EPA Superfund site
LOT 46 VALLEY GARDENS TCE
Human exposure is 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 December 2025, the Lot 46 Valley Gardens TCE site is considered Insufficient Data to make a Human Exposure evaluation (HEID). While there has been considerable groundwater sampling to rule out current ingestion of contaminated groundwater, more air monitoring is required to fully assess the vapor intrusion pathway. EPA is in the process of conducting air sampling to gather more data. EPA anticipates that sufficient data to make a Human Exposure determination will be available by Spring 2026, due to progress with the monitoring program.
