�-� Kilt>lt3y Fdruaq e 2 of 15 � atld ASSOCIatB3,ltlt., + Vertical delineation of arsenic in ground water is required at monitoring well NEG MW-1. A minimum of l0 to 15 feet of separation is required between NEG MW-i and the corresponding deep well. • Resample the existing (and proposed deep) monitoring wells at the Northeast Grove. Southwest Grove • Additional ground water delineation for arsenic is warranted north of SWG MW-5 and east of SWG MW-6. • Vertical delineation of arsenic in ground water required at monitoring well SWG SHW-I. • The flow direction of the canal immediately west of the grove needs to be determined. Once established, the FDEP requested that upstream, midstream and downstream surface water samples be collected from the canal. • In-situ permeability testing (slug tests) should be performed in the Southwest Grove to establish the localized hydraulic conductivity for the surficial aquifer. The FDEP requested that a work plan be prepared and submitted for the foregoing assessment activities. The FDEP approved a time extension until March 23, 2012 to submit the results of the additional site activities. However, based on the February meeting it was acknowledged that the additional site activities would not be completed by this date; thus, submittal of the Work Plan should occur on or before this date. Additionally, the Department recommended that the work plan include a schedule for the completion of the field activities and the submittal of the corresponding report. Scope of Services KHA has prepared the following scope of services based on the foregoing project understanding. The scope of services has been developed to address the FDEP's comments in their July 14;2011 letter and the additional assessment activities discussed during the February 13,2012 meeting. Task 1—Work Plan Preparation KHA will prepare and submit a work plan for the completion of the additional site assessment activities at the Northeast and Southwest Groves pursuant to the FDEP's request. The work plan will outline the specific assessment activities to 43
