Crownhill Elementary School Bremerton SD

Annual performance and monitoring reports for 2015 and 2016 are now available. These reports describe the results from the following activities conducted for these years:

·        groundwater and petroleum product monitoring

·        petroleum product removal from groundwater

·        Site inspections including pavement conditions

The wells continue to extract some amounts of petroleum from groundwater and groundwater contamination is not moving off-site.  The remedy continues to comply with the requirments of the final cleanup action plan and remedy implementation plans.

The Site was originally used for mining of sand and gravel during the 1930s. The resulting mining pits were used as a landfill for various materials including municipal and industrial wastes. Some of the industrial wastes were reported to be imported from the Puget Sound Naval Shipyard by the US Navy, including sandblast grit, scrap metal, asbestos insulations material, metal shavings, and fire bricks. The original Crownhill Elementary School was constructed on the Property in 1956. The school partially burned down in 1993. The remaining building structures were demolished after the fire in 1993. In 1994, site work for a new Crownhill Elementary School was started on the Property. During site preparation and utility excavation work, some soils were identified as known or suspected contaminated soils. Contaminates soils removed during construction were disposed of at an appropriate landfill. The new school opened in 1996.

Contaminants of Concern

An initial investigation detected contamination exceeding state cleanup standards in soil typically at depths greater than 3 feet below ground surface.  These contaminants include petroleum products, household waste, lead and industrial solvents.  The proposed interim action is designed to restore the one area where these contaminants exceeded unrestricted land use cleanup levels at ground surface.
