UAB Students Conduct Mini Air Quality Study

UAB Students Conduct Mini Air Quality Study

Hello! We are Team Leggo My Eggo 11’s, and through our Environmental Factors of Public Health class at UAB, we had the unique opportunity to work with Gasp on a service learning project. Gasp provided us with an air monitor, called an AirBeam, which allowed us to conduct mini air quality studies to determine the air quality in different parts of Birmingham. The AirBeam measures particulate matter, which is tiny particles in the air that are 30 times smaller than hair (4 times smaller than pollen). With our data, we assisted Gasp and also learned about the reality of the air quality of our environment.

Based on our knowledge that, historically, North Birmingham has poorer air quality, we wanted to compare it to an area with expected good air quality, such as a more rural area. Therefore, our hypothesis was that the air quality in North Birmingham Park (North Birmingham) would be lower than that of Ruffner Mountain (East Birmingham).

We used the AirBeam for two hours each at both locations to gather air quality data. Below are the readings for North Birmingham Park and Ruffner Mountain.

The colors on the maps indicate the air quality: green is good; yellow is moderate; orange is unhealthy for sensitive groups; red is unhealthy.

The maps show a broad view of the air quality in both locations, but a more precise reading of air quality was taken at every second over the span of 2 hours by the AirBeam. This data was downloaded as an Excel sheet, and we were able to calculate the average particulate matter reading.

Our service learning project with Gasp allowed us to become citizen scientists—getting involved with public research and sharing our findings with others. We were able to collect data on particulate matter in North Birmingham and East Birmingham, which also allowed us to compare their particulate matter levels.

Through citizen science, we had the opportunity to do relevant research in our community, enhancing our knowledge about our environment and giving us the hope that we can improve our surroundings.

We are a group of students in UAB’s School of Public Health, and we had the opportunity to work with Gasp for a service learning project during the 2017 Fall semester. Gasp is implementing a citizen scientist program that will empower communities by allowing them to monitor the air that they breathe while at home, work, or play. We assisted Gasp by performing two mini air quality studies to demonstrate the practicality of such a program.

We were also tasked with determining which air monitor would work better for everyday air quality monitoring. Both monitors use lasers/LED lights to determine amount of particulate matter pollution in ambient air; imagine visible dust particles floating in a beam of light. Particulate matter is a mixture of fine particles in the air that can cause adverse health effects.

Pictured are maps and the particulate matter measurements for both Blount Hall (left) and the nursing construction site (right).

We began our data collection with the portable AirBeam monitor. The focus of this first study was to compare the particulate matter levels near the nursing construction site and Blount Hall Residence at UAB. As expected, we found that the air around the nursing construction site consistently had a higher level of particulate matter than Blount Hall, especially during active construction times.

After about a few weeks of data collection with AirBeam, we switched to the PurpleAir monitor. We quickly discovered a downside of this device; it can only monitor air quality from a fixed location because it must be plugged into an outlet. PurpleAir also requires an open wifi network to connect with the database. Because of these limitations, we placed the PurpleAir monitor at University House, one of the apartments close to Railroad Park in Birmingham.

Table 1 and Table 2 are the data which we collected during that time. We compared air quality at different time periods during the day. As the results showed, poor air quality occurred more frequently during evenings because of the abundance of traffic and trains.

Note: This is a continuation of Table 1.

This is where the data is collected and analyzed from the PurpleAir. There is less particulate matter at 1 pm as opposed to 5 pm.

As we completed our air study, we determined that a citizen science program is completely feasible for a city like Birmingham. We also recommend that Gasp should invest in AirBeam over PurpleAir.

Our team’s study was the trial period for AirBeam, and it worked successfully for us. We think that citizen volunteers from the Birmingham area could easily participate in this project, provided they’re given minimal training on how to set up the air monitors beforehand. Collecting accurate data is easy once AirBeam is set up.

Through our time collecting data and working with the monitors, we have determined that the monitor best equipped to handle this level of citizen science program is the AirBeam. The AirBeam is user-friendly and does not require a direct power-source at all times, unlike its PurpleAir counterpart. It also can send data to its app via Bluetooth, which made the data more readily accessible to my group and Gasp.

While the AirBeam is the more expensive of the two, we have determined that it is cost-beneficial and can certainly be used by everyday citizens. This project has been fulfilling in the sense that we feel we are making a difference by collecting useful data for Gasp, while encouraging others to join us in becoming “citizen scientists.”

Securing Environmental Justice for Northern Birmingham

Securing Environmental Justice for Northern Birmingham

Tidying up my family’s summer vegetable and flower gardens brought some calmness to a hectic week. With every season and year that passes, playing in the dirt as therapy gains greater significance for me. I recall when my boys (now teenagers) were young, giving them a shovel and dirt or just being outside would provide hours of entertainment. Maybe the simplicity of the activity throws our souls back to a slower time. I don’t know.

Residents in northern Birmingham neighborhoods are not able to benefit from this therapeutic activity. Their summers are not filled with the simplicity of moving soil around on their property. They cannot allow their children or grandchildren to dig in the yards of their homes. In fact, if their children or grandchildren inadvertently do get down in the dirt (as kids often do) they have been instructed to wash their hands and take off their shoes before coming inside. Hundreds of residential properties are contaminated with toxic chemicals. Arsenic. Lead. PAHs. Soot continues to accumulate on porches and chemical odors are commonplace.

This summer, the EPA began their investigation into Gasp’s Title VI complaint — one of many actions Gasp has taken to address the pollution. We heard in-depth interviews and testimonies from folks living in the impacted neighborhoods. Residents shared the stark realities of how legacy and ongoing pollution have altered their lives and their health.

An elderly woman who every summer for years took pride in her large, well-nurtured vegetable garden that yielded produce for her family and her neighbors shared her memories. At times, the details escaped her, but the joy her backyard garden brought her was palpable. She wonders, now that she knows about the toxic soil, if eating those vegetables year after year could have affected her families’ health. She doesn’t garden anymore.

A retired veteran who gave 30 years of service to our country spends more time outside washing the soot that accumulates on his lawn furniture than he does sitting in that furniture enjoying the outdoors. As a self-described “clean freak,” he is fairly satisfied how the water pressure of the hose cleans the soot off of his new windows, but he grows tired of this mundane chore that is as frequent as taking out the trash.

Also this summer, news broke of Oliver Robinson taking bribes from Drummond Coal and Balch & Bingham to undermine the continued cleanup of toxic contamination in Birmingham and our efforts to expand the investigation into Tarrant.

While it is not terribly shocking that big polluters and their expensive law firms engaged in nefarious activity to maintain the status quo, the silence that followed was. Where are the other elected officials denouncing Drummond Coal’s and Balch & Bingham’s immoral behavior? Where are the opinion letters or full page ads from our corporate leaders and institutions demanding for an apology or, better yet, restitution and cleanup from Drummond Coal and Balch & Bingham? Will the reach of these companies’ tentacles prevent justice from taking priority over the health of entire neighborhoods of people? The health of our children?

The summer of 2017 could have been the beginning of a paradigm shift for the most powerful corporations and institutions in our state. The federal investigation is providing the “cover” for members of the leadership class to side with the residents in northern Birmingham neighborhoods and denounce the actions of Drummond Coal and Balch & Bingham.

Although fall has officially begun, it is not too late. We need to hear from the influential voices denouncing the immoral actions of these corporations and calling for the clean up and reduction of pollution in northern Birmingham neighborhoods. Perhaps by taking action today we can ensure that the generations of tomorrow will have the benefits of a clean and healthy environment.

Start by telling the Birmingham Business Alliance to remove Drummond CEO Mike Tracy and Balch & Bingham Partner Stan Blanton from their board of directors and from barring representatives from leadership for at least two years.


My Experience at the Women’s March in Birmingham

My Experience at the Women’s March in Birmingham

When we were asked if Gasp would participate in the Women’s March in Birmingham, we enthusiastically agreed. The March stands for principles Gasp absolutely supports. Plus, it would be great to set up a table and spread the word about healthy air and clean energy to the, ahem, few hundred folks expected.

The March was scheduled to begin at 2 p.m. When I arrived at Kelly Ingram park at 12:15, people were already congregating and milling around. By 1:30, the park was packed and we were in the weeds with people at our table. The day was joyous and peaceful, and the vast number of bodies created a sense of hope and confidence that we, together, could handle the next four years. However, the anxiousness and unease of the marchers, of what is to come, was palatable.

What’s next? How do thousands of march participants and those they inspired, do something? How do we prevent the Clean Air Act from becoming obsolete? How do we ensure the free market will prevail when it comes to clean energy development? How do we protect our children’s future from the wraths of a changing climate? We can’t know exactly what to do, but a place to start, is to become an engaged citizen. Participate. Resist allowing powerful, corporate entities to be the loudest voice and accumulate their victories.

Below is an easy list of next steps to become engaged on issues related to healthy air and clean energy. Expect to be asked to do more. As we have already seen, irresponsible decisions are being made that will impact our planet — your family’s air, water and future. While we brace ourselves, consider starting here:

1. Sign Up

Get on the Gasp mailing list to receive news about air pollution, climate change, renewable energy, and other issues that affect our health and our environment. Already on our list? Share with a friend who might be interested in healthy air and clean energy issues.

2. Become a Member

Join the more than 300 members of Gasp by making a donation at any level. I am a personal fan of giving recurring, monthly donations, since they allow you to give larger, annual donations at small amounts over time.

3. Call & Write Elected Officials

Sign our petitions; write letters to Congress in support of (or in opposition to) specific policy proposals; make phone calls to demand action. Pro-tip: Save your Senators and Representative in your phone’s contacts.

4. Volunteer

Sign up to help with events, become a citizen scientist, give a presentation (or invite us to give a presentation at your church, civic group. etc) assist with community outreach, and more.

Thanks to all the organizers of the Alabama Women’s March for pulling off a well attended, energizing event. It was an honor to be involved. And thanks to our wonderful volunteers, Adriane and Keskia, for helping us out!

Below are the remarks I made at the Alabama Women’s March in Birmingham reflecting on the unity principle of environmental justice:

Margaret Mead said, Never doubt that a small group of highly committed individuals can change the world, indeed they are the only ones who ever have.

Everybody deserves clean healthy air, regardless of their ZIP code. Unfortunately, in our country and here in Alabama, where you live can determine how healthy your air is to breathe.

Where you live can determine whether or not your child needs an inhaler to get through their day.

We want the best available technologies to be deployed to dramatically reduce toxic emissions

We want the Clean Air Act, that is responsible for the dramatic improvement to our air quality over the years to remain intact — to be improved based on scientific research — not dismantled by those who wield their power and money freely

We want agencies to consider whether or not a polluting facility is disproportionately impacting low income and/or minority communities before they give that facility a permit to pollute.

Water is Life.

Alabama is home to some of the most biologically diverse rivers in the world, yet a few politically powerful entities have a tight grip of control — over how our water is managed. The water in the state belongs to all of us.

In Alabama, we have no plan for managing this precious resource.

We want to be fully prepared for the next extreme drought — which we know will be coming…

The rivers and waters of Alabama should be managed responsibly, to be protected from toxic waste, from irresponsible actors who use our rivers and streams as a dumping ground

We want all the fish in our waters to be healthy and edible for everyone, including pregnant women, children, and sustenance fisherman. We don’t want our fish loaded with dangerous toxins.

We want the health of our water and air to take priority over powerful polluting entities financial interests.

We stand behind the thousands of climatologists around the world who tell us the climate is changing. We believe what science is showing us: our planet’s climate is changing, and the most vulnerable among us will again be disproportionately impacted. The time to act is now.

The Clean Power Plan needs to remain intact to reduce harmful carbon emissions.
We want to harness the energy of the sun to combat climate change. In Alabama, powerful interests are trying to hold this industry back, instead of letting the free market prevail.

We want those in power to to make decisions based on the creed, “We did not inherit the earth from our parents and grandparents, we are borrowing it from our children and grandchildren.”

Help Gasp Fight for Environmental Justice

Help Gasp Fight for Environmental Justice

Some communities in our country suffer from a larger burden of environmental hazards than others. These areas are referred to as environmental justice (EJ) communities. While more attention has been given to EJ communities as of late, tangible, specific changes to reduce the burden of toxic exposures in EJ communities has been non-existent. For example, neighborhoods in the northern Birmingham area continue to suffer from industrial pollution despite being named an EJ community by the Environmental Protection Agency (EPA). EPA’s Office of Civil Rights has “accepted” two Title VI Complaints against the Jefferson County Department of Health. But the investigation has not started.

In an attempt to improve the health and quality of life for residents of EJ communities, EPA has released the “2020 EJ Action Agenda,” which is their 2016-2020 strategic plan for environmental justice. Gasp will weigh in on this Agenda to give Birmingham and our members a voice. We’re looking for neighborhood associations, churches, and other groups that want to see strong improvements to EPA’s handling of environmental justice to sign on to our comments or submit their own.

The 2020 EJ Action Agenda will help the EPA integrate environmental justice into everything they do. This vision is intended to help make vulnerable, economically challenged, and environmentally overburdened communities cleaner and healthier places to live.

The three main goals of the plan are:

  1. To deepen environmental justice practices within every EPA office and region.
  2. To collaborate more with communities, governments, and stakeholders.
  3. To demonstrate progress on critical national environmental justice challenges.

Focus of Gasp’s EJ 2020 comments:

  • The EPA should use environmental justice factors to select communities with the greatest need to receive additional attention and resources.
  • Plan EJ 2020 should build Title VI compliance and enforcement into all aspects of EPA’s operations, and should establish a system by which the EPA will resolve all Title VI civil rights complaints in a timely manner.
  • The Office of Environmental Justice (OEJ) and the Office of Civil Rights (OCR) should coordinate and communicate more when on the ground in vulnerable communities in order to create a clear role for the OEJ to provide their expertise.
  • The EPA should strengthen oversight of state and local agencies administering federal environmental laws and prioritize the best practices in permitting, rulemaking, and enforcement. Gasp supports EPA’s objective to enhance work with regulatory partners in overburdened communities. The Alabama Department of Environmental Management and the Jefferson County Department of Health will surely benefit from increased collaboration with EPA to address disparate impacts of illegal pollution on communities.
  • As part of Goal II, especially in the Northern Birmingham communities, EPA could build the capacity of communities to take part in critical environmental and public health issues that impact them by, for example, holding trainings and distributing materials and resources well in advance of Title V permit renewals in order to enable community members to comment meaningfully on Title V permit renewal applications.
  • Gasp fully supports and welcomes EPA’s focus on developing innovative monitoring tools and technological solutions to environmental problems. Citizen science will empower overburdened communities and thus should continue to be an integral part of EPA’s EJ Action Agenda.

Here’s what you can do:

It is important for Birmingham citizens to raise their voice for a stronger EPA Environmental Justice Program. Local regulatory agencies look to EPA for guidance when determining how to handle environmental justice issues. Comments are due to the EPA July 28.

Please consider supporting a stronger EPA environmental justice program by either signing on to Gasp’s comments, or submitting your own. We are also looking for neighborhood associations, churches and civic organizations to support stronger EJ policies. And please give us suggestions of groups we can contact to ask for support.

To sign on to Gasp’s EJ 2020 comments, please contact Haley Lewis no later than July 27. You may submit your own written comments electronically to:, or via mail to:
