Surface and Groundwater Monitoring of Southern Biscayne Bay

Biscayne National Park » Surface and Groundwater Monitoring of Southern Biscayne Bay » Document List

The surface water stations in Biscayne Bay shall measure conditions just above the sediment surface. All stations, with the exception of the Card Sound Road canal station, shall be automated with one set of temperature and conductivity sensors installed horizontally, approximately 1 foot above the sediment surface (Appendix B). Stations in the Biscayne Bay not co-located with groundwater stations will not have telemetry and a surface water stage recorder. Sampling stations in Table 2-5 shall be automated and instrumented similarly to the CCS stations. This will allow for the determination of water level, temperature, and specific conductance at each site.

Data from each surface water station discussed previously shall be collected at 15-minute intervals from the top of each hour and either manually or remotely uploaded to a database. This monitoring strategy shall allow a continuous assessment of specific conductance and temperature changes in Biscayne Bay and canals in the areas surrounding the FPL Turkey Point Power Plant. The stage sensors shall be tied to an established datum (NGVD and NAVD). All sensors shall be inspected and cleaned as needed to meet QA/QC requirements.

In addition to the proposed automated monitoring, quarterly monitoring at each surface water station shall consist of field parameters, major ions, and the CCS tracer suite, as listed in Table 2-1. Semiannual monitoring at each surface water station shall consist of all of the above parameters, as well as nutrients. All applicable samples shall be analyzed in accordance with Chapter 62-160 F.A.C. at an FDEP-approved laboratory facility capable of analyzing samples with a wide specific conductance range (including hypersaline waters). Additional data from other entities, such as BNP, NRC, USACE, EPA, NOAA, DOI, NPS, DOH, USGS, FWS, DERM, other local governments, and the SFWMD will be added to the information collected from this effort to form a more comprehensive understanding of this area. BNP monitors salinity at 34 sites in the area at the same 15-minute sampling frequency (Bellmund et al. 2007), and the sites around the CCS (BISC08B, BISC12B, and BISC13S) will be used to complement the monitoring efforts. Information available from the sampling network in BNP, Audubon Society's nearby sites, and the SFWMD Water Quality sampling network will be reviewed for relevance and applicability in the inclusion of data reporting. Other data that will support this monitoring effort include the SFWMD operations of the S- 20 structure, since that may affect the water quality at TPSWC-4.
