The former Johnson Oil Bulk Plant site consists of a vacant 1.38 acre parcel located at 719 East 12th Street on the north side of Bloomington, Monroe County. The bulk facility was initially constructed by Sunoco Oil Company in the 1950's or 1960's. Johnson Oil Company purchased the facility in the late 1970's and operated it until 1993. In 1993 the facility was closed and the building and aboveground storage tanks (ASTs) were removed. Petroleum impacted soil and groundwater was encountered beneath the site during a subsurface investigation performed in 1999. In December 2000, seven groundwater-monitoring wells were installed at the site to evaluate potential impacts to groundwater for the contaminants of concern benzene, toluene, ethylbenzene, and xylene (BTEX), methyl-tertiary-butyl-ether (MTBE) and polynuclear aromatic hydrocarbons (PAHs). Initial groundwater sampling events detected benzene above the nonresidential cleanup goal in one of the seven monitoring wells at concentrations ranging between 330 parts per billion (ppb) and 390 ppb during three consecutive quarters. As a result, petroleum impacted soil was removed from the vicinity of the impacted groundwater monitoring well. A total of 539 tons of petroleum impacted soil were excavated and transported off-site to a special-waste landfill for disposal.
Remediation activities as outlined in the remediation work plan have been completed at the site. The remediation work plan proposed the limited removal of impacted soil in conjunction with the monitoring of groundwater for eight consecutive quarters. The contaminants of concern initially detected in the soil and groundwater are below the IDEM VRP Tier II nonresidential cleanup levels and as such, the remediation effort is considered complete.
