new wells <strong>and</strong> from about 70 previously installed wells, <strong>and</strong> ab<strong>and</strong>onment of<br />
approximately nine wells.<br />
Investigative work at the <strong>Site</strong> was performed as part of a Remedial Investigation (RI) <strong>and</strong><br />
involved the collection <strong>and</strong> analysis of soil, soil gas, <strong>and</strong> additional groundwater samples.<br />
This data was used to evaluate the nature <strong>and</strong> extent of chemicals of potential concern<br />
(COPCs), potential risks to human health <strong>and</strong> the environment, <strong>and</strong> ascertain the need for<br />
<strong>and</strong> scope of remedial action. The scoping for the RI was initiated upon completion of a<br />
Preliminary Endangerment Assessment (PEA), which was completed in February of<br />
2005. This QAPP is designed to support remedial investigation <strong>and</strong> remedial action<br />
activities.<br />
This QAPP supercedes the DTSC-approved QAPP (Parsons, 2001).<br />
The scope of work for the assessment includes collection <strong>and</strong> analysis of soil, soil gas,<br />
<strong>and</strong> groundwater samples. The data will be used to evaluate the nature <strong>and</strong> extent of<br />
potential impacts, related risks to human health <strong>and</strong> the environment, <strong>and</strong> the need for<br />
remedial action. The scope of work for remedial action activities is to collect<br />
confirmation <strong>and</strong> waste profiling samples.<br />
1.2 PURPOSE AND SCOPE OF QAPP<br />
This QAPP sets forth quality guidelines for all activities, products, <strong>and</strong> services <strong>and</strong> is<br />
designed to ensure that all activities are accomplished in an approved, prescribed manner<br />
by technically trained <strong>and</strong> competent staff. This document establishes the QA<br />
requirements <strong>and</strong> assigns responsibility to project personnel <strong>and</strong> subcontractors for<br />
ensuring that project objectives will be achieved. This QAPP consists of the QA<br />
program requirements that are responsive to all guidance documents referenced in<br />
Section 1. Quality requirements specified in this document are tailored to the needs of<br />
this assessment project.<br />
1.3 PROJECT OBJECTIVE<br />
The purpose of this assessment work is to characterize the nature <strong>and</strong> extent of COPCs at<br />
the site <strong>and</strong> identify whether the potential for significant adverse human or ecological<br />
impacts exist. The site characterization will support the evaluation of potential school<br />
use of the site. The purpose of remedial action work is to confirm that the remedial action<br />
objectives have been achieved in order to support a “No Further Action Determination”<br />
by DTSC.<br />
1.4 PROJECT ORGANIZATION AND RESPONSIBILITIES<br />
This project will be accomplished with project personnel <strong>and</strong> various subcontractors.<br />
Subcontractors will include drillers, surveyors, <strong>and</strong> analytical laboratory(s). The<br />
responsibilities of the positions relevant to project QA/QC are summarized below <strong>and</strong><br />
displayed in Figure 1-1.<br />
