Site Description

Lakeshore Village Apartment
Lakeshore Village Apartment

The Lakeshore Village Apartments Site (currently known as Lake Washington Apartments) is located at 9061 Seward Park Avenue South, Seattle, Washington. The property consists of a low income housing development first constructed in 1948. The property covers approximately 16.5 acres and includes 34 buildings with 366 residential apartments. The housing development underwent renovation in the mid-1990’s.

Cleanup Actions

Part of the renovation process in the mid-1990s included removal of heating oil underground storage tank (UST) systems next to the apartment buildings. Diesel contaminated soil was identified and removed from 9 of the 18 UST locations. Contaminated soil was left in place at 4 of the UST locations, where either buildings or buried pipes were in danger of being undermined, or other structural hazards were found.

Groundwater Investigation

The 2010 Periodic Review concluded that groundwater had not been investigated and therefore the soil-to-groundwater pathway could be a concern. The 1998 No Further Action (NFA) determination was rescinded by Ecology in April 2010 since groundwater may have been impacted. 

In 2012, groundwater sampling was conducted near the 4 UST locations where soil contamination remained. Only one of the groundwater samples, which was collected near building 35, had a diesel range total petroleum hydrocarbon concentration exceeding the groundwater cleanup level. Three groundwater monitoring wells were installed in the vicinity of building 35. Groundwater monitoring results indicate that contaminated groundwater is contained within the property boundary and is not migrating off the property.

Regulatory Status

A NFA determination was issued by Ecology’s Voluntary Cleanup Program (VCP) in June 2013. A new Environmental Covenant was recorded with King County that supersedes the 1998 Restrictive Covenant. An Environmental Covenant restricts activities that might result in exposure to the contaminants. No additional cleanup actions were determined to be necessary. Confirmational groundwater monitoring is required every five years to confirm the long-term effectiveness of the cleanup action.

Periodic Review Results

The cleanup actions completed at the Site appear to be protective of human health and the environment. 

Soil and groundwater cleanup levels have not been met at the standard point of compliance for the Site; however, the cleanup action has been determined to comply with cleanup standards since the long-term integrity of the isolation or containment system is ensured, and the requirements for isolation or containment technologies are being met. 

The Environmental Covenant for the property is in place and continues to be effective in protecting human health and the environment from exposure to hazardous substances and protecting the integrity of the cleanup action. 

Groundwater monitoring results indicate that contaminated groundwater (that exceeds MTCA Method A groundwater cleanup levels) is contained within the property boundary and is not migrating off the property. 
Based on this periodic review, Ecology has determined that the requirements of the Environmental Covenant continue to be met. No additional cleanup actions are required by the property owner at this time. It is the property owner’s responsibility to continue to inspect the property to assure that the integrity of the remedy is maintained.

Voluntary Cleanup Program

This site was cleaned up under 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 the sites Ecology manages under legal orders.

Site use restrictions called institutional controls are in effect

Institutional controls can be fences, signs, or restrictions on how the property is used. For instance, an institutional control may prohibit installing drinking water wells or disturbing a protective cap that isolates contamination. These restrictions keep the contamination contained and keep people from being exposed to the contamination. The controls are usually listed in environmental covenants recorded with the county.

Periodic reviews are required when institutional controls are required at a site. Ecology conducts reviews to make sure the controls remain effective and the cleanup still protects human health and the environment. We conduct periodic reviews about every five years.
