EPA Superfund Site

MAYWOOD CHEMICAL CO.

NJ | EPA ID NJD980529762

About this site’s exposure pathways: As of January 2025, the Maywood Chemical Company Superfund Site is considered "Insufficient Data to Determine Human Exposure Control Status" because EPA is overseeing an investigation and feasibility study by a responsible party to fully identify the nature and extent of chemical contamination in groundwater associated with the chemical company operations. It is believed that groundwater is not used for potable purposes in the immediate vicinity of the site due to the availability of a public water supply. Benzene, toluene, lithium and other contaminants have been identified in groundwater at the site and will be addressed in a future groundwater remedy decision. EPA is also overseeing the implementation of a remedy to address chemically contaminated soil in accordance with a 2014 Record of Decision (ROD). Separately, the U.S. Army Corps of Engineers (USACE) is cleaning up radiologically contaminated soil and building debris under the Formerly Utilized Sites Remedial Action Program (FUSRAP). EPA is also overseeing activities by the USACE to address groundwater impacts associated with the federal government-owned 11-acre portion of the site, known as the Maywood Interim Storage Site or MISS.

EPA currently anticipates that there will be sufficient data to make a Human Exposure evaluation by September 2026 when the ROD is signed.

EPA ensures community participation throughout the remedial process by meeting with residents and affected stakeholders, issuing public notices, and updating fact sheets. A site profile has been established on the EPA website to keep the community informed of recent progress at the site. A public information office is near the site in downtown Maywood, New Jersey.
