Long Island City (LIC) in Queens, New York, has long been known for its industrial prowess. From the late 19th century onward, LIC became a hub of manufacturing and production, contributing to New York City’s economic growth. However, this industrial boom came at a cost. The area’s factories and chemical plants left behind a legacy of toxic waste, including the hazardous chemical 1,4-dioxin. Known for its toxicity and persistence in the environment, 1,4-dioxin poses significant health risks to residents and challenges for environmental cleanup efforts. This blog explore LIC’s industrial history, the dangers of 1,4-dioxin, and the ongoing fight to address this toxic legacy.
What is 1,4-Dioxin?
1,4-Dioxin is a highly toxic chemical compound that is often produced as a byproduct of industrial processes, particularly in the manufacturing of herbicides and other chemicals. Unlike its more widely known cousin, dioxin, 1,4-dioxin is less well-known but equally dangerous. It is a persistent environmental pollutant, meaning it does not break down easily and can remain in the soil and water for long periods. Exposure to 1,4-dioxin can occur through ingestion, inhalation, or skin contact, leading to serious health risks. In LIC, the presence of 1,4-dioxin is a direct result of decades of industrial activity, making it a significant environmental concern.
The Industrial Development of Long Island City
Long Island City (LIC) in Queens, New York, has a rich industrial history that has left a lasting impact on its environment, particularly concerning the contamination of its water supply with 1,4-dioxane. This chemical, classified as a probable human carcinogen by the U.S. Environmental Protection Agency (EPA), poses significant health risks due to its persistence in the environment and potential for bioaccumulation.
Sources of 1,4-Dioxane Contamination in Long Island City
Long Island City (LIC) has a history of industrial activity that has left behind a lasting environmental issue: the contamination of its water and soil with 1,4-dioxane. This toxic chemical byproduct is primarily linked to improper waste disposal and chemical manufacturing from factories that operated in the area. These practices resulted in 1,4-dioxane seeping into the groundwater and surrounding land, which continues to affect the local environment today. While the area has made strides in addressing these contaminants, the legacy of industrial pollution remains a significant health risk.
The pie chart below highlights the primary sources of 1,4-dioxane contamination in LIC. Industrial waste disposal, chemical manufacturing, and leaky underground tanks are the most significant contributors, with stormwater runoff also playing a role in carrying the chemical into the water system. By understanding the breakdown of these sources, we can better grasp the challenges facing Long Island City and work toward more effective remediation efforts to protect public health and the environment.
Current Contamination Levels
Recent studies and reports have highlighted the ongoing presence of 1,4-dioxane in the groundwater of LIC. For instance, a 2023 report by the Citizens Campaign for the Environment (CCE) noted that 1,4-dioxane is an emerging contaminant of concern found in Long Island’s groundwater and drinking water. The report emphasized that while New York State has adopted stringent drinking water standards for 1,4-dioxane, water suppliers are still in the process of installing the necessary filtration systems to meet these standards.
Additionally, a 2024 article from the Nassau Suffolk Water Commissioners Association (NSWCA) discussed the challenges in regulating 1,4-dioxane, noting that while the EPA has listed it as a probable human carcinogen, there is currently no federal Maximum Contaminant Level (MCL) for 1,4-dioxane. The article highlighted that the New York State Department of Health (NYSDOH) regulates 1,4-dioxane as an Unspecified Organic Contaminant (UOC) with a blanket MCL of 50 parts per billion (ppb). However, the NYSDOH has proposed a recommended drinking water quality MCL of 1.0 ppb, which is under review.
The Environmental Impact of 1,4-Dioxin in LIC
The environmental impact of 1,4-dioxin in Long Island City is substantial. As a persistent organic pollutant, it has contaminated the soil and water in the area, posing long-term risks to the ecosystem and human health. In LIC, where industrial waste was frequently dumped or improperly stored, 1,4-dioxin has infiltrated the environment, leading to the contamination of groundwater and the surrounding land. The chemical’s persistence means that it remains in the environment for years, continuing to pose a threat long after the factories have closed. This contamination has significant implications for the health of local residents and the future development of the area.

Health Risks of 1,4-Dioxin Exposure
There are various nefarious side effects from 1,4-dioxin exposure. The chemical is extremely toxic and can lead to liver and kidney damage, reproductive and developmental defects and even cancer. The potential for exposure is increased in Long Island City by the contaminating the surrounding area (mainly the groundwater). Those living near contaminated water or soil can develop long-term health effects, such as a greater risk of cancer. It is a health risk from 1,4-dioxin that should be addressed in order to safeguard the health of LIC’s residents now and into the future.
Exposure to 1,4-dioxane has been linked to several health issues:
Liver and Kidney Damage: Studies have shown that high levels of 1,4-dioxane exposure can lead to severe liver and kidney effects, potentially resulting in organ failure.
Cancer Risk: The U.S. Environmental Protection Agency (EPA) classifies 1,4-dioxane as a probable human carcinogen, indicating a potential increased risk of cancer from exposure.
Reproductive and Developmental Effects: Long-term exposure may impair the immune system, the developing nervous system, the endocrine system, and reproductive functions.
Studies on 1,4-Dioxane in Long Island City
Research efforts are underway to assess the extent of 1,4-dioxane contamination in LIC and its health implications:
Yale Superfund Research Center Study: Researchers are conducting a cross-sectional study on Long Island to measure 1,4-dioxane levels in resident water supplies and blood samples. The study aims to monitor biological responses and identify markers of exposure.
Community Health Impact Assessment: The Citizens Campaign for the Environment (CCE) is collaborating with the Yale Superfund Research Center to understand the impacts of 1,4-dioxane contamination on Long Island residents. This partnership focuses on community education and participation in research studies.
Regulatory Challenges and Responses
It’s a very difficult regulatory task to deal with 1,4-dioxin contamination in Long Island City. Environmental agencies have acknowledged that the chemical poses risks, but cleanup plans and safe exposure limits are hard to achieve because the chemical is so long-lived and widespread. In LIC, the complexity of contamination has meant remediation has been slow and expensive. Regulators such as the EPA have enacted monitoring programmes and clean-up programs, but the work has been slow. Coordinating between the different levels of government, and private industry that is polluting it, is essential to the effectiveness of regulatory action.
EPA Risk Evaluation: The EPA has identified health risks associated with 1,4-dioxane, including liver toxicity and cancer from inhalation or dermal exposures, as well as from ingestion of drinking water.
State-Level Initiatives: New York State has established a drinking water standard for 1,4-dioxane, setting the maximum contaminant level at 1 part per billion. This regulation aims to protect public health by limiting exposure to this harmful chemical.
