In July 2008, the Southeast Coast Network and the University of Georgia conducted anassessment of water and sediment quality at Timucuan Ecological and Historic Preserve as apart of the NPS Vital Signs Monitoring Program. Monitoring was conducted following methods developed by the U.S. Environmental Protection Agency as a part of the National Coastal Assessment Program and included laboratory analysis for chlorophyll a, total dissolved nitrogen and phosphorous concentrations and field measurements of water temperature, pH, dissolved oxygen, and salinity. Estimates of water clarity were made using secchi depth measurements and wereadjusted for naturally occurring regional conditions. Overall surface waters conditions at TIMU were predominately fair with 93% of sites rated as being in fair condition. Only two sites were assessed as having either good or poor surface water-quality conditions. Overall sediment conditions in the assessed benthic areas were predominately good with 83% of sites rating as being in good condition.
