LOT 46 VALLEY GARDENS TCE
IA | EPA ID IAN000705485
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.
