Big Cypress National Preserve (BICY) and Everglades National Park (EVER) maintain separate networks of hydrologic monitoring stations (hydrostations) for measuring the stage and quality of surface water throughout their units. The data collected at these sites provides a historical baseline for assessing hydrologic conditions and making a wide range of management decisions (both internally and externally). Surface-water stage data is relatively straight-forward to analyze, both in real time and relative to historic conditions, and has typically been conducted by in-house hydrology staff at both units. Analysis of surface water-quality data is generally regarded as being more complex because of the subtleness of trends, absence of continuous data (bi-monthly for BICY and monthly for EVER), and dependence on surface water depth and season. Collection and analysis of water-quality samples at BICY and EVER are done under cooperative agreements with the South Florida Water Management District (SFWMD). Under these agreements, the Park Service collects the samples in the field and the SFWMD provides sampling equipment and laboratory analyses. EVER has been sampling water quality on a monthly basis at 9 "internal marsh" stations since 1984 as part of this program. BICY has been sampling water quality on a monthly basis at 10 "internal" stations since 1995 as part of this agreement, with water quality data at these sites extending as far back to 1988 (but not as part of the agreement). Water-quality data collected at the BICY and EVER stations has been archived and reported for short-time intervals (yearly and bi-yearly), but an analysis that covers all sampled parameters, extends over the full period of record, and provides comparisons between the two units has yet to be performed. In 2000, a study was begun by the U.S. Geological Survey to gather, edit, and interpret selected water-quality data from a variety of sources to improve the understanding of changes in water-quality in areas impacted by human activities or in more remote and relatively unimpacted areas of the Everglades and Big Cypress Swamp. One purpose is to look for long-term trends and possibly relate the trends to human or natural influences on water quality such as agriculture, drought, hurricanes, changes in water management, etc. Another purpose is to interpret data from the most remote and unimpacted areas to discern, if possible, what the natural background concentrations are for water-quality constituents that have sufficient data. An attempt will be made to find correlations between available water-quality, physical, and meteorological parameters. Such analyses of water-quality and ancillary data may assist in establishing water-quality standards appropriate for the designation as Outstanding Florida Waters in both the Everglades National Park and the Big Cypress National Preserve. Ancillary data such as precipitation, water-level, water flow, dates of major storms, and beginning and ending dates of water-control effects will be studied to relate their timing to any noticeable changes in water quality. 19591216 2000 ground condition Complete None planned -80.9 -80.5 25.7 25.2 none water quality water level hydrology nutrients nitrogen phosphorus carbon calcium carbonates major ions magnesium chloride sulfate ISO 19115 Topic Category environment inlandWaters 007 012 Department of Commerce, 1995, Countries, Dependencies, Areas of Special Sovereignty, and Their Principal Administrative Divisions, Federal Information Processing Standard (FIPS) 10-4, Washington, D.C., National Institute of Standards and Technology United States US U.S. Department of Commerce, 1987, Codes for the identification of the States, the District of Columbia and the outlying areas of the United States, and associated areas (Federal Information Processing Standard 5-2): Washington, D.

McPherson, Benjamin F. 2001 report Florida Scientist v. 64, n. 1 Orlando, FL Florida Academy of Sciences originally published in Florida Scientist, vol. 64, Winter, 2001, Number 1 http://sofia.usgs.gov/publications/papers/bottom_sed/index.html not applicable Data range from a reading in 1959 for stations P33 and P34 to 2000. Not all stations have data for every month of the reporting period. Missing data is indicated by -- in the appropriate field. The objective of this project was to analyze, summarize, and report on water-quality data collected in freshwaters in or near ENP and BCNP over the period of record. The analysis included an evaluation of seasonal and long-term trends, spatial patterns, and possible effects of hydrologic, climatic, and human-induced perturbations. Specific objectives included: (1) determination of baseline water-quality conditions relative to the designations as Outstanding Florida Waters (OFW) and Outstanding National Resource Water (ONRW); (2) an analysis of water-quality conditions across the landscape, and at internal marsh sites relative to conditions in upstream canals; and (3) an analysis of long-term trends for selected parameters, such as chloride, sulfate, and total phosphorus. Water-quality and ancillary data were collected from the files of the U.S. Geological Survey, South Florida Water Management District, Everglades National Park, Big Cypress National Preserve, some southern Florida County agencies, State of Florida agencies, and other sources of long-term water-quality and ancillary data. Available data was collected in electronic files from the original source. The intention was not to collect every available piece of data, but to collect data with the potential to detect long-term trends or lack thereof in chemical concentrations. Focus was on chemicals of environmental importance. Station location and description, and period of record data are stored for each sampling location in the USGS NWIS database. Station location and description, and period of record data are stored for each sampling location in the South Florida Water Management District DBHYDRO database. Station location and description, and period of record data are stored for each sampling location in the Big Cypress National Preserve's paper files. Data were reformatted, if necessary, for storage in a database at the U.S. Geological Survey Subdistrict Office in Tampa, Florida. When feasible, data was screened using chemical logic checks developed by Ronald Miller of the USGS in Tampa, Florida. Various graphs and statistical evaluations were used to detect correlations between variables and trends in concentration. Selected graphs and statistical results will be incorporated into a written report of the interpretations. 200206 Arturo Torres U. S. Geological Survey mailing and physical address
