Gasoline Dispensing Facility, Reno, Nevada
Recently, site closure was achieved for a site which was considered one of this major oil company’s
largest liability retail sites in the country. BAI was responsible for characterizing and remediating
contamination (free-phase product, BTXE, MTBE, and TPH) in soil and groundwater resulting
from a 15,000 gallon gasoline underground storage tank release. The release was located in
close proximity to a public utility municipal well (~1,000 feet). Characterization activities included:
soil and ground-water sampling via installation of six on-site and ten off-site monitor wells,
completion of a constant rate aquifer test, and completion of a soil vapor extraction (SVE) and
air sparge (AS) pilot test (including helium tracer gas test). Remediation activities included:
immediate recovery of free-phase product, installation of five AS wells, conversion of five monitor
wells to SVE wells, and installation of an AS/SVE system. Additional activities completed included:
completion of aquifer test for the municipal well, evaluation of hydrogeologic conditions in the
vicinity of release site and municipal well, design and installation of air sparge system
(“air sparge curtain”) immediately up-gradient of municipal well, evaluation of the capacity of the
existing municipal well head treatment stripping tower for treatment of MTBE, and completion of
contaminant transport model to determine possible concentrations and travel time of MTBE from
site to municipal well.
Remediation of contaminants at the site was extremely successful, and BAI was able to
obtain site closure. In addition, BAI was able to assist the client through the application process
for Nevada Petroleum Fund reimbursement and obtained the maximum possible reimbursement
for all remediation activities allowed under the program.

Casa de Sunrise Development, Peoria, Arizona
BAI provided full service civil engineering for this 40-acre development in Peoria, Arizona. The development consists of 29 single-family residential ranch lots, approximately one acre each, in this exclusive area of Peoria.
On-site engineering services included:
• Site design
• Grading and drainage
• Water and sewer utility layout
• Paving plans
Off-site engineering services included:
• Paving and striping plans
• Adjacent street design
BAI subcontracted landscape architecture and surveying services. BAI also prepared construction plans for the project.
A major hurdle for this project was the requirement to retain a large volume of storm water. The drainage study resulted in the design and installation of 36-inch diameter underground stormwater pipes manifolded to an on-site retention basin.
The developer is preserving the property's natural desert flora of Saguaro Cacti, Palo Verde, Bursage, Creosote, and Sagebrush.

Municipal Well Drilling, Las Vegas, Nevada
BAI has been responsible for the construction management and design of more than 15 large diameter municipal water wells throughout the Las Vegas Valley for a wide variety of municipal water suppliers. These wells were constructed to depths exceeding 1,000 feet with production casings up to 20-inches in diameter. BAI field hydrogeologists performed around-the-clock supervision of the borehole construction as well as collection and lithologic logging of the drill cuttings. BAI senior hydrogeologists and engineers were responsible for adherence to the drilling specifications, management and interpretation of geophysical logging of the borehole, and final design of the well including well screen slot size and filter pack radation.
All of the wells were developed using swabbing and airlifting techniques during which time production water was monitored for sand production. Aquifer step-test and continuous flow tests were performed at rates up to 2,000 gallons per minute. Water quality parameters and sand production were monitored during testing and final water production analytical samples were collected at the end of testing.

Ready Mix and Aggregate Facility, Nevada
BAI assisted a multi-national ready mix and aggregate processing corporation with exploration, permitting, and development of a significant high quality mineral deposit which ultimately resulted in expansion of operations.
After reviewing existing literature, conducting field investigations, and drilling for core samples, BAI located a suitable site. The site was very close to where material would need to be transported thereby providing large potential savings to the client.
BAI investigated potential conflicts and permitting issues related to the acquisition of surface and mineral rights to lands identified for mineral development. Potential obstacles preventing active mining included existing encumbrances on the land, biological resources, and cultural resources. By working in conjunction with Federal, state, and local entities, BAI was able to lead the client through the permitting process and obtain regulatory compliance with the following:
• National Environmental Policy Act (NEPA)
• National Historic Preservation Act (NHPA)
• Endangered Species Act (ESA)
• Federal Land Policy Management Act (FLPMA)
• Las Vegas Resource Management Plan (RMP)
