Crownhill Elementary School Bremerton SD

The Site includes both the Crownhill Elementary School property at 1500 Rocky Point Road (Parcel No. 152401-2-027-2005, the northern parcel) and the northern portion of the Bremerton United Methodist Church property at 1150 Marine Drive (Parcel No. 152401-2-098-2009, the southern parcel).

The Site was used for sand and gravel mining up to the 1930s. After excavation stopped, the gravel pit was used as a municipal/industrial landfill in the 1930s and 1940s. Site investigations show that the depth of fill extended from 15 to 40 feet below grade. Bremerton School District acquired the northern Site parcel from Kitsap County in 1954. Construction of the current school building was completed in 1996. The Methodist Church likely acquired the southern Site parcel in the 1960s and the church building was constructed in 1965.

A series of investigations were conducted at the Site between 1993 and 2012, finding concentrations of hazardous substances on the property at concentrations that exceeded state cleanup levels. Cleanup actions were completed under a 2015 Agreed Order (AO, No. DE 11107), and included removal and capping of surface soils, continuous operation of the School HVAC system during building occupation, groundwater and soil gas monitoring, and gauging and removal of petroleum free product from Site monitoring wells.

Institutional controls in the form of environmental covenants were also part of the cleanup actions to place certain restrictions on the property, provide requirements for protecting the remedy, and prevent exposures to remaining contamination. A periodic review is conducted every five years to evaluate the effectiveness of the cleanup and confirm that it is still protective of human health and the environment.
