DEBRAAL DEPUTY-COUNTY ATTORNEY t Kimley-Hom and Associates, Inc. Exhibit A to Amendment Number 1, dated January 9, 2013 Project Understanding hi response to the Florida Departinnent of,Environmental Protection' s (FDEP) December '11, 2012 'correspondence, Kimley-Horn and Associates, Inc. (KHA) will conduct additional ground water sampling at the Shadowbrook Estates Site (the "Site"). The Consultant shall perform the following Additional Services: Task 1 — Ground Water Sampling The existing monitoring wells at the Northeast Grove and Southwest Grove will be re=sampled for total dissolved solids, arsenic and/or lead. Ground water sampling will be performed in accordance with the FDEP's Standard Operating Procedures. KHA will provide notification to the FDEP's;Southeast District 48-hours prior to commencement of the ground water sampling. Depth to ground water measurements will be made and recorded for each monitoring well prior to sampling. The depth to ground water at each monitoring .well will be measured with an electronic water level meter. Additionally, water level measurements will be recorded at the upstream and downstream benchmarks established for the canal along the western side of the Site. The water level measurements will ultimately be used to establish the localized direction of ground water flow across the Site. Prior to sampling, each of the monitoring wells will be purged to facilitate collection of representativesamples from the water-bearing formation. The monitoring wells will be purged using a peristaltic pump and low4low techniques. Throughout the. purging process„ field parameters will be measured and recorded on ground water sampling; logs. The measured field Ii parameters will include pH, specific conductivity, dissolved oxygen, oxidation/reduction potential, and turbidity. Ground water samples Will be collected from each monitoring well once the field parameter readings have stabilized indicating that fresh formation water . is ;entering the monitoring well . The: ground water samples will be collected in laboratory supplied containers with the appropriate preservatives.. Following collection, the ground water samples will be placed on IM=d prepared to transportto the designated laboratory under chain-of-custody protocol. Astoted in KH 's October 16, 20t2 letter to the FDEP, the ground water across the site contains elevated concentration. of tannins which impart elevated turbidity of the :ground water samples. As such, both total and dissolved metals samples will. be collected iirnn the Site: The dissolved metals samples will be collected using . a dedicated; 1 .0-m cor in-line filters pursuant to the FDEP's SOP DEMOP-00:1/01 FS 2225 . At the Northeast Grove area ground water samples will be collected. from monitoring wells NE& MW4R, NIB&MW- t Deep, NEG .MW 2, NEG-MW-3 and NE&MW4. The corresponding ground water samples . will be analyzed for total dissolved solids and total and dissolved arsenic. The eleven monitoring wells at the Southwest. Grove area: SWG-SRW- 1 ,, SING-SHWMW- tDEEP,, SWG-MW- 1 , SWO MW4, . SWG-MW4 SWG-MW 4, SW&MW4, SWG-MW4, SW&MW4v SWG-MW=100, and SWG-MW401, will be analyzed for° total dissolved solids, and . total and dissolved arsenic and lead. In addition to the 17 ground water samples, QA/QC samples Wmley-Horn and Associates, Inc. consisting of 2 blind duplicate samples and. 2 equipment blanks will be collected pursuant to the FDEP's SOP. The ground water samples will be analyzed on a normal. (7 to 10-day) turnwaround time. Task 2 — Ground Water Monitoring Report Upon receipt of the laboratory data, KHA will prepare and submit a Site Assessment Status Report to the FDEP. The report will summarize the methodology and results . of the additional ground water sampling. The Site Assessment Status Report will include the following: • A. description of the methodologies employed for the additional sampling: • A discussion of the groundwater quality data collected from the Site. • Tabular summaries of the ground water quality data. • Tabular summary �of the depth to ground water measurements. • Scaled drawings depicting the location, of the existing and proposed monitoring wells. • Scaled ground water contour maps. • Copies of the laboratory analytical data. The report will be signed and sealed by a Professional Geologist licensed in the State of Florida. The County will be provided with three hard copies and one electronic copy of the report. Additionally, one hard copy and one electronic copy of the report will be submitted to the FDEP. For the Additional Services set forth above in Tasks i and 2, Client shall pay Consultant the lump sum . labor amount of $8500.00, exclusive of sampling expenses. Expenses are anticipated to be approximately $3000.00.
