The Quanta Resources Corporation site is located in the Borough of Edgewater, Bergen County, New Jersey. Starting in the late 1800s, coal tar, paving and roofing materials were made at the site by various companies. Quanta Resources operated an oil processing facility there from 1974 to 1981, when the New Jersey Department of Environmental Protection (NJDEP) closed the site after discovering large quantities of polychlorinated biphenyl (PCB)-laden oil in storage tanks.

The site is being addressed in two operable units. Operable Unit 1 (OU1) addresses the land and groundwater and Operable Unit 2 (OU2) addresses the sediments and the river.

What Has Been Done to Clean Up the Site?

From approximately 1876 to 1967, coal tar, paving and roofing materials were manufactured on site. Allied Chemical Corporation’s Asphalt Division (now Honeywell) took over operations in 1930. In 1974, Allied Chemical sold the property to Mr. James Frola and Mr. Albert Von Dohln. In 1977, Mr. Frola and Mr. Von Dohln leased the property to E.R.P. Corporation for the storage and recycling of oil. Shortly thereafter, E.R.P. assigned its lease to Edgewater Terminals, Incorporated. Quanta Resources Corporation began operating at the property after a transfer of the lease from Edgewater Terminals. From 1979 to 1981, Quanta Resources operated a waste oil processing facility. The site had 61 aboveground storage tanks with a total capacity of over 9 million gallons, along with an unknown number of underground storage tanks and numerous underground pipes. These tanks were used to store oil, tar, asphalt, sludge, process water and other unknown liquids.

In July 1981, NJDEP forced the closing of the Quanta Resources facility when sampling found that storage tanks contained large quantities of oil with PCBs concentrations as high as 260 parts per million. After initial actions to protect human health and the environment, and additional site investigations, EPA placed the site on the Superfund program’s National Priorities List in September 2002.

In 1984, the state of New Jersey asked EPA to help address the PCBs and other hazardous liquid wastes on the now-abandoned facility through the Emergency Response program. Between 1984 and 1988, EPA directed and provided oversight of several cleanup actions performed by parties responsible for the contamination. Approximately 1.35 million gallons of PCB-contaminated oil were removed for off-site treatment. Over 1.5 million gallons of coal tar were removed from storage tanks and recycled. Over 60 aboveground storage tanks and 10 underground storage tanks, as well as numerous underground pipes, were removed.

In 1996, EPA and one PRP, the successor to Barrett Manufacturing Company, AlliedSignal (formerly Allied Chemical Company, now Honeywell), entered into an AOC under EPA's removal authority to improve site security, further investigate the extent of site problems, and develop further response actions for the site. A second AOC was signed in 1998 designating steps to investigate and address the ongoing coal tar sheens in the mudflats of the Hudson River in front of the site. The studies performed under these AOCs, along with an ecological risk assessment of Hudson River sediments performed by the EPA, finally led to the proposal of the site to the NPL. On January 11, 2001, EPA proposed inclusion of the site on the NPL, and on September 9, 2002, EPA placed the site on the NPL.

Field work for the remedial investigation began in summer 2005 and was completed in spring 2009. A draft Remedial Investigation report was submitted in August 2009. The Feasibility Study was initiated in 2009 and was completed in summer 2010. A Proposed Plan was issued by EPA on July 21, 2010. The public comment period began on July 21, 2010 and ended on November 18, 2010, after several requests for an extension from the community. A Record of Decision was issued in September 2011.

In May 2017, the cleanup of the site began on the west side of River Road on the Block 93 parcel, and took about 6 weeks to complete. The cleanup activities then moved to the main Quanta site located between River Road and the Hudson River. In late May 2018, soil solidification work at the site was paused for the summer to allow the owner of the land parcel of 115 River Road to demolish the building. Though not a part of the remedial action, removal of this building will allow for remediation of contaminated soils under the foundation. Cleanup of the land portion (OU1) of the main site is estimated to take 24 months. As of October 2018, approximately 50% of the soil solidification work on OU1 is complete.

What Is the Current Site Status?

 EPA is addressing site contamination in Operable Unit 1 (OU1) in several ways. To address contaminated source areas in the soil – primarily zones of NAPL coal tar and arsenic – EPA is using in-situ (meaning in place) solidification and stabilization (ISS); non-aqueous phase liquid (NAPL) recovery wells to collect flowable product; and capping of both the treated source areas and areas where contaminated soils are present. To address the groundwater, a subaqueous reactive barrier will be installed in conjunction with the future Operable Unit 2 (OU2) remedy to address contaminated sediments in the Hudson River. The barrier will function as a filter to remove contaminants from groundwater.

NAPL recovery wells were installed in 2015 and are being monitored quarterly. ISS of the NAPL zones started in summer of 2017 and is expected to take approximately two years to complete. Treatment of an area containing high concentrations of arsenic is being evaluated under a separate schedule.

Portions of the NAPL are under buildings at a neighboring property, 115 River Road, and also under River Road, a major thoroughfare. NAPL beneath the buildings will be treated via ISS after the buildings are demolished. Treatment of the NAPL beneath River Road will be coordinated with Bergen County, the owner of  the road.

The site is currently fenced to restrict access. An air monitoring plan is being implemented to protect the workers performing the cleanup and the surrounding community. A network of stationary and mobile air monitors record levels of dust and volatile organic compounds.

Absorbent booms are in place in the river to intercept surface water contamination until the implementation of the OU2 remedy. The booms are maintained regularly and replaced when necessary.

Contamination in the sediments of the Hudson River, OU2, is under investigation.  Phase one of the remedial investigation was completed in 2014.  Review of the collected information indicated the need for additional data gathering.  This work has been on going since 2014 and the last phase was completed in 2018.  Currently, the data is being used to develop the feasibility study o evaluate appropriate remedial technologies for addressing the contamination in the sediments and surface water of the Hudson River.  In addition, bench-scale treatability studies are also being conducted to evaluate the ISS treatement technology for this operable unit.

Sampling and Monitoring

Air and Dust Monitoring During Demolition of the 115 River Road building

On May 18, 2018, soil solidification work at the Quanta site was suspended in preparation for the demolition of 115 River Road. All activities that could potentially disturb contaminated soil at the site ended June 27. Since June 21, air samples at all five residential properties (City Place, The Metropolitan, The Promenade, iPark, and Independence Harbor) have consistently registered as non-detect for naphthalene and other site-related contaminants.

Based on the data from Independence Harbor, The Metropolitan, and The Promenade, sampling equipment was removed from these three locations on July 9.  Air sampling and laboratory analysis for naphthalene and other constituents continue at City Place and iPark.

The air monitoring network will be restored when soil solidification work resumes in early 2019.

Air Monitoring

The air quality monitoring program at the Quanta site addresses odors, dust prevention, and incorporates best practices to meet air quality health standards. The air monitoring network includes both on-site and perimeter monitoring, and air monitors at residential properties adjacent to the site: Independence Harbor, IPark, City Place, The Metropolitan, and The Promenade. A portable weather station is located on-site to monitor wind speed and direction.

Real-time monitors at the perimeter of the site measure dust and total volatile organic compounds in air as work is occurring. Sensors alert at a low “warning level” to allow action to be taken before dust or site-related contaminants reach action levels. A full-time air quality specialist monitors the system and is authorized to stop work if necessary. These results are posted within about one business day.

Air samples are collected for off-site laboratory analysis of 17 volatile/semi-volatile organic compounds that are present in the soil at the Quanta site. The results are compared with risk screening levels and used to evaluate and adjust emission control activities, if necessary, and to assess potential human health risks. Aside from naphthalene, low concentrations of the other 16 chemicals were detected at levels consistent with air quality in urban areas and do not appear to be associated with work at the Quanta site.
