Residential UST's

A local threat to human health and groundwater quality.

Leaking residential UST’s pose a local threat to human health and groundwater quality.

HCI is often retained by major insurance providers to establish third-party coverage. Off-site soil and underlying groundwater contamination are used to establish third-party claims.

HCI uses a simple, three-pronged strategy to address most residential UST sites. The first step is to remove as much petroleum-saturated soil as possible during excavation activities. If left behind, this soil contributes to the persistent presence of an immeasurable sheen and dissolved contaminant plume.

The second step is to remove oil and grossly-impacted groundwater with a vacuum truck while the excavation is open. This greatly reduces the amount of time and money spent during later phases of the cleanup.

If necessary, HCI will implement the third component of this strategy: Removal of the remaining groundwater contamination via the installation and pumping of monitoring wells. Groundwater removal is typically achieved via enhanced fluid recovery (EFR).

HCI has successfully remediated hundreds of residential homeowner UST sites in densely-populated urban centers, as well as suburban communities. Unlike many contractors whose expertise ends with excavation activities, HCI is adept at the application of conventional methods as well as innovative technologies. For example, HCI does not routinely support houses to remove underlying impacted soil. Instead, we employ insitu remediation technologies, such as surfactant flushing, to desorb and capture residual oil. Similarly, while many contractors install costly pump-and-treat systems to remediate dissolved contaminant plumes, HCI uses insitu technologies, such as enhanced natural biodegradation and chemical oxidation. In many cases, the costs associated with conventional methods are orders of magnitude greater than that of in situ technologies.
