BENICIA COMMUNITY
AIR MONITORING PROGRAM

The Benicia Community Air Monitoring Program (BCAMP) has been established to monitor
local air quality in real-time, operate a website, and provide education on health as related to air quality.

BCAMP is a 501(c)(3) non-profit corporation.

Donations to BCAMP are tax deductible and will help us fund future operations.

Gauge Color Indicator	System status as of May 14 2025, 7:10 PM
Benzene No detection	Loading...
Benzene is a volatile organic compound (VOC) on the State of California's "Prop 65" list of known chemical carcinogens. Benzene is a neurotoxin and can be found at low detections in ambient air. Signs of benzene exposure can be dizziness, headaches, nausea, irritation to eyes and mucous membranes. Benzene is a constituent of crude oil and is associated to refinery emissions, petroleum product storage, vehicle tailpipe emissions, gas stations, other industrial emission sources, solvents, woodsmoke, tobacco smoking tobacco and cigarette smoke. Long-term exposures to airborne benzene can be a cause of blood cancers and developmental/reproductive problems. Acute benzene poisoning can lead to heart arrhythmias, respiratory tract inflammation, pulmonary blood clots and hemorrhages, and affect kidneys and brain function.
Black Carbon 0.1 ug/m3	Loading...
When inhaled, particles of soot (such as from tailpipe emissions and burning charcoal), may lead to increased breathing difficulty and asthma attacks, and affect heart and circulatory system functions, including blood pressure/hypertension. Repeated exposures may require emergency room visits (Scientists have not yet concluded how black carbon affects health).
Sulfur Dioxide No detection	Loading...
Short term exposure can cause lung problems, burning of nose and throat. Longer term effects of chronic exposures are decreased lung function and chronic asthma.
Toluene No detection	Loading...
Short term exposure can cause eye and nose irritation, confusion, headaches, anxiety, dizziness, and insomnia. More serious effects from chronic exposures may include kidney and liver damage, and possibly infertility.
Xylene No detection	Loading...
Exposure for any amount of time can cause headaches, lack of coordination, confusion and dizziness. Exposure to high concentrations can cause skin, eye, nose, throat irritation, lung problems, breathing difficulty, memory loss, liver and kidney changes.
PM1 1.2 ug/m3	Loading...

PM10 8.8 ug/m3	Loading...
PM10 includes dust from construction sites, landfills and agriculture, wildfires and brush/waste burning, industrial sources, wind-blown dust from open lands, pollen and fragments of bacteria. Short-term exposures to PM10 have been associated primarily with worsening of respiratory diseases, including asthma and chronic obstructive pulmonary disease (COPD), leading to hospitalization and emergency department visits.
PM2.5 3 ug/m3	Loading...
Tiniest, invisible particles, at 2.5 microns or less (“PM2.5”) are most dangerous for health. PM2.5 can't be expelled by coughing, because the particulates travel deep into the lungs, lodging in tissues and releasing into the bloodstream other air toxins attached to them. Chronic exposure to PM2.5 can lead to blood clots, stroke and heart attacks. People with compromised immune systems may be more susceptible to viruses and bacterial infections, which can lead to pneumonia in children and older people.
H2S Low Signal	Loading...
Hydrogen sulfide can usually be smelled at low levels of concentration with immediate symptoms such as burning eyes, coughing, fatigue, and shortness of breath. At moderate levels of concentration, exposure can cause severe eye and respiratory irritation, including fluid in the lungs, nausea and staggering. The results of exposure to high levels of concentration can be life threatening with effects such as the inability to breathe, convulsions, unconsciousness, coma, and death. As prolonged exposure may result in the inability to distinguish the odor at all, measuring levels of concentration is invaluable in providing early detection to mitigate long-term health effects.

The purpose of this page is to evaluate the ability of the equipment installed as part of the Rodeo Fence-line Air Monitoring Program to detect and quantify gases that are ever-present in the air we breathe. The U.S. Environmental Protection Agency (EPA) suggests this is one way to assess the validity of data from fence-line air monitoring systems. Methane, nitrous oxide, and ozone are examples of gases that are always present. As per the EPA, should an air monitoring system fail to detect these gases within specific concentration ranges, the credibility of the data should be questioned.

In addition, at the request of individuals living in the community of Rodeo, the BCAMP monitoring program has relocated an ozone monitor to this community. The purpose of this is to measure the ozone in the ambient air using a technology that has been accepted as a Federal Equivalent Method. This monitor, as well as ozone data from the Bay Area Air Quality Management District (BAAQMD) ambient air monitoring systems, can be used to assess the overall quality of the data being presented to the community. The nearest BAAQMD monitors are located in Vallejo and San Rafael . It should be noted the actual location of BCAMP ozone monitor has been masked to respect the privacy of the host site.

BCAMP expresses its gratitude towards Phillips 66 for offering real-time data for methane, nitrous oxide, and ozone. It is noteworthy that no other refinery in the Bay Area currently offers such information for public scrutiny.

For additional information, here are some useful links:

Ozone

Rodeo North

26.8 PPB

Rodeo South

50.2 PPB

Since ozone is considered a regional air pollutant, the data from the Rodeo fence-line air monitoring system should track the BCAMP and BAAQMD air monitoring stations. The BCAMP air monitoring system is installed within the community of Rodeo and the BAAQMD air monitoring stations are located in the communities of Vallejo and San Rafael.

Methane

Rodeo North

2059.2 PPB

Rodeo South

2669.8 PPB

According to the EPA, data from fence-line systems should be considered suspect if the methane readings are below 1,720 parts-per-billion.

Nitrous Oxide

Rodeo North

297.4 PPB

Rodeo South

379.1 PPB

According to the EPA, data from fence-line systems should be considered suspect if the nitrous oxide readings are outside the range for 270 to 330 parts-per-billion.

What is Benicia Community Air Monitoring Program (BCAMP)?

BCAMP is a non-profit established for the benefit of the community to monitor ambient air quality in Benicia. BCAMP independently holds, operates, and maintains air monitoring equipment at a community-based monitoring station and provides a public access website. BCAMP's mission is to sample and measure local air in real time; report and archive raw data on the website; and provide education on health risks as related to air quality.

Who operates the BCAMP station?

BCAMP has contracted Argos Scientific to operate and maintain our monitoring station's equipment and website. Established in 2006, Argos is a recognized expert in air quality monitoring throughout the world. Currently, Argos currently operates fence line monitoring systems at several Bay Area refineries and also supports community monitoring systems in southern California, and contributes research on state-of-the-art advances in monitoring technologies, working with state-wide Air District regulators.
