The following information and images are from a site visit on May 1, 2025.
The site visit was conducted and the report compiled by Alex Thompson
of the EAP.
Field Notes: The system pulls petroleum rich liquids and vapor from the monitoring wells.
The contents travel to the treatment vehicle via 2" hoses (blue: featured in photos). Vapor
is pressurized and treated then purged into the surrounding area. The system removes
free product and contains it. Remaining liquids travel to the treatment trailer where it is
filtered through a series of carbon and conventional filters. The clean liquids are then
discharged into the nearby waterway, in this case a stream, which was pre-approved with
the permit from DWQ. The daily contents of the free product are removed from the
system and stored in an on-site 330 gallon liquids container (photo included).
The following photos were taken starting at the south-western extent facing north-east
and traveling north-east through the tank farm.
