Current Water-level Conditions in South Florida

The stations presented in these web pages are continuously monitored by on-site equipment. The data collected are held on-site until transferred by satellite to USGS computers. These data transfers are scheduled every 4 hours. Considering transfer and analysis time, the data on this page are expected to be current to the date and may be updated more frequently as conditions require. The data presented are provisional, as they are retrieved directly from the USGS database without final quality assurance/quality control review.

For more information on the methods used and the data analyzed, the project report is available on this website. A PDF version of the report (download 6.3 MB) is also available.

Current Water-level Conditions in South Florida (de-trended) - The data presented in the image maps are the 7-day averages of the daily values (daily maximum water level for ground water in South Florida) as compared to the historical (the last 35 years, as available) data from each station. As discussed above, the historical data have been analyzed to determine the existence and extent of any long-term trends. Long-term trends are mathematically removed from the data in order to present current data in a historical context without the skewing caused by such trends.

Current Water-level Conditions in South Florida (without trend removal) - The data presented in the image maps are the 7-day averages of the daily values (daily maximum water level for ground water in South Florida) as compared to the historical (the last 35 years, as available) data from each station. In these pages, long-term trends are not considered. Plots of current data against the distribution of historical data may therefore show current water levels abnormally low during a period of good water supply or abnormally high during a drought in cases where there is a long-term downward or upward trend in water levels.

End-of-Month Water-level Conditions in South Florida

Prior to September 2000, the FISC-WRS produced an End-of-Month (EOM) report summarizing water-level information throughout South Florida. The majority of these wells were not monitored in real-time via satellite telemetry, so this was the primary method of disseminating the provisional data from these sites to regional water managers. Because of the widespread availability of the World Wide Web (WWW), this site has replaced the EOM report.

The stations presented in these WWW pages are continuously monitored by on-site equipment. The data collected are held on-site until downloaded by a USGS technician during a monthly site visit. These visits are scheduled every 4-8 weeks, based on operational requirements, and so the data on this page are only generally expected to be current up to the second month before the current month. In any case, the data presented are provisional, as they are retrieved directly from the USGS database without final quality assurance/quality control review.

Water-level Conditions for the End of <Month> in South Florida (de-trended) - As with the real-time pages, the historical data (last 35 years, as available) from each well has been analyzed to determine if there is a long-term trend in the data. At sites where there has been a long-term change in water levels, the long-term trend is mathematically removed from the data in order to present current data in a historical context without the skewing caused by a long-term trend.

Manual Water-Level Measurements in South Florida

With the development of websites to display data from real-time and non-real-time, continuously-monitored groundwater stations, it was decided that the FISC-WRS should also produce a site displaying data from periodically-measured groundwater sites. By this time NWISWeb was able to provide periodic groundwater levels as well as water quality parameters, neither are presented with a historical analysis of the data. This site is intended to fill the gap between the existing analytical sites provided by FISC-WRS and the historical measurements data available through NWISWeb.

The stations presented in these WWW pages are periodically (generally monthly, quarterly, biannually, or annually) visited for the purpose of collecting manual tapedown (measurement of water level) or chloride concentration data. In some cases, these stations are also continuously monitored for groundwater elevation at the sites. This will be noted on the station page and such sites should also be available on the real-time and non-real-time pages. For the majority of the remaining sites, the data on this page are only generally expected to be current up to the second month before the current month. Also, such sites will include two-year duration plots of the most recent data compared to the historical average water level calculated for the site. In any case, the data presented are provisional, as they are retrieved directly from the USGS database without final quality assurance/quality control review.

Saline Intrusion Monitoring, Miami-Dade County, Florida

This internet map service has been developed as a part of a larger study investigating both the current extent of seawater encroachment into the Biscayne Aquifer and the hydrogeologic context in which intrusion may be occurring. The study area itself includes most of metropolitan Miami-Dade County, Florida.

Saline Intrusion Monitoring, Miami-Dade County, Florida - This portal has the following goals:

• provide access to all of the salinity information collected as part of this project,
• provide access to data being collected from the modified USGS / Miami-Dade County monitoring network as it evolves,
• provide a resource for integrating the geographic data sets from other researchers and agencies working in the area, and
• provide an improved means of evaluating salinity changes in the Biscayne Aquifer that will occur even after the project has been completed.
  

Because an internet map service is not entirely accessible to the public under various conditions, accessible support to this site is available through: Salinity and Chloride Data, Sites in Miami-Dade County, Florida, a sub-page of Salinity and Chloride Data, South Florida. Access to chloride data collected by Florida Keys Aqueduct Authority that were used in the estimation of the 2008 inland extent of saltwater intrusion in Miami-Dade County, FL can be located through the Hydrographic Internet Map Service Data Library.

Salinity and Chloride Data, South Florida - As discussed, this site has been developed as an extension of the existing map-based data access pages. Because there is concern that interactive map technologies, such as ArcIMS, are not fully accessible to many citizens, the infrastructure on which the preceding sites were built has been retained. Because of the shared architecture with the groundwater conditions sites, the study area for this website includes the southwest coastal areas and more of the southeast coastal areas of peninsular Florida than the Miami-Dade County study are of the ArcIMS portal.
