Greenwich Western Middle School Field Contamination Update

GREENWICH, CT—Portions of fields of the Western Middle School field may be re-opened after soil tests results.

School and town officials along with the state Department of Public Health and Energy and Environmental Protection are currently working out the details, according to a school news release.

Areas targeted for remediation would remain fenced off and field access will not be restored, even partially until PCB contaminated soil is remediated.

PCB Delineation Results

• Langan is in the process of delineating the presence of PCBs in soil at three locations at the WMS fields. Preliminary findings have identified concentrations of PCBs above CT’s RDEC of 1 mg/kg at several locations. The REDC are set forth in Connecticut’s Remediation Standard Regulations (“RSRs”) which, although not applicable to this site, are being used as guidance. At one of the three locations, soil samples were reported to contain concentrations of PCBs above the CT significant environmental hazard (SEH) threshold of 15 mg/kg (15x the RDEC). Delineation of the PCB impacted soils is not complete, and Langan will continue to sequentially analyze delineation samples until the 1 mg/kg criteria is met. Based on the current results, additional mobilization and field sampling will be required to complete delineation activities.

At this time, the schedule for completion of PCB delineation is unknown and is contingent on the results of sampling and analyses not yet conducted.

• The fields remain fenced with restricted access.

• Langan continues to coordinate these efforts with the CT-DEEP, PCB Division.

Following the completion of soil delineation activities, Langan will develop a Remedial Action

Plan (RAP) that will include the following:

• Development and execution of action plans for the protection of students, faculty, on-site

workers, community, and the environment during soil disturbance activities;

• Excavation and off-site disposal of impacted soils;

• Placement of a highly visible demarcation barrier (e.g. orange snow fencing) between

residual site material and imported backfill material; and

• Backfilling of remedial excavation areas to grade with imported certified clean fill.

We will continue to provide updates to the community as new results and information become

available.
