Logging Complex Odors

by sarasage | 8 months ago | 5 | 8

During the summer, our fellowship team logged ambient odors on field sheets to accompany data from our gas monitors. As we are closing up the fellowship and looking through the data, we want to know what quality of odors are coming into our community from a nearby landfill - and if there are patterns or trends in the type, frequency or accompanying factors.

In the past, we defined odors like decomposing waste, as "green waste" or "trash," which are subjective descriptors. I was inspired to reduce the odors to their basic components, remembering a toy my daughter loved when she was younger. It was a perfume science lab, wherein you could make fragrances using approximately 6 different base odors (vanilla, lemon, sandalwood, etc).

Perfume Science

I identified the base odors that emanate from a nearby landfill:

  1. Sweet
  2. Rot
  3. Fecal
  4. Ammonia
  5. Chemical
  6. Sulfur

Odors that we used to describe as "kitchen trash" became, "sweet" and "rot" because those are the primary components of that particular odor. Instead of "wastewater sludge," we described the smell as "fecal" and "ammonia."

Wheel of Misfortune

With this method, we can enter data into categories on a spreadsheet that we can analyze at a later time:

Announcing New Fellowship Team: Game Over Formosa!

by stevie with TravisLondon | 8 months ago | 1 | 3

The Project Issue: Proposed Formosa Plastics Plant in St. James, Louisiana

The St. James parish alongside the Mississippi river in southern Louisiana is a historically black and now elder community with 15.6% of residents living below the poverty line. Many of the residents trace their lineage back to the enslaved families who worked the plantations along the banks of the Mississippi. The land is filled with historic and sacred sights including the unmarked graves of slaves. For years, St. James Parish has been extremely overburdened by industrial pollution. The 258 square miles of St. James hosts no less than 11 industrial facilities that are large enough to be required to report their pollution to the federal EPA each year. These include refineries, a fertilizer plant, a steel company, an asphalt company, and several chemical companies. The list of chemicals emitted into the air, water and soil in St. James and surrounding areas include cancer causing dioxins, asbestos, chlorine, lead, mercury, acids, benzene, toluene, methanol, ethylene, and hydrogen sulfide to name a few (the EPA’s TRI database report for St. James Parish, 2020).

For years, the community, already struggling with extreme pollution, has been fighting to keep out new industry, particularly one plant called Formosa Plastics slated to be a 2,500 acre project just one mile from an elementary school (Center for Biological Diversity). As a company, Formosa has been a historic bad actor (see follow up post on Formosa Around the World). Their Texas plant released “thousands of plastic pellets and other pollutants into Lavaca Bay and other nearby waterways.” These spills were brought to court in a private citizens suit by Dianne Wilson and nonprofit Texas Rio Grande Legal Aid resulting in a $50 million settlement, “the largest in U.S. history involving a private citizen's lawsuit against an industrial polluter under federal clean air and water laws” (Texas Tribune December 3, 2019). Formosa plants around the world have also experienced several explosions causing community evacuations, major chemical releases, and even worker deaths (see follow up post).

On August 18, 2021 the US Army Corps of Engineers announced it would “require a full “environmental impact statement” for the massive petrochemical complex Formosa Plastics proposes to build in St. James Parish, Louisiana. The decision is a major victory for opponents of the plant, who sued to block the project in January 2020 and convinced the Army Corps to suspend its permit” in fall of 2019 (Center for Biological Diversity). An impact statement can take anywhere from 51 days to 3 years to do. For this statement, they’ll be “required to assess the impact of a proposed project on the physical, cultural, and human environments affected by the proposed project… [including] provid[ing] a baseline for understanding the current environmental situation in relation to the Proposed Action.” The EIS should also include air, water, historical and economic impacts of the project ( The EIS should also trigger a new comment period for community members.

The aim for this project is to regularly collect particulate matter and other air quality monitoring data to grow the body of evidence on the existing levels of pollution to show the pollution burden already borne by the St. James Parish community. We aim for this information to be used to educate the community, and provide scientific evidence for why further pollution sources such as the Formosa Plastics, should not be developed in this community.

Project Goals:

The goals of this project are to:

A: Regularly collect particulate matter air quality monitoring data to grow the body of evidence on the existing levels of pollution to show the burden already borne by the Donaldsonville and St. James Parish communities. We aim for this information to be used to educate the community, and provide scientific evidence for why further pollution sources such as the Formosa Plastics, should not be developed in this community.

B: Regularly share project updates including monitoring methods, tools, challenges, data and questions on Public Lab and in other project identified spaces as appropriate.

C: Work towards advocacy around the air pollution issue in Donaldsonville and St. James Parish by working to understand local permits, zoning, and legal landscape in aim of gathering information for the upcoming Environmental Impact Statement and community input for the open comment period.

D: Work towards project pass off and longevity by focusing on communications materials around the monitoring results, advocacy information, and how people can get involved and monitor. We will use this to put together information sessions, as well as pamphlets and print materials.

The Project Issue: Mountaintop Removal Coal Mining in West Virginia

For well over a century the coal industry has exploited the people and natural resources of West Virginia. The technology they have developed over the past four decades specifically has allowed them to destroy and poison the environment to an almost unbelievable extent, all in the name of maximizing profit. Large scale surface mining, also known as mountaintop removal not only deforests thousands of acres per mine site, but completely destroys the landscape leaving behind only bare rock and rubble. The biologically diverse forests that used to set where these mines now exist can never be replaced, the topsoil that allowed them to exist is now buried under valley fills. The bedrock that once formed some of the oldest mountains on the planet is blasted apart and turned into toxic dust clouds that settle on the communities below.

The state regulatory agency, the West Virginia Department of Environmental protection has been in the pocket of the coal industry since its conception. This makes it difficult to hold the industry accountable to the relatively lax environmental laws, but not impossible. Over the years, Coal River Mountain Watch has discovered a handful of methods in the pursuit of chipping away at the profit margins of coal companies. One of the most successful tactics has been in observing, documenting, and monitoring mining activity and reporting on them to the DEP. The intent behind this fellowship team is to support our continued work against the coal industry using drones and other forms of observation to document violations of environmental law, and pressure the DEP to take appropriate action. The fines incurred by the coal company are a pittance and are factored into the cost of doing business.

The main goal of this work is to make the companies pull workers and equipment away from actively mining coal in order to fix the problems they created.

In this project, we aim to:

  • Monitor active mine sites from the ground and via drone.
  • Research environmental regulations and identify tactics that concerned citizens in communities around surface mines can use to document illegal actions and permit violations by the mining companies.
  • Communicate our findings to the Department of Environmental Protection and follow up with them to raise the pressure on the agency to take action.
  • Create a videos examining the state of abandoned and active mines in the area on and around Coal River Mountain, and describe the tactics that can be used to hold the industry accountable.

Community Organizing Fellow and Project Lead: Junior Walk

Gas-Calibrated Monitor Explainer

by sarasage with denissebn_06 | 12 months ago | 0 | 2

Haz click aqui para leer el contenido de esta página en español.

Gas-calibrated monitors are a class of air monitoring equipment that use canisters of known quantities of gas(es) to assess and ensure the accuracy of an instrument.

image description

For example, if you have an air quality monitor that measures sulfur dioxide (SO2), you measure the operation of the SO2 sensor with a canister that has a lab-certified quantity of SO2. A gas-calibrated instrument is typically calibrated every 60-90 days, depending on usage. These instruments also need to be bump tested -- bump tests check the device's accuracy before each use. A dedicated calibration station is a must when using these instruments.

image description

Through this technology, we are monitoring airborne:

  • Hydrogen sulfide (H2S)
  • Methane (CH4)
  • Volatile organic compounds totals (tVOC)
  • Isobutylene (C4H8)
  • Carbon monoxide (CO)
  • Oxygen (O2)
  • Sulfur dioxide (SO2)
  • Formaldehyde (CH2O)
  • Ammonia (NH3)

Because the monitors are calibrated and bump tested regularly, they are highly accurate. Unfortunately, they are time-consuming, complicated, and costly, making them a challenging choice for community science AQ monitoring.

image description

Additionally, because they are handheld, data collection requires personnel in the field to record data. These monitors have a photoionization lamp that gets hot and can overheat during hot summer temperatures. When the ambient temperature is too high, the instruments shut off automatically to protect them from overheating. They also do not have the ability to record GPS data, so geospatial mapping has been challenging. These are all problems we are working on minimizing and we welcome input from the Public Lab community.

image description

The benefit of using gas-calibrated monitors is that when they are serviced properly, you can accurately test for singular airborne pollutants.

As a side note, VVAMP is moving toward installing Purple Air sensors, as fire season is here in SoCal. Purple Air sensors do not monitor gases, but particulate matter. Follow our progress here!

VVAMP is monitoring ambient air gases adjacent to a massive landfill in Los Angeles County. The town of Val Verde is one of the communities affected by the proximity to the landfill. The Newhall Ranch community, which is currently in development, will also be affected. The issues with siting the landfill in this location are that it is located near a historic environmental justice community, and away from the population center of Los Angeles which it serves. The trucks that transport waste to the landfill from waste sorting facilities use diesel fuel that contributes to particulate pollution to communities sited near the I-5 and elsewhere. Los Angeles County has a county-owned, waste-by-rail facility that is permitted, yet unused. The county has instead relied on privately owned landfills for waste management.

Explicación sobre el monitor de Gas calibrado

Los monitores de gas calibrado son un tipo de equipo para monitoreo de aire que usa latas / bote / frasco de cantidades conocidas de gas o gases para evaluar y asegurar la precisión de un instrumento.

image description

Por ejemplo, si tú tienes un monitor de calidad de aire que mide dióxido de azufre (SO2), tú mides el funcionamiento del sensor de SO2 con un frasco que tiene la cantidad de SO2 certificada por un laboratorio. Un instrumento de gas calibrado se calibra típicamente cada 60-90 días, dependiendo del uso. Estos instrumentos también necesitan una prueba funcional. Las pruebas funcionales verifican la precisión del dispositivo antes de cada uso. Una estación de calibración bien dedicada es una necesidad cuando se usan estos instrumentos.

image description

A través de esta tecnología, estamos monitoreando gases llevados por el aire:

  • Sulfuro de hidrógeno (H2S)
  • Metano (CH4)
  • Totales de compuestos orgánicos volátiles (tVOC)
  • Isobutileno (C4H8)
  • Monóxido de carbono (CO)
  • Oxígeno (O2)
  • Dióxido de azufre (SO2)
  • Formaldehído (CH2O)
  • Amoníaco (NH3)

Porque estos monitores son calibrados y probados funcionalmente regularmente, son muy precisos. Desafortunadamente, consumen mucho tiempo, son complicados, y costosos, siendo una elección desafiante para la ciencia comunitaria de monitoreo de calidad de aire.

image description

Adicionalmente, porque son portátiles, la colección de datos requiere personal de campo para recuperar y juntar los datos. Estos monitores tienen una lámpara de fotoionización que se pone muy caliente y se pueden sobre calentar durante las temperaturas calientes de verano. Cuando la temperatura ambiente es muy alta, los instrumentos se apagan automáticamente para proteger el equipo y evitar el sobrecalentamiento. Los instrumentos, también no tienen la habilidad de grabar puntos GPS, así que el mapeo geoespacial ha sido desafiante. Estos son los problemas que estamos trabajando para minimizar y estamos abiertos a sugerencias de parte de la comunidad de Laboratorio Publico.

image description

El beneficio de usar monitores de gas calibrado es que cuando se preparan apropiadamente, tú puedes hacer testeos precisos para un contaminante llevado por el aire en específico.

Como nota aparte, VVAMP está avanzando con la instalación de sensores de "Aire morado", la temporada de incendios está acá en el sur de California. Sensores de "Aire morado" no monitorean gases, pero sí material particulado. ¡Sigue nuestro progreso acá!

image description

VVAMP está monitoreando gases en el aire del ambiente local adyacente a un relleno sanitario masivo en el condado de Los ángeles. El pueblo de Val Verde es una de las comunidades afectadas por la proximidad del relleno. La comunidad del Rancho de Newhall, que actualmente está en desarrollo, estará también afectada. Los problemas de la ubicación del relleno sanitario, es que está ubicado cerca de una comunidad histórica de justicia ambiental, y afuera de la población central de Los Ángeles a la que sirve. Los camiones que transportan desechos hacia el relleno sanitario desde las instalaciones de clasificación usan gasolina diesel que contribuye a la contaminación de partículas en las comunidades situadas cerca de la carretera I-5 y otras partes. El condado de Los Ángeles es dueño, y tiene el permiso para transportar desechos por ferrocarril, y aun así no se usa. El condado en vez depende de rellenos sanitarios de propiedad privada para la gestión de residuos.
