Manor Market Deli

The Site is defined as total petroleum hydrocarbons in the gasoline range, benzene, toluene, ethylbenzene, xylenes and methyl tert-butyl ether (MTBE) in the soil and groundwater. The Site is also defined as lead in the groundwater.

The property was used as farmland until the current improvements were constructed in 1982. The property is occupied by a 7,000 square foot one-story, multi-tenant retail building. Manor Market is a deli store that includes retail gasoline sales using three gasoline pump islands with twin dispensers under one canopy located in the southeast portion of the Property.

The property was previously the location of Crystal Cleaners, a former dry cleaning operation in tenant Unit D on the west end of the building. Crystal Cleaners was previously enrolled in the VCP as project number NW0179. A No Further Action (NFA) determination was issued by Ecology in 1999. The NFA included placement of a Restrictive Covenant that prohibited activities that would result in the release of contamination contained as part of the cleanup without Ecology's approval.

Potential contaminant sources on the Site consist of three former 12,000-gallon, single-walled, underground storage tanks (USTs) that were installed in 1982. The former US Ts, two dispensers and associated piping and equipment were removed in 1998 when the existing UST system was installed. Soil contaminated with petroleum hydrocarbons was found beneath the Property during the upgrade. The former US Ts were replaced with two 10,000-gallon double-walled steel tanks and new dispensers, piping and other ancillary equipment with leak detection capabilities. One of the USTs is a dual compartment (4,000 and 6,000 gallon tanks) which holds mid-grade and premium-grade gasoline. The other 10,000-gallon UST holds regular-grade gasoline.

Groundwater samples collected in 2015 and 2016 indicate two distinct patterns. MW-1 and MW-4 contain only benzene and MTBE at concentrations exceeding Method A cleanup levels. MW-6 contains TPH-G and benzene at concentrations exceeding Method A cleanup levels. These results suggest a similar source in MW-1 and MW-4 and potentially a separate source in MW-6. Periodic groundwater monitoring is being conducted on the Site.

Analysis for the presence of chlorinated solvents related to dry cleaning in groundwater has been conducted once at the following monitoring wells in either 2015 or 2016: MW-3, MW-4, MW-7, MW-8, MW-9 and MW-11. There have been no detections.

This site is in our Voluntary Cleanup Program, which provides technical help to owners of contaminated sites.

Voluntary Cleanup Program customers pay fees to cover our costs for technical help and reviewing cleanup reports. Sites in this program must meet the same cleanup standards as sites Ecology manages under legal orders.
