EPA Superfund site
FORMER KIL-TONE COMPANY
Human exposure is NOT currently under control
Data limitations: Proximity to a Superfund site boundary does not mean your property is contaminated. EPA site boundaries show the area designated for cleanup, not the full extent of contamination. Groundwater plumes can extend beyond site boundaries. This tool shows publicly available EPA federal data. It is not affiliated with or endorsed by EPA, and is not a substitute for a professional environmental assessment.
About this site's exposure pathways
As of May 2026, the Former Kil‑Tone Company Superfund site is considered “Current Human Exposure Not Under Control” (HENC). Sampling has found elevated arsenic and lead in soil, groundwater, surface water, and sediment in the vicinity of the former facility and downstream of the former facility. Residents, workers, and visitors may be exposed through direct contact with contaminated soils on residential and non‑residential properties and through incidental ingestion or inhalation of contaminated soil and dust, and contact with contaminated sediments and floodplain soils along the Tarkiln Branch.
Currently, the planned activities to address this pathway include:
- Completing cleanup and restoration of impacted residential properties near the former Kil‑Tone facility. All 88 residential properties have been addressed, and EPA approved the remedial action report in 2025.
- Continuing phased cleanup and restoration of more than 40 non‑residential properties, including the former facility property. Field work for 35 phase‑1 properties began in 2024; as of May 2026, soil excavation and backfill are complete at 13 properties, and design of phase 2 is complete. The design for phase 3 will begin in 2026.
- Continuing development of the groundwater Remedial Investigation/Feasibility Study (RI/FS).
- Performing the RI/FS for surface water and sediment in the Tarkiln Branch and its floodplain.
- Performing an RI/FS focused on an early, interim action for the Tarkiln Branch floodplain, planned for completion in 2026.
If you may be affected, you can reduce your exposure by avoiding contact with bare soils and floodplain sediments, keeping children and pets away from disturbed areas, washing hands after outdoor activities, and following posted signs and local health advisories. For more information, contact the EPA Community Involvement Coordinator Olivia Cappo via the site webpage or at (212) 637-3532 or [email protected].
EPA currently anticipates that human exposure will be under control by September 2045 because the Operable Unit 5 (OU5) remedial action addressing soil and related exposure pathways will be complete, non‑residential property cleanups will be finished, and institutional controls and verification sampling will confirm achievement of cleanup goals, as reflected in the Superfund Enterprise Management System the Superfund Enterprise Management System (SEMS).
