Inspection Summary:
Jim Gonsiewski of the WSRO on site at 10:10 AM 9/23/2021. Met with Greg Flasinski of Weston Solutions. Toured the
site. First visited the old remediation area. Previously a pump and treat system was located at the site. According to David
Kane of Weston Solutions, in 2009 the system was shut down due to extensive damage that occured during construction of
the Block 43 Apartments/Cottages student housing. 16 wells, a remediation system building, and associated underground
piping and valves were destroyed during the construction grading and work. Additionally, another 6 wells were damaged.
A remediation injection system (injection of diluted Newman Zone emulsified vegegtable oil in four injection wells across the
site) was permitted in February 2019. This system was abandoned in September 2019.
Observed the location of the new remediation system along Blunt street in the paved area along the southwestern boundary
of the site. Area appeared to have good access and room to install the new system.
