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
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
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.
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
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.
