EPA Announces Cleanup Plan for Quanta Resources Superfund Site in Edgewater, New Jersey
The U.S. Environmental Protection Agency has finalized a plan about containing and controlling soil and groundwater contamination at the Quanta Resources Superfund Site in Edgewater, New Jersey. This site is along the Hudson River. Soil and groundwater contamination originates from over 100 years of industrial activities. It includes arsenic, lead, polycyclic aromatic hydrocarbons, and volatile organic compounds. These pollutants can cause serious health issues, increasing cancer risks in some cases. Due to the complex contamination, the EPA divides the cleanup into two phases. The first phase focuses on the contaminated soil and groundwater, while the second phase will tackle contamination in the river. Today, the EPA announces the first phase of the long-term cleanup plan. A future cleanup plan will address river contamination.
Address the Contaminated Soil and ground water at the site
The plan to address the contaminated soil and groundwater was proposed in July 2010. This followed extensive research and analysis of the environmental issues. The Environmental Protection Agency (EPA) recognized the importance of community engagement and transparency in decision-making. They initiated a robust public participation campaign. To encourage involvement, the EPA held a public comment period that lasted over 60 days. Residents and stakeholders had the chance to voice their concerns and suggestions. Additionally, the agency conducted two public meetings. This provided a platform for dialogue and interaction among community members and experts.
In addition, the EPA also carefully reviewed input from over 70 interested individuals or parties. Thereby ensuring that diverse perspectives were considered. Especially in the development of the remediation strategy. This comprehensive approach not only aimed to restore the affected areas but also sought to foster trust and cooperation between the agency and the community, thereby paving the way for a healthier environment for future generations.
The site contains an estimated 150,000 cubic yards of contaminated soil requiring treatment to protect people that may come into contact with it. EPA will solidify and stabilize areas of soil contaminated with oily liquid and arsenic by turning them into leak-proof blocks underground. The process is also being done in several steps. It will begin with the clearing of vegetation and debris from the surface, and the removal of approximately the first four feet of the surface soil. This material was also sent off-site for disposal at a licensed facility. EPA will treat the toxic pollutants further underground by mixing the soil with cementing materials that will harden in place. The process is similar to making concrete. Clean material is also on top of these solid blocks.
Ground Water
Ground water from the site flows into the Hudson River. The EPA removes pollutants from the ground water. They also installed an underground barrier system to control ground water contamination. This system allows the ground water to flow through a special material. The material removes contaminants. The agency monitors the ground water barrier closely. They implement deed restrictions. These restrictions also limit the use of ground water from the site and any related activities. Throughout the cleanup, they conduct monitoring and testing. Further studies take place to carefully ensure the remedy’s effectiveness.
Some areas of soil beneath the buildings on a neighboring property. That address is 115 River Road and is also being contaminated by oily liquid. A liquod that poses potential risks to the environment and public health. Small businesses occupy these buildings, which serve as vital hubs for the local community, providing various services and products to residents. They are remaining in place for now as the contaminated material is managed carefully and under the supervision of environmental experts. The ongoing monitoring of the site aims to assess the extent of contamination and mitigate risks effectively. The EPA has decided that there is no immediate need to demolish the buildings, considering that the potential for safe management of the situation exists, while emphasizing the importance of ensuring the health and safety of those who work and visit the area.
Systems Being Put in Place
A system prevents potentially harmful vapors from contaminated soil and groundwater. It also stops these vapors from entering the buildings. This action serves as a precaution. Periodic indoor air testing at these buildings since 2002 shows no current exposure to vapors. Additionally, we install a barrier wall. This wall isolates pollutants underneath the buildings. Moreover, it keeps them from seeping into the Hudson River.
The solidification and stabilization method treats contaminants under the buildings. It mixes contaminated materials with binding agents. This process securely encapsulates harmful substances. Consequently, it prevents leaching into the environment. This approach ensures safety in the area. Additionally, it enhances the site’s structural integrity. During redevelopment, ongoing monitoring takes place. This monitoring assesses the treatment’s effectiveness. Stakeholders remain committed to environmental regulations. Furthermore, they incorporate sustainable practices into the redevelopment plan. Ultimately, the goal is to create a healthier environment for future residents. In addition, it aims to support businesses taking significant steps toward land reclamation. For more details, consult the method.
Sediment near the site on the Hudson River
Sediment near the site in the Hudson River also contains elevated levels of arsenic, lead, poly aromatic hydrocarbons, volatile organic compounds and oily liquids. EPA is completing separate studies of the Hudson River contamination that will lead to a second and final cleanup plan for the site.
The Quanta Site is the Ground Contamination Site
The Quanta site lies on River Road at the intersection of Gorge Road in Edgewater. It has a rich and complex history that dates back to the 1880s. Initially, it served as a coal tar facility. The site’s operations changed over the decades. By the 1970s, it became a “tank farm.” This facility stored waste oil for reprocessing.
This shift reflects growing awareness around waste management and environmental concerns. However, the state of New Jersey closed the facility in 1981. Authorities found hazardous waste oil in storage tanks. This oil contained polychlorinated biphenyls, known as PCBs. These substances harm human health and the environment.
Between 1985 and 1992, the EPA supervised emergency actions. They safely removed millions of gallons of waste oil, sludge, and contaminated water from tanks. Furthermore, they cleaned and dismantled the emptied storage tanks and piping to prevent further leakage. Afterward, sampling at the site revealed residual contamination. It remained in the soil, groundwater, and sediment. This contamination poses a long-term risk to human health and the environment.
Today, the once-polluted site transforms. It now features a thriving waterfront community with businesses, apartment buildings, and major roadways. This change showcases the resilience of urban landscapes. The site is also added to the federal Superfund list in September 2002. This designation highlights ongoing efforts to address environmental hazards. It also aims to restore the area for future generations.
