Everyday Polluters: New Mexico's Unseen Crisis

New Mexico is known for its captivating landscapes, art, and cultural heritage. However, it also faces significant pollution problems that threaten the health of its residents and natural ecosystems. Everyday activities and industries contribute to the state's air, water, and soil pollution. For instance, vehicles, wildfires, industrial emissions, mining, and oil and gas operations release various pollutants, including methane, volatile organic compounds (VOCs), black carbon, methane, carbon monoxide, and fine particles. These pollutants have detrimental effects on human health, leading to respiratory issues, cancer, and other adverse outcomes. New Mexico's beautiful landscapes are at risk, and addressing pollution is crucial for the well-being of its residents and the environment.

Oil and gas facilities

There are over 62,000 oil and gas facilities in New Mexico, and these contribute to air pollution through the release of various pollutants. These include volatile organic compounds (VOCs), which contribute to the formation of ground-level ozone (smog), benzene, a known carcinogen, and hydrogen sulfide, which has a similar toxicity level to carbon monoxide. The facilities also emit methane, a potent greenhouse gas that is extremely harmful when inhaled over long periods or in large quantities. According to the Environmental Defense Fund, New Mexico's oil and gas companies emit over 1.1 million metric tons of methane annually, approximately five times more than EPA data suggests. This has the same near-term climate impact as 25 coal-fired power plants.

The pollution from these facilities has adverse health effects on nearby residents, particularly Indigenous people, who are disproportionately impacted. The American Lung Association has given failing grades to the four major oil- and gas-producing counties in New Mexico due to high ozone days, indicating that people living in these areas are exposed to asthma-exacerbating air pollution. The New Mexico Environment Department has confirmed that oil and gas activities impact the health of nearby residents, with reported symptoms including respiratory issues, eye, nose, and throat irritation, headaches, nausea, dizziness, sleep problems, and fatigue.

The San Juan Basin, a crude oil and natural gas-rich region in northwestern New Mexico, is an example of an area where Native American residents are disproportionately affected by the oil and gas industry. According to Robyn Jackson, interim executive director of Diné CARE, the San Juan Basin is dealing with the "historical legacy of resource extraction and pollution," and the impacts of these activities on the environment have affected future generations' connections to the land and cultural traditions.

The economic toll of methane waste due to oil and gas operations in New Mexico is also significant. The state is estimated to waste $271 million worth of natural gas annually and lose out on an additional $43 million in tax and royalty revenue, according to the Environmental Defense Fund.

Mining

The issue of mining pollution is not unique to New Mexico and affects many other states, including Montana, California, Colorado, and Oklahoma. In some cases, the pollution has persisted for decades, even after the sites have been included in the federal Superfund cleanup program for the nation's most hazardous locations. The Superfund program has faced funding cuts, hindering the cleanup efforts.

In New Mexico, the Copper Rule, a set of regulations governing water pollution by copper mines, has been challenged by various groups. They argue that the rule allows for the intentional pollution of groundwater rather than preventing it, which could set a dangerous precedent for other industries. The rule permits mining companies to contain and treat polluted groundwater at their sites indefinitely, but there is little assurance that these companies will be around for the long-term cleanup.

The scope of the problem is immense, with more than 50 million gallons of contaminated wastewater flowing daily from mining sites, impacting nearby groundwater, rivers, and ponds. The pollution contains harmful substances such as arsenic, lead, zinc, and other toxic metals. The treatment and cleanup of this pollution are costly and may need to continue indefinitely, posing a significant challenge to ensuring clean water sources for communities affected by mining operations.

Vehicle emissions

Vehicles, particularly heavy-duty diesel-run trucks, release large amounts of pollution and particulate matter into the atmosphere. The particulate matter includes microscopic rubber particles from worn-down tire treads, which can have adverse health effects on residents. Diesel fuel is a fossil fuel, and its combustion releases pollutants such as fine particles, volatile organic compounds (VOCs), mercury, sulfur dioxide (SO2), and nitrogen oxides (NOx). These emissions contribute to ground-level ozone (smog) formation, which is a harmful air pollutant and a concern for public health, particularly for those with respiratory issues.

In addition to diesel-run vehicles, the state's proximity to oil and gas facilities and the emissions from these contribute to the air pollution experienced by residents. Oil and gas operations release hazardous pollutants, including methane, benzene, toluene, and hydrogen sulfide, which have severe health impacts, including respiratory problems, eye and throat irritation, and increased risks of cancer.

New Mexico's heavy reliance on fossil fuels for energy production and transportation contributes to its air pollution levels. The state's industrial processes, such as emissions from factories, power plants, and fertilizers, also play a role in the overall pollution levels. While there have been changes in emission standards, many industries still depend on fossil fuels, exacerbating the pollution problem.

To address the issue of vehicle emissions and improve air quality, New Mexico needs to transition to cleaner energy sources and implement stricter emission regulations for vehicles, particularly heavy-duty trucks. Additionally, promoting public transportation, electric vehicles, and renewable energy sources can help reduce vehicle emissions and improve the health and well-being of New Mexico's residents and natural ecosystems.

Wildfires

New Mexico is susceptible to wildfires, which are a significant contributor to air pollution in the state. Wildfires can occur within New Mexico or in adjacent states, and strong winds often carry large clouds of smoke and pollutants over neighbouring areas. The smoke and pollution clouds from wildfires contain a high amount of harmful chemicals, which present a notable health risk to residents.

The state's natural beauty and desert landscapes are under threat from the increasing frequency and intensity of wildfires. Climate change is leading to longer and more severe wildfire seasons in New Mexico, which endanger the health and property of residents. The Buzzard Fire in the Gila National Forest in the summer of 2018, for example, caused elevated particulate pollution in Albuquerque, with health experts advising residents to remain indoors.

The state's decreasing snowpack levels, which have been declining since the 1950s, pose a threat to major water sources such as the Rio Grande, Pecos, and San Juan rivers, as well as drinking water supplies. The combination of high temperatures and low precipitation associated with climate change makes the region more susceptible to wildfires.

The impact of wildfires is not limited to air quality degradation; they also contribute to water pollution. Discharges of heated water from power plants, for instance, cause thermal pollution, which affects over half of New Mexico's rivers. The state's natural ecosystems are also at risk, as metal pollution and nutrient pollution harm aquatic life.

Furthermore, wildfires release methane and other pollutants into the atmosphere. Lax regulations and insufficient monitoring resources have previously allowed the emission of these harmful substances without consequence. The Permian and San Juan Basins, two of the largest methane sources in the nation, contribute significantly to this issue.

Fertilizer and animal waste

Fertilizers and animal waste are significant contributors to pollution in New Mexico, particularly regarding water quality. While fertilizers provide essential nutrients like nitrogen and phosphorus for crop growth, they can also negatively impact the environment if not properly managed. Improper application of fertilizers can lead to nutrient losses, with excess nitrogen and phosphorus ending up in nearby waterways. This, in turn, can cause eutrophication, leading to "dead zones" where fish and other aquatic life cannot survive. Additionally, high levels of nitrogen in the form of compounds like ammonia and nitrogen oxides can be harmful to aquatic ecosystems and contribute to greenhouse gas emissions.

Animal waste, particularly from livestock operations, is another source of pollution. When animals have unrestricted access to streams, rivers, and lakes, their waste introduces excess nitrogen and phosphorus into the water. This contributes to eutrophication and can result in harmful algal blooms (HABs), which produce toxins harmful to both wildlife and humans. To address this issue, farmers and ranchers can implement measures such as fencing off water bodies to control livestock access and prevent nutrient runoff.

The impact of fertilizers and animal waste on water quality is not limited to New Mexico but is a widespread issue, especially in urban areas. Research has shown that lawn fertilizers and pet waste are major sources of nitrogen and phosphorus pollution in urban watersheds. The dense infrastructure of streets and storm drains in urban areas facilitates the transport of these pollutants into surface waters, contributing to eutrophication and water quality degradation.

To mitigate the environmental impact of fertilizers and animal waste, proper nutrient management techniques are essential. This includes applying fertilizers in the correct amounts, at the appropriate times of the year, and using suitable methods. Additionally, farmers can engage in watershed efforts, collaborating with various stakeholders to reduce nutrient pollution in water and air. By adopting these practices, it is possible to minimize the negative effects of fertilizers and animal waste on the environment and protect the health of ecosystems and human communities that depend on clean water.

Overall, while fertilizers and animal waste are necessary for agricultural and landscaping practices, their improper use and mismanagement contribute to pollution in New Mexico and beyond. By implementing best management practices and adopting a holistic approach to nutrient management, it is possible to reduce the environmental impact and improve the sustainability of these everyday activities.
