MEMORANDUM

To: Charlotte Jesneck, Branch Head, Inactive Hazardous Sites Branch
From: Jeff Welti, Corrective Action Branch, UST Section, Washington, NC
Subject: Referral - U.N.X Incorporated Property 200 W. 9th St. Greenville, Pitt Co. NC
Incident # 93386 - Rank L25R

Please find attached the Report of Contamination for the U.N.X. property in
Greenville, Pitt Co. NC. The Underground Storage Tank (UST) Section received the
February 18, 2019 report on May 10, 2019. MTBE below 2L, benzene slightly above
2L and other petroleum detections were identified during the investigation. The
report notes possible vent pipes at the southern corner of the white roofed building
along Ficklen Street (see map), however UNX is reportedly unaware of any USTs on
the property and the consultant was not able to confirm tanks using a hand probe.
Two monitoring wells located on either side of the possible vent pipes show benzene
at 2.2 ppb (TMW-12) and ND for TMW-3. The site is ranked low and in the process of
being closed out with a Notice of Residual Petroleum (NRP) for soil and groundwater.
Non-petroleum constituents were detected in the groundwater (TMW-8) above 2L
Standards.
