Groundwater quality monitoring identified the presence of increasing arsenic concentrations within groundwater. FDEP required the preparation of an Evaluation Monitoring Report, Site Assessment, and Corrective Action Plan to address this issue. |
| Scope: |
- Perform limited historical site land use assessment with historical aerial photographs and maps for source of arsenic.
- Utilize rotary and Geoprobe drilling rigs to collect soil samples and install monitoring wells.
- Collect soil and groundwater quality samples pursuant to FDEP SOPs.
- Perform slug testing to calculate groundwater seepage velocities.
- Conduct area survey for wells and potential pollution sources.
- Prepare a report fully documenting investigative methods, results and conclusions regarding site conditions pursuant to FDEP Rules 62-701 and 62-780, F.A.C.
- Evaluation and Site Assessment reports showed that reductive dissolution, or the “shadow effect” was the primary cause of arsenic groundwater contamination.
- Monitored Natural Attenuation recommended in lieu of active remediation.
