SITE DESCRIPTION

The school is located on former orchard property and was subject to historical pesticide applications.  Soil samples taken in 2002 confirmed lead and arsenic at concentrations exceeding state cleanup levels.

After a Site Hazard Assessment, the Site was ranked a “3” on the Hazardous Sites List. The Hazardous Sites List is a statewide list of contaminated properties.  Sites can be ranked from a “1” to “5”.  A rank of “1” is the highest level of environmental concern compared to other sites on the List, and a rank of “5” is the lowest.


CLEANUP ACTIVITIES

During the summer of 2008, Ecology conducted a cleanup and placed all contaminated soils under a geotextile fabric barrier.  Then, six inches of clean topsoil were placed on top on the barrier fabric.  This cleanup method, referred to as capping, is cost-effective and prevents human exposure to contaminated soil.
 
Following cleanup, an environmental covenant was recorded for the property with the Chelan County Assessor.  The purpose of the environmental covenant is to provide a permanent legal record of the contamination that remains on the property, and to prevent activities at the site that might disturb or damage the soil cap.


CLEANUP COMPLETE

Based on sampling results and the cleanup completed, Ecology has determined the site does not pose a threat to human health or the environment.  Ecology issued a No Further Action determination. The Site has been removed from the Hazardous Sites List.
