RE: Remedial Action Plan for Dzen Tree Farm subdivision
Barber Hi11 Road and Maskel Road,South Windsor
Dear Mr.Folger:
As requested by the Town of South Windsor, Zuvic Associates, Inc. (Zuvic) on behalf of
Mannarino Builders, Inc. (MB), has prepared this remedial action Plan
pesticide contaminated soil identified at the above-referenced site. Th RAP will presedntt the procedures to be implemented to cleanup areas where elevated concentrations of residual
pesticides need to be reduced to acceptable standards.
The site, located east of Barber Hill Road, is the location of the proposed. Dzen Tree Farm
b, subdivision to be built by MB, and was historically used for agricultural
ses with crops
including strawberries, blueberries, Christmas trees, and potatoes. To assesssoil conditions
related to historic agricultural use, soil,samples were collected°in November 2006, October and
November 2007, and February 2008 and submitted to a Connecticut certified laboratory for
analysis of pesticides and arsenic. The sampling results were published in reports dated
November 2007 and February 2008.
Remediation Target Arias
The sampling analytical results were compared to the Connecticut Department of Environmental
Protection (CTDEP) Remediation Standard Regulations
criteria esDEC for �R) residential direct exposure-
(R ) pesticides and herbicides. Sample locations where concentrations of
pesticides or arsenic were above the ResDEC were included on a summary table and highlighted
on the attached Figure 1. Although the RSRs are not applicable to current or former agricultural
properties, such as this site,they were used to broadly assess soil quality and to be a consery ative
baseline as to what concentrations may be considered acceptable by the To South Windsor.
Remediation target .areas were determined by first calculating the horizontal limits of
contaminated soil and extending vertical contamination limits to approximately four to six inches
below the deepest depth of reported soil contamination. The horizontal limits were calcl at by
drawing lines through points that were equidistant from the most adjacent `clean' and u ed
