Home My WebLink AboutIH2572_20231025_Memo To File MEMORANDUM October 25, 2023 TO: IHSB File FROM: Brett Engard, Hydrogeologist Inactive Hazardous Sites Branch RE: T&T Supermarket 261 West Fleming Drive Morganton, Burke County IHSB ID# NONCD0002572 T&T Supermarket (site) was referred to IHSB from the Asheville Regional Office (ARO) UST Section, based on to groundwater samples collected from a 1-inch diameter temporary groundwater monitoring well. The temporary groundwater well was installed on February 28, 2000, near the former pump island as part of a Phase I LSA then sampled on March 1, 2000. At the request of the UST Section, the temporary groundwater monitoring well was resampled on March 30, 2000. PCE, TCE, 1,1-DCE, 1,1-DCA, and 1,1,1-TCA, and petroleum-related compounds, were detected in groundwater. The T&T Supermarket building is visible on the January 16, 1962, DOT Aerial Image (m0203_9685). Entered the highest concentration of the two groundwater sampling events data (March 2000) into the DEQ Risk Calculator. Both Residential and Commercial groundwater to indoor pathway exceeded the applicable risk; see attached. The site is located upgradient of Hunting Creek (DWR Classification: WS-IV), downgradient of Breeden Poultry/Case Farms processing plant (UST Incidents #6445/AS-414 & #6446/AS-415, AST Incident #11780/AS-88152); UST Incident #6446 remains open and has been admitted to the UST State Lead Program. One groundwater monitoring well (MW-3) on the Case Farms property is upgradient of the subject site; however, no groundwater monitoring data could be located. Case Farms is also a Hazardous Waste Section (HWS) facility (SQG: NCD982165524) consisting of vehicle maintenance, used oil, antifreeze recycling, batteries, parts washer (nonhazardous fluid), and Safety Kleen’s solvent cleaner (1988-1998). Contacted C. LaFond, UST Regional Supervisor, in ARO regarding data from MW-3. Upgradient/side gradient to the subject Site is Superior Cleaners (DC120003), a Dry-Cleaning Solvent Cleanup Act (DSCA) Program site. Groundwater monitoring well MW-6 is upgradient, north of W. Flemming Drive. MW-16 is side-gradient, adjacent to the Site, and the closest groundwater monitoring well in proximity to the subject Site. MW-6 had PCE as high as 2.6 ug/L (2018), and TCE at approximately 1 ug/L. MW-16 has not had detectable PCE, but TCE is approximately 5 ug/L. Spoke to the DSCA project manager, Mike Cunningham, about the Subject Site. Discussed the historical UST report, located the former pump island (Google Street View) where the temporary well was located, and that the subject site is build into the side of the slope with a walkout basement. Mr. Cunningham stated the following: • Groundwater flow is generally to the south toward Hunting Creek, • 1,1,1-TCA is not associated with dry cleaning sites, • There are utilities in the area that could have transported affected groundwater, • Would talk to the DSCA contractor regarding the subject site, • A soil gas/VI assessment had been completed. A review of the May 29, 2020, VI Report (Heart & Hickman), indicated that TSG-10 located at the adjacent ABC Store has a Residential Hazard Index of 2.6, but an acceptable non-Residential Hazardous Index (0.21). M. Cunningham indicated that he spoke with the DSCA contractor and may complete some GW sampling between the DSCA and IHSB Sites and perform some SG sampling at the IHSB Site. Contacted NCDOT Morganton, Burke County Maintenance, and spoke to J. Buchanan regarding utilities in the vicinity. He sent the attached screen shot of the sewer line. Contacted the District Office for potential additional utility drawings. Talked to J. Butler in the District Office, who provided a proposed road improvement plan (1954) of the area; see attached. The plans depicted a groundwater supply well upgradient of the subject Site, on the parcel north of West Flemming Drive, and east of Superior Cleaners. Contacted the City of Morganton and spoke to M. Hall regarding utilities in the area. He forwarded two maps of the sewer and water lines in the area; see attached. %Aª %Aª !²%Aª %Aª %Aª%Aª%Aª %Aª%Aª%Aª%Aª%Aª%Aª%Aª %Aª %Aª%Aª%Aª %Aª %Aª%Aª%Aª %Aª%Aª %Aª%Aª %Aª%Aª%Aª %Aª %Aª %Aª %Aª %Aª%Aª %Aª %Aª%Aª%Aª %Aª%Aª %Aª %Aª %Aª %Aª %Aª%Aª %Aª %Aª %Aª%Aª %Aª %Aª %Aª%Aª%Aª %Aª %Aª%Aª%Aª %Aª %Aª%Aª!²!² !² !² !² !² !² !² !² !² !² !² !² !² !² !² !² !² !² !² !² !²!² !² !² !² ! ! º º ! ! ! !! ! ! !!!! ! ! ! !! ! ! ! ! ! ! ! ! ! ! !! ! ! ! ! !! ! ! ! ! ! ! ! ! ! ! ! ! ! 2 2 2 2 2 2 2 2222 2 2 2 2 2 2 2 2 2 2 2 2 2 ! ! ! ! ! ! ! ! ! ! ! ! ! !! ! ! ! ! !!! ! ! !! ! ! !! ! ! ! ! ! ! ! ! !! ! ! ! !!! ! ! ! ! !! ! ! ! !! ! ! ! !! ! !! ! ! !!!! ! !!! !! ! ! ! ! ! ! ! ! ! ! ! ! ! !! ! ! ! ! !! ! ! ! !! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! !! ! ! ! ! !! ! ! ! !! ! ! ! ! ! ! ! ! ! ! ! ! !! ! !!! !! 2 2 2 2 2 2 2 2 2 2 2 2 2 22 2 2 2 2 22 2 2 2 22 2 2 2 2 2 2 2 2 2 2 2 2 22 2 2 2 2 22 2 2 2 2 22 2 2 2 22 2 2 2 2 2 2 22 2 2 22 22 2 222 22 $ $$$ $ $ $ $ $ $ $$$ $ $ $$ $ $ $$ $ $ $$ $$ $ $ $$$ $ $$ $ $ $$$ $ $ $ $ $ $ $$$ $ $ $$ $ $ $ $ $ $ $$ $$ $ $ $$$ $ $$ $ K KKK K K K K K K K K K K K K K K K K K K K KK K K K K KKK K KK K 8 in V i t r i f i e d C l a y ( V C ) 48 in C o n c r e t e 8 in Vitrifie d Clay (V C ) 21 i n Vitr i f i e d Cla y ( V C ) 8 in Vi t r i f i e d Clay (VC) 8 in Vitrif i e d Clay ( V C ) 30 i n Co n c r e t e 8 in V i t r i f i e d Cla y (VC ) 8 inVitrif i e dClay ( V C ) 8 inVitr i f i e d C l a y (VC ) 8 in Vitr i f i e d Cla y ( V C ) 8 in Vitrified Clay (V C ) 12 inVitrif i e dClay ( V C ) 15 i n Vitr i f i e d Clay ( V C ) 21 i n Vitr i f i e d Cla y ( V C ) 8 in V i t r i f i e d Cla y (V C ) 8 i n V i t r i f i e d C l a y ( V C ) 8 in V i t r i f i e d C l a y ( V C ) 8 in Vi t r i f i e d C l a y ( V C ) 8 i n V i t r i f i e d Cla y (V C ) 8 in Vitr i f i e d C l a y ( V C ) 8 in Vitrif i e dClay(VC) 15 inVitrifiedClay (VC ) 8 in Vit r i f i e d Clay (VC) 12 i nCas t Iro n ( C I ) 2 in N o tSpeci f i e d 8 i nCa s t Ir o n ( C I ) 12 in C a s t I r o n ( C I ) 6 in P o l y v i n y l Chlo r i d e ( P V C ) 6 inCas t Iro n ( C I ) 2 in Cas t I r o n (CI ) 6 in D u c t i l e Iro n ( D I ) 6 in C a s t I r o n ( C I ) 6 inCast Iron (CI) 8 in C a s t Iro n ( C I ) 6 i n C a s t Iro n (C I ) 6 in Polyvinyl Chloride (PVC) 6 in C a s t I r o n ( C I ) 6 in Cast Ir o n ( C I ) 6 in D u c t i l e I r o n ( D I ) 12 in Cast I r o n ( C I ) 6 in Cas t Iron(CI) 16 in Polyvinyl Chloride (PVC) 8 in Ca s t I r o n ( C I ) 6 in P o l y v i n y l Chl o r i d e ( P V C ) 8 in Ca s t I r o n ( C I ) 12 in D u c t i l e I r o n ( D I ) 6 i n C a s t I r o n ( C I ) Fores t S t Clin e St Ba y S t HerronSt Perry S t Coal Ch u t e R d Alw r a n S t SAndersonSt Jon e s S t Ramsey S t S College S t CoxSt Rand S t W Fleming Dr S S t e r l i n g S t !²Hydrants %AªWater Valves Water Lines $$K Clean Outs !!2 Manholes Gravity Sewer Lines Pressure Sewer Lines Morganton City Limits Parcels ± 0 250 500125 Feet City of Morganton Water & Sewer Mapping 1 inch equals 100 feet DISCLAIMER: The information contained on this site is furnished by government and private industry sources and is believed to be accurate but accuracy is not guaranteed.
