Expanded Site Review of the Proposed Strecker Forest Development, Wildwood, Missouri
INTRODUCTION
The U.S. Environmental Protection Agency (EPA) is conducting an investigation of environmental conditions at the proposed Strecker Forest subdivision located on Strecker Road in Wildwood, Missouri. For this effort, EPA is assisted by the Missouri Department of Natural Resources (MDNR), the Missouri Department of Health and Senior Services (MDHSS), and the Agency for Toxic Substances and Disease Registry (ATSDR, part of the U.S. Public Health Service).
EXPANDED SITE REVIEW
To address public concerns that have been raised by recent studies, EPA is conducting an Expanded Site Review to further characterize environmental conditions in the vicinity of the proposed Strecker Forest subdivision. This investigation is intended to supplement past studies and provide a comprehensive data set that can be used to assess the suitability of the property for residential development. The Expanded Site Review will also more fully characterize the hydrogeology in the area and the potential for ground water conditions to affect proposed and existing residences.
The scope of the current investigation will include:
- Geophysical investigation for metals
- Exploratory trenching
- Collection of surface soil samples using an incremental sampling protocol
- Collection of subsurface soil samples from borings
- Collection of interior dust samples from existing structures
- Installation of ground water monitoring wells
- Measurement of static water levels in new and existing monitoring wells
- Collection of ground water samples from new and existing monitoring wells
- Hydraulic conductivity testing
- Dye tracing studies (DTS)
Detailed information regarding the above procedures is available in the Final Expanded Site Review Work Plan, available online at www.epa.gov/region7/cleanup/strecker_forest.
EPA field work associated with the current investigation began September 6, 2011, and will take approximately one month to complete. This time frame includes initial site surveys and all sampling activities.
The timing of individual field activities may vary due to conditions on the ground.
Some elements of the investigation will continue beyond the initial field work, including the ongoing hydrogeological investigations. A final report of the Expanded Site Review is anticipated in January 2012.
BACKGROUND
The proposed Strecker Forest subdivision is located adjacent to the former Bliss-Ellisville Superfund site in Wildwood, Missouri. The Superfund cleanup of the Bliss-Ellisville site was conducted by EPA in 1996 and involved removal and off-site disposal of dioxin-contaminated soil and other hazardous wastes that were formerly present on the property.
The 18.3 acre tract proposed for residential development includes a small 0.15 acre portion that was involved in the 1996 Superfund cleanup of the adjacent property. This 0.15 acre area is located in a planned preservation area away from the proposed home sites in the northwest corner of the property. Soil sampling conducted following the 1996 cleanup confirmed that conditions in this area were protective for unrestricted use, including residential development.
