Air quality health advisories
The U.S. Air Quality Index (AQI) is used by the New York State Department of Environmental Conservation (DEC) and the U.S. Environmental Protection Agency (EPA) to communicate daily air quality levels. Color-coded categories inform citizens about the air quality in their area, groups of people who may be affected, and actions they can take to reduce their exposure to air pollution. Sensitive groups include children and teens, the elderly, pregnant people, those with lung or heart conditions, asthmatics, those who exercise or work outdoors, and those in disadvantaged communities.
During high-heat air pollution events, sensitive groups are urged to seek indoor locations with air conditioning or go to a cooling center. The DEC provides daily AQI forecasts for two major pollutants, ground-level ozone and particulate matter, based on the EPA's National Ambient Air Quality Standards. The AQI is an 8-hour average for ozone and a 24-hour average for particulate matter.
In the case of Long Island City, an Air Quality Health Advisory was issued for the New York City Metro and Long Island regions due to the potential impact of smoke from wildfires in New Jersey. The advisory was in effect from 12 a.m. through 11:59 p.m. on April 24, 2025. Similarly, an update to the Air Quality Health Advisory was issued for Long Island, New York City Metro, and the Lower Hudson Valley regions on June 12, 2025, due to the impact of smoke from wildfires in Canada. The advisory on fine particulate matter, including ozone, was in effect from 11 a.m. to 11:59 p.m.
To reduce air pollution, the DEC recommends using public transportation, carpooling, or riding a bike instead of driving. Additionally, conserving fuel, reducing exhaust emissions, and using fans to circulate air can help improve air quality.

Nitrogen pollution
The Long Island Sound Study (LISS) has identified nitrogen pollution as a core issue, and efforts to reduce nitrogen levels have been ongoing. The Connecticut Department of Energy and Environmental Protection (CT DEEP) and the New York State Department of Environmental Conservation (NYS DEC) have played pivotal roles in addressing this problem. In 2001, the U.S. Environmental Protection Agency (EPA) approved a mandate for a 58.5% reduction in human-generated nitrogen, demonstrating the urgency of the situation.
The Long Island Nitrogen Action Plan (LINAP) is a multi-year initiative that aims to significantly reduce nitrogen levels through various approaches. These include fertilizer management, water reuse, and nutrient bioextraction. The plan encourages individuals to take the "Reduce Nitrogen Pledge," which involves committing to ten simple actions in their daily lives to reduce nitrogen pollution. LINAP has now been integrated into the Long Island Watershed Program, which takes a holistic, watershed-level approach to safeguarding the island's water resources.
Despite these efforts, nitrogen pollution remains a challenging issue. The complex interplay of human activity, chemistry, and local meteorology influences nitrogen dynamics in the region. Additionally, the impact of urban emissions, pollution transport, and meteorology on nitrogen dioxide (NO2) pollution near highly populated coasts requires further characterization. To address this, researchers have integrated measurements from boats, ground-based networks, aircraft, and satellites to better understand and manage nitrogen pollution in the New York metropolitan area, including Long Island City.

Ozone and PM2.5
Ozone, on the other hand, is a colorless gas that can produce hazy skies and reduce visibility in high concentrations. It is a major component of photochemical smog and is formed when sunlight reacts with nitrogen oxides and volatile organic compounds from automobile exhaust and industrial emissions. Ozone is considered one of the most dangerous gaseous pollutants, and high levels of ozone in the air can be harmful to human health, particularly for individuals with cardiovascular and respiratory diseases, young children, and the elderly.
To address the issue of ozone and PM2.5 pollution, the New York State Department of Environmental Conservation (NYSDEC) and the Department of Health (DOH) issue Air Quality Health Advisories when levels of these pollutants are expected to exceed an Air Quality Index (AQI) value of 100. During periods of high pollution, vulnerable individuals are advised to limit their outdoor physical activity and stay indoors to reduce exposure. Additionally, the use of public transportation, carpooling, and reducing vehicle trips can help decrease automobile emissions, which contribute significantly to ozone and PM2.5 pollution.
While annual averages for particulate pollution in New York City meet most guidelines, the city continues to struggle with ozone pollution. A 2011 analysis attributed approximately 10% of hospital visits for asthma in the city to ozone pollution. The COVID-19 lockdown in March 2020 also provided a unique perspective on the impact of human activity on air quality. During this period, New York observed a 25% reduction in fine particle pollution (PM2.5) compared to the same time in 2019, with a significant increase in "good" air quality days.

Impact of wildfires
In March 2025, Long Island City was affected by a series of wildfires that burned over 400 acres of land in Suffolk County. The fires were fueled by downed trees and fanned by winds of up to 35 miles per hour. Governor Kathy Hochul declared a state of emergency and deployed ground and air support, including eight helicopters, for immediate fire suppression. The New York State Department of Environmental Conservation (DEC) also implemented a burn ban for Long Island, New York City, and parts of the Hudson Valley to prevent further wildfires.
The impact of the wildfires on Long Island City was significant. The fires disrupted the lives of residents and caused environmental damage. Here are some of the key impacts:
- Evacuations and Displacement: The wildfires prompted evacuations east of New York City, displacing an unknown number of residents from their homes.
- Air Quality Degradation: The fires released plumes of ashy gray smoke that rose high into the atmosphere and could be seen from Connecticut. This smoke likely contributed to poor air quality in Long Island City, potentially causing respiratory issues and throat irritation, especially in sensitive groups.
- Ecological Damage: The wildfires burned hundreds of acres of land, including the Suffolk County parkland and the Westhampton Dwarf Pine Plains Pine Barrens State Forest. This destruction of habitats and ecosystems led to the loss of biodiversity and ecological imbalances.
- Economic Losses: While the exact economic impact is unknown, wildfires can result in significant financial losses for affected communities. This includes damage to property, infrastructure, and natural resources, as well as the costs of firefighting efforts and emergency responses.
- Firefighting Challenges: The strong winds and dry conditions made firefighting extremely challenging. The fire spread quickly, and firefighters had to work tirelessly to contain and suppress the flames. The high winds also raised concerns about the potential for the fires to reignite or spread to new areas.

Water quality
Long Island's water comes from a variety of sources, including lakes, wells, and groundwater aquifers. The quality of the water varies greatly across the island, with some areas having TDS levels of 100 to 250 PPM. The water in Long Island is more vulnerable to contamination due to its source, and it has been found to contain harmful levels of 1-4-dioxane, PFOS, PFOA, and PFAS. These contaminants are resistant to biodegradation and can cause adverse health effects, including irritation of the throat, eyes, and nose, as well as more severe issues like liver tissue damage, cholesterol changes, fetus developmental effects, and cancer.
The presence of these contaminants in the water supply has raised concerns among residents, with many opting for water filtration systems to ensure their drinking water is safe. Environmental groups are urging the New York state Department of Health to strengthen regulations, as more than 600,000 Long Islanders are drinking water that exceeds current standards. The Citizens Campaign for the Environment has also played an active role in raising awareness about the high levels of PFAS chemicals detected in the water.
Long Island's industrial history, particularly its manufacturing past, has significantly contributed to the water quality issues the region is facing today. Contaminants like 1,4-dioxane, a probable human carcinogen, have been detected in the groundwater, posing risks to both ecosystems and human health. Efforts to address this issue include regular testing and monitoring of water sources, infrastructure upgrades, and collaboration between local authorities, researchers, and community organizations.
Additionally, nitrogen pollution from onsite wastewater and septic systems has been identified as a major concern for water quality in Long Island. Excessive nitrogen levels contribute to toxic algae blooms and oxygen-depleted dead zones, which have detrimental effects on marine habitats, fisheries, and coastal wetlands. To mitigate these issues, policies focusing on upgrading septic systems and reducing nitrogen loading have been proposed.
Oyster farms have also been suggested as a natural solution to combat nitrogen pollution, as they can filter large volumes of water, improving water quality. While Long Island faces significant water quality challenges, collaborative efforts and proactive solutions are driving progress toward ensuring safe drinking water and protecting the region's fragile ecosystems.
