1.0 INTRODUCTION
1.1 General
This Demonstration of Compliance Report (OCR) was prepared by Handex of New England, Inc
(Handex) on behalf of the Solvents Recovery Service of New England, Inc. Superfund Site (SRSNE
Site) PRP Group to demonstrate the effectiveness of the Non-Time-Critical Removal Action No 1
(NTCRA 1) groundwater containment and treatment system at the SRSNE Site in Southington,
Connecticut This OCR presents data collected during the period of January 31 through 27,1998. The
data presented in this OCR were obtained in general accordance with the United States Environmental
Protection Agency (USEPA)-approved Demonstration of Compliance Plan (DCP) (BBL, June 1995).
The data acquisition schedule, reporting, and evaluation requirements for this and future OCRs were
described in the DCP.
The groundwater containment system is installed in the Containment Area (Figure 1), which was
defined in the NTCRA 1 Statement of Work (SOW). The containment system includes an array of 12
overburden groundwater extraction wells (RW-1 through RW-12) and a downgradient hydraulic barrier
(steel sheetpilmg) that hydraulically and physically contain overburden groundwater entering the
Containment Area from the SRSNE Operations Area. Water pumped from the containment system is
pretreated to remove metals and suspended solids, treated by ultraviolet (UV) oxidation and granular
activated carbon systems to remove organic constituents, and discharged to the Quinnipiac River. The
pre-design investigation results and the designs of the hydraulic barrier wall, extraction wells, and
treatment system are described in detail in the NTCRA 1 100% Groundwater Containment and
Treatment System Design Report (100% Design Report, BBL, January 1994). The NTCRA 1 system
was constructed between February and July 1995, and started up in accordance with the USEPA-
approved schedule on July 19, 1995.
Demonstration of Compliance Report January 31 1998 through February 27 1998
1.2 Amendments to Demonstration of Compliance Plan
Overburden compliance piezometers, CPZ-2A, CPZ-4A, and CPZ-6A were installed to provide
hydraulic head data adjacent to the south, southeast, and east sides of the hydraulic barrier wall
(Figure 1). Hydraulic head data from these three additional piezometers was used to demonstrate the
effectiveness of the groundwater containment system. Long-term dewatering of the overburden
groundwater flow system has shown that compliance piezometers CPZ-2, CPZ-4, and CPZ-6 are
appropriate to demonstrate the steady-state effectiveness of the system.
1.3 Report Organization
The remaining sections of this OCR describe:
• The acquisition and evaluation of field data used to verify the effectiveness of the groundwater
containment and treatment system as required by the DCP (Section 2.0); and
• An overview of project status regarding system adjustments and the status of appropriate or
relevant and applicable requirements (ARARs) (Section 3.0).
Demonstration of Compliance Report January 31 1998 through Fehruatv 27 1988
2.0 DATA ACQUISITION AND RESULTS
2.1 General
The data required to demonstrate the effectiveness of the groundwater containment and treatment
system were obtained in the form of hydraulic head measurements from wells and piezometers
installed in the area of the containment system, flow measurements from the extraction well array, and
treatment system pumping rates and analytical results. Field activities used to obtain these data were
performed in general accordance with the relevant standard operating procedures presented in
Appendix A of the DCP.
2.2 Containment System Monitoring
As specified in the SOW, the effectiveness of the groundwater containment system is evaluated based
on the results of a Reversal of Gradient Test, which will show that the following two requirements are
achieved during the operation of the groundwater containment system:
1. Within the Containment Area, overburden groundwater east and downgradient of the Operations
Area is flowing in the direction of the groundwater extraction wells,
2. Overburden groundwater flow is reversed and maintained in the direction of the groundwater
extraction wells within the area defined by (west of) the interpreted hydraulic divide that forms
east of the groundwater containment system.
These two requirements of the Reversal of Gradient Test were evaluated based on hydraulic head
measurements at two different groups of wells and piezometers, as discussed below in Sections 2.2.1
and 2.2.2, respectively.
Demonstration of Compliance Report January 31. 1998 through February 27. 1998
2.2.1 Reversal of Gradient Test - Requirement #1
To confirm that overburden groundwater east and downgradient of the Operations Area within the
Containment Area is flowing in the direction of the groundwater extraction wells (Reversal of Gradient
Test #1), weekly hydraulic head measurements were measured on February 4, 11, 18 and 27, 1998, at
the following overburden wells/piezometers in the vicinity of the groundwater containment system.
