The Bradshaw Auto site is located in Provo, Utah, and is surrounded by various commercial
properties. The site's history dates back to 1919, with several ownership changes before
becoming an automotive service facility in 1950. The facility operated for approximately 20 years
before the building was demolished, leaving the site vacant. From 1987 to 2003, the property
was managed in trust, during which environmental assessments and remediation activities were
conducted as part of the state's Voluntary Cleanup Program (VCP). These efforts included
groundwater and air sampling, soil excavation, and installation of a remediation system. In 2014,
the VCP agreement was terminated without a closure plan.

Previous environmental studies have identified significant contamination of groundwater with
tetrachloroethene (PCE), trichloroethene (TCE), and other solvents, exceeding EPA Maximum
Contaminant Levels. Chlorinated solvents and petroleum hydrocarbons were released at the site
through a sump drain located on the property. A Preliminary Assessment conducted in 2021
recommended further off-site sampling due to these known contamination issues. Subsequently,
a Site Inspection (SI) was carried out to collect groundwater and soil gas samples to determine
current site conditions and evaluate exposure risks. The SI confirmed that elevated levels of
PCE and TCE persist on-site, appear to be migrating from the former Bradshaw Auto Facility,
and may be influenced by a nearby, unrelated former dry-cleaning operation.

According to the SI, the primary environmental concern is vapor intrusion (VI) from chlorinated
solvents in groundwater. This poses potential exposure risks, especially near and downgradient
of the site. Although most areas appear to be low risk, elevated solvent levels suggest possible
VI risks requiring further sampling to fully assess.
