The PurpleAir Donation Program | April 2025

[GreenTeam (NGO Green Team I Bosnia and Herzegovina)]

What type of organization best describes you?
Non-Profit

Describe your organization.
Green Team is a non-governmental and non-profit organization from Bosnia and Herzegovina that works with youth and local communities on environmental protection, sustainable development, and responsible waste management. We operate in some of the most environmentally neglected regions of the country, giving voice to communities affected by pollution, marginalization, and a lack of institutional transparency.

Describe your project.
We aim to empower a grassroots air quality monitoring network in northwestern Bosnia and Herzegovina, where official monitoring is either completely absent or severely outdated. Air pollution in B&H is among the worst in Europe, with several cities consistently ranking among the most polluted according to WHO. Yet, rural and border communities—such as those near the planned radioactive waste site at Trgovska Gora — often remain invisible. Installing PurpleAir sensors in schools, community centers, and environmental hotspots will empower citizens with real-time data to raise awareness, engage in advocacy, and push for better air quality regulations. This project is not just about collecting numbers but about environmental justice and giving vulnerable communities the tools to protect their health and future.

Which PurpleAir model(s) are you interested in and how many would you want for your project?
We are interested in the PurpleAir PA-II-SD model, and we would need 10 units to ensure coverage across multiple municipalities, including school zones and areas exposed to air pollution. If there is a possibility for additional sensors, We are ready to scale the project and install additional sensors in partnership with our colleagues.

[richardmuraya (Richard Muraya / Infrastracker)]

1. What type of organization best describes you?
   Community-based organization (non-profit organization)

2. Describe your organization.
   The Demography Project is an independent, youth-led, non-profit organization that leverages civic technology, citizen science, collective action and grassroots journalism towards amplifying community voices and enhancing citizen capacity to participate in advancing accountable governance, participatory democracy & environmental conservation.
   It is registered in Kenya as a community-based organization under Kenya’s Community Groups registration Act No. 30 of 2022. Our volunteer membership is based at and hosted in Kihumo Village - Rungiri, off Magana/Githieya Road in the outskirts of Kikuyu Municipality, Kiambu County, Kenya.
   Our mission is to promote an enlightened and responsible Kenyan citizenry committed towards democratic principles and actively engaged in the practice of democracy and sustainable development. Our vision is Empowered communities where individuals thrive & households flourish. Our website is info.demographyproject.org ^[1]

3. Describe your project.
   Our flagship project is called Infrastracker (portmanteau for infrastructure & tracker), available on infrastracker.demographyproject.org ^[2]. It is a public domain air quality and public infrastructure monitoring project that leverages evidence-based citizen science and practical community engagement for sustainable atmospheric resource responsibility in Kenya.
   We have established a network of 5 smart weather stations installed in communities characterized as climate-vulnerable, water-scarce, disenfranchised & smallholder farmers, which offer localized data-driven insights for collective action & awareness on atmospheric & freshwater resource management. As these communities & households are also at risk of degraded air quality due to a rapid expansionist road network strategy by the Government of Kenya and domestic use of biomass for cooking & heating due to prevailing poverty rates, the Infrastracker project seeks to bridge access to informed & actionable insights on ambient air quality for reduced exposure to outdoor & indoor particulate matter emissions.
   Through Infrastracker, we are signatories to and valuable members of global and local climate action movements and coalitions including the Environmental Protection Agency’s (EPA) Air Quality Flag Program, Africa Civic-Tech Network, Citizen Science Africa Association, Clean Air Catalyst, Climate and Clean Air Coalition, among others. We have adopted a rights-based approach to promote ownership of atmospheric/air resource data for localized climate action. The topics that Infrastracker covers include air quality, physical activity and climate change by documenting the real-time exposure & adverse health/environmental risks from utilizing biomass as domestic energy source, passengers using largely-unroadworthy and loosely-regulated public transport vehicles and street-level pedestrians in selected urban areas in Kenya.
   The Infrastracker project is currently being delivered through two distinct cost-effective activities:

• Street-by-Street Air Quality (SSAQ) mapping: We deploy volunteers each with a portable air quality monitor, a portable action camera and branded t-shirts with information, education & communication (IEC) material including flyers and brochures to inform pedestrians and other road users on the real-time air quality and the negative health/environmental impacts of degraded air quality. One of the urban street-by-street air quality monitoring activities was held in Kikuyu Municipality in 2024; watch the activity here: Kikuyu Municipality Street-by-Street Air Quality Mapping;
• Public transport awareness campaign: Despite public transport being the least destructive mode of mass transportation globally, the proliferation of public service vehicles (PSVs) called matatus in Kenya’s leading cities has counterintuitively led to higher exposure to pollutants including emissions and obscenely loud music. As with the SSAQs above, we deploy portable air quality monitors, action cameras and sound monitors in matatus during both peak & off-peak periods to document air & noise pollution for policy development & implementation;

Through the April 2025 PurpleAir Donation Program, we seek to add another perspective on atmospheric resource responsibility as follows:

• Domestic & Community Air Quality monitoring: Rural households & communities like ours still rely on biomass for domestic energy (firewood, charcoal and cowdung) which especially exposes women & children to adverse air quality and its resulting health effects. Should our application be successful, we seek to: (i) deploy PurpleAir Flex monitors across our village & neighbouring villages for documentation on overall ambient air quality resulting from ongoing road construction in our vicinity and (ii) distribute PurpleAir Touch in consenting volunteer households to document the level of air pollution from biomass as domestic energy source and its health impacts on women & children. With the generated multimedia content and open air quality data, we will embark on publishing our outputs in a series of videos, infographics and other content on social media platforms to amplify the case for atmospheric resource responsibility through mass engagement. Additionally, we are developing a community engagement civic education curriculum domesticated in local languages to enhance understanding on air quality as part of climate action. We project that this will directly impact 32,000 residents of Kihumo & neighbouring villages, in addition to indirectly informing 120,000 residents of Kikuyu Municipality.

8. Which PurpleAir model(s) are you interested in and how many would you want for your project?
   Towards meeting our goals of advancing atmospheric resource responsibility in our village & neighboring communities, we are in need of:

• PurpleAir Flex (5 pax)
• PurpleAir Touch (5 pax)

1. What type of organization best describes you?
   The Becak Environmental Education Center is a 501c3 community based organization in Southwest Yonkers, NY. We focus on educating our local community about environmental challenges and advocacy.
2. Beczak has an independent Board, and we meet at least monthly in our County-owned building on the shores of the Hudson River. We involve local students, from Junior and Senior High School and local colleges, and work closely with other environmental organizations in our area on environmental projects. We frequently have lectures and other community oriented presentations, and invite other community groups to share our building’s space. We strongly believe in collaboration between community facing organizations.
3. A number of high school students and their instructor have been assembling from parts several particle sensors for outdoor use. This project has been ongoing for about three years, and we have been evaluating these sensors as compared to two of our PurpleAir mdels.
4. Describe your organization.
5. Describe your project. The Beczak Center will supervise Yonkers teachers and students in collecting particle data as part of a real word experiment. Our Disadvantaged Community surrounds a Westchester sewage treatment plant which processes 110 million gallons of County sewage daiy, and was build 47 years ago; its aerial and riverine discharges are not inspected. We have already demonstrated sharp nocturnal spikes of pm 2.5’s, an unreported new finding, and suspect microplastic blasts also, which we intend to evaluate with the aid of university pollution specialists. Our DAC/disadvantaged community has an early death rate higher than 97% of New York State’s DAC rate, which points to microplastc as well as other particle discharges, in a very wealthy County[ reported on PurpleAir as ‘Becak’.
6. **Which PurpleAir model(s) are you interested in and how many would you want for your project?**We request 4 outdoors sensors with either an internet or SD card recording capability, such as a Flex. We are grateful for your work and assistance.

[greenpelekas]

1. What type of organization best describes you? We are a non-profit environmental organization located in Corfu, Greece.
2. Describe your organization: We are a group of volunteers committed to raising environmental awareness in Corfu, and beyond. We participate in regular beach and road cleanups, educational workshops about the environment, we run a weekly recycling center (since there is no public recycling on the island), and actively engage with the local government to promote sustainable practices and positive change.
3. Describe your project: Our organization (Green Pelekas–see us on Facebook), based in Corfu, Greece, is working to address a critical gap in environmental education and awareness on the island. Corfu is a place of extraordinary natural beauty, but its environment is increasingly under threat due to over-tourism, outdated practices and systemic challenges (including the economic crisis and corruption). Air pollution is a serious and growing concern, especially during the months when open burning is legally permitted–from November 1 to May 1. During this period, residents regularly burn branches and garbage (in addition to burning wood for heating due to its affordability in comparison with electricity and gas), contributing significantly to poor air quality. Corfu is also affected by seasonal dust transport from the Sahara, making real-time air quality monitoring even more essential. Many people think islands in Greece have pristine air quality, but this is not true at all. Our air quality is often worse than in big cities around the world (we currently have one private monitor on the island).
   Our team, composed entirely of local Greeks, is actively engaged in community-based initiatives to promote sustainable alternatives and raise awareness of the environmental and health impacts of burning. We are working to introduce mulching as a viable option for agricultural waste, conduct educational campaigns and advocate for behavioral change. However, to strengthen our efforts, we need more data. We are seeking support from PurpleAir to expand our monitoring network, strengthen our environmental education programs, and ultimately contribute to the protection of Corfu’s fragile ecosystem and to the health of its residents and visitors.
4. Which PurpleAir models are you interested in and how many would you want for your project? The Classic Plus or Flex make sense for our project. We would like 5 to cover the whole island.

[Cassio_Aurelio_Suski]

What type of organization best describes you?

We are the Federal Institute of Santa Catarina, a teaching, research and extension institution in Brazil.

Describe your organization.

The IFSC is an autonomous agency linked to the Ministry of Education (MEC) through the Secretariat of Professional and Technological Education (Setec). It is a public institution whose purpose is to offer training and qualification in various areas, at various levels and types of education, as well as to conduct research and development of new processes, products and services, in conjunction with the productive sectors of Santa Catarina society.

The IFSC has 22 campuses in 20 cities in Santa Catarina: Araranguá, Caçador, Canoinhas, Chapecó, Criciúma, Florianópolis, Garopaba, Gaspar, Itajaí, Jaraguá do Sul, Joinville, Lages, Palhoça, São Carlos, São José, São Lourenço do Oeste, São Miguel do Oeste, Tubarão, Urupema and Xanxerê.

Describe your project.

In recent decades, interest in the scientific study of air quality has grown significantly due to its impact on health and well-being, leading to the implementation of specific legislation. Air quality stations stand out as an essential tool for monitoring pollution from human sources, while the study of atmospheric gases and particles gains relevance due to their role in the global climate. The increase in greenhouse gases intensifies global warming, as warned by the Intergovernmental Panel on Climate Change, and particles, known as aerosols, influence the climate by interacting with radiation, affecting cloud formation and the heat balance of the atmosphere. However, the municipality of Itajaí does not have air quality monitoring stations and, therefore, this project aims to investigate air quality, focusing on atmospheric pollution in the municipality of Itajaí - SC, during a six-month period in 2024, whose relevance is highlighted by the environmental impacts that affect both the climate and the quality of human life. The methodology will be carried out in three stages: assessment of air quality in the city of Itajaí-SC by measuring the concentrations of pollutants CO, NO2, O3, SO2, MP10 and MP2.5 based on monitoring data from low-cost air quality stations to be developed by students from the Instituto Federal de Santa Catarina; analysis of air pollution, based on the Global Air Quality Guidelines of the World Health Organization (WHO) and the National Environmental Council (CONAMA) in the city of Itajaí-SC; and assessment of the seasonality of pollutants. As a scientific contribution, the study of the dynamics of temporal and spatial variability of gas concentrations and air quality may reveal significant variations in these emissions over time, possibly associated with activities such as deforestation, burning and increased industrial activity. As a technological contribution, it is expected to develop a low-cost air quality station that will enable the execution of other scientific research.

1. What type of organisation best describes you?

Individuals on behalf of a Community.

2. Describe your organisation.

We are a group of families living in Maydena, a small town in SW Tasmania, who are being smoked out by forestry burn-offs and just want clean air to breathe.

3. Describe your project.

We are attempting to stop the unnecessary forestry and plantation burn-offs that occur after coupes are logged. We used to get warnings that these were about to happen but now they don’t bother. Often the town is swathed in thick, choking, acrid smoke for days on end. Many people have respiratory ailments and asthmatic children are too sick to go to school. We were previously advised to ‘move away’ until the smoke clears - but where are we supposed to go? Complaints to the EPA and local politicians fall on deaf ears and it is, therefore, necessary to obtain accurate air quality monitoring when these events occur in order to present our case. Photographs alone showing the awful situation are not enough, apparently. We have repeatedly asked for air quality monitors but they are not forthcoming.

4. Which Purple Air model(s) are you interested in and how many would you want for your project?

We need outdoor models - Zen or Flex. We would be grateful to receive one but two would be perfect.

PurpleAir Monitor Application

1. Who lives at this location?
Our household includes family members who are senior citizens and individuals with disabilities. Everyone in the home is generally in good health, but we are highly aware of the air quality risks due to age and sensitivity.

2. Are you involved in local fire response or support?
Yes. We have partnered with the Scott Valley Volunteer Fire Department to support local wildfire preparedness and response.

3. Please describe the collaboration.
Starting in June, we have dedicated a portion of our property for the use of the Scott Valley Volunteer Fire Department. They will use this area to build a structure and store critical fire response equipment, including water tenders and trucks. This location will serve as a forward base to respond quickly to fires in the immediate and surrounding areas.

4. What PurpleAir model is best for your location?
Our property is located at 13028 Tyler Gulch Rd., Fort Jones, CA 96032, a rural and fire-prone area. Based on our location and need for durable, outdoor air monitoring, the PurpleAir PA-II SD (or newer outdoor-rated model with Wi-Fi and SD card backup) would be the most suitable option to provide reliable, real-time data to our family and community.

[FabioB (fabio)]

1. What type of organization best describes you? We are an Italian no profit organization, called Bene Comune Cernusco, which main goal is the protection and valorization of “Commons”. We are a environmental no profit organization
2. Describe your organization. We deal with defence of Commons, which are: air, soil, water, quality of life, biodiversity, healthy environment. We are a small group of people (about 25) living in the area of Milan (Italy), absolutely volunteers, spending part of their free time in studying the laws related to environment and acting consequently in order to start actions for enquiring political decision makers and protecting the environment with practical effects.
3. Describe your project. We built ourselves some pollution measuring instruments, which are regularly posting their data online (www.benecomunecernusco.it/WordPress/pagina-sensori). They are few for the moment, but since Nord of Italy and the Milan area is one of the most polluted area in Europe, at least for air quality, we would like to increase our measuring network with some additional instruments, entering a worldwide network and improving the collected data. We will give the new instruments to our members to increase knowledge and involvement and of course improve collected data on air quality.
4. Which PurpleAir model(s) are you interested in and how many would you want for your project? We are thinking to about 10 instruments of type Purple air Classic plus

[GOdhiambo]

Type of Organization: We are Educators with keen interest in air quality assessment at the University of The Bahamas, a public university in the Bahamas.

Project Description: So far we have installed three PurpleAir sensors within the university but would like to expand the network beyond the university. Our plan is to involve the community in air quality studies by working together with the schools and community organisations within New Providence and Family Islands. Through such engagements we hope to have a more meaningful involvement and sensitization of the school children and local communities on public health and importance of air quality monitoring within their communities. There are no regulatory air quality monitoring stations in the Bahamas so, the data collected would be very useful in informing the public about the quality of air they are exposed to within their neighborhoods and health implications. These would also be very useful baseline data for future epidemiological studies

PurpleAir Model of interest: To achieve this goal we need 10-15 PurpleAir Flex to be installed at selected schools across the archipelago.

[janemfraser (Jane Fraser)]

1. What type of organization best describes you?
   Clean Air Pueblo is a project of Sustainable Pueblo, a community group, soon to be a Colorado non-profit.
2. Describe your organization.
   Clean Air Pueblo, founded in 2022, purchased PurpleAir monitors and increased the number of monitors in Pueblo County from 2 to 18. We use social media, newsletters, and community meetings to raise awareness about air quality and to help people make informed decisions to protect their health. We work with the Air Pollution Control Division of the Colorado Department of Public Health, including a project locating EPA funded air monitors in Pueblo. We work with the Pueblo fire chief and are in the process of having PurpleAir monitors installed on every fire station in Pueblo City.
3. Describe your project.
   Pueblo County is a low-income, highly impacted community, with a coal burning power plant, a cement factory, and other polluting industries. We have built strong relationships with local and state agencies to help with our work. We practice data democracy, making sure that all of our projects involve data that can be accessed by the public. We have some PurpleAir monitors that we are installing now and, looking ahead, we will need a considerable number more; we have a waiting list of households. We are seeking to improve our coverage around Pueblo County, especially in areas near known polluters. We know that we have already increased awareness and we will continue to educate people about air quality. We request ten monitors please.
4. Which PurpleAir model(s) are you interested in and how many would you want for your project?
   Ten PurpleAir Classic Plus (and power supply)
   Thank you.

[JoCHA (Jo)]

1. What type of organization best describes you?
   We are a collaboration of local public health, non-profits, and local jurisdictions located in Lane County, Oregon, USA. The lead applicant is Lane County government (Public Health division)–please note that we have a budget crisis and do not have internal funds for sensors. Big needs, big plans, no funding!

2. Describe your organization.
   Our collaboration consists of Public Health, a school district, a city’s park and recreation program, several non-profits, and a few jurisdictions. Our Public Health Emergency Preparedness Outreach Coordinator is leading this air quality monitoring team, responding to community surveys that have identified wildfire smoke as a top concern, impacting both mental and physical health.

3. Describe your project.
   Due primarily to wildfire smoke, Lane County has some of the worst air quality in the country (the American Lung Association ranked our main metro area, Eugene/Springfield, in the top 5 most polluted cities in their 2025 report). With a geographic size of Connecticut, a topography prone to air inversions, and a population experiencing high rates of poverty and asthma, our county needs to educate about the impacts of wildfire smoke on health and how to minimize exposure to it. In order to do this, we need tools like PurpleAir sensors that will show in real time how clean the air is and how various actions impact air quality. There are many outdoor sensors already available so we want to focus on placing sensors indoors to help partners know how clean the air is inside the buildings they occupy. Schools and spaces where children spend time will be prioritized for where these sensors are placed. Other locations will include spaces where other “sensitive groups” congregate such as senior centers and rural community support centers (e.g. food pantries).

Coupling the sensors with an education campaign about wildfire smoke impacts on health and ways to reduce exposure to it will motivate needed behavior changes such as closing windows, doors, and external vents when the outdoor air quality is poor and minimizing activities that generate indoor air pollution like vacuuming. We need to create an “Air Aware” culture in Lane County and having PurpleAir sensors will be a key strategy for doing this.

We had plans in place to start this work this Spring using funding from a US EPA grant but unfortunately this funding was recently canceled. The need, the motivation, and the team to do this work has not gone away.

4. Which PurpleAir model(s) are you interested in and how many would you want for your project?
   We are requesting 16-20 PurpleAir Touch (indoor sensor model).

[PurpleSubmarine (Jason)]

Hi Zanna,
This is terrible what is going on where you live. If there is only one winner for the donation program, I would like to see you get it before me. Your community is obviously being terrorized by these corporations, and I think if you set up a GiveSendGo or Gofundme, you would get donations to help beyond just Purple Air sensors. Thank you for sharing the pictures, they are worth a thousand words, and wish you success in fighting for clean air. Jason

[TheMaPortilloHome]

1. We are an individual home in West Altadena. We were affected by the Eaton Fire and wonder if we could get an air reading in our home surroundings. We have a toddler and would like to make sure they are safe.

[SmartAirBangladesh (Boudewijn Sterk)]

1. What type of organization best describes you?

A: Smart Air Bangladesh is a Social Business.

2. Describe your organization. In two to three sentences, tell us who you are and what you represent.

A: Smart Air Bangladesh is a pioneering social business leading the clean air revolution in Bangladesh. We want to transform the air we breathe. Our mission is to make clean, healthy air accessible to everyone by offering innovative, affordable air purifiers, expert knowledge, and impactful community engagement.

3. Describe your project. In a short paragraph, talk about what you want to do with PurpleAir sensors. Your answer should consider why this project is important or unique, and what its impact will be.

A: Bangladesh consistently ranks among the countries with the worst air quality in the world, with Dhaka frequently listed as one of the most polluted cities. This air pollution crisis poses serious health risks, including respiratory illnesses, heart disease, and reduced life expectancy. Despite these dangers, most people in Bangladesh do not have access to real-time local air quality data. Smart Air Bangladesh is seeking support from the PurpleAir Donation Program to establish a nationwide network of air quality sensors in both urban and rural areas of Bangladesh.
To create more awareness around air pollution and put it on the top of the government’s agenda, we need to ignite the call for clean air. The right to breathe clean air is a human right, but without a civil society claiming their rights, the government will be less likely to take action.
We are developing a mobile app especially for the purpose of making the people of Bangladesh understand the severity of the air pollution crisis. This app will translate the live Air Quality Index reading in relatable terms, such as the equivalent number of cigarettes smoked per day, which will help the public better understand the health risks associated with air pollution.
With the support of the PurpleAir Donation Program, we hope to install air quality sensors all over Bangladesh, empowering communities across Bangladesh with the tools and knowledge they need to advocate for cleaner, healthier air and catalyze a movement towards a healthier and more informed Bangladesh.

4. Which PurpleAir model(s) are you interested in, and how many would you want for your project?

A: We are interested in the PurpleAir Flex—Air Quality Monitor and would like to request 20 units for our project.

[AGC_of_Utah]

1. What type of organization best describes you? AGC of Utah is a non-profit trade association for the commercial construction industry.
2. Describe your organization. Our mission is to support Utah’s contractors by advocating for a safe, skilled, and sustainable construction workforce.

AGC of Utah is committed to promoting health and safety on job sites and in the communities we serve. Through education, workforce development, and industry collaboration, we help contractors build smarter, work safer, and improve quality of life across Utah.

We have a Southern Utah Air Quality Task force made up of contractors and city entities. We are currently seeking support for the installation of PurpleAir Monitors to help contractors and workers track air quality in real time — especially during wildfire season and high-pollution days. These monitors will assist construction teams in making informed decisions to protect their crews from harmful exposure and create a healthier work environment.
3. Describe your project. The AGC of Utah is launching a targeted initiative to distribute PurpleAir monitors throughout high-risk areas of Washington County to monitor and manage fugitive dust—an increasing concern due to rapid construction growth, arid conditions, and regional air quality challenges.

Fugitive dust, often generated by construction activity, can negatively impact both worker health and community air quality. By installing a network of PurpleAir sensors near active job sites and vulnerable residential areas, this project will allow us to:

• Track real-time dust levels
• Identify hot spots and trends
• Educate contractors and crews on best practices
• Provide actionable data to help reduce emissions
• Support local efforts to meet environmental and public health goals

This proactive approach will help the construction industry lead in environmental responsibility while protecting the health of workers and residents alike. We are seeking partners to help fund and expand this important air quality monitoring effort.
4. Which PurpleAir model(s) are you interested in and how many would you want for your project? We would prefer the PurpleAir PA-II-SD. * Dual laser particle sensors: Improves accuracy by providing redundant data.

• Wi-Fi enabled: Uploads real-time data to the PurpleAir map.
• MicroSD backup: Continues logging even if Wi-Fi is unavailable — ideal for remote sites.
• Indoor/Outdoor capable: Durable enough for construction zones with proper placement.
• Easy to install: Just needs a power outlet or portable battery system.

Optional: The PA-II-FLEX variant allows solar or PoE (Power over Ethernet) operation, which could be useful in areas without reliable power.

Washington County is roughly 2,400 square miles, but our focus is construction-related high-risk areas, not the whole county.

Here is our proposal

1. Identify high-risk zones

Focusing on:

1. Areas with ongoing or frequent construction

• High traffic/urban zones like St. George, Washington City, Hurricane, and Santa Clara
• Proximity to schools, neighborhoods, and medical facilities
• Sites with loose soils or frequent wind events

We estimate 10–20 high-activity zones across the county.

2. Monitor placement strategy

1–2 monitors per large site or zone (to detect both upwind and downwind dust levels)

• Add buffer zone monitors in neighborhoods or public spaces affected by dust drift

Estimated Total: 15–20 Monitors

• 10 for construction zones
• 5–10 for surrounding public impact areas (buffer zones, schools, parks, etc.)

Thank you for this opportunity to apply.

[EHP]

1. What type of organization best describes you?

The Environmental Health Project (EHP) is a 501c3 nonprofit organization with a mission to defend public health in the face of oil and gas development.

2. Describe your organization. In two to three sentences, tell us who you are and what you represent.

The Environmental Health Project (EHP) was founded in 2012 to address the lack of coordinated public health action in the wake of the Marcellus Shale gas drilling boom. Our unique expertise includes the development and use of sophisticated tools for air quality analysis and reporting, and providing insights into short- and long-term air pollution exposure factors from existing and proposed oil and gas facilities. By compiling research and educational materials regarding health impacts related to gas infrastructure for a wide range of audiences (e.g., grassroots organizers, public health professionals, and policymakers) we have earned a trusted reputation of providing science-based, nonpartisan public health recommendations for the purpose of limiting exposure to harmful substances associated with oil and gas development (OGD).

3. Describe your project. In a short paragraph, talk about what you want to do with PurpleAir sensors. Your answer should consider why this project is important or unique, and what its impact will be.

The Environmental HealthWatch Model (“HealthWatch”) helps communities better understand the local health impacts of shale gas development. Each HealthWatch cohort consists of communities that have existing or proposed oil or gas-related infrastructure in or near their community. EHP equips HealthWatch communities with invaluable data and information needed to better protect their health. Over one year of air quality monitoring using PurpleAir Flex monitors, participating communities learn how to analyze air quality data, reduce their exposure to harmful pollution and more effectively advocate for health protections by engaging elected officials, regulators, and site operators. Our next HealthWatch cohort begins this summer and will include two communities located in Southwestern Pennsylvania and one community in Eastern Ohio, each of which is currently impacted by well pads and/or pipeline compressor stations. Starting in July 2025, these three communities, alongside EHP staff, will engage in HealthWatch projects, including air quality monitoring, health-focused education, and policy support to further strengthen advocacy efforts. This new cohort will empower local communities to understand and limit impacts to public health.

What type of organization best describes you?
I am an individual PhD student at Northeastern University in Boston, Massachusetts, specializing in air quality modeling. I am originally from Dhaka, the capital of Bangladesh, which suffers from some of the worst air pollution in the world. Witnessing the severe health impacts of air pollution in Dhaka inspired me to pursue this field and motivates me to undertake this personal monitoring project.

Describe your organization.
Although my PhD project has access to resources for deploying a network of sensors in Boston, there is a significant lack of air quality monitoring infrastructure in Dhaka. In particular, Mohammadpur—a densely populated area with many families and schools—has no local air quality measurements, despite its high residential density and numerous high-rise buildings. This project seeks to address that gap.

Describe your project.
I plan to install one PurpleAir sensor in my family’s apartment on the 14th floor of a high-rise building to monitor ambient and semi-indoor air quality. A second sensor would be placed on the first floor, near the reception of a residential building adjacent to a main road, to capture data influenced by traffic emissions. Together, these sensors will offer valuable insights into vertical and indoor-outdoor variations in air pollution in a previously unmonitored area.

Which PurpleAir model(s) are you interested in and how many would you want for your project?
I would like to request two PurpleAir Flex sensors. This number would be sufficient to begin my personal monitoring project and provide valuable baseline data for Dhaka’s Mohammadpur area.
