies
The first step in the cleaning process, known as Phase I, is a "drive-by visual examination" of a site. This step only provides qualitative - not quantitative - points of evaluation. Following this is Phase II, which involves analytical testing and aids to quantify the extent of contamination. This can include testing such as soil/groundwater drilling and sampling. At this point in the process, Kent can begin to design a Remedial Action Plan (RAP), which is a part of Phase III. Here, Kent determines how any additional steps need to be executed in order to most efficiently tackle the chemical issue. This step is of a great deal of importance because the Remedial Action Plan will vary on a case by case basis. Some Phase III strategies include: soil washing, stabilization, incineration, pumping and treating, and bioremediation.

As mentioned earlier, the bioremediation process is much more cost-efficient than many alternative solutions available. One such solution is the "hog-and-haul," which is essentially taking contaminated land and moving it to a landfill, one ton at a time. While this provides a quick, easy answer to the issue of soil contamination, it is expensive and non-sustainable. The cost of moving one ton of soil through the "hog-and-haul" method is $100, compared to the $10 per ton of land it costs in the process of bioremediation. Additionally, constantly dumping toxic soil into landfills cannot continue at a constant rate, or all landfills will become too full to hold any more waste. Granted, there are downsides to bioremediating land, namely the duration of the process. While "hogging-and-hauling" is immediate, bioremediation can take three to five years.

Chlorinated Alkene Dechlorination Pathway
Bioremediation is a complex process, which involves stimulating microbes in the soil to render toxins inert, or harmless. Bugs, as Kent referred to them, are simply tiny microbes that have existed in the ground since before our time. These aerobic bugs serve the purpose of breathing in parts of harmful substances until they can no longer cause harm, much like humans breathe in oxygen. To aid this process, Kent incorporates a biostimulative additive to the mix which helps the bugs clean up the mess created by these toxins.

I personally enjoyed listening to Kent Armstrong speak about what his company does for the cleaning up of the environment. I think his solution of utilizing resources that are already available (meaning microbes) and harnessing their power shows innovation and creativity. However, I feel that despite the financial benefits of bioremediation, it will still be placed on the back burner, at least while solutions like the "hog-and haul" are available. This is because the process is so slow, and because convenience has, and I believe will, take precedence over any financial benefits.
