The Route 31 Sludge Disposal Site is an area in the eastern portion of Warren County mostly within Washington Township, south of Washington Borough, which has been impacted by industrial per- and polyfluoroalkyl substance, also referred to as PFAS, contamination.

The EPA will be discussing its work so far and upcoming plans at a public meeting soon:

Date: Wednesday, April 30, 2025

Time: 6:30 p.m. – 8:00 p.m.

Location: Warren County Technical School – Cafeteria

  1500 Route 57, Washington, NJ 07882

 

After the New Jersey Department of Environmental Protection, or NJDEP, asked the EPA to take over the investigation and cleanup PFAS contamination in November 2024, the EPA developed a plan to swiftly protect community members from PFAS contamination within an initial study area, outlined in yellow on the map shown on this page. The dotted line shows the study area expansion in early 2025. The EPA’s initial work at the site consists of three parts:

 

1.  Providing Bottled Water

   The EPA is currently distributing free bottled water to about 180 homes where the EPA sampled the drinking water wells and found PFAS contamination above the EPA’s Maximum Contaminant Levels, or MCLs.

2.  Sampling Drinking Water

The EPA has sampled almost 350 wells at residential and commercial properties to determine if drinking water at each property in the EPA’s study area is contaminated. If early results have shown contamination in drinking water, the EPA has offered the bottled water delivery service. This effort has concluded, and the EPA is evaluating the data set to determine if the drinking water study area should be expanded later in 2025 or 2026.

3.  Installing Treatment Systems

The EPA will be installing individual water treatment systems to address contamination and protect residents and workers at eligible properties after they have been sampled by the EPA. After the EPA receives the sampling results, if a property’s drinking water has contaminant levels above the EPA’s MCLs, that property will be eligible to receive a free water treatment system called a Point-of-Entry Treatment system. This work is planned for summer-fall 2025 once the EPA’s subcontract is set.

 

Additionally, the EPA has sampled soil in several farm fields where PFAS-contaminated sludge from a historic textile mill was spread between the late 1950s and 1970s and will be sampling the Musconetcong River in coordination with the NJDEP and other stakeholders. Results are pending.

The EPA will continue keeping the public informed as the investigation progresses. For more detailed information, please see the Documents section of this page which includes the EPA’s fact sheet, December 10th public meeting presentation and NJDEP referral letter to the EPA.

The EPA's current investigation is known as an integrated assessment, designed to study and address the most immediate risks to people’s health and the environment while the site is evaluated for inclusion on the EPA’s Superfund National Priorities List. If the site is added to the EPA’s National Priorities List, it would be eligible for federal funding to pay for extensive, long-term cleanup actions under the EPA’s Superfund program. Listing the site also allows for robust engagement with communities impacted by the PFAS contamination. Superfund gives the EPA strong authority to hold the polluters that will be identified as potentially responsible parties at this site responsible and accountable for the cleanup.

Background:

The NJDEP first discovered the contamination in 2019 during routine drinking water well sampling at a local business. On November 7, 2024, the NJDEP referred the site to the EPA to address high levels of PFAS in soil and groundwater. The main source of PFAS contamination is thought to be historic waste sludge from a former textile manufacturing facility, known as Castle Creek Fabrics and Northern Dyeing Corporation. The sludge was spread over at least 45 acres of farmland from the late 1950s through the 1970s. The EPA took over and is now leading the investigation.

Definitions:

PFAS: Per- and polyfluoroalkyl substances are a group of man-made chemicals that are not found naturally in the environment. The two types of PFAS made in the largest amounts in the United States were PFOA and PFOS. PFAS can be found in air, soil, and water as a result of manufacture and use. They do not break down in the environment very easily. PFAS can seep through the soil into groundwater and may adversely impact people’s health and the environment. See https://www.epa.gov/pfas/our-current-understanding-human-health-and-environmental-risks-pfas for more information.

MCLs: The EPA’s Maximum Contaminant Levels are science-based standards for the maximum level allowed of a contaminant in drinking water.
