The Trust performed selective soil testing to investigate the presence of Army-era debris found beneath the ground surface in the Lendrum Court Area. The subsurface debris includes abundant glass, ceramics, and terra cotta, as well as lesser quantities of cobbles, brick, charcoal, wire, metal, small animal bones, and burned wood and ash. Lead and other chemicals were detected at concentrations that could potentially pose a human health or ecologic risk if individuals are exposed to contaminated soils through ingestion, inhalation or dermal contact. Of particular concern is the presence of glass at the ground surface. The glass and contaminated soils have been brought to the ground surface via gopher activity, increasing the potential for human exposure.
The Trust reported the sample results for the debris fill to the California Department of Toxic Substances Control (DTSC). The results are described in a report titled Lendrum Court Investigation Summary Report and Risk Screening Evaluation. Under the direction and oversight of the DTSC, the Trust is conducting additional investigation to define the extent of debris soils and to develop action plans to prevent human and ecologic contact with the debris.
The Presidio Trust has implemented and is maintaining temporary actions to minimize potential human exposure to the debris found in Lendrum Court while permanent remedial actions are developed.
Spring 2014 through Fall 2014
Under the direction of DTSC, the Presidio Trust conducted additional sampling and testing in the North Fort Scott neighborhoods and within Lendrum Court to delineate the full extent of the debris, confirm what chemicals are of concern, and determine if any risk is posed to individuals living in and visiting the neighborhood. The results of these investigations are presented in the Lendrum Court Remedial Investigation Summary Report.
Fall 2014 through Spring 2015
Based on the extent of debris defined in the Remedial Investigation Report, the Trust identified alternatives to mitigate human and ecologic risk associated with the waste debris. The preferred alternative is to consolidate the waste, cover the waste with a cap, and implement land use controls to ensure the cap is maintained and protects residents and wildlife from exposure to the debris.
Summer 2015 through Summer 2016
The Trust and DTSC have developed a Draft Removal Action Work Plan to address the issues. After the document becomes final, the Trust will implement Phase 1 of remediation in 2015. Phase 2 will be completed in summer 2016.
