I <br />L7 <br />P, <br />� I <br />11 <br />I. INTRODUCTION <br />Part 2 presents the surface- and ground -water monitoring plan for the <br />Corral Hollow Sanitary Landfill in accordance with Subchapter 15 <br />requirements. The pertinent background information, including a <br />description of the site and hydrogeologic conditions beneath the site, <br />is presented in Part 1 of this document. Part 2 explains the proposed <br />Subchapter 15 surface- and ground -water monitoring network, sampling <br />and analysis plan, process for evaluation of ground -water monitoring <br />data, and procedure for determining ground -water direction and veloci- <br />ty. <br />In October 1987, EMCON implemented a ground -water exploration program <br />to further define subsurface conditions, establish depth to the <br />regional ground -water table, install a ground -water monitoring well, <br />and provide baseline soil and ground -water chemical data. The results <br />of this program are presented in EMCON Associates (1988). The follow- <br />ing monitoring plan was developed using the findings of this explora- <br />tion program. It is designed to detect the migration of waste con- <br />stituents from the landfill to ground and surface water near the site. <br />The Corral Hollow Sanitary Landfill is unlined. Therefore, unsaturat- <br />ed (vadose) zone monitoring is not required under Section 2559(a), <br />Subchapter 15, Title 23 of the CAC, and no unsaturated zone monitoring <br />is proposed for the site. Also, unsaturated zone monitoring is not <br />believed to be feasible at the site (see Part 1, Section III). <br />Chemical characterization of the vadose zone was performed for Boring <br />MW -1 and will be performed for additional borings at the site as <br />described in Part 1, Section III. <br />18 <br />Mon Associates <br />
