EPA Proposes Expanded Cleanup for Old Pesticide Plant in Vineland, N.J.

(New York, N.Y. – July 22, 2016) The U.S. Environmental Protection Agency (EPA) has proposed modifications to its plan to clean up contaminated exposed sediments in the Maurice River and Blackwater Branch at the Vineland Chemical Company Superfund site in Vineland, N.J. As a result of previous operations by the chemical company at the site, the groundwater, soil and sediment are contaminated with arsenic. Arsenic is known to cause cancer, as well as many other serious health problems. The EPA performed dredging, excavation and disposal of arsenic-contaminated sediments at the site according to its original cleanup plan. The EPA proposes to modify the plan by adding treatment technologies to address areas in the Blackwater Branch that became re-contaminated with arsenic since those activities were completed.

The EPA does not believe the city’s drinking water has been impacted by the site. The EPA monitors the drinking water supply regularly to ensure the drinking water meets drinking water standards.

“The Vineland Chemical Company contaminated this site with arsenic from its production of pesticides,” said EPA Regional Administrator Judith Enck. “After decades of work by the EPA, a significant amount of the toxics have been removed. The EPA’s expanded work in Vineland will protect people’s health and the environment.”

The EPA will hold a public meeting on August 8, 2016 to explain the proposed plan and hear from the public. The meeting will be held at 6:30 p.m. at Vineland Town Hall – City Council Chambers, 640 E. Wood Street. Comments will be accepted until August 22, 2016.

The Vineland Chemical Co., Inc. site is centrally located at 1405 North Mill Road in Vineland, N.J. Arsenic-based herbicides were manufactured at a facility located at the 26-acre area from 1949 to 1994. Due to the company’s poor handling, storage and disposal of byproduct arsenic salts, soil, groundwater and the nearby Blackwater Branch, Maurice River and Union Lake have been contaminated by arsenic from the site.

The EPA has addressed the cleanup of the Vineland site in two stages: an immediate action, and four long-term cleanup phases focusing on controlling the source of the contamination, reducing the spread of the contamination, and cleaning up the marsh, river and lake sediments. 

In 1992 and 1993, the EPA fenced off the contaminated areas, removed hazardous chemicals stored on the site, and boarded up abandoned buildings.  By 2004, the EPA demolished all abandoned buildings on the site. To address the arsenic-contaminated soil, the EPA constructed a soil washing facility. To address contaminated groundwater, the EPA constructed a system to pump out and treat approximately two million gallons a day of contaminated groundwater. To address contaminated sediments in the Blackwater Branch and Maurice River, the EPA excavated and treated sediments in the soil washing facility.  After backfilling the area with clean soil, the stream channel and floodplain were restored.  The EPA continues to monitor the Maurice River. To cleanup Union Lake, the EPA plans to lower the water level, excavate and treat contaminated materials, then return the cleaned material to the lake.

To address the contaminated groundwater, in 1989, the EPA constructed a groundwater pump and treat system to prevent the arsenic contaminated groundwater from spreading into the Blackwater Branch. After the excavation and restoration of sediment of the Blackwater Branch was completed in 2012, the EPA found that even with the pump and treat system in place, exposed sediment and soil of the Blackwater Branch floodplain became re-contaminated with high levels of arsenic.

On order to address the exposed sediment and soil of the Blackwater Branch, the EPA is proposing to amend the cleanup by treating the arsenic in the groundwater in order to prevent recontamination of the exposed sediment. For instance, the EPA can use a technology called air sparging to reduce the contamination in the groundwater.  Oxygen injected into the ground through air sparging reacts with arsenic, making it immobile and insoluble. The specific treatment will be selected after the EPA further studies the conditions in localized areas to gauge the effectiveness.

The EPA may require excavation of “hot spots” to remove remaining contaminated exposed sediment or soil in the Blackwater Branch floodplain. Throughout the cleanup, monitoring, testing and further studies will be conducted to ensure the effectiveness of the remedy and protection of the environment. The cleanup under this plan is estimated to cost $15 million.

The Superfund program operates on the principle that polluters should pay for the cleanups, rather than passing the costs to taxpayers. The EPA searches for parties legally responsible for the contamination at sites that are placed on the Superfund list and it seeks to hold those parties accountable for the costs of investigations and cleanups. Potentially responsible parties have funded remedial work at the Vineland site. Other work has been federally funded with taxpayer dollars.
