2.0 SITE LOCATION, DESCRIPTION, AND HISTORY
The Site consists of two closed dry cleaning operations located in North Belmont, Gaston
County, North Carolina. These two areas are referred to as "Source Area A" and "Source
Area B" (Figure 2-1). Source Arca A, which was operated by the Untz family from 1960
to 1975 as a dry cleaning business, is located at Roper's Shopping Center in Land Lot 5,
Parcel 15-lSA on Woodlawn Avenue. The shopping center included Roper's Furniture
Store, a Baptist church, and a cabinet manufacturing shop. The former dry cleaning facility
is approximately 0. 75 acre in size and is bounded to the east and west by residential
neighborhoods, to the north by a cemetery and an undeveloped wooded tract, and to the south
by North Belmont Elementary School., Source Area B is located at the northeastern corner
of Acme Road and Suggs Road in Land Lot 11, Parcel 15-18. This parcel has been converted
to residential property. The majority of the area surrounding Source Area B is residential
with a few small businesses. A cabinet shop is located to the north. A previous refrigerator
repair shop and a machine shop were also suspected to be potential sources of contamination.
The refrigerator repair shop, now closed, is located at the intersection of Julia Street and
Acme Road in Land Lot I 5-1 SA, Parcel 32. This is a small commercial strip area with
residential property surrounding the Site, except for a cabinet shop and a well drilling
company located to the cast. The machine shop is located at the corner of Acme and
Centerview Roads and is encompassed by residential neighborhoods. Figure 2-2 shows the
approximate study area.

required in Appendix B. System control shall be completely automatic. Each treatment
system shall be capable of operating continuously, 24 hours per day. The treatment units
shall be installed at required individual residences in such a way as to minimize
inconveniences to the residents. In some cases, residents may require electrical and well
house upgrades to handle the installation of the new systems. The price for these upgrades
shall be included in the lump sum price supplied in Table 4-2. After six months of operation,
each installed RCFU will be sampled and analyzed for volatile organic compounds in

Appendix A of this document.
3.4.2 CONSTRUCTION QUALITY ASSURANCE PLAN
The Contractor shall submit a draft CQA Plan. The CQA Plan shall be prepared in
accordance with Construction Quality Assurance for Hazardous Waste Land Disposal
Facilities (EPA, 1986). The CQA Plan shall then be finalized and submitted in accordance
with the project schedule. At a minimum, the draft CQA Plan shall provide requirements for
the following elements:
• Responsibility and authority of all organization and key personnel involved in the
remediation action construction
• CQA Personnel Qualifications-The contractor shall establish the mm1mum
qualifications of the CQA Officer and supporting inspection personnel.
• Inspection Activities-The Contractor shall establish the observations and tests that
