The site is a collection of historic, unlined landfills located near the intersection of 1860 South
Industrial Parkway in Provo, Utah. The landfill was in operation from the early 1940's through
1991 and likely received multiple waste streams including municipal refuse, wastewater
treatment plant sludge, organic solvents, and PCB contaminated animal carcasses.
Contaminants of concern that have been previously detected at the Site include arsenic, carbon
disulfide, chlorobenzene, ethylbenzene, mercury, toluene, xylenes, and pesticides.

In 2022, the Utah Department of Environmental Quality (UDEQ) investigated the site to
determine if hazardous constituents were migrating or have the potential to migrate off-site via
the groundwater, surface water, soil, and/or air pathways. Several metals and organics were
detected in the UDEQ samples, but there was not a consistent pattern of detections across the
site. The UDEQ found potential for impact from the landfill to site soils, ground and surface
water, and sediment, but the industrial nature of the area made it difficult to determine if they are
attributable to the landfill. There are no drinking water wells downgradient of the site, site surface
water is not used for recreation, there is very little foot traffic across the site, and what traffic
there is, is on paved surfaces or surface soil. Eight of the nine surface soil samples collected did
not contain any analytes above screening levels, and the one that did contain an analyte (i.e.,
Aroclor-1242) above the EPA screening level was below industrial screening levels for that
analyte indicating that targets are unlikely to be exposed to contaminants identified at the site.

Based on the review of the UDEQ results, The U.S. Environmental Protection Agency (EPA) has
determined that no further remedial action by the Federal Superfund program is warranted at the
referenced site, at this time. The basis for the no further remedial action planned (NFRAP)
determination is provided above. A NFRAP designation means that no additional remedial steps
under the Federal Superfund program will be taken at the site unless new information warranting
further Superfund consideration or conditions not previously known to EPA regarding the site are

disclosed. In accordance with EPA's decision regarding the tracking of NFRAP sites, the
referenced site may be removed from EPA’s Active site inventory and placed in a separate
Archive site inventory as an historical record if no further Superfund interest is warranted.
Archived sites may be returned to the Active site inventory if new information necessitating further
Superfund consideration is discovered.
