As a result of past industrial usage, there are a number of waste management areas, as well as areas of impacted soil and groundwater at the site. Over the past three decades, NJDEP and USEPA issued multiple Administrative Consent Orders (ACOs) and Records of Decision (RODs) for the investigation and remediation of the site. While significant progress has been made, investigations, engineering, design and active remediation are ongoing at the site.
Information regarding ongoing site monitoring and interim projects can be found here and on the Ongoing Efforts page. A summary of ongoing activities and achievements is provided in USEPA’s Summer 2016 Update
Wyeth Holdings LLC (WH), formerly known as American Cyanamid Company and the current owner of the American Cyanamid Superfund Site, is working under a Consent Decree with the U.S. Environmental Protection Agency (USEPA) to implement the site-wide remedy at the American Cyanamid Superfund Site.
WH is moving forward with the implementation of the remedy of site soils, site groundwater, and a majority of the remaining impoundments still requiring remediation, as described in the Record of Decision issued by USEPA on September 27, 2012. The WH team has invested significant resources in the engineering and design of this remediation program. Construction of the groundwater control, extraction, treatment, and reinjection system began in early 2017 and is expected to take two years to complete.
Pfizer/WH completed a comprehensive Focused Feasibility Study (FFS) process, which included an extensive evaluation of available environmental cleanup technologies for Operable Unit 8 (OU8), also referred to as Impoundments 1 and 2. Based upon this FFS, on May 23, 2018, USEPA released its Proposed Plan to address the impoundment materials. USEPA held a public meeting to explain the Proposed Plan and accept public comments. USEPA will evaluate the comments and is expected to select a final remedy in a Record of Decision.
Over the past three decades, a number of significant measures have been taken to remediate portions of the site and protect human health and the environment. The following is a summary of accomplishments at the site, including efforts completed prior to Pfizer’s involvement.
- For the past 30 years, a bedrock groundwater extraction well system has operated in place to control the migration of groundwater through continuous pumping and treatment. This system pumps a minimum of 650,000 gallons of groundwater per day that is subsequently treated offsite at the neighboring public wastewater treatment system. This system will continue to operate until the groundwater component of the Site-wide Remedy is constructed and operational.
- Remedial actions have been concluded for Impoundments 11, 14, 18, 19, 20 and 26, and each of these has been closed with No Further Action (NFA) required.
- Waste materials in several other areas have been remediated (including Lagoons 6, 7, 8, and 9A; and Impoundment 25).
- Iron oxide material located in Impoundments 15 and 16, and the former drying bed area, was excavated and transported off-site. Over 147,000 tons of iron oxide was transported off-site by rail for recycling.
- Approximately 70 acres and 1 million cubic yards of waste have been remediated to date.
- Approximately 10 million gallons of pumpable tars have been removed from the Site and treated through fuel blending operations and recycling/reuse.
USEPA inspects Superfund sites every five years to ensure that completed cleanups remain fully protective of human health and the environment. The American Cyanamid Superfund Site Five-Year Review was completed in 2014 and is available on USEPA’s website.
