Abstract:
The Loxahatchee National Wildlife Refuge (LOX) is a water-dominated ecosystem that is 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 LOX because of its designation as Outstanding Florida Waters.
Purpose:
Loxahatchee National Wildlife Refuge (LOX) maintains a separate networks of hydrologic monitoring stations (hydrostations) for measuring the stage and quality of surface water throughout the 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, and dependence on surface water depth and season.

Collection and analysis of water-quality samples at LOX was 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. Water-quality data have been collected at 10 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. The study area was extended into LOX in 2003.

Process_Description:
The objective of this project was to analyze, summarize, and report on water-quality data (field parameters and nutrients, major ions and trace metals, pesticides in sediment, and pesticides in water) collected in freshwaters in or near 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.

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.
