From at least 1895 through the early 1980s, the site was occupied by various residential and commercial occupants. Commercial occupants included: medical offices, restaurants, a bakery, beauty and barber supply, jeweler, department store, hardware store, auto accessory store, men's furnishings, grocery store, shoemaker, wall paper and paint store, alarms and electrician's store, meat store, drug abuse office, saloon, drug store, billiards hall, roofing company, bicycle
store, barber, newspaper company, women's clothing, churches, a hotel, and a florist. A gasoline filling station and automotive repair station were present at the northeast corner of the site from at least 1936 through the 1940s [Hickok Oil and Micham Barber Hi-Speed Gas (1327 N. Detroit Avenue)]. By 1951, the gasoline filling station was not in use and the automotive repair station was converted to a store. The site structures were demolished during the 1970s/1980s. Since the late 1980s, the site has consisted of vacant grassy land, scattered trees, and a concrete-paved sidewalk.
One approximately 550-gallon UST, presumed to be a former heating oil UST, was identified on the northeastern portion of the site. Soil samples collected from around the perimeter of the UST contained trace levels of toluene and PAHS at concentrations below the VAP GDCS and BUSTR ALs. Petroleum VOCs and PAHs were not detected in the groundwater samples collected from the borings advanced in the area of the UST. The suspected heating oil UST should be removed in accordance with local and state requirements and the soil beneath the UST and walls of the UST cavity sampled.
VOCs, PAHs, and/or metals were not detected in soil or groundwater at the site at concentrations above the VAP standards or BUSTR Action Levels with the exception of lead in groundwater sample GP-4-W. The detected lead concentration in groundwater sample GP-4_W is above the VAP GUPUS, which is an ingestion standard and assumes that groundwater is being utilized for drinking water. The site and surrounding area receives its drinking water from the City of Toledo municipal water system and drinking water wells are not permitted within city limits. Therefore, the groundwater ingestion pathway is incomplete. Lead is a metal and does not volatize, therefore, there is no vapor intrusion concern.
Based on the results of the Phase II ESA, the off-site RECs identified in the Phase I ESA conducted by CT, including the former easterly adjoining gasoline filling station, and the former easterly adjoining dry cleaner do not appear to have adversely impacted the site.
