Site Description
March 2016 Diesel Release
In March 2016, a release was reported after an employee observed fuel seeping to the surface through a crack in the asphalt pavement. Diesel was being pumped through a distribution line beneath the release location and was the source of the leak. This was confirmed after removal of the asphalt and excavation of overburden soil. The volume of the release and the length of time that the release occurred are unknown.
On March 23, 2016, an Interim Action was performed to investigate the nature and extent of contamination, including excavation of contaminated soil. Additional soil excavation occurred on March 30, 2016. An Interim Action is a partial or short-term cleanup of contamination and is meant to reduce exposure to harmful contaminants while a long-term cleanup up plan is worked on. The excavation continued vertically to about 20 feet below ground surface. The extent of the excavation was limited on the west side due to presence of a building. A soil sample collected from the sidewall at the west extent showed contamination concentrations above state cleanup levels. About 212 tons of petroleum-contaminated soils were removed and properly disposed during this action.
Three groundwater monitoring wells and one recovery well were installed on April 27 and 28, 2016. During installation, the soil was field screened and sampled. After the well installations, diesel was observed in two wells. Sampling from the wells revealed contamination above state cleanup levels. An extraction well was installed beneath the point of release. A total of 50 gallons of product was removed during eight recovery events using a vacuum extraction truck. Later measurement of the diesel in the recovery well was 2.5 feet on August 5, 2016.
January 2017 Gasoline Release
In January 2017, a gasoline release was reported; the amount of the release is unknown. The source of the release is believed to be an underground distribution line and shallow groundwater is impacted.
