Description:
Abstract:
The Big Cypress National Preserve (BICY), the Everglades National Park (EVER), and Loxahatchee National Wildlife Refuge (LOX) are water-dominated ecosystems that are susceptible to water-quality impacts. A comprehensive analysis of historical water-quality and ancillary data is needed to direct the restoration of the Everglades and the adoption of water-quality standards in BICY, EVER, and LOX because of their designations as Outstanding Florida Waters.
Purpose:
Big Cypress National Preserve (BICY), Everglades National Park (EVER)), and Loxahatchee National Wildlife Refuge (LOX) 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, EVER, and LOX 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 Water-quality data collected at the BICY and EVER stations has been archived and reported for short-time intervals (yearly and bi-yearly), but an analysis that covers all sampled parameters, extends over the full period of record, and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 parks has yet to be performed. Water-quality data have been collected at 14 internal marsh sites in LOX by the U.S. Fish and Wildlife Service for over 10 years. These samples have been analyzed by SFWMD laboratory.

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. The initial study area was in BICY and EVER; the study area was extended into LOX in 2003.

Data_Quality_Information:
Logical_Consistency_Report: not applicable
Completeness_Report:
Stations in Big Cypress National Preserve (BICY) have bi-monthly records while the records for Everglades National Park (EVER) and Loxahatchee National Wildlife Refuge (LOX) are monthly. The period of record varies from site to site ranging from 1932 for stage at well S-196, 1953 for Tamiami Trail discharge, 1955 for rainfall, 1959 for sulfate and stage at site P-33, and 1960 for most internal sites at EVER.

Process_Description:
The objective of this project was to analyze, summarize, and report on water-quality data collected in freshwaters in or near ENP, BCNP, and LOX 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: chloride, sulfate, total phosphorus, total nitrogen, and specific conductance.

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, the U.S. Fish and Wildlife Service, 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 and 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 St. Petersburg, 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.

Process_Date: 2005
Process_Step:
Process_Description:
Work planned for FY 2004 includes evaluation of baseline water-quality conditions at selected index sites in Loxahatchee National Wildlife Refuge (LNWR) and Biscayne Bay National Park (BBNP). The baseline water-quality in LNWR will be evaluated and a summary of water quality conditions published in an interpretative report. Based on consultation with scientists at BBNP, water-quality index sites in the Park will be selected and compilation started on a database of historical water quality at these sites.

Completion of the database and a report for Biscayne Bay National Park are planned for FY 2005.
