EXECUTIVE SUMMARY
Riverside Grocery is located at 107 Riverside Drive in McAdenville, Gaston County, North Carolina. The
site is currently owned by CB Investments Properties, LLC and is a former petroleum retail facility. The
property currently operates as the office for Cloninger Bell Surveying Mapping, PLLC. The site is covered
by concrete and asphalt, with trees on the periphery. The site had one UST basin southeast of the canopy
which contained one 6,000-gallon gasoline, one 4,000-gallon gasoline and one 4,000-gallon diesel USTs.
These USTs were removed from the site on August 30, 2022. The surrounding properties are residential.
According to the receptor survey results and correspondence with McAdenville Town Services, three
potable water supply wells are located within 1,500 feet of the source area. None of these water supply
wells are located within 250 feet of the source area. Public water is available to the subject site and to all
surrounding properties. The South Fork of the Catawba River is located across the street from the
property, approximately 200 feet southwest of the source area.

A CAP has not been implemented at the site.

On October 11, 2023, seven monitoring wells and one telescoping well were gauged, purged, and
sampled. The concentrations of benzene, toluene, ethylbenzene, xylenes, MTBE, naphthalene,
isopropylbenzene, n-propylbenzene, 1,2,4-trimethylbenzene and/or 1,3,5-trimethylbenzene reported in
the ground water samples collected from MW-1 and MW-6 exceeded the MACs. The concentrations of
benzene, toluene, ethylbenzene, xylenes, and naphthalene reported in the ground water sample collected
from MW-1 exceeded ten times the 2B Standards. All the reported contaminant concentrations were
below the GCLs.

Based on this information, the risk classification for the site should remain intermediate risk. Quarterly
ground water monitoring should continue at the site to establish plume stability. The next sampling event
is tentatively scheduled for January 2024.

5.0 CONCLUSIONS
 On October 11, 2023, seven Type II monitoring wells and one telescoping well were gauged,
purged, and sampled. Ground water flow was generally to the southwest with a horizontal
gradient of approximately 0.011 feet per foot. The vertical gradient between paired wells MW-1
and TW-1 was approximately 0.179 feet per foot in the downward direction.
 The concentrations of benzene, toluene, ethylbenzene, xylenes, MTBE, naphthalene,
isopropylbenzene, n-propylbenzene, 1,2,4-trimethylbenzene and/or 1,3,5-trimethylbenzene
reported in the ground water samples collected from MW-1 and MW-6 exceeded the MACs. The
concentrations of benzene, toluene, ethylbenzene, xylenes, and naphthalene reported in the
ground water sample collected from MW-1 exceeded ten times the 2B Standards. All the reported
contaminant concentrations were below the GCLs. No free product was observed at the site.
 Based on this information, the risk classification for the site should remain intermediate risk.
Quarterly ground water monitoring should continue at the site to establish plume stability. The
next sampling event is tentatively scheduled for January 2024.

Notes:
• Area of the contaminant plume is calculated from Figure #8
• Height of the water column is calculated by subtracting the average depth to water from the average well depth of the referenced monitoring wells
• Volume of the contaminant plume is calculated by multiplying the area of the plume by the average height of the water column during each sampling event
• Effective porosity is assumed based on the sub-surface soil profile obtained from well construction records and soil boring logs
• Total mass was calculated by multiplying the total contaminant concentrations for the sampling event with effective volume
• Contaminant mass cannot be calculated in wells containing FP; therefore, the total contaminant mass is based on the known concentrations in the area for each sampling event.
