SUBJECT: Work Order No. 9 to Geosyntec for One Year of Groundwater Monitoring/Reporting at the Former South Gifford Road Landfill
__________________________________________________________________
BACKGROUND
In accordance with the requirements by the Florida Department of Environmental Protection (FDEP), the former South Gifford Road Landfill site requires continual groundwater monitoring activities and regulatory oversight to show that the County and Solid Waste Disposal District (SWDD) are proactively taking efforts to remediate the site.
FDEP requires submittal of an annual groundwater monitoring report no later than February 28, 2026 (to document results of the semi-annual sampling events). Previous sampling, reporting, and remedial events performed by Geosyntec have been completed on schedule and within budget. In addition, FDEP approved Geosyntec’s 2023 recommendations to reduce the monitoring network by 38% and change the reporting frequency from semi-annual to annual.
Accordingly, staff requested the attached proposal from Geosyntec to provide routine groundwater monitoring and reporting for a one-year period and annual pollution remediation liabilities evaluation.
ANALYSIS
Geosyntec’s proposal includes two semi-annual monitoring events and one annual reporting event for the routine groundwater monitoring program required by FDEP, and preparation of an annual pollution remediation liabilities evaluation. Geosyntec’s proposal consists of five phases as follows:
|
Phase Description |
Budget |
|
Phase 1: Project Management |
$7,663.20 |
|
Phase 2: Meetings/Regulatory Interaction |
$4,911.60 |
|
Phase 3: Annual Pollution Remediation Liabilities Evaluation |
$6,466.34 |
|
Phase 4: Semi-Annual Sampling Activities |
$61,982.42 |
|
Phase 5: Data Evaluation and Semi-Annual Reporting |
$11,877.58 |
|
Total |
$92,901.14 |
Phase 1 includes project planning and management responsibilities. Phase 2 includes meeting attendance and interaction with regulatory agencies. Phase 3 includes preparation of the annual environmental liability evaluation in response to Governmental Accounting Standards Board Statement No. 49 (GASB No. 49), Accounting and Financial Reporting for Pollution Remediation Obligations, which requires the inclusion and calculation of pollution remediation obligations. Phase 4 includes field preparation, groundwater sampling, and water level measurements during two routine groundwater monitoring events. Phase 5 includes data evaluation and annual reporting.
BUDGETARY IMPACT
Funding for this work, in the amount of $92,901.14, is budgeted and available in the Optional Sales Tax/Landfill/Other Contractual Services/Landfill Groundwater Testing account, number 31521734-033490-03004, which is the one-cent sales tax fund used for infrastructure needs of the County. Costs associated with the landfill are authorized uses of the one-cent sales tax, in addition to infrastructure.
STAFF RECOMMENDATION
