California's Imperial Valley, an agricultural community near the Mexico border, is known for its high asthma rates and high levels of air pollution. The region has been labelled a non-attainment area under the federal Clean Air Act, meaning it does not meet the standards for healthy air quality. The air pollution in Imperial Valley has been attributed to various factors, including agricultural burning, emissions from factories, and the drying of the nearby Salton Sea, which releases toxic dust into the atmosphere. The area's proximity to the Mexican city of Mexicali, with a population of over 1 million people, has also been a contributing factor, as their air pollution rules are not as stringently enforced. These factors have led to Imperial Valley receiving a failing grade for air quality from the American Lung Association, with residents experiencing health issues such as asthma and other respiratory illnesses.

What You'll Learn
Imperial County's proximity to the Mexican city of Mexicali
Imperial County, California, is bordered to the south by the Mexican city of Mexicali. Mexicali is a large metropolis with a population of over 1 million people. The proximity of Imperial County to Mexicali is a significant factor contributing to the air pollution in the Imperial Valley.
The two regions share the same air, and emissions from Mexicali's industrial areas have a direct impact on the air quality in Imperial County. While Mexicali does have air pollution rules and regulations in place, they are not enforced as stringently as Imperial County would like. This has led to concerns about the air quality in the region, as the pollution from Mexicali contributes to the already high levels of air pollution in Imperial County.
The environmental justice group Comite Civico Del Valle, led by Luis Olmedo, has been advocating for better air quality in Imperial County. They have described the county's unhealthy air patterns as "the poster child of what the climate crisis looks like." The group has also raised concerns about the lax enforcement of air pollution rules in Mexicali, stating that while they have good rules, they are not enforced strictly enough.
The impact of Mexicali's emissions on Imperial County's air quality is significant. In addition to the industrial pollution from Mexicali, Imperial County also faces air pollution from other sources, including highway traffic, farming, and livestock operations. The combination of these pollution sources has led to high levels of air pollution in the region, with one in five children suffering from asthma, which is double the state rate.
The air pollution in Imperial County has been a persistent issue, with the region failing to attain federal standards for ozone pollution under the Clean Air Act for more than a decade. Efforts to improve air quality and reduce pollution sources in Mexicali are crucial to mitigating the air quality issues in Imperial County.

Agricultural burning
The Imperial County Air Pollution Control District requires authorisation for all burning activities in the county. Despite this, agricultural burning remains a persistent issue, with smoke and pollutants affecting the health of residents. The valley has been labelled a “non-attainment area” under the federal Clean Air Act, indicating that it does not meet the air quality standards set by the law.
The California Air Resources Board and local agencies are working to address the issue by considering stricter rules for agricultural burning and collaborating with Mexico to reduce pollution from factories and unpaved roads. However, the effects of agricultural burning continue to be felt by the residents of Imperial Valley, with high rates of asthma and other respiratory issues.
The impact of agricultural burning is not limited to the immediate area, as evidence suggests that the toxic particles from these burns have travelled as far as San Diego and Los Angeles. This highlights the far-reaching consequences of agricultural burning and the urgency of implementing effective measures to mitigate its impact on air quality and public health.

The drying Salton Sea
The Salton Sea is a shallow, landlocked, highly saline lake in California's Imperial and Riverside counties. It is the state's largest lake and was formed in 1905 when an irrigation canal gate failed, allowing the Colorado River to flood into the Salton Sink.
For almost a century, the Salton Sea was primarily fed by agricultural runoff from nearby farms. However, in recent years, the lake has been shrinking due to reduced inflows, climate change, and more efficient water use by farmers. As the lake bed becomes exposed, toxic dust is sent into nearby communities, causing air pollution and respiratory issues for residents.
The drying of the Salton Sea has had a disproportionate impact on disadvantaged communities in the region, particularly those with high Latino populations. These communities are already facing environmental injustices, including high rates of asthma and other respiratory illnesses. The dust from the lake bed contains pesticides and other chemicals, further worsening the air quality.
In an attempt to mitigate the impacts of the drying Salton Sea, various restoration projects have been undertaken, including habitat restoration and dust suppression initiatives. However, the lake continues to shrink, and the exposed lake bed continues to send toxic dust into the surrounding communities.
The state of California has recognized the urgency of the situation and has committed funding for air-quality management projects. Efforts are also being made to increase water flow to the sea and reduce dust and dust-borne toxins. However, finding a balance between conserving water and minimizing the impacts on the Salton Sea has proven challenging.

Emissions from factories
Imperial County, California, is an agricultural community near the Mexico border with a majority-Latino population and some of the worst air pollution in the country. The air pollution in the region is influenced by various factors, including emissions from factories, which we will explore in more detail.
The factories in Imperial Valley emit a range of pollutants through their production processes and operations. For example, chemical plants may release toxic chemicals and VOCs, while manufacturing facilities may emit particulate matter and hazardous air pollutants. Additionally, factories that use fossil fuels for energy generation or production processes may release nitrogen oxides (NOx) and sulphur dioxide (SO2) into the atmosphere, which contribute to the formation of acid rain and the creation of particulate matter through chemical reactions in the atmosphere.
The impact of factory emissions on air quality in Imperial Valley is significant. The pollutants released by these facilities can have both short-term and long-term effects on human health and the environment. For example, particulate matter and ozone can irritate the respiratory system, exacerbating asthma and other respiratory conditions. Additionally, VOCs and toxic chemicals released by factories can have adverse effects on human health, including respiratory issues, skin irritation, and in some cases, more severe health problems such as certain types of cancer.
Furthermore, the emissions from factories in Imperial Valley can contribute to climate change. For instance, NOx emissions from factories can also act as a greenhouse gas, contributing to the warming of the planet. Additionally, some VOCs released by factories, such as methane, are also potent greenhouse gases. The climate crisis further exacerbates air pollution, as warmer temperatures increase the formation of ground-level ozone and can intensify the effects of certain pollutants.
It is important to note that the impact of factory emissions on air quality in Imperial Valley is not limited to the immediate vicinity of these facilities. Prevailing wind patterns can carry pollutants over long distances, affecting nearby communities and even neighbouring regions. This is particularly relevant for Imperial County, as it shares its air with the South Coast Air Quality Management District to the north and the Mexican city of Mexicali to its south. Therefore, the emissions from factories in Imperial Valley have far-reaching consequences, contributing to air pollution across a broader geographic area.

Vehicle emissions
The mix of dust and vehicle emissions near communities in Imperial Valley exacerbates the air pollution problem. The region's proximity to the Salton Sea, which is drying up due to drought, also impacts air quality as toxic dust from the lake bed is blown into the valley. This dust contains agricultural runoff filled with fertilizers and other pollutants, creating a "climate catastrophe" according to Luis Olmedo, executive director of the environmental justice group Comite Civico Del Valle.
To improve air quality in Imperial Valley, there have been calls for more stringent enforcement of air pollution control policies, particularly in neighbouring Mexicali, Mexico. Efforts are also being made to reduce emissions from factories and unpaved roads, implement more regular smog checks, and impose stricter rules for agricultural burning.
